Why do I revise older feature articles on this site

I will be working through some of the feature articles and buyers’ guides on this site and refreshing the content in them.

Why I need to do this with these articles is primarily to bring the content up to date with the way consumer and small-business information technology is progressing. It has become such a situation that the technology that was referred to in an article may have been improved upon by newer and better technology.

Previously, I just revised the laptop computer buyer’s guide because of the new classes of laptop and notebook computers that had evolved over the past two years such as the Ultrabooks.  I will be releasing a revised version of the article about extending your wireless network due to the new capabilities that access points and wireless routers have such as dual-band 802.11n operation and WPS easy-setup functionality.

This is not an intention to regurgitate stale content but to bring advisory articles up to date with newer technology as is required of a technology-focused Website.

Product Review–Dell XPS 13 Ultrabook

Introduction

I am reviewing the Dell XPS 13 Ultrabook which is Dell’s main foray in to the  Ultrabook thin-and-lignt market. The model I am covering is the more expensive unit which has a 256Gb solid-state drive

There are economy model of this computer, one with Intel i5 processor and 128Gb solid-state drive as the cheapest option and another mid-range model with an i5 processor and a 256Gb solid-state drive.

The computer itself

Aesthetics and Build Quality

Like other Ultrabooks,, this Dell XPS 13 is very light and doesn’t take up much room in your shoulder bag. The unit is wrapped in an aluminium finish with the keyboard surrounded in a rubber-feel panel which doesn’t feel as sweaty to use.

At times the computer does feel warm underneath after a long session of use. This is more noticeable around the back edge and is more so if you are engaging in video-heavy or CPU-heavy tasks.

User Interface

Dell XPS 13 UltrabookThe Dell XPS 13 Ultrabook is equipped with an illuminated keyboard. But this keyboard does feel hard and has that cheap calculator-keyboard feel.  At least you can still touch-type on the keyboard easily. It als misses distinct keys for page-up / page-down functions which can be confusing when you are browsing a Web page.

The XPS’s trackpad doesn’t have distinctly marked-out buttons for selecting or confirming the options. This is similar to what is accepted on the MacBook computers and  it can be hard to locate the correct buttons by touch when you need to click or right-click that option.

The trackpad doesn’t respond to the double-tap = select gesture which is a common gesture for nearly all laptop trackpads.

Audio and Video

Right hand side connections – USB 2.0 port and DisplayPort

The Dell XPS 13 Ultrabook performed properly, responsively and smoothly with video content. This included action content that I viewed as part of a video-on-demand show. It may not be all that suitable for some activities like intense gaming.

I used this Ultrabook with the previously-reviewed Turtle Beach headset and found that you need to enable the Realtek Waves MAXXAudio all the time to keep “punch”in the sound even for the TV show. Of course, I would not expect much for the integrated speakers especially if you want to play music or desire movies and games with the effects being there.

Connectivity, Storage and Expansion

Dell XPS 13 Ultrabook left hand side connections - power, USB 2.0, 3.5mm audio in-out jack

Left-hand side connections – power, USB 2.0, 3.5mm audio input-output jack

The Dell XPS 13 is equipped with two USB 2.0 connectors, a 3.5mm audio input-output jack and a DisplayPort port for monitors and video adaptors. These are its only connectors, in order to achieve a very slim notebook.

This Ultrabook has a 256Gb solid-state drive as its secondary storage and, unlike mist laptop computers that I have used or reviewed, doesn’t come with a memory-card slot. This would be considered an omission for those of us who take the memory card out of our digital cameras as part of transferring our images to a computer.

Battery life

The battery does live up to the expectations for an Ultrabook’s battery with it being half-empty aftar a good afternoon’s worth of hotspot surfing.

Even viewing 1.5 hour’s worth of on-demand video had the battery meter registering 45%. Like the Acer Aspire S3 Ultrabook, the Dell XPS 13 doesn’t support a hibernate mode for whenever you are not using the machine. Instead, the computer will stay in a “sleep mode” for a few hours then enter a “deep sleep”mode until you power it on.

Limitations and Points Of Improvement

The Dell XPS 13 Ultrabook could benefit from a pair of USB 3.0 sockets rather than USB 2.0 sockets so as to take advantage of external USB hard disks. As well, it could be equipped with an HDMI socket or be supplied with an HDMI adaptor so that it can connect to just about every flatscreen TV in circulation.

Dell XPS 13 Ultrabook rear viewAs I have said before, it definitely misses the SD card slot which would be important with digital-camera users who prefer to “remove the film” from the digital camera and this could be installed in the lid if you needed to balance out the space for the various hardware parts..

Conclusion

I would recommend that people purchase the Dell XPS 13 Ultrabook as a secondary notebook computer to use while travelling or using your favourite cafe, bar or hotel lounge as your second office. This assumes that you have a larger laptop or desktop as your main computer where you do most of your work on. It could be sold for a bit cheaper based on the options that it has even though the solid-state drive is sold at a premium.

Also, I would recommend that people who have digital cameras purchase an SD card reader if you you need to remove the card from the camera to download pictures. As well,you would need to know where the computer is at all times because the machine isn’t equipped with a lockdown slot.

What can you do about people who use the Social Web to menace

Articles

Twitter, Facebook must be more diligent | Technology | BigPond News

Expert says Dawson broke the first rule of social media: don’t feed the trolls | Sydney Morning Herald

My Comments

The Charlotte Dawson saga that has been over the Australian news media over the last week has become a wake-up call regarding the nature of the Social Web and the Internet in general when it comes to the ability to leave unverified irrational comments against people or organisations.

This is where social networks, bulletin boards, forums and similar services are used as a platform to launch an attack against a person. Here, it can manifest in ways such as a caustic remark left on a Facebook profile or a forum; through a barrage of tweets or instant messages of abuse fired at a person or, at worst, a Facebook Page, YouTube video or something similar can be set up to pillory that person.

Even before the Social Web became mainstream, there was the issue of free Web hosts and the “export to HTML” function in recent word processors and affordable desktop-publishing software being used to quickly set up defamatory Web sites against people. This situation was then underscored by the use of cost-effective camera-equipped mobile phones to create distasteful videos to appear on these sites or to send across to others via email or MMS.

Some press articles raised the issue of how easier it has become to leave improper comments on the Social Web, Web-hosted forums and the like without being traced back easily. This is even though most of these services have mechanisms for the Webmaster or others in charge to control scurrilous behaviour, including a reporting mechanism for others who are aggrieved by the behaviour to let those in charge know. As well, these mechanisms are underscored by the terms and conditions that users have to assent to when they become a member of these services.

Even before the rise of the Internet, there was common advice that was offered regarding nuisance phone calls and similar behaviour involving communications services/ For example, one was advised to simply to hang up on a nuisance call and, if the activity persisted, to report the matter to the telecommunications company and the police.

This was also underscored by most countries having laws in place that proscribes the use of a “common carriage service” to harrass, menace or threaten others. The reference to the “common carriage service” is a legal term used to describe telephone, post or similar services used by everyone as a communications tool.

What can you do

What most of us have to be aware of is not to satisfy the cyber-bully’s wants by leaving responses to the caustic remarks or passing on the comments in the common space that the platform offers.

If the behaviour persists, we have to know how to “block” or “unfriend” the troublemakers in the case of social media. There is the ability to report the matter to the social-media platform’s “report this” option where it draws the behaviour to the attention of the platform’s administrators.

In the case of forums, blogs or wikis, you should contact the site owner or administrator through the contact options that exist on the site. There will usually be a “Contact Us” link somewhere on the forum, usually on the login screen.

The only situation that can be difficult is a Website that is hastily built up to pillory another person. It may be difficult to track down the owner of the domain name if the domain name isn’t an obvious hosting domain like wordpress.com associated with a particular Web host. Here, you may have to do “whois” searches oh the domain and locate the entity owning the domain. In the case of a subdomain of a hosting domain, you may have to go the the “www” site of that hosting domain to track down who is operating the site.

Aggrieved people should also be aware of local support services especially where there is a risk of depression being brought on by this activity. Some of these services focus particularly on the cyber-bullying menace and provide online or telephone-based advice.  Of course, your friends or family whom you trust can help out with these situations.

Product Review–Brother HL-6180DW monochrome laser printer

Introduction

I am reviewing the Brother HL-6180DW monochrome laser printer which is Brother’s latest entry in to the “office workhorse” laser-printer market.

The printer that I am reviewing here is the top-of-the-line model which has a page throughput of 48 pages per minute, a high-capacity paper tray and wireless networking. There are cheaper variants that have a lesser-capacity paper tray and work more slowly, with the models in this group having different connectivity options having wireless networking, Ethernet networking only or USB direct-connect only. All of them are driven by the same heavy-duty monochrome laser print engine and can print on both sides of the page.

The printer itself

The Brother HL-6180DW is able to connect to a wired Ethernet or 802.11g/n Wi-Fi wireless network. For that matter, it can support Wi-Fi Direct where it effectively becomes its own access point as well as AirPrint driver-free printing for the iOS platform. It still works with Brother’s iPrint&Scan Android app, being able to print Web pages, PDFs and photos from Android or iOS devices. It is also future-proof by being equipped for IPv6 in a dual-stack manner.

As a monochrome laser printer, this printer and the rest of the series are pitched as a “heavy-duty” take of the HL-2240D and similar units that I previously reviewed. These used a separately-replaceable toner and drum setup with the toner cartridge being “nested” in the drum unit that is loaded in to the front of the printer. This still has the advantage of the drum unit being separately replaceable which is more relevant to equipment that is expected to do a lot of work.

But the difference between these units and the other compact units is that the print engines on these models are optimised for heavy-duty printing. Here, you notice the difference with behaviour like the printer sounding like it is doing a normal print run even when working on both sides of the paper.

Printer setup experience

Hardware setup

Brother HL-6180DN laser printer control panel detail

Control panel

Something that can confuse some users is the front-door latch being confusingly part of the output retainer tab. This may be of concern when you are setting up the printer and removing all the packaging material or if you have to ask someone who isn’t familiar with the machine to change the toner or rectify a paper jam.

But once I opened the machine’s front service door, it didn’t take long to get the printer up and ready for use. The drum unit, with the toner cartridge. dropped in to the slot without any risk of user confusion, The paper was also easy to load up with a drawer that didn’t feel tacky.

Software setup

As is my practice when reviewing printers, I install the latest driver set from the manufacturer’s Web site rather than working from the CD that came with the equipment. This is to be sure I am not running a driver set that has bugs or isn’t tuned for best performance with current needs because of the desire amongst manufacturers to get the product to market very quickly.

During the installation phase, the driver software discovered the printer very quickly and was able to have the printer ready to go within a few minutes. Like other driver programs used with Brother printers, it still has the same easy-to-use user interface where there is a list of selected options for the print job.

Printer useability and page quality

The Brother HL-6180DW laser printer doesn’t take long to start turning out the print jobs. Here, it took only a second from when I clicked the “Print” button on the computer for it to come to life and have the first page of the document coming out of the output bay. There wasn’t any unnecessary curling or buckling with the paper after a print run because the printer’s fuser unit was effectively at temperature when the job came in. Even the auto-duplex cycle was very quick with it taking around three seconds to print both sides of the page.

There is a confidential-print mode where you can set up a passcode that you enter in to the printer to claim the print job. But, like the other single-function printers with this feature, it requires the user to enter the passcode using the “pick’n’choose” method with the arrow keys and this can cause users to be impatient with this printer.

Brother HL-6180DN laser printer replaceable parts

Separately-replaceable toner cartridge and drum unit that nest in to each other

Like all of the Brother laser printers, the HL-6180DW uses a separately-replaceable toner cartridge and drum unit which slot in to the front of the unit. Here, like the compact HL-2240D and others in that series, this unit requires the drum unit to be removed from the printer before you can replace the toner cartridge. But it is still easy to detach and attach the toner cartridge and drum unit by you pressing a distinct green tab to separate these pieces.

The auto-duplex function was exact with the registration when printing A4. This would be important for desktop publishing, especially if you want to turn out tent cards, door hangers and the like.

When you print colour photos using this printer, the 1200dpi image was brighter than the 600dpi image, thus was also close to what a colour image would look like on those old black-and-white TVs. The printer also turned out some very sharp text from material printed out from the computer.

The Brother HL-6180 laser printer was very reliable with turning out a large auto-duplex print job, thus not being prone to jam up. In fact if it runs out of paper, you don’t need to do anything further to get the job going beyond just putting the paper in the drawer.

Limitations and Points Of Improvement

The Brother HL-6180DW and others in this series could benefit from a few useability improvements here. For example, a distinctly-coloured latch release for the front service door could be beneficial here because this is hard to find amongst the document retainer flap on the top of the printer. Here, the confusion can occur if a user had to open up the printer to replace the toner or rectify a paper jam.

As well, there is the absence of a “fuel-gauge” on the display to show how much toner is available. Here, this can be useful if you were to determine whether to always run high-capacity cartridges or know if you were to order extra toner after a large print job.

Similarly the printer could benefit from a USB port to permit walk-up printing of PDF files or use of a USB keypad to improve the useability of the printer’s “secure print” function. This could be delivered as a product differentiator for the high-end models. As well, the HL-5470DW could be able to work with the extra-high-capacity toner cartridge, which could be handy if you were to avoid having to spend heaps of money on toner.

As well, the end-of-job cool-down noise could be reduced by, perhaps, gradually slowing down the fan’s speed through the cooling cycle or running the fan very fast for a few minutes just at the end of a print job.

Conclusion and Placement Notes

The Brother HL-6180DW laser printer is one I would recommend for use as an office’s main laser printer. This would be very important in paper-intense environments like schools or medical and legal practices or for those of us who are doing plenty of monochrome desktop publishing. If you could afford to, you may be at a point where you can use the high-capacity or extra-high-capacity toner cartridges for most of the machine’s working life and use the standard-capacity toner cartridge as a short-term measure if the organisation was short on cash.

If you want to save money but want a heavy-duty laser printer, I would recommend that you could go for the Brother HL-5470DW if you value Wi-Fi connectivity or the HL-5450DN if you are just connecting to an Ethernet or HomePlug network segment. Here, you don’t have the ability to load up a large quantity of paper or use the extra-capacity toner cartridge. But, as I have said before, I would recommend using the high-capacity toner cartridges due to the low cost-per-page and the long time between replacing them.

Technology

Mobile Computing platforms

Lenovo ThinkPad Tablet with stylus

Lenovo ThinkPad Tablet – fit for business

The Android mobile computing platform has, over the past year, become an increasingly-credible platform that overtakes the Apple iOS mobile computing platform. This has been exemplified through the Samsung Galaxy S3 smartphone, the Samsung Galaxy Note phone-tablet bridge device and the Google Nexus 7 tablet. This has even had apple take Samsung to court concerning “trade dress” and similar patents that Samsung copied in their earlier Galaxy S and SII products.

Regular computing platforms

Another set of major technology changes over the past year had come about in the form of new versions of the Windows and MacOS X regular-computer operating systems. These versions, known as Windows 8 and MacOS X Mountain Lion respectively, have introduced various mobile-computing concepts such as touch-driven operation and the app store to the regular computer.

The long-lasting battery can allow the Fujitsu to work well for a long day of hotspot surfing at inner-city cafes and bars

As for the hardware, Intel had launched the third-generation “Ivy Bridge” classic-instruction-set processors with improved integrated graphics. This has raised the stakes for regular-computer graphics especially in the portable-use arena.

Bluetooth Smart Ready

The Bluetooth standard now embraces the 4.0 “low-power” variant which supports sensor and control devices that can work on 2 AA batteries or a watch battery for something like six months. This requires that the sensor devices work with a host device that implements Bluetooth 4.0; and this feature is slowly creeping in to all of the credible smartphones and tablets as well as some regular computers like Apple’s latest MacBook lineup and some of the Windows-based computers.

Awareness of malware targeted at the Macintosh platform

It is also the era that the Apple Macintosh platform is gain a similar user base to the Windows platform as far as regular computing is concerned. It doesn’t matter whether the core task for that computer is to be office work or creative work like media editing or playback, with some Windows computers being used for the latter purpose.

This has drawn malware creators to the idea of using the Macintosh platform as an attack vector, mainly through the use of cross-platform runtime environments like Java or Adobe Flash. This is due to the ability to quickly write and deploy the same version of software to run on both Windows and MacOS, with the runtime module liaising with the file system and other operating-system services/ Lately this vector has been taken further with zero-day attacks because the Java runtime isn’t updated as quickly and as regularly as the native-code software for the main regular-computing platforms.

We are being encouraged not to implement these runtime platforms unless necessary and I have raised the idea of compiling Java-written code to platform-native logic when writing for a regular-computing platform rather than creating intermediate code that requires the runtime component. This is so one doesn’t have to run a Java runtime component which can be used as an attack vector or allow a slow operating environment. Similarly, there will be a requirement by Symantec and others to write “security runtimes” that check for malware in Adobe Flash or Java intermediate code.

Network technology

802.11ac wireless networking

As for the small network, there have been a few trends concerning it. For example, a pre-release version of 802.11ac Gigabit wireless networking has been released but this is intended to work on the 5GHz radio spectrum.

Wi-Fi Direct wireless-network setup

Similarly, we have become more aware of the Wi-Fi Direct wireless-network setup concept. This is more about creating a Wi-Fi “personal-area network” either as an alternative to Bluetooth for wirelessly connecting peripherals to a host computer or setting up a temporary “on-the-road” network for mobile devices, laptops and network-connected peripheral devices.

I had reviewed a device which was an example of this concept in the form of the Kingston Wi-Drive, one of the “wireless portable storage servers” that are being promoted for use with smartphones and tablets. Another class of device that is exemplifying this concept is some of the recent crop of network speaker systems that can play music from a computer device via a Wi-Fi network that it is part of or can create itself. They use either Apple AirPlay or the open-frame DLNA standards to transfer the audio content from the computing device to the speakers.

HomePlug AV 500

Another trend for “no-new-wires” networking is the use of HomePlug AV 500 which is a high-throughput variant of the HomePlug AV powerline network. This will have the same situations as the HomePlug 1.0 Turbo network where all the endpoint devices that exist on that segment have to he the high-speed variant for the segment to work at the high bandwidth.

WPS in a multi-access-point wireless network

A question I have answered myself in the course of troubleshooting and optimising a home network was how the WPS easy-setup solution would cope with a multi-access-point wireless network. These kind of network setups are often required where there are building setups that could impede radio-wave transmission, such as interior walls made of double-brick, stone, reinforced concrete or the existence of metal walls.

The above-mentioned networks would have two or more access points which are linked to each other via an Ethernet or HomePlug AV wired backbone. All the access points operating on the same band are set to the same SSID and security parameters but are set to different radio channels so that the wireless client devices can roam between the access points seamlessly.

Here, I found that as long as the access points that have this feature are set up to persist their current setting when you engage the WPS push-button setup function, this function won’t affect the proper operation of this extended service set. What’s more, you can use this quick-setup routine at the access point closest to where you are intending to use the new device you are setting up.

Milestones

Two milestones have happened over the past year. One was the death of Steve Jobs who. along with Steve Wozniak, founded Apple in the mid 1970s. This led to the arrival of one of the first credible personal computers in the form of the Apple II, the commercialisation of the graphic user interface with the Macintosh and eventually a credible mobile computing platform with the iPhone and iPad. When I heard that Steve Jobs was falling ill with the cancer, I saw it in a similar light to Bill Gates leaving Microsoft – the foundation stones of personal computing coming away.

Another milestone that was celebrated this year during the Opening Ceremony of the 2012 London Olympics was Sir Tim Berners-Lee. Her was the founder of the World Wide Web and, effectively, the Internet as we know it today.

This site

I have increased the quantity of Ultrabooks and similar computers reviewed on this site, focusing on them being secondary travel computers rather than main or sole computers. I have also revised the laptop buyers’ guide to encompass this class of computer.

Similarly I am increasing the amount of coverage dedicated to the online lifestyle. With this, I have given special coverage to the sports scoreboard apps that you can download to your smartphone or tablet so these devices can become sports scoreboards. I have tied it in with some of the main sporting events.

As well, part of giving some more time to travel and lifestyle is to establish a “travel and lifestyle” page which will have useful information for travellers and for people who integrate their IT in to their lifestyle.

My post on the Australian Audio & AV Show 2011 has allowed me to sum up the trend towards network-driven audio and video, especially as it is being considered of respect at the top end of the market. This has intensified my interest in the DLNA-compliant home media network because of it being respected by hi-fi manufacturers of respect.

I have spent some time writing some advisory  articles on common computer-usage topics. One of these was a two-part “Email Essentials” series (1, 2) where I explained about basic email-usage concepts, something I have often had to help people who aren’t competent with computers on. I augmented this with another article about using email for sending messages to be “taken further”, which was targeted at people who regularly use Facebook, Skype, iMessage, SMS and other messaging systems.

These two articles are based on work that I have done whenever people ask me for assistance with their computers. I have also written up an article about dealing with that “hair-trigger” mouse which can happen with different mice and as they get used more.

As well, I have written an article on how to keep your computing skills alive and relevant when you retire from active work life. This encompasses what computer system to use as your main computer setup, including the idea of buying out your laptop or desktop that you have used at your work; as well as keeping the skills alive.

Because I have reviewed some business-grade laptop computers and other computer targeted at the business user, I have written an article about this class of equipment becoming relevant to the small-business and SOHO user. Typically, the distributors tend to pitch this class of equipment at the “big end of town” i.e. the larger corporations who have a large fleet of these computers, and these products are not made easily available to the smaller operator even though they can do the job as well for them.

I had written up an article about setting up for Internet when you move to a location in France. This is due to the highly-competitive Internet and triple-play market that exists in that country and I have encompassed some coverage about the Freebox Révolution Internet gateway and set-top box as being an example of what is being offered as carrier-provided equipment in France.

I have given a fair bit of coverage to the cloud-computing trend especially as this is frequently referenced in the computing press and bandied about by people selling IT solutions to small business. This was instigated by an interview that I did with — regarding secure computing in the cloud-computing age and had written an article about what small business needs to look for when they sign on to this kind of service.

I have given some coverage to the issue of device firmware updates and field-delivered software to computing devices. This is in response to legal action that was taking place in the US concerning the device firmware updates that were being applied to HP printers. This legal action was raising the possibility of loading modified firmware in to a device that could facilitate espionage or other undesirable activities. Here, I was describing the trends that occurred with the firmware-update practice over the years and raised security and updating issues concerning this practice, and the fact that the firmware-update ecosystem must deliver a secure update for the device and when we deliver the first update for a device, we deliver one that brings it to expected functionality once and for all.

Conclusion

Expect a very interesting next year for regular and mobile computing life as Windows 8 and MacOS X Mountain Lion merge the context of mobile and regular computing with different devices suiting different needs occupying particular spaces in the home and small business network.

Buyer’s Guide–Headphones and earphones

A situation that may easily come your way is that you may need to purchase a set of headphones for use with your MP3 player, smartphone or laptop. Similarly, a pair of headphones may come in handy as a gift idea for most people who travel or use the mobile or portable computing and audio equipment a lot.

Headphone acoustic-design types

Headphone driver-positioning arrangements:

Intra-aural: This type has the speaker driver placed within or on the ear canal and is typically represented by the classic hearing aid or the common earphones supplied with most personal-audio equipment. Some intra-aural headphones use a hard U-shaped headband that hangs around your neck, similar to the cheap “pneumatic” headsets that used to be used for airline inflight entertainment.

Circum-aural: The speaker driver in this kind of headphone sits outside the ear but has the ear enclosed with a sound-proof foam ring wrapped in vinyl or leather. This type is commonly used with aviation headsets and with headphones until the late 1970s.

Bang & Olufsen Form 2 headphones

Bang & Olufsen Form 2 headphones – An example of a premium supra-aural headphone design

Supra-aural: With this type of headphones, the speaker driver is wrapped in foam and is intended to just sit on the ear.

Headphone enclosure or housing types:

A pair of headphones that uses a circum-aural or supra-aural driver positioning arrangement can either have a closed-back or open-back housing.

Closed back: This type does not have any perforation or venting on the drivers’ housings. It is known to provide a focused sound with less sound leakage and improved bass response.

Open back: Here, the enclosure is vented or perforated or the headphones are designed as if the driver mounted freely on the bracket that is attached to the headband or ear clip. These typically can yield an accurate sound with good drivers but cannot be heard easily in noisy environments and can suffer sound leakage where other can hear the content.

Headphone Styles

There are three common styles of headphones that you can choose from.

Earphones

Earphones typically describe the class which plug in to or clip on your ears and don’t have any headband of any sort. Earlier versions used to plug in to your ears like a set of earplugs or a hearing aid, but these evolved over time. For example, Sony ran a set of earphones which were a supra-aural type that had the speaker sit on your ear and they clipped on like the arms of a pair of glasses.  But most of today’s earphones typically have a small speaker that just faces in your ear with the unit resting in your ear.

Traditional headphones

Voyetra Turtle Beach M3 gaming headset

Voyetra Turtle Beach M3 gaming headset – an example of a circum-aural-style headphones

Then you have traditional headphones with a headband that sits over your head. This style has existed ever since this class of device was invented and most of the good-quality heavier-design closed-back types typically used a padded headband.

Compare this with lightweight supra-aural designs like the types that were popular when the Walkman came on the scene. These typically had either a lightweight aluminium or plastic strip serving as the headband with their earpieces anchored on to plastic brackets.

Street-style headphones

Another style that has started to appear in the late 90s is the “street-style”  where the headband wraps around the back of your head and the set rests on your ears in a similar vain to a pair of glasses.

Other points of interest

Headsets

A headset describes any class of headphones that have a microphone either on the cord or as a boom that is attached to one of the headphone housings. Denon has integrated the microphone in to one of the earcaps in some of their headset designs rather than using a separate microphone on a boom or the headset cord, a trend which is now being followed with Bluetooth headsets.

These are used for communications applications like smartphones, forum chatter in online games, business call-centre telephony or Skype / VoIP telephony. They are also being considered useful with voice-activated assistant software of the Siri, Google Now and Cortana kind that is becoming part of desktop and mobile computing.

Wired headsets typically have a four-conductor 3.5mm plug which may work with some devices like laptops or iPhones but may not work with other devices. These may also come with a breakout cable to plug in to a microphone jack and a headphone jack.

Noise-cancelling headphones

Most manufactures are selling a range of “Active Noise Cancelling” headphones that are pitched for travel use. Here, these headphones, typically traditional closed-back circum-aural types, use battery-operated circuitry that feeds a form of “anti-noise” to combat the low-frequency noise that you hear when in a plane, train or bus.

You are still able to hear voices from around you such as announcements that come over the vehicle’s or aircraft’s emergency-announcement system and these headphones can play program material coming from any audio device that you connect to them. In some cases and with some of these headsets, you may find that the noise-cancelling functionality may allow you to easily hear any background music or radio program being played through the vehicle’s or aircraft’s announcement system. This is because the active-noise-cancelling setup effectively “pushes aside” that loud droning noise of the vehicle or aircraft. Here, you have the ability to hear the program material in relative peace and quiet without the drone of the vehicle’s or aircraft’s engines distracting you.

It is worth paying attention that Bose, Sony and Bang & Olufsen are vying with each other to front up with the best active-noise-cancelling Bluetooth headsets in the form of the Bose QuietComfort 35 Series II, the Sony WH-1000XM3 and the B&O Beoplay H9i. Sony was pitching the ‘XM3 headset as a value-priced answer to the Bose QuietComfort 35 II while B&O came up with the H9i to compete in the brand-driven premium scene with an European answer to the Bose. Bose subsequently offered the Noise Canceling Headphones 700 as their modern-look follow-on to the QC 35 II. Here, this will show that the active-noise-cancelling Bluetooth headset is a very keen product class that is being marketed on both value and quality.

In the case of in-ear noise-cancelling headsets, Apple and Sony are competing with each other by the former offering the Apple AirPods Pro and the latter offering the Sony WF-1000XM3. Here, Sony is working to achieve the same kind of performance as the AirPods Pro but working at a value-for-money price like they did with the WH-1000XM3 headphones.

Wireless headphones

JBL E45BT Bluetooth headset

Some manufacturers supply wireless headphones that use an infrared or radio link from the audio source to the headphones.

There are some of these headphones that require that they work with a manufacturer-supplied transmitter that connects to the audio source. It may allow for special functions like headphone surround-sound or as a cost-saving measure for very cheap setups. These are more applicable if you intend to use them with a regular TV or music system rather than a computer or mobile device.

On the other hand, most of these headphones and headsets work using Bluetooth standards. This is in order for them to work with your mobile phone as a hands-free communication device and for entertainment in the case of smartphones. But they can work with regular computers running Windows 7 or MacOS X Snow Leopard and newer versions of these operating systems for communications or entertainment. Or they can work with a Bluetooth transmitter like the AirFly for a wireless link to existing audio equipment. As far as traditional desktop computers that don’t have integrated Bluetooth go, you may need to use a Bluetooth dongle to bring this wireless functionality to these computers.

If you do buy Bluetooth headphones, make sure that they comply to Headset Profile, Hands-Free Profile for headsets that have a microphone; and, in the case of those that have stereo headphones, A2DP audio profile. If the headphones or headset implements a form of media control, they should implement it to the AVRCP profile.

A feature that an increasing number of Bluetooth headsets is offering is multipoint functionality. This allows a single headset to work with two devices at the same time. It has come about due to people using a laptop or tablet and a smartphone at the same time or using two smartphones like a work/business phone and a private phone. Simplified setups like what JBL offers allow a call from either device to be managed through the headset’s controls without any procedures or allow you to simply start a content source on either device without any extra fiddling.

Increasingly most of the headphone manufacturers are offering in-ear earphones that have full Bluetooth wireless-headset functionality with some of these being described as “true wireless” earphones due to there not being a cord to link each earphone. These have their own batteries but use a supplied case with an integrated charger that runs from its own battery to charge these earphones. It has been brought about through the use of newer Bluetooth standards which allows for ultra-compact battery-powered Bluetooth devices.

Bluetooth earmuffs

A significant number of manufacturers are offering Bluetooth earmuffs which combine an occupational-health-and-safety compliant pair of hearing-protection earmuffs with a Bluetooth headset. They are pitched for people working with loud machinery or in similar situations and need to protect their hearing from the noise associated with these situations.

Better designed units will have circuitry to enhance the inbound and outbound audio for improved clarity and intelligibility.  This may allow you to talk with your caller or hear your audio content without the machine’s noise drowning it out.

Gaming headsets

As part of the core-gamer culture, some gaming-technology and headphone manufacturers are offering headphones and headsets that are optimised for use during video games. These will play the sound-effects during the video game through the headphones and the headset varieties will have the ability to work as a communications headset that is important with online games that offer inter-player voice-chat functionality.

They are less likely to be Bluetooth headsets and will use technologies like a USB digital-audio technology or simply wired-headset technologies. This is to assure that players have the appropriate latency for their games’s sound effects as Bluetooth currently doesn’t have the proper latency required for instant response.

The sound quality that gaming headsets provide will be optimised for the game sound-effects and music with the all-important bass response. These will even be circum-aural, if not supra-aural in order to allow the players to focus on any audio clues that the game yields.

Questions

Do you need to have two or three pairs of headphones “on the go”?

You may think it is unnecessary to have more than one set of headphones in your possession and ready to use. But this may be an advantage where you want to have a particular set of headphones suited to a particular kind of audio content or listening environment.

For example, you may use a pair of earphones or circum-aural headphones for listening in a noisy environment or to hear the detail in a piece of music whereas you may use a pair of lightweight supra-aural headphones when you go jogging so you can hear the traffic. You may even find that supra-aural or circum-aural headphones can suit long listening sessions much better than in-ear earphones, which may be of concern if you frequently use your headphones as a communications headset.

What kind of headphones suit your needs best?

If you are doing a lot of walking, you could benefit from a good-quality set of lightweight supra-aural headphones because they are not tiring to wear and you can still be aware of the traffic and other sounds around you.

A pair of closed-back circum-aural headphones, perhaps equipped with active noise cancelling can come in handy if you use public transport, especially planes, buses, diesel-powered trains or underground trains (subways) frequently. This can cut out the droning noise associated with these public-transport options and let you focus on your programme material.

Similarly a DJ or someone who likes to do a lot of recording could benefit from a good-quality pair of circum-aural headphones. Some of these headphones that are targeted at this application may be described as “monitor” headphones because you are after the high-quality sound that you want to use as a reference while not hearing outside noises or allowing sound to leak out thus causing a feedback loop with a public-address or broadcast application.

When you want to hear an accurate sound while listening to music or other content especailly when alone, you could benefit from a good-quality pair of supra-aural headphones that have large drivers like the Sennheiser range. This may be of importance with classical-type music, some kinds of jazz music or a lot of the down-tempo music classes like easy-listening / lounge or ambient / chillout music.

On the other hand, closed-back headphones can yield improved bass response which is important for popular up-tempo music, especially jazz, funk / soul, dance music or rock.They can also be handy if you want a distinct weighty impact from sound effects in video or games content.

What to look for with headphones

Things to look for to see long service life

When you buy a set of any headphones that you use a lot, make sure that you can purchase replaceable earpads or foam rings for the headphones. This is important that as you use a set of headphones, the earpads or foam rings do tend to tear or come apart over the years of use and you still want to have your headphones comfortable to wear.

Headphones that have a “single-sided” cord have an advantage because the cord comes in to only one housing with the other housing being serviced by a cable that passes through the headband. This cuts down on cable entanglement and can avoid the situation where you could ruin one earpiece due to the cable being tugged on that earpiece.

Some premium headphones do have the cord detachable from the earphone housing. The advantage here is that you can replace the cord if it gets damaged, which is something that can easily happen as you use the headphones out and about.

Conclusion

When you choose the right sets of headphones for your private-listening or communications needs, you will be in a better position to enjoy them better in the application you have bought them for.

Product Review–Voyetra Turtle Beach M3 Gaming Headset

Introduction

I haven’t reviewed any headphones or headsets for this site in a long time but had bought the Voyetra Turtle Beach M3 gaming headset as a “ring-in” when I left my headphones behind before heading out. Here, I thought that it would be an opportunity to review this headset and assess its prowess as a computer accessory for gaming, laptop and mobile use.

This is a headset that has an in-line microphone for use with smartphones and tablets using a four-conductor 3.5mm plug; or can be connected to a computer or other device using a break-out cable that plugs in to the headphones and microphone jack on the device.

Price

I had purchased this headset from EB Games for AUD$48.

Type

Headphone Assembly Traditional over-the-head
Driver Positioning Circum-aural
Driver Enclosure Closed-back
Microphone Position In-line
Connectivity
Headset 3.5mm four-conductor plug
Adaptors Breakout cable to:
3.5mm stereo headphone plug and 3.5mm microphone plug

 

The headset itself

Connectivity

As far as connectivity goes, the Turtle Beach M3 headset doesn’t work well as a headset with my Samsung Galaxy S Android phone and I had to use the jack adaptor to run the headset as headphones. It may work well with iPhones and does work well with laptops that have 3.5mm audio I/O jack like the Dell XPS 13 Ultrabook that I am reviewing.

In-line microphone rather than a boom microphone

The headset uses a single-sided cable that has an advantage of being less likely to have the sound cut off to one earpiece due to a cord being pulled out. It also has the advantage of having the cord easier to manage as you use or store the headphones.

Comfort

The Turtle Beach headset’s vinyl earcups do feel sweaty after a significant amount of time wearing them and the headset does feel tight and less likely to slip off your head.

The earcups appear to be supra-aural due to a speaker grille flat across the front but work like the circum-aural design. They also sit effectively on the ear rather than wrap around the ear

Sound

One key factor I have noticed with the Turtle Beach M3 headset is that they shine on bass response. This does come through with some recently-recorded funk and soul music where the bass line comes out clear.

As for games and movies with the sound effects, the headset does perform with them. The Turtle Beach headset has shone with the effects at the start of “Kurt Wallander: The Sniper” which I was watching as on-demand video using a review-sample laptop. This is where there was some gunfire from the sniper’s weapon followed by the snarl of a “scrambler” motorcycle’s engine as the sniper escaped. The gunfire had the full “punch” and you could hear the bike’s engine’s distinctive noise was as if you were near one of those trail-bikes.

Here, this represented the kind of effects that are often encountered in video games with the gunfire being part of “shooter” and warfare games; and the motorcycle engine noise being part of what would be heard in racing games.

But I have noticed at times that the higher frequencies can sound a bit coloured without any distinct clarity. This can cause some fatiguing after a while of listening.

I have used the Turtle Beach M3 headset with my phone on a bus, mainly to test for its useability on transport environments. The headset had reduced the engine noise significantly in a way that I was able to distinctly hear the music on my phone easily. This would make it work well when travelling on buses and diesel railcars and may be of use when flying. Even telecommunications voices have come through very clearly as I was able to use the headset as headphones using the break-out adaptor and the phone was running Android 2.3 Gingerbriead and allowing me to use its microphone to speak to the caller.

Conclusion

Voyetra Turtle Beach M3 gaming headsetI would recommend that one purchases the Voyetra Turtle Beach M3 gaming headsets primarily for gaming or watching video content in a relatively noisy environment such as while travelling on public transport. For music, you could use this headset when listening to popular music where it is critical to hear that bass-line, again especially in a noisy environment. If you intend to buy them for use as a headset for your smartphone, make sure you can try them out with the phone before you buy them.

Could an upgrade to Windows 8 yield a performance boost to your computer

Article

Installing Windows 8 on your old PC could turn it into Greased Lightning | ZDNet

My Comments

Some of us might think about upgrading an existing computer system to Windows 8 when this operating system is released rather than staying with Windows 7. Most commonly, there would be a lot of doubt about this process but, in some cases, it could improve the computer’s performance.

A Windows computer that was built up in the last four years i.e. since Windows Vista was launched could easily benefit from an upgrade to Windows 8. This is due to the reworked code that is written to work best with the recent generation of hardware.

The speed increase also comes due to natively-integrated desktop security software as well as Internet Explorer 10 and integrated cloud-computing support.

But I would recommend that the system which is being upgraded has current expectations for RAM and secondary-storage capacity. This would be 4Gb RAM and 128Gb of secondary storage as a bare minimum. If the machine uses a hard disk rather than solid-state storage, I would expect it to have at least 320Gb. As I subsequently mention, the operating system is at a price point that may allow you to budget in a hardware upgrade to these expectations.

Users can upgrade their Windows computers to the new operating system at a cost-effective price due mainly to the “electronic hard-copy” distribution that Microsoft is using i.e. to buy and download the operating system online rather than having to buy a packaged copy with an optical disk. This is in a similar way to how Apple are distributing the MacOS X Lion and Mountain Lion operating-system upgrades. It also comes with some attractive licensing terms including the ability for those of us who are building our own systems to legitimately purchase a “system builder” package.

It would be OK to go ahead with the upgrade if you can handle the changes to how the operating environment works, such as the new touch-focused Start “dashboard” and having to “descend further” to get to the standard operating interface. But I would recommend that those of us who aren’t computer-competent should stay with Windows 7 unless they are buying a new computer that comes with Windows 8.

Wi-Fi Alliance starts certifying tunnel technology for better wireless performance – PC World Australia

WiFi alliance begins Tunneled Direct Link Setup certification, hopes to improve media streaming | Engadget

My Comments

The Wi-Fi Alliance have released a new certification standard for allowing better wireless performance amongst devices in a wireless-network segment. This standard, known as Tunnelled Direct Link Setup, allows devices that are authenticated with the same access point to transmit data directly to each other.

Allowing direct node-to-node connection after an access point establishes the connection to allow for faster data-transfer performance between clients on a Wi-Fi segment. This would also yield an improved quality-of-service for media streaming or improved latency for real-time gaming.

Not like Wi-Fi Direct where a device that is normally a Wi-Fi client is there to facilitate a network connection. This is more about establishing a direct best-case device-to-device connection rather than a via-access-point connection for a file transfer or media-stream method as a way of improving the data-transfer performance.

When a TDLS link is set up, the devices would form this link at the best abilities available to each other, such as higher speed, quality-of-service, power-saving practices or security compared to what the segment’s access point would offer. Similarly, the access point does not need to be upgraded for this functionality to take place.

The access point would still play its role if the client devices move further afield, thus repeating the data between the client devices. Similarly it would also fulfil network-bridging tasks such as linking to the wired backbone or the Internet service in the case of a Wi-Fi router.

This functionality would be part of newer Wi-Fi-network chipsets that would be deployed in newer computers and similar devices. It would be interesting to see how it works further once more TDLS-enabled devices are in the field.

New Zealand to get fibre-to-the-premises network

Article

FTTH the right choice: NZ IT minister | ZDNet

My Comments

Australia, France and a few other countries are implementing fibre-to-the-premises technology as their mainstay next-generation broadband networks. Similarly, some local “real-broadband enablement” deployments in some country towns like Hambleton in the UK have set up for this technology.

Similarly, those countries who have established fibre-copper next-generation broadband services, like the VDSL network in Germany and the fibre-to-the-cabinet deployments in the UK, have shown interest in the FTTP technology in some limited-area or pilot deployments.

Now New Zealand have shown interest in creating a next-generation broadband network. This time, they have headed for the fibre-to-the-premises technology rather than the cheaper fibre-copper technologies. Of course, the rural areas would be serviced with fibre-copper or fixed-wireless setups rather than the all-fibre solution.

The New Zealand Communications Minister, Amy Adams, had gone on record that she stood for the technology. She stood for it because there is better fiscal sense in rolling out this kind of network because of it being future-proof, rather than retrofitting the fibre-copper network to an all-fibre setup at a later stage in the network’s service life. This was raised as part of discussions with the Australian Communications Minister, Stephen Conroy regarding trans-Tasman communications, including capping the cost of mobile-phone roaming between Australia and New Zealand.

The country may also have other requirements that are particular of multi-island nations. Here, it would need to benefit from higher-bandwidth

But, in my honest opinion, that country does need to improve on competitive Internet access. It is because I have heard that the New-Zealand broadband services are more expensive compared to Australia and other main Internet markets. The problem is more so with international access streams ran by other operators so that the retain ISPs there can buy cheaper bandwidth and onsell it to the New-Zealand public.
