Product Review- JBL Synchros E30 headphones

Introduction

JBL is best known over a long time for loudspeaker systems, especially PA/commercial-audio and hi-fi speakers. Examples of these speakers include the JBL hi-fi speakers that were designed the same way as in-studio monitor speakers and known for their tight bass response; and the JBL EON speakers which were one of the first active-design PA / sound-reinforcement speakers to use biamplification in that class of speaker.

But as for headphones, they haven’t been known much for this product class. This is because brands like AKG, Audio Technica and Sennheiser have dominated this product class when it comes to good hi-fi or monitor-grade headphones.

Now I am reviewing the JBL Synchros E30 headphones which are positioned more or less as “all-round” stereo headphones for personal-audio applications. These are a headset with an in-line microphone designed for use with your smartphone or tablet or as headphones for use with your MP3 player or laptop.

JBL also offers the Synchros E40BT headset which is a Bluetooth wireless variant of this on-ear headset which may be handy for those of you who value wireless connectivity with your smartphone, tablet or laptop computer.

Connectivity

JBL Synchros E30 headphones - detachable cable

Detachable cable

Like an increasing number of headphones that are coming on the market, the JBL Synchros E30 is equipped with a detachable headset cable which has an integrated microphone. This will most likely be wired for CTIA (Apple) applications and may not operate properly with OMTP applications.

The advantage of this is that you can repair or replace the cord if it breaks which is something that can easily happen with personal-audio headphones as you use them a lot. As well, you could have one or more headset cords made up for different applications very easily, something that can be done if you or someone you know is handy with a soldering iron.

Comfort

JBL Synchros E30 headphones - earcups

Hinge-style anchor for earcups

The hinge design that JBL uses for the Synchros E30 headphones makes it easier to store the headphones flat but it can take a while to get the headphones to fit properly on your head for best sound response.

The “over-the-ear” earcups have a vinyl ring that doesn’t absorb sweat but is very confusing where headphones that have a similar ring encourage you to have this wrap around your ear.

Once these headphones are adjusted properly, you can wear them for a long time without them being too uncomfortable.

Sound

The JBL Synchros E30 headset has the kind of efficience that you would expect for headphones that are to be used with battery-powered equipment. This means that they can sound loud therefore you may be able to run them on lower volumes to save on battery power.

Music

The JBL Synchros E30 does well on the bass response by being able to “reach down there” but it needs the use of equalisation at the source if you want to bring this out. This may be achieved by implementing a “bass-boost” function or a player that uses tone controls or a graphic equaliser. The high frequencies are still there and come out clear.

Video and games

I have watched some video content with these headphones and the dialogue does come through clearly. The effects may not have the punch unless there is some form of equalisation along the way.

I also tried these headphones with an iPhone that a kid was using to play a motor-racing game and noticed that the sound effects associated with that game came across very sharply. But as I have said with music, there still needs to be some equalisation to bring out the bass which is important for some sound effects like motor-vehicle noise or gunfight.

Communications

I have made and taken a few phone calls and the caller’s voice had come across intelligible and clear. The frequency range that these headphones offer could also make them suitable for HD Voice applications like Skype, Viber and VoLTE so you can hear your callers better.

Noise reduction and handling in noisy environments

I have used these headphones up the back of a transit bus and found that the JBL Synchros E30 headphones do reduce the ambient noise from the bus’s engine somewhat. As well, you can still hear the program content if you run the volume hard on your portable device.

Conclusion

I would recommend that one buys the JBL Synchros E30 as a baseline “all-round” headset for most users whether they listen to music, watch video content, play computer games or use them for online communications. This comes across more where users place emphasis on durability with such features as a detachable cord or a strong hinge design along with a sound that can come across as being “authentic”.

The Commodore Amiga turns 30 creating a turning point for desktop computing

Iconic computer and game system Amiga turns 30 | The Age

Video

Amiga Demos of the late 80s

My Comments

In the late 1980s, Commodore released the Amiga series of computers which brought forward the concept of advanced graphics, video and music to the desktop computer.

These computers had the necessary hardware like the Motorola 68000 series RISC processors and graphics and sound chipsets that were advanced for their day. Initially, there was the Amiga 1000 computer but the popular machines that represented the Amiga platform at its peak were the Amiga 500 and the Amiga 2000.

They could generate high-resolution advanced moving graphics which put them on the platform for CGI animated video. As well, they were capable of turning out music which was either synthesised or sampled and this ability became very important during the “Acid House” era of the late 80s where house, techno and other electronic dance music came on the scene.

For that matter, if you ever seen a Commodore Amiga in action or used one of these computers yourself, you may have dabbled with the “demos”. These were self-running programs that showed a moving-graphics display on the screen set to music, typically electronic dance music of the day. I have linked in a YouTube clip of some of these “demos” so you can see what this computer was about.

The fact that the Amiga was popular in Europe instigated the European game-development scene where a lot of graphic-rich game genres that we take for granted were being exposed courtesy of this computer that, at times, was called the “game machine of all time”. For business applications, the Amiga platform even became the heart of some public-facing computer applications where a graphically-rich user interface was considered important, along with it being used to create computer graphics for film and video content.

This computer demonstrated the concept of a desktop computer being able to serve graphically-rich applications whether it be games, video content or the like and other computer platforms acquired this ability through the 1990s and now serve this purpose.

Product Review–Plantronics Backbeat Pro Bluetooth noise-cancelling headset

Introduction

I am reviewing the Plantronics Backbeat Pro Bluetooth noise-cancelling headset which is my first attempt at reviewing a headset equipped with two key features: Bluetooth wireless connectivity and active noise cancelling.

The former feature links to mobile devices and laptop computers via Bluetooth wireless technology while the latter detects noise associated with transport or fans using microphones and applies a “counter-noise” to this noise through the headset’s speakers. When you listen to program content or take a call, the sound from the external device such as the music or your caller’s voice is mixed in with the aforementioned “counter-noise” so you can hear that sound more clearly.

Connectivity and Usability

I was able to pair the Plantronics BackBeat Pro headset with my Samsung Galaxy Note 4 smartphone very quickly – this supported NFC-based pairing which is currently implemented in Android only. But with devices that don’t support it, you can start the pairing process without needing to hold down a button on the headset.  There is support for multipoint use with a simplified call-handling experience where you just touch one button to answer calls from any phone.

There is a 3.5mm four-conductor headset jack which connects to your device via a supplied cord that is wired for CTIA / Apple setups. This overrides the Bluetooth headset functionality so you can use the Backbeat in an airliner.

It is powered via an integrated rechargeable battery that lasts a long time – you could get a day or more out of the headset’s battery life when you are using it as a Bluetooth headset or as an active-noise-reduction headset with another device.

The controls are easy to discover with a large ring on the right earpiece to adjust the sound volume, a large ring on the left earpiece to move between tracks, a large button on the left earpiece for playing and pausing music and a large button on the right earpiece for handling calls. The power and noise-cancel slide switches are easy to discover and locate with the former on the right earpiece and the latter on the left earpiece.

Connectivity options – USB charging socket and 3.5mm headset input jack (wired for Apple / CTIA)

There is a motion sensor that starts and stops your music device when you put the headphones on and take them off. But this can be very erratic in some situations such as a rough road or rail ride or sometimes even putting them on a table and subsequently picking them up has me find that they start playing too early. A supplied configuration program can be used to adjust this function but I would prefer a hardware switch to enable and disable this function.

Comfort and Durability

The Plantronics Backbeat Pro has the same kind of comfort level expected for most circum-aural headsets and could be worn for a significant amount of time. You could feel that they were there without it feeling as though they are crushing on your head and the padded headband provided that feeling as if they were just there.

Cloth speaker grilles assure comfortable long-time use

The ear surrounds even didn’t come across as something that could end up being sweaty. As well, your ears rest on foam cushioning with cloth lining the earpiece areas so as to allow for increased comfort. Here you even have the sides that each earcup represents written on the cloth lining itself. The only comfort tradeoff you may find with the Plantronics BackBeat Pro and its peers is that due to their hard construction, they may feel uncomfortable to use when you are sleeping if you sleep with your head on your side.

As for build quality, I would expect them to last a long time. This is through the use of durable design practices like thicker plastic and placing a plastic conduit which houses the cabling between the earpieces against an aluminium strip.

Sound

I was able to run the Plantronics Backbeat Pro headset at lower volumes while the sound is still audible which makes for a headset that is designed with efficient drivers. This would then allow for the headset to run on its own batteries for a long time yet be useable.

Music

The music came through loud and clear and with that desirable amount of bass response. I even disabled any equalisation curves in my media player and any in my phone to identify whether the bass response was there without the need for added equalisation and found that these headphones still delivered the punch in the music.

Video and Games

The Plantronics Backbeat Pro has come up trumps with video content in that it was able to yield clear dialogue and give punch to those effects. I was even keeping an ear out for effects like gunshots or vehicle moment while watching Kurt Wallander because they are the kind of effects used in some of the games liked by “core” gamers and they came through with that desirable punch.

Communications use

I have made and taken a few phone calls using the Plantronics Backbeat Pro Bluetooth headset and have noticed that the conversation came through clearly for both myself and the caller. I also tried the headset a few times with Google Now and the voice assistant could parse what I was saying easily. The headset call button worked as expected with the ability to tap twice to call the last number or tap and hold to invoke Google Now or Siri depending on your mobile device.

Noise reduction and handling in noisy environments

I used the Plantronics Backbeat Pro headset in the back of a transit bus and had noticed some level of noise reduction when the bus was at speed and was able to hear my music content more clearly.

Active Noise Cancelling

The Active Noise Cancelling function is available when the headset is switched on and can work either with a wired connection or the Bluetooth connection. Here, you then enable it using a slide switch on the left earpiece and can notice the difference.

Here, the rumbling associated with trains and the like is cancelled out using so-called anti-noise. There was a noticeable difference when I used it on the train in Melbourne’s City Loop because I heard very little of the rumbling associated with through-tunnel train travel but could have my music at a decent volume. The experience was also the same when I used this headset in a few different transit buses and the noise from the engine was significantly reduced. As well the noise-cancelling function had no effect on the BackBeat Pro’s bass response. In some situations, I could hear the destination announcements that were called over the train’s intercom or a radio station played over a rail-replacement charter bus’s sound system more clearly and intelligibly even if I had my music going.

The only problem with using Active Noise Cancelling is that if you want to simply just run that functionality without the headset working with another audio device, you have to plug something in to the 3.5mm jack to override the Bluetooth transceiver. This may be of annoyance for those of you who are trying to sleep on the overnight train or that night flight or use the Active Noise Cancelling to effectively mute out the air-conditioner’s noise while trying to go to sleep..

Limitations

The active noise cancelling function  could be set up to run independent of Bluetooth operation or having the headphone cable plugged in. This could be handy when you are in a noisy environment without needing to deal with a cable that can entangle you. An example of this could be to claw some sleep when you are in the plane or in a motel room where there is a noisy old air-conditioner.

The microUSB charging socket on this headset could be set up to work as a way to connect the headset to a computer and have it serve as a USB audio sound device for that computer. The controls could also be mapped through as USB Human Interface Device controls for multimedia and telephony use. This would earn its keep when you are on the plane and using a laptop which is set up for “flight mode”, or are using the headset with a desktop computer for online communications and gaming, especially as traditional “three-piece” desktop computers don’t necessarily support Bluetooth.

The Plantronics Backbeat Pro could benefit from a hardware switch to enable or disable the sensors that allow it to play or stop the music source if you take the headset off. This can be of importance where the ride is bumpy and this function could be susceptible to false triggering.

As well, the headphone cord could benefit from a switch which selects between OMTP / Apple (CTIA) headset wiring mode. This is because not all mobile phones and communications devices are wired for CTIA (Apple) mode and you may want to make sure that your BackBeat Pro could work with anything your present to.

As for adaptors, the Plantronics Backbeat Pro Bluetooth headset missed out on an inflight-entertainment adaptor which is considered abnormal for a noise-cancelling headset that would be typically used in an aeroplane.

Conclusion

I would recommend the Plantronics BackBeat Pro for those of you who value a Bluetooth noise-cancelling travel headset that excels on usability especially when you use your smartphone as a music player when you are travelling on public transport. As well, it would earn its keep with those of you who aren’t necessarily after the fashionable headset brands but are really after something that does the job.

If you do need to use this headset as an active-noise-reduction headset without the use of any program-source device, you could use a 3.5mm plug which you could purchase from an electronics store and plug this in to the audio jack on the headset.

Product Review–Kingston HyperX Cloud II Gaming Headset

Introduction

Kingston HyperX Cloud II gaming headset - boom removed

The headset with a removable boom

The Kingston HyperX Cloud II Gaming Headset is a traditional-look headset with a detachable boom microphone. Here, this allows you to use it as a pair of stereo headphones or as a “full-on” stereo headset. This includes using it in the plane thanks to an “in-flight-entertainment” two-plug adaptor so it can plug in to your seat’s armrest.

It also comes with a USB sound module so you can use the headset with your computer when playing games and this provides claimed surround-sound abilities as well as supporting the audio input and output required of the headset.

The headset is available with a choice of either red accents or grey accents to suit your style.

Connectivity

The headphones that are part of the Kingston HyperX Cloud II come with a four-conductor 3.5mm phone plug which can work with most smartphones and stereo equipment.

Kingston HyperX Cloud II headset USB adaptor

USB headset adaptor for your regular computer – separately adjustable input and output levels

But Kingston provided a USB-connected sound module that presents to Windows as a logical sound-output device and a logical sound-input device. This is done using the class drivers that were provided out of the box with Microsoft Windows and is something you would experience with your Macintosh or your Linux computer. This works properly and is more to allow you to have a separate communications channel for games while you have the sound effects coming through the computer’s speakers.

For Windows users, it is worth reading an article I have written about how you can manage multiple sound devices like headsets especially if you want this to be a private-listening or communications headset.

Comfort

The Kingston HyperX Cloud II Gaming Headset does feel securely tight on your head and is comfortable to wear. This is thanks to the padded headband and the ear cushions which also don’t feel sweaty.

This means that you can enjoy wearing the headset for a long time without any fatiguing even on hotter days or intense gaming sessions.

Sound quality

Music

As far as the bass response is concerned, it is there but not overpowering. It doesn’t overpower the vocals nor does it overpower melodic or harmonic instruments in the mix. Here, this means that you still have that “kick” that is desireable for a lot of music but it doesn’t boom.

Video content

I watched some video-on-demand content using a review-sample laptop and have found that the Kingston HyperX Cloud II gaming headset does treat dialogue and sound effects very well. The headset even handles ambient effects clearly and gives bite to the “sounds that matter” like the aggressive engine sound of a vehicle used in a hit-and-run scene in the show I was watching. This gives it some worth when it comes to using the headphones with your laptop for watching video content or playing games.

Communications use

I have made and taken some calls with this headset and do hear the caller clearly and have used it with the microphone for a video call on my computer. Here, I had to raise the volume on the supplied USB adaptor to get my voice heard by the caller when I was making a Skype call.For portable use, you still need to run the Kingston HyperX Cloud II Gaming Headset hard with some devices to obtain a decent loudness and this may also have an impact on your device’s battery life. With laptops, I could get a decent sound out of the headset without running it at a high level.

Noise reduction and handling in noisy environments

I have used the Kingston HyperX Cloud II gaming headset as a travel headset and integrated a bus journey as part of my travels. Here, I sat up the back of a typical transit bus and used the headset there to determine whether the engine noise was reduced while I used it.Here, I noticed a significant amount of noise reduction while being able to hear the program material that I was listening to and concluded that you can benefit from this somewhat for bus or train travel but may not be effective for air travel especially when the plane is in flight.

Limitations And Points Of Improvement

One feature I would like to see for the Kingston HyperX Cloud II Gaming Headset would be to have a detachable cable and the availability of replacement cables. This is because whenever you are engaging in heavy gaming, you may pull on the headset and this could cause the connection to become unreliable.

Similarly, the USB adaptor could be offered as a standalone accessory for use with headsets so you can connect a headset of your choice with your computer for gaming, videocalls or voice recognition. Here, it could be switched between the Apple configuration or the OMTP configuration so it can be used with headsets destined for the iPhone or open-standards devices. This is something that will be important for the Windows platform as Cortana comes to the Windows 10 operating system as a voice assistant or for businesses who want to use softphones as part of their IP-based telephony needs.I would also like to see the headset plug able to be switched between Apple and OMTP configurations to work with smartphones, along with a switch on the cable or headset for call control.

Conclusion

It is easy to think of the Kingston HyperX Cloud II Gaming Headset as strictly a gamer’s headset but it can work well as an all-round headset you could use with your laptop or your smartphone. This is more so if you are on a budget but you still want some “kick” from your music or sound-effects.

As for value-for-money, I do find that this headset does offer that especially if you want to see it in use beyond your games console or “gaming-rig” computer, such as for Skyping friends, listening to music or watching videos using your tablet or laptop.

Managing multiple sound devices in Windows

A common situation that will face most of us who use Windows or Macintosh regular computers is the issue of dealing with multiple sound-output devices with these computers.

There are examples of this such as:

  • USB speakers with a laptop

    USB-driven hi-fi speakers with a laptop

    Desktop or laptop with regularly-used sound system (integrated speakers, desktop speakers served by installed sound card or integrated sound subsystem)

  • A hi-fi-grade “USB DAC” connected to or integrated in a hi-fi amplifier or home theatre receiver for high-quality sound reproduction.
  • Bluetooth speakers, headsets, and audio adaptors or AV equipment that has Integrated Bluetooth A2DP functionality as I have covered in another article.

    Pure Jongo T6 wireless speaker

    A Bluetooth speaker that could be an extra speaker for a laptop

  • A media hub or “jack pack” in a hotel room that works with a flat-screen TV installed there, or a home theatre receiver or flat-screen TV that is connected to the computer via HDMI or DisplayPort
  • Virtual-sound-card programs like Airfoil or Jamcast that use network-connected devices as a computer’s sound card.
In-room AV connection panel

But you can have problems with these kind of setups. Some programs like Windows Media Player, Skype or some games may allow you to determine the sound-output device they use but you may have to switch the default sound device you are using to suit most programs like Web browsers and Spotify where you can’t determine the sound-output device for the program. A few of the games may allow you to run a headset from a separate sound device for online game chat or voice recognition.

Similarly, a computer’s audio subsystem may have different output or input connections such as a line-out jack or an SP/DIF jack on a good sound card or an integral microphone and an audio-in jack on a laptop’s sound subsystem. These can be listed as separate sound devices depending on the device driver in place.

Bluetooth device listed alongside default audio device

List of audio playback devices in Windows – the one with the green tick is the Default Device

Microsoft Windows from version 7 onwards allows you to determine two “default sound devices”:

  • Default Communications Device, which defines devices you would use for VoIP, video telephony and similar applications
  • Default Device, which covers all sound-output needs including music, video, games and system notifications as well as communications sound.

The idea behind this setup is that you could have a device like a mono Bluetooth headset or not-so-good speakers like your laptop’s speakers being used by a softphone application while a pair of good speakers or a hi-fi system is used for music playback or game sound-effects purposes.

It is feasible to determine a device as being a Default Communications Device or Default Device in the context of recording or sound-capture only. This is achieved in the Recording Devices menu when you right-click on the Speaker icon.

Selecting a Default Device in Windows

Right-click sound menu

Pop-up menu when you right-click on the Speaker icon on the Taskbar

Windows 8 and 8.1 users will need to use the Desktop view rather than the Modern tiled view to select the Default devices.

  1. Right-click on the Speaker icon on the Taskbar
  2. Select Playback Devices
  3. You will see a list of audio output devices on the screen
  4. Right-click the device you intend to use and select Default Device or Default Communications Device depending on your needs.

How do you cope with temporary devices?

A temporary device like a Bluetooth headset or HDMI-connected TV is one you wouldn’t be connecting to your computer all the time.

Here, you make your temporary device the “Default Device” when you start using it. What happens when you disconnect the device, whether logically or physically, is that the computer will fall back to the sound subsystem it last used before you connected the temporary device.

Bluetooth devices

A computer will remember all Bluetooth devices that have been paired with it previously but those that aren’t logically connected to the computer are listed as “disconnected” devices.

If you use a Bluetooth device between multiple source devices, you will have to make sure you disconnect it from the existing source device before you logically connect it to your PC. Some source devices like iOS devices may require you to “unpair” the device rather than logically disconnect it. Then, when you want to use that source device with your Bluetooth device, you have to connect it or pair it again.

Bluetooth headset as two devices

A Bluetooth headset or other device with A2DP and Hands-Free functionality is represented as two devices

A Bluetooth headset, car Bluetooth subsystem or other Bluetooth with A2DP audio playback and hands-free / communications-headset functionality will be listed as two sound devices – a Headset device which represents its communications functionality and a Headphones device which represents its A2DP music-playback functionality. Here, once you have logically connected the headset, you make the Headset device the Default Communications Device if you just intend to use it as a communications headset for VoIP and similar applications. On the other hand, you make the Headphones in that device the Default Device when you want to play music and other audio content in private and this also makes the Headset in the same physical device the Default Communications Device.

Sony devices with NFC have simplified the process of connecting and disconnecting by allowing you to touch the source device to the output device to connect or disconnect them. But this may only work with computers that have the NFC functionality in them.

To connect a previously-paired Bluetooth device in Windows 8.1

Windows 8.1 has introduced a “connect / disconnect” routine to Bluetooth audio devices so you can properly connect and disconnect these devices without having to go through a pair-up routine.

  1. Make sure the device is logically disconnected from your phone or other source devices and is paired to your computer or set up your Bluetooth device to work in Multipoint mode.
  2. Right-click on the Speaker icon in your Desktop
  3. Select “Playback Devices”
  4. Right-click on the device you want to connect
  5. Select “Connect” to connect the device to your system
  6. Once it says “Connected” under the device’s icon, right-click on the device and select “Default Communications Device” or “Default Device” to suit which of your computer’s sound output will come through that device.

To disconnect a previously-paired Bluetooth device in Windows 8.1

  1. Right-click on the Speaker icon in your Desktop
  2. Select “Playback Devices”
  3. Right-click on the Bluetooth device you are currently using
  4. Select “Connect” to disconnect the device from your system

What can be done here?

Allowing a user to class certain devices as “temporary” devices or “permanent” devices.

A common situation that can happen here is the use of temporarily-connected devices like Bluetooth headsets, USB DACs or HDMI connections. Here, a user could class these as “temporary” devices and the computer determines them as default audio or communications devices when they are connected.

But when they are disconnected, the computer falls back to its “permanent” devices such as its integrated speakers or regular desktop speakers.

Other “default sound device” classes for audio-video playback, games or system notifications

It could be easier to implement an application-specific “default sound device” for applications beyond communications. Here, it could be feasible to implement an application class for audio-video playback or gaming so that you could make sure that system notification sounds don’t play through the hi-fi speakers for example but you have Spotify playing through those speakers.

A Tile or Charm on the Modern view for selecting sound output devices.

The Windows 8 Modern view a.k.a. Metro view could benefit with an option directly selectable from that interface for managing the sound devices. This could be in the form of a Modern-View app downloadable from the Windows Store that puts up a dashboard for managing your sound input and output devices.

Product Review–Sony MDR-10RC Stereo Headset

Introduction

I am reviewing the Sony MDR-10RC stereo headset which is a new set of Sony headphones optimised for the kind of audio recording technology that was being put forward for high-quality sound such as the 24-bit 192kHz file-based audio along with the “new-cut” vinyl records.

They are the “compact” base set of headphones for the MDR-10RBT Bluetooth headset and the MDR-10RNC active-noise-cancelling headphones to take on the plane with you. Sony have taken the right steps by designing advanced headset categories based on a good pair of headphones rather than “reinventing the wheel” by designing new headsets for the advanced categories.

Sony MDR-10RC headphones - detached cord

Sony MDR-10RC headphones with cord detached

The Sony MDR-10RC stereo headphones have single-sided connection but they also have a detachable cord which is a feature that I desire of headphones. I remember the countless times that I have had to write off headphones because the cord has become damaged near the equipment plug and the detachable cord means that I can easily repair or replace the headphone cord if it becomes damaged.

Like the previously-reviewed Denon MusicManiac AH-D600 stereo headphones, these headphones come also with a separate “headset cable” with inline microphone which turns it in to a stereo headset as well as a 3.5mm stereo jack cord for use with other equipment.  This can make these headphones earn their keep with smartphones and similar devices when you do a lot of the travelling.

Comfort

For this class of headset, the Sony MDR-10RC felt very lightweight. This, along with the padded headband, made the headphones very comfortable to wear and less fatiguing to use.

The earcups on these headphones don’t feel excessively sweaty thus being able to be worn comfortably for a long time even on hot days.  This is compared with the way some headphones that use leather or vinyl ear surrounds or cushions can feel sweaty after a significant amount of use.

Sound

The Sony MDR-10RC headphones yielded a fair bit of “kick” from the bass but it wasn’t too boomy or dominant. I could also hear the rest of the music clearly and effectively hear a lot more of the quieter parts of that music. It has meant that this pair of headphones could come in to their own if you love your music. As well, the sound wasn’t in any way fatiguing to listen to.

Even for non-music content, the Sony MDR-10RC headphones were able to come through well with this content. Here, you could hear the voices clearly and effects from home video were able to come through clearly without being “muddled”. The bass response had also given life to various voices from YouTube videos I have seen using my phone.

Noise reduction and handling in noisy environments

In the CBD environment, I had noticed a significant amount of noise reduction with some of the essential sounds from outside coming through. As well, I used the Sony headphones in a transit bus and was at the back of that bus yet I noticed significant reduction with the engine noise even when the bus was at speed. This means that these headphones could work well for transit users who do a lot of commuting on buses or diesel-railcar trains.

Other Comments And Observations

Previously I had let a friend of mine who is in to funk, soul and related music try out the Denon UrbanRaver AH-D320 headphones that I was reviewing and he was impressed with them offering the bass response. This time I let him try out the Sony MDR-10RC headphones and he was impressed with the bass response where the bass was there but not dominant.after listening to Earth Wind & Fire’s “September” and Daft Punk’s summer anthem “Get Lucky”. He mentioned that these weren’t the “studio grade” headphones but were much better and lighter than a set he used in the 1970s.

I shared the Sony MDR-10RC headphones with a fellow commuter on the train who was using his own pair of Audio-Technica headphones in order to hear how he thought of the headphones compared with his “cans”.  He noticed a lot more of the noise reduction as well as a deeper bass response compared to what he was used to with the Audio-Technica “cans”.

Limitations and Points Of Improvement

One feature that the Sony MDR-10RC headphones misses clearly is a supplied 6.35mm plug adaptor which allows you to use the headphones with hi-fi and professional-audio equipment that has the larger 6.35mm “jack” for the headphones connection. This can easily be rectified by you having many of these adaptors floating around from headsets that are or were in use and the fact that an increasing number of home audio and AV equipment uses the 3.5mm jack.

There isn’t much else that is lacking with these headphones when it comes to having these as an all-rounder set of “cans”.

Conclusion

I would position the Sony MDR-10RC headphones as a high-quality “all-rounder” circum-aural headset. This is whether as an entry-level “monitor” headset for people starting to show an interest in audio or video recording or DJ mixing; a pair of headphones to listen to your hi-fi system, smartphone, tablet or MP3 player while loafing on the couch or travelling on public transport; or simply a high-quality laptop accessory.

Product Review–Denon UrbanRaver AH-C100 in-ear headset

Introduction

I am reviewing the Denon UrbanRaver AH-C100 in-ear stereo headset which is the cheaper in-ear model of the UrbanRaver series of bass-enriched headsets. These are intended to appeal to people who value the in-ear style of headphones or like their portability compared to a pair of over-the-head headphones.

Earpieces for the Denon UrbanRaver headset

This may be a subjective remark but the Denon Urban Raver AH-C100 can be difficult to wear especially if the headset ear-adaptors that come with it don’t suit your ear canals. Once in place, they don’t cause any fatiguing even for a long journey.

Sound

Like a lot of in-ear headsets and earphones, the quality of the sound for the Denon Urban Raver AH-C100 headset is totally dependent on the earbuds fitting in your ear properly with the supplied ear-caps in place. I even tried using these earphones without the ear-caps in place as if you were to use them like earplugs but I didn’t get the full desireable response from them.

There is the tight bass response that is identifiable with the UrbanRaver headphone lineup but you still hear the “rest of the music” in the songs such as the vocals and melody-bearing or harmony-bearing instruments.

As for non-music content, there is the clear dialogue, and the tight presentation of sound effects coming out of the headphones which makes them work appropriately for private viewing of videos or private gameplay.

I have taken a call using the headset and can hear the correspondent’s voice clearly and they could hear me clearly.

Noise reduction and handling in noisy environments

I have used these headphones during a train journey from Ballarat to Melbourne using a Vline “Vlocity” diesel railcar train. These have a similar engine noise level to most transit buses or coaches as heard from inside the cabin. Here, I was able to hear the music material from my Samsung phone at a reasonable volume without the engine noise competing with the sound.

Motorcyclists who are most likely to buy headsets like this due to them being able to be worn in conjunction with their helmet may appreciate the noise reduction because they can hear what’s going on around them but not as much the noise from the machine under them.

Limitations and Points Of Improvement

There could be further work done on making the Denon UrbanRaver AH-C100 headset fit for most people especially if it could serve also as an “earplug” headset for colder climates.

As well, like with most of the headsets I had reviewed, a break-out plug and/or USB communications audio module would be nice to have to make these headsets work well with online gaming environments. This is more so with “gaming-rig” PCs or console audio adaptors that aren’t likely to have the four-conductor jack.

Conclusion

The Denon UrbanRaver AH-C100 headset comes across as a compact in-ear headset that you can stow away but need to make sure it fits properly every time you wear it for best bass response.

Here, they can come in handy for cyclists and motorcyclists who value using a headset in conjunction with their favourite helmet as they ride their bike on longer distances or want to keep on touch through that bike ride.

Product Review–Denon Urban Raver AH-D320 headset

Introduction

I am reviewing the Denon Urban Raver AH-D320 headset which is a circum-aural headset that can be used with smartphones or as a pair of regular headphones with other audio equipment. These headphones are pitched for most popular music such as dance music by having a strong bass response that can accent the bass line and rhythm.

The headset itself

The Denon Urban Raver AH-D320 headset is a well-built unit with a circum-aural solid-back earpiece design thus allowing for the strong bass response. They are available either with blue highlights or red highlights.

Connectivity

Denon UrbanRaver AH-D320 headset detachable cable

Detachable cable on this headset makes for something that will last a long time

A feature that I admire with the Denon Urban Raver AH-D320 headset is the use of a detachable cord which is able to be unplugged from the headset itself. This allows for a user to replace the cord with another one should the cord is damaged which is something that commonly happens with many headphones and earphones, often having the user write off a pair of headphones when this happens.

The fact that the microphone and controls are integrated in one of the earpieces rather than an inline pod or a boom attached to the headset, and the headset uses a single-sided connection as well means that a simple four-conductor cable with a 3.5mm four-conductor plug at each end can be bought or made up easily should something happen to the cable. It also does away with the need for a boom which can be easily broken off through regular use.

This headset worked with my Sansung Galaxy Note II phone as a proper smartphone headset. The limitation here with Android phones is that the only remote control ability is the multifunction button functionality for starting and stopping music or answering / ending calls.

It also works properly as a pair of regular headphones with most devices that use the 3.5mm stereo headphone jack or a 6.5mm stereo-headphone jack adaptor.

As for durability, these headphones look to me as though they could last a long time. This is through the absence of any earcup supports that could easily break after a fair bit of use and the wiring that exists to pass the sound to the other earcup isn’t just a wire integrated in the headband. Instead there is the use of metal strips that are pat of the headband’s design when you adjust the headphones for your head that does the job.

Comfort

The Denon Urban Raver AH-D320 headset felt tight but didn’t feel very “sticky” even for long journeys. As well, I hadn’t noticed the headband very much because of the use of an appropriate amount of padding. Here, you could wear these “cans” for a significant amount of time without them becoming uncomfortable.

Sound

The Denon Urban Raver AH-D320 headset is very efficient in that you don’t need to turn the volume up to have the sound come through clearly. This is a bonus for headsets that are pitched for portable equipment like smartphones and tablets because if you don’t need to turn the equipment up loud to gain that ideal sound, you are saving on battery runtime. As well, there is a chance for the headset to sound its best without requiring the device’s amplifier to clip.

The music comes across with a lot more bite across the frequencies thus being able to sound clear and without any colouring which could cause fatigue.

I have noticed the very tight bass response but these headphones can sound muddled on some tracks where there is a lot of competition in the bass end such as a bass-guitar along with drums. The other instruments do come across clearly even though there is the preference for the bass response on this headset.

I made a phone call using this headset and the caller’s voice had come across very clearly and they were able to hear and understand me through the headset’s microphone. As well, the headset’s microphone worked properly with Google Voice by being able to pass through what I said clearly to the Android smartphone.

As for use in noisy environments, the Denon Urban Raver AH-D320s worked well by providing some noise reduction. I had used them in the CBD (downtown area) of Melbourne and noticed some reduction in the city noise but was able to hear essential noises that alert me to vehicle presence.

As well, I had noticed a distinct noise reduction when I was using them while sitting up the back of a regular transit bus through a long journey. Here, I was able to hear the program content from my phone even as the bus was at cruising speed and had noticed less of the engine noise. This would improve on their suitability for people who ride on diesel trains or buses where there is the increased noise during travel.

Other Usage Notes

I let some friends who are in to funk, soul, 70s-era American disco and related music try the Denon Urban Raver AH-D320 headphones with their Samsung phones which were full with this music. They tried it with Daft Punk’s northen-summer party anthem of 2013 “Get Lucky” and Stevie Wonder’s classic “Jammin’” and were very impressed with the way these headphones came across with these numbers. One of them who used to be a DJ in the disco heyday of the 70s found that these headphones had a better response to the $1000 cans he used in those days.

Limitations and Points Of Improvement

Denon could provide a microphone-headphone breakout cable and/or a USB communications-audio module as optional accessories for their headsets. These accessories would please gamers who use them as communications headsets for their favourite online games.

They, like other headset manufacturers could provide an inline switch on the cable for switching between Apple or OMTP headset wiring to provide maximum compatibility with smartphones or other communications devices that use either wiring.

Another point of improvement, which could lead to a model variation, would be to offer a Bluetooth wireless variant. Here, they can offer the wireless link that a lot of us crave for our mobile devices.

Conclusion

I would recommend the Denon Urban Raver AH-D320 headset as a cost-effective decent headset that does justice to most popular music. Here, these headphones could come in to play as a step-up from that pair of cheaper headphones that you use with your smartphone or media player or could work as a pair of DJ “cue” headphones.

They would also be a good gift idea for something to give someone who is in to rock, soul, dance or similar popular music and a group of people who pitch in together for these headphones, like a couple or family, can ease the burden when it comes to purchasing these as a gift.

Statement Of Benefit

After realising that there was a friend of mine loves his rock music wery much, I have purchased a set of these headphones close to Christmas to give to him as a gift. I was able to purchase the set for AUD$99 off the recommended retail price effectively from the distributor’s warehouse door.

A small amplifier to get those bookshelf speakers connected to your computer

Article

Lepai LP-2020A+ Review – Amplifiers/Preamps/Processors – CNET Reviews

My Comments

You may have gone to that garage sale, car-boot sale or flea market and picked up a pair of small bookshelf speakers thinking that they may be good for your stereo or PC. Or you have a pair of these speakers lying around in the cupboard or garage either because the music system that they were bought with had died or you had upgraded the speakers on that music system to some larger meatier ones.

But you really want to then use those speakers with your computer, smartphone, tablet or other similar device to punch out some music. These kind of speakers really need to work with an amplifier and when you are dealing with a pair of small bookshelf speakers, they don’t expect much power to drive them.

Lepai have come out with a midget amplifier that can put up to 20 watts per channel for this kind of application. It only takes up a very small amount of desk space and runs from a 12 volt DC power supply, something which I would suspect is cross-bred from car-stereo technology. Here, the workhorse is a Tripath digital “switch-mode” amplifier that has been rated for a smooth high-quality sound equivalent to a valve-based “general-purpose” hi-fi amplifier of the late 60s.

This amplifier has two line-level connections – one with regular RCA sockets and one with a 3.5mm stereo jack. But these inputs are open at the same time and could benefit situations where you may want to play music from a portable player or hi-fi component yet be able to hear audio alerts or game sound effects from your computer.

What had impressed me about the Lepai LP-2020A+ amplifier was the idea of it being a cost-effective midget utility amplifier that can work with most small speakers made through the decades and can amplify the sound from most audio equipment such as the laptop computer. In this case, this amplifier and a pair of good-quality small bookshelf speakers could become a cost-effective alternative to a pair of cheap computer speakers.

Product Review–Denon MusicManiac AH-D600 Audiophile Headset

Introduction

I am reviewing the Denon MusicManiac AH-D600 audiophile headset which is a pair of closed-back circum-aural headphones pitched at those who value their music. They have a long replaceable cord to connect to the computer, amplifier or CD player but they also have a separate mobile cord with an integrated microphone pod that converts them in to a headset that works with your smartphone or laptop for communications purposes.

The headphones with the regular cord for use with your hi-fi

The Denon MusicManiac AH-D600 headphones come with two separate cords that plug in to the earcups. One of these cords is a long one that has a cloth-effect insulation for use when listening to your hi-fi or laptop whereas the other is a short headset cord with a pod that houses three control buttons and a microphone, thus making it become a mobile headset for your smartphone.

All the plugs are gold-plated for optimum connectivity to the headset and the device you are using. As well, the separate mobile cord can work in “headset mode” with both the Apple iPhone and the Android handsets, the latter of which I tested for myself where it worked properly with my Samsung Galaxy Note II during a test call.

I also like the concept of the detachable cords because you can easily repair broken plugs or replace broken cords, thus allowing you to gain a lot more mileage out of these headphones.

Comfort

The Denon MusicManiac AH-D600 headphones are comfortable to wear for a significant amount of time even though they do feel heavy. This is brought on through the use of leather earcups, which can be sweaty at times with hot weather. Of course, you can’t feel the headband when you wear them due to a well-cushioned headband design.

Even for a pair of circum-aural headphones, you don’t find that the speaker grille in the earcups doesn’t touch your ears at all and you have a cloth speaker grille rather than the typical plastic or metal-mesh one that can be par for the course for this headphone class. This makes it appeal to you wearing the headset for a long time compared to most headphones of this type.

Sound

The Denon MusicManiac AH-D600 does satisfy the expectation associated with a pair of good circum-aural hi-fi headphones.

I have listened to a range of different music content on these headphones and have noticed tight bass with clear sound for the popular music including the current dance and R&B music. Here, the bass didn’t dominate unnecessarily while you could hear the vocals and lead instruments clearly. For classical music and other music that requires detailed listening, the Denon headphones still lived up to that ability, allowing the instruments to be heard individually.

I placed a “confirmation call” to the public-relations agency who lent me these headphones using my Samsung Galaxy Note II and the headphones with the “mobile” cord to observe how they performed as a headset for a mobile phone. Here, I heard the staff member’s voice very clearly through the headset and they heard me clearly from the microphone on their telephone equipment. This feature comes in to its own for use when you use your smartphone as a music player while you are on public transport. As well, the centre button on the microphone module works as a call-control button for Android handsets as well as iPhones. But you don’t have audio control for anything other than the Apple iOS platform.

You do have very significant noise reduction which may be a boon for noisy transport environments, but it may be at a disadvantage if you are walking along the street and need to hear the traffic.

Limitations and Points Of Improvement

The Denon AH-D600 with its mobile headset cord could appeal to some teenagers and young men as a gaming headset due to reduced ambient noise so you could hear that other player talk to you. But this ability is limited by Denon not supplying a headphone / microphone breakout cord or USB communiactions audio adaptor to allow it to work with a PC for talking with your comrades while playing that MMO game. Here, they could offer the gaming interface cables and adaptors for PCs or consoles as optional accessories.

Other than that, I have found very little to fault this headset as a premium all-purpose pair of circum-aural headphones

Conclusion

I would position the Denon MusicManiac AH-D600 as an all-purpose music-grade circum-aural headset that cam be used where you want to concentrate on the audio content. It doesn’t matter whether you are on the train or plane listening to music on that smartphone, tablet or laptop; you want to listen to that CD or record in detail through that good amplifier, you are doing some serious recording in the studio or with that good recording device; or are wanting something as an alternative to the fashionable DJ headphones as cue / monitor headphones for your DJ work. The headset cable will also come a long way with communications devices (including mixing-desk talkback setups) that exploit the standard headset plug wiring used for mobile phones.

For that matter, I would recommend these headphones as a major-special-occasion gift for someone in your life who loves their music very much. This could be something like a major birthday. graduation or retirement gift and could be best purchased by a group of people like a family.
