MEElectronics Air-Fi® Matrix2 AF62 Stereo Bluetooth® Wireless Headphones

 
First of all, I want to thank Mike from MeElectronics for providing me with a free sample for my review, as well as the friendly and quick E-Mail correspondence.
I remember trying to get into wireless audio transfer via Bluetooth some years ago, but have to admit that it was quite a remarkable catastrophe as sound quality lacked clearly behind wired audio transfer and was full of artefacts, audible compression and far from good sound, wherefore I gave up this idea and stuck to wired audio transfer therefore.
Years have passed and Bluetooth audio development has advanced, so let’s see how the Air-Fi Matrix² asserts itself in general and against the wired Shure SRH440 which is about in the same price range.
 
 
Before I start with my review, I want to tell you a little about myself and my preferences, so you get a better perception of who you are dealing with. I’ve gotten into higher-end audio some years ago and have expanded my collection of gear, especially headphones, since then (you can see my current inventory by clicking on my profile). Having developed a good knowledge, I started writing multiple in-depth reviews (in German) as I love writing, and gave purchase advice.
Though I am listening to higher-end headphones most of the time, especially when concentrating more on the music, I also like purchasing cheap stuff from time to time, just as the Brainwavz R1, as I love to evaluate how well they handle and I even like using the rather inexpensive stuff when being on the go with less concentration on the music or just sometimes in-between.
The main genres I listen to at home are jazz, elder rock and pop music, some classical, instrumental and acoustic music with a preference towards neutral headphones and IEMs.
On the go and in-between, I prefer listening to more modern pop and rock music, as well as electronica, some metal, very little hip-hop/rap and some acoustic and chamber music, with a preference of neutral-ish or balanced headphones that tend to have either a slightly v-shaped or darkish sound signature (from time to time, I also find myself desiring a more “extreme” sound signature on the go). Most of the time, I listen at rather low volume levels.
 
 
Let’s go on with the actual review:
 
The Air-Fi Matrix² comes in a surprisingly slim package with the typical MeElectronics design I already know from their A151 IEMs I bought many months ago. On the inside, you find a nice carrying case with carbon fibre design which contains the headphone, as well as a short manual where the most important operations and features are nicely described, along with a cable with straight 3.5 mm connectors to use the headphone in wired mode, plus a short micro USB charging cable.
 
I was quite surprised about the headphone being quite lightweight and producing only little clamping pressure and being rather small in size, though my rather big ears fit pretty well into the very soft ear cups, except from my earlobes, which are yet just about covered by the soft ear pads (though, there could be just a bit more depth as my ears are touching the inside of the cups resulting in a little pain when listening for a long time). Even the headband is made out of very soft material, making the Matrix² extremely comfy to wear.
Though at close sight the headphone looks a bit cheapish, it lacks of any flaws in build quality, with all stitches being even and all screws being tight. At further Glance the Matrix² looks even quite stylish and modern with the nice and soft carbon fibre imitation being surrounded by the glossy silver plastic ring and the matte-black finish.

The headband’s size adjustment mechanism and the rotary ear cups appear to be quite stiff and the left/right marks are barely visible being in a rush, with the left side also lacking of the typical three vertical dots, making it less easy to put them on the right way when you are in a hurry.
 
The media buttons need a certain amount of force to be pressed and are accompanied by a rather loud mechanical “click” when on the head, but it’s not too bothering when music is played.
Speaking of the media buttons: there are three on each side, providing you with all of the functions you probably know from an extended in-line remote control.
Starting on the left ear cup, you have the on/off button next to the “+” and “-“ buttons for raising or lowering the volume, next to a small LED indicator that flashes blue when the headphone is turned on and starts shining continuously when it is connected wirelessly, as well as the built-in microphone (its voice quality could have been better though it is quite okay) which is covered by a black metal mesh.
On the right ear cup, you find the play/pause button which is surrounded by the two buttons that are responsible for skipping to the next/previous track.
What I found somehow illogical was that both the “+” and “>>I” buttons are located on the back instead of the front, but I got used to it real quick.
 
Noise isolation is rather poor, especially in the lower frequencies, so traffic noise won’t really be blocked as much as with the Shure which isolates mid and low frequencies quite well. In terms of high frequency isolations, I found both to be quite equal.
Usage in noisy environment isn’t the best field of application for the Matrix², therefore I think they are better in less noisy areas such as at home, when hiking or in the office, though they will leak some sound to the outside when listening at higher volume levels.

Let’s get them connected:
 
Pairing the headphone with your Bluetooth device is quite easy as you just have to turn on BT on the transmitting device (make sure it is set to be visible), press the power button to turn on the headphone and keep it pressed for a couple of more seconds to enter pairing mode which is indicated by the status LED flashing red and blue and a female voice (which is also present during turning the headphones on and off) giving you the necessary information you need to pair your device.
With all of the three tested audio sources (BlackBerry Q10, iPhone 4, Windows 7 laptop), pairing and connecting didn’t take long.
Once the headphone has been paired, it will be saved in your mobile’s Bluetooth settings and will most likely allow you an automatic connection for the next time you turn on the headphone (it is depending on your device and settings).
 
With the iPhone and PC, you kind of set the "volume pre gain" on the device’s media player and control the volume on the headphones, whereas with the BlackBerry there was no such thing as a separate volume control, resulting in a button press on the headphone and the mobile itself regulating the same volume with a negative side effect of the lowest possible volume being above my usual listening levels (this is a "normal" behavior of Bluetooth devices when being connected to BT sources, so it is not the headphone's fault).
A cool feature the Matrix² has aboard is multipoint connectivity, which means that two Bluetooth devices can be connected simultaneously, with one of them acting as media player and the other as telephone. Once a call is incoming, music playback is paused automatically and resumes just as the call is being hung up (the Matrix² also allows call controls, which are described in the manual). It can also be used to play a song with device A, then pause its playback to play another song on device B. Switching devices takes only a few seconds most of the time, but sometimes the latency is longer.
Bluetooth range is pretty astonishing with a minimum of eight meters with the PC (one wall in between) and 15 meters with the BlackBerry (two walls in between) before connection gets partly lost. I remember that years ago, five to eight meters were about the maximum distance I could achieve, but there were much more interruptions involved.
Battery life is pretty amazing – MeElectronics states the battery to last for up to 22 hours, but I got a nice amount of 25+ hours out of continuous playback with volume levels being a bit above average (PC, no aptX, high quality MP3s).
Another neat feature the Matrix² offers is that with most iOS and Android devices you get a small battery indicator next to the Bluetooth symbol, so you approximately know when you have to “fuel up” your cans the next time, but for the case that you run out of battery and don’t have access to an electrical socket, there is a standard 3.5 mm connector located on the back of the left ear cup (yeah, that’s probably not the best position but wasn’t bothering me at all) to connect it to your device via cable.

Let’s get on with the probably most interesting part, the tonality and sound quality:
 
Before listening, the Matrix² got about 50 hours of burn-in, just in case if there are any effects of burn-in (which I personally doubt in general when it is about headphones, but as this is a review and Head-Fi, I wanted to clarify it).
Tested music files were mainly lossless CD-rips (FLAC), some high quality MP3 files and a minority of AAC files from iTunes.
By the way, hiss is very low with Bluetooth and inaudible with music playback being started.
Tonality-wise, the Matrix² is balanced sounding, but rather on the bassy and slightly dark side of balanced.
Extension on the lower end isn’t bad at all, though I could hear the bass declining below 40 Hz. 30 Hz are yet loud enough though audibly quieter, but below 25 Hz, there wasn’t really much going on, which doesn’t bother me at all as this area doesn’t include much relevant tonal information anyway.
Upper bass and mid bass are moderately emphasised; I’d say about 3 or 4 dB. From mid bass towards lower bass, the level decreases. Ground tone area is free of any emphasis as far as I could tell.
Mids are neither recessed nor emphasised but just right.
The Shure SRH440 has got an overall more neutral bass but doesn’t extend as low as the Matrix², with a quite steep decrease below 50 Hz.
Upper mids and lower highs are audibly recessed, giving voices a slightly darkish timbre.
The Shure’s mids and therefore voices are, to my ears, tonally correct.
At 3.1 kHz I could hear a pretty steep dip when sweeping with a sine generator.
Level increases from mid highs to upper highs, though they still are a tad below neutral, giving the Matrix² a slightly “smooth” and “laid back” signature along with the recessed presence area.
Treble extension is quite good and reaches up to 15 kHz without too much decrease.
The Shure has got more level in the lower highs and an overall brighter treble.
Sweeping didn’t show any annoying peaks in the Matrix²’s frequency response.
As I prefer a neutral-ish or slightly dark/bassy sound signature on the go most of the time, the Matrix² fits in quite well with its balanced yet darkish-bassy tonality.
 
Let’s continue with resolution and bass quality:
 
Overall, the Matrix²’s resolution is on a good level, albeit it is settled a bit below the Shure’s which outperforms the MeElec a bit, especially in the bass and also slightly in the treble and carves out some more details.
The only real flaw I can attest the MeElectronics is the bass quality below 100 Hz. The upper bass is, regarding the price, yet pretty dry and clean, just as the Shure’s, but the lower the bass extends, the slower and spongier it gets, with a somehow dull and undifferentiated feeling towards it, also sometimes making the lows appear to be thicker than they actually are – that’s when being connected wirelessly.
As soon as I used the Matrix² in wired mode, lows gained more control and lost the spongy response, albeit still falling behind the Shure’s in terms of dryness and precision and couldn’t get rid of the dull and slightly undifferentiated feeling.
 
Let’s talk about the differences in highs reproduction in comparison between wired mode, wireless mode with aptX and wireless mode without aptX.

There is a very tiny difference between wireless connection with and without aptX, but the biggest, yet still rather little difference is between wired and wireless mode, with the wired mode reproducing more refined highs with slightly more details.
Again, the Shure is a bit above the MeElec, but way less than I had expected.
 
Soundstage:
 
Soundstage is pretty good for a closed-back headphone and gives a pretty balanced expansion both in width and depth. The Shure, which provides a pretty good soundstage for a closed-back headphone, too, isn’t better than the MeElec in this regard, though it provides the more refined instrument separation.

Conclusion:
 
Bluetooth audio has clearly developed within the past few years and doesn’t lack much behind wired audio transport anymore.
Regarding the price, the Air-Fi Matrix² AF62 delivers a coherent performance with a great price-quality ratio and doesn’t lack that much behind the Shure SRH440 which is about $10 more expensive, though the MeElec has got less space in the shells due to the wireless audio transport electronics, the built-in battery and the fact that you also pay for the wireless transport, including the fees for the audio codecs and the price for the electronics themselves.
I’d even say that the qualitative difference between the Matrix² and the SRH440 is a bit less than a subjectively perceived half of a class.
This shows that for less than $100, there are halfway good sounding wireless headphones that don’t lack super much behind fully wired headphones.
Furthermore, I am pretty certain that within the next few years, portable wireless audio transport will develop even further, coming closer to filling the yet existing gap between wired and wireless headphones, though it so much smaller than some years ago.
Kudos, MeElectronics, you have developed a pretty balanced and relatively decent sounding headphone offering an audio performance you wouldn’t expect from a Bluetooth headphone this inexpensive.

Before I begin my review, I would like to Thank Meelectronics for providing me with a review sample in exchange for my honest opinion.

It seems that everywhere you look you see another new pair of wireless sports earbuds or wireless speakers.  Makes sense since a lot of people use their smartphones for media storage and don’t want to be bothered with wires while exercising or listening to music at home or outdoors.  But sometimes you just want to enjoy a private listening session where sports headphones won't provide enough comfort and speakers are the opposite of privacy.  That’s where full size wireless headphones come into the picture.  Unfortunately, wireless full size headphones are not as common as in-ear models, they cost a lot more, and some add noise canceling which could be either a blessing or a curse.  Though not a new release, Matrix 2 from Meelectronics still represents an excellent value for under $90 considering its build and sound quality that can easily go head-to-head with some other models that cost at least 2x as much.  Here is what I found when I got a chance to test these Bluetooth wireless headphones.
 
I knew beforehand that Matrix 2 supposed to be a full size over ear headphones, but I didn’t expect a packaging box to be that slim, even for a folding pair of cans.  Both the front and the back of the packaging box have a high res picture of Matrix 2 that almost ready to pop out of the carton.  As usual, you can read a plethora of useful info going over the spec, controls, and the technology behind these headphones.  The part that stood out for me the most was Bluetooth 4.0 support with apt-X and AAC codecs and up to 22 hours of playback time.  Perhaps it’s not exactly groundbreaking by the standards of today's releases, but considering these headphones came out 2 years ago – I think it was impressive how Meelec future proofed their design.
 
Out of the box you get a very slim form fitted hard shell case with a carbon fiber finish to match the headphone look.  Obviously, it’s not a real carbon fiber and rather a printed (or stamped) finish, but nevertheless it looks sharp and feels like a quality case.  Along with a case, the other included accessories were usb to micro-usb charging cable and a basic 3.5mm to 3.5mm audio cable.  I believe during Matrix 2 initial introduction it was a time when a lot of companies were transitioning from AAA batteries to rechargeable batteries.  So this is another example of how Meelec made the right choice introducing a higher capacity rechargeable battery with a common smartphone/tablet micro-usb connector.  As a backup, in case if you run out of juice after continuous 22hr playback, you can use any standard or included 3.5mm cable to driver these headphones from HO of your audio source.
 
Unboxing and Accessories.
 

 

 

 

 

 

 
 
As I already clued you in, Matrix 2 folds flat for a very compact storage.  This is where I have a little gripe with a design.  Perhaps the rotation joint between the headband and the yoke (y-fork part holding earcups) will wear out after some time, but out of the box and even after a few weeks into my reviews I felt it was still stiff and I had to apply a little bit of force to rotate them.  I’m used to headphones with looser joints that allow an easier “self-adjustment” rotation of earcups around my ears.  I have a feeling they might get looser after awhile, and my impression is based after first 2 weeks of use.
 
But regardless of that, the idea of folding flat design with a slim case is great when you are traveling or just concerned about safety storage of your headphones.  Also, just like you find a faux carbon fiber finish on the exterior of the storage case, you can see and feel the matching finish on outside of earcups and the top of the headband, except it’s printed on a softer vinyl material.  When it comes to carbon fiber finish, there is a very fine line between tacky and classy, and Matrix 2 definitely fits the classy definition of it.  With an exception of plushy padding covered by soft pleather on the inner side of headband, the rest of the material is a lightweight durable plastic with a nice soft touch finish.  This matte finish was actually great in resisting fingerprints, a common problem with other glossy piano finish headphones.
 
The headband height adjustment has a precise click mechanism and you can see inside a reinforcement metal steel band which bends and twists without any creaks or squeaks.  In general, Matrix 2 has a very comfortable clamping force and it was great to wear these headphones for extended period of time.  Just don’t expect too much noise isolation, due to earpads being a bit on a shallow side and in combination with softer clamping force.  Though earpads were not as beefy, the opening was large enough for a comfortable fitment without my ears touching the driver.  The only other comment I have about overall design is that I wish L/R marking outside of earcups would stand out more for an easier ID.
 
Design.
 

 

 

 

 

 

 

 

 

 

 
 
With a closer look at both earcups, you will find a lot of physical control buttons and a few other ports.  Unlike some other manufacturers who try to combine controls into multi-function buttons, here Meelec partitioned almost every control with a separate dedicated button.
 
Starting with a left earcup, you have a microphone and 3.5mm headphone port, though port comes out from a side on the back rather than traditionally from the bottom.  Not really a showstopper, just something different, and perhaps more convenient to use with a right angle 3.5mm audio cable.  A three dedicated button controls on this earcup are for Power (and Call), Volume down, and Volume up.  To distinguish the buttons without looking at it, Power button is smooth while Volume buttons have a bump so you can find them easier by sliding a finger.
 
The right earcup has micro-usb charging port with a tight cover, and three dedicated transport control buttons with Skip next/prev and Play/Pause in the middle.  Here, the middle button is smooth while skip buttons have a bump to easily distinguish these as you slide your finger.  It does take a short while to get used to this arrangement, especially since other headphones use Play/Pause/Call while here Call is together with Power button.  Also, due to a distinct set of control buttons on each side, I was able to use that as L/R side guidance without even needing to look up earcup marking.
 
Earcup controls.
 

 

 

 

 

 
 
When it comes to Bluetooth wireless performance, it was in line with most of the other wireless headphones I tested in the past.  Pair up was fast and easy, and audio performance was solid across open space of 35-40ft.  Within working range, I didn’t experience any hiccups or drops.  Furthermore, Matrix 2 also supports NFC pair up which some people might find convenient.  When it comes to making calls, I feel a little awkward doing that with full size headphones because they cover my ears and I can’t hear myself while talking and end up shouting.  But if you receive a call during your music listening session, it’s always convenient to be able to pick it up without taking headphones off.
 
BT pair up.
 

 
 
Even so in the past people were looking at Bluetooth wireless headphones for convenience of cutting the cord, today most of the consumers put wireless sound quality on an equally important level.  With introduction and support of apt-X codec (I’m 100% Android so it’s important for me) sound quality definitely went up for many headphones, thus everything comes down now to a driver design and a sound tuning.
 
After close to 100hrs of burn in, I found Matrix 2 to have a balanced smooth clear sound signature.  Low end has not a bad extension down to a sub-bass with a moderate rumble and a less aggressive relaxed mid-bass, all under control and without spilling into mids.  It was great to hear a bass slightly north of neutral and without any bloat.  Mids were warm and smooth, with lower mids being thicker while upper mids being pushed slightly back (not recessed though).  I went back and forth with mids, the reason why I got close to 100hrs of burn in, and came to a conclusion they were lacking a bit of clarity and definition.  But it was a very easy fix with 3dB boost around 3kHz which had a significant improvement effect especially on vocals, making them less nasal. Treble was smooth and a little bit rolled off, but still clear and not sibilant.
 
I'm usually not a big fan of EQing a sound, especially when it comes to wireless performance, but I really felt these headphones were worth it.  Plus, I was curious how they compare to some other selective headphones in my review collection.
 
Sound Comparison between Meelec Air-Fi Touch, Pendulumic Stance S1+, Sennheiser Momentum 2 Wireless, and Meelec Matrix 2.
 

 
 
- vs Matrix 2, S1+ ($199) has a more neutral sound with less sub-bass and punchier mid-bass, lower mids are thinner and upper mids have more clarity, also it has a better treble extension; soundstage is very similar; due to a heavier weight S1+ has less comfortable fitment.
 
- vs Matrix 2,  Momentum 2 ($499) has a more refined bass with a deeper sub-bass and a faster mid-bass punch, similar mids with just a little more clarity and definition, and a little better treble extension; soundstage is wider; also build quality at that price point is better, though they both have a comfortable fitment.  Overall Momentum sounded a bit more colored while Matrix 2 sounded more organic (especially after EQ correction).
 
- vs Matrix 2, Air-Fi Touch ($99) has a similar balanced sound with a tighter bass, more detailed and clear mids, a similar treble, and a similar soundstage.  I was uberly impressed with this comparison considering Air-Fi Touch has on-ear design where quality of bass usually suffers, but not in this case.
 
Conclusion.
 
In my opinion it was very impressive to review a design of full size Bluetooth wireless headphones released a few years back where it still feels ahead of the curve in comparison to some other recent releases.  After a small EQ correction, I found Matrix 2 to really shine with a smooth balanced sound signature and some surprising clarity and details (again, taking EQ boost at 3kHz into consideration).  They are not intended to indulge “Beats” bassheads or to persuade seasoned audiophiles or to offer dead-quiet noise isolation during your public transportation ride.  What they intended for is to give you hours of uninterrupted and non-fatigue listening pleasure without reaching to your phone or tablet since all the controls are right around your ears.  Based on its sound quality (including support for BT4.0 + aptX), build quality, extended battery life, flexibility of using both wired and wireless, and a cool storage case – Meelec Matrix 2 is one heck of a value under $90!

Me: I am a 21 year old student living in a small town in India. I would like to call myself a music enthusiast, rather than an audiophile. I was inspired by music since childhood, and as the time passed, the passion of music grew in me, and that subsequently led me to join Head-Fi. Eventually, I found the pleasure of listening to music mainly by the HD600 and recently, by the seductive LCD2 headphones, and realized the true components of recorded music. I usually like to listen to Indian Classical Music along with Bollywood songs. My main listening genres include classical, vocal, instrumental, jazz and sometimes pop.

Their products are very reasonably priced, accessible for a common music enthusiast. MEE provides are a great price/performance ratio on their entire product range.
 
MEE’s Motto: Music Enjoyment for Everyone.
 
Specifications of Matrix2 as per MEE:
 

---

 
Packaging and Accessories: The Matrix2’s arrive packed inside a strong white MEE style-cardboard box, on which features and other information have been mentioned upon. Once the box is lifted open, The Matrix2& its case can be slid out. Packaging is safe yet attractive, nothing to complain about.
 

 

 

 
List of Included Accessories:
 
Storage Case:  Strong fiber storage case to store and carry the Matrix2 headphones.
 
Headphone Cable: One 1.25M three pole 3.5mm audio cable for wired operation on Matrix2.

 

USB Charging Cable: Standard black coloured USB cable to charge the Matrix2

 

User Manual: Detailed and informative Instructions about operation, also contains warranty information.

---

 
Design and Build: The Matrix2 has a cutting edge & innovative build with very good quality workmanship. Nowhere to nitpick on.
 

 
The entire housing shell is made up of high quality, light weight & latest tech carbon fibre, and is painted in matt rubbery black for better grip and anti-skid feature. These are light in weight. Left and Right markings are a little hard to see, and are clearly indicated. Headband & earpads cushioning are made up of soft pleather materials. The length slider is made up of polished metal, which ensures this area, which is under tension, does not break off. The Matrix2’s are already nimble, easy to handle, wear on and power requirement is very low. Along with all these are easy to carry around. 
 

 

 

 
Since the Matrix2 is a Bluetooth headphone it has internal rechargeable battery, and recharging point is a mini USB, & is expected to be charged from a 5V USB line. The Matrix2 supports Bluetooth V4, & the host device is supposed to support the BT v4 for a pairing to achieve.  Battery life is expected at around 20 hours. The Matrix2 also supports wired playback incase Bluetooth is no longer required. The socket for the cable is again a very common and convenient 3.5mm type. It also has play, pause, forward, backward and volume keys on lower side of the headphones.
 

 

 
Functions: When switched on & paired with a smartphone, the Matrix2 works flawlessly in terms of wireless operation. No interruptions or distortions. Clean transmission. The control buttons are very well designed, and are solidly built, and perform well.

---

 
Comfort:  Matrix2’s are very comfortable to wear, and its yoke is long enough and hence comfortable for almost any-sized heads. Matrix2 is ergonomically designed. But since the earpads are madeup of pleather, ventilation will be less, thereby causing sweating; especially in tropical climate. But it can be continuously worn over an hour without any discomfort issues.
 

 

 

 
Since Matrix2’s are closed back headphones, these will isolate the listener from outside noise. This level of isolation is good enough for a traveller. Going by weight factor, these feel light and go easy on head. Clamping force is relaxed and not at all imposing and pressing against ears. Headband has a good cushioning.

---

 
Sound: As for the most important part, the Matrix2 in overall has a near-neutral & clean sonic character.
 
Burn in: There is little or no sonic change with time. Let’s say a usage of 5 hours gives us softening of pleather earpads and a personalized clamping force. Bass prior to break-in is slightly muddy, and eventually it becomes more accurate, Mids will sound clearer and natural. Highs become slightly smoother; soundstage opens up by a margin.
 
Lows: are slightly loose and give a sense of full bodied bass, and are decently accurate.
 
Mids: sound very neutral clean.
 
Highs:  Slightly smooth treble.
 
Soundstage: Matrix2’s soundstage is good enough (for a BT can) with nearly circular soundstage. Width & Depth are balanced, decent. Instrument separation is good for a BT headphone at this price.

---

 
Amplification: The Matrix2’s are rated at 64 ohms, and designed to be power efficient, and hence are fairly easy to drive, and can be driven by almost any sources, smartphones and DAP’s. Although setup like an O2/ODAC does indeed increase accuracy, soundstage and dynamics, and the difference in quality is definitely audible. Power is not very important aspect here, but a transparent setup indeed does help in increasing SQ; It is easy to observe that sound quality audibly increases on wired mode on same headphones, than wirelesss BT mode.

---

 
Conclusion:  The Matrix2’s are really appreciable set BT of cans, one of the most performing & affordable BT cans to music enthusiast out there. Build quality is very good, sonic presentation is great for a wireless headphone with fairly good soundstage. Matrix2’s functions are also very fine and work flawlessly. At a competitive price of 90$, these offer a great price to performance ratio! Really a option worth looking for joggers, travellers and enthusiasts who are on the move.
 
Pros:
 
1) Build Quality: The Matrix2 has an excellent metal/fiber build. Latest tech’s like carbon fiber is employed.
 
2) Sound quality: Sound presentation here is very neutral, clear & detailed. Appreciable sound quality for a wireless headphone.
 
3) Function:  Matrix2 has a very reliable yet wide features and functions in it. It can go wired or wireless, has complete music control including a high quality mic embedded in it.
 
 
Cons: Clarity & balance in sound quality could use improvement, but again due to wireless features & wide functions, there will be a compromise in sound quality, which is common for all BT headphones.

Received my AF-62 Headphones today! Tested with Nexus 5 and Google play music app
 

1. NFC pairing didn't work the first time. Had to do manual pairing with blueooth. From OFF hold power for 8 seconds and headphones will go in pairing mode then just search for bluetooth devices on your phone and viola
   1. After the initial pair NFC works great. Turn on Headphone, Touch phone to left cup and musice starts playing
2. Sound: Much Much better then I expected from a bluetooth Headphone. It is fun, not critical. Not super immersive but just enough to keep you listening. Its not as fun as my shure SE215, Not as balanced or clear as my Westone 3 but they are In ear monitors and these are heapdhones. The sound from these sounds like your music is a little far away from you, rather than right in your face. Also you have to turn it up to uncomfortable levels to hear any real bass. This may change with burn-in and equalizer settings. 
3. Comfort: Good for headphones I think, they are light, no fatigue after half hour. The pads aren't super comfy but they don't hurt either. My ears are getting a little hot, but I sort of bought them for the Canadian winter so I don't have to wear ear muffs.
4. Quirks: 
   1. (1) Phone media volume and headset volume seem to work independently. seems like a hassle 
   2. (2) The Fwd/Rwd are track skip (back or forward) only, they won't actually forward or rewind a song. 
   3. (3) I couldn't get the calls to go through the headset until I received a call. After that outgoing and incoming are going through headset properly. Might be android issue
   4. (4) I can't activate google now with the headset. This may not be a quirk but and android functionality. Will investigate later.
5. I haven't really tested call quality yet
6. I haven't tested them with the wire yet, because well I bought them for bluetooth first and foremost
