Let me get straight to the point. For $49, I don't think you can find much better -- the MEE Audio M6P offers a lot for its price range, especially when pitted against similarly-priced earphones. A combination of superior build quality, design, aesthetics, and accessories represents these headphones as a whole new concept of value. And I already thought the original M6 was a steal at $20!Packaging was rather straightforward and simple to open, with a clever pull tab to access the content. Inside the box, I was surprised to find that there were a ton of accessories. I did not expect anything other than the typical silicone tips and carrying case. Included with the M6 PRO, you will get:- Two cables: basic & playback control/microphone- Silicone Tips: small, medium, large, bi-flange, tri-flange (2).- Comply T200 Memory Foam Tips ($15 alone!)- 1/8'' to 1/4'' stereo adapter- Hard carrying case: soft touch neoprene?I was impressed with the accessories, as alone they are worth half (if not more) the total package. The case is very nice, I provided a picture as to how I organized all of the accessories into the case. I keep the whole package in my car for when I'm on the go, and haven't had any problems at all on fitting everything in there.BUILD QUALITY: 9/10-Let me get started on the design -- everything is rock-solid here. On close up inspection, I can see that the clear housing is held together by glue on the edges; however, I cannot feel any gaps in between the plastic. The finishing is very smooth and well done. I would assume that their statements on the sweat-resistance to be true. The connection point between the cable and the headphones is very strong as well. It took quite some effort to detach, after popping them in the first time. They always give a resounding 'click' when being plugged.And don't even question me on the cable -- it's quite possibly my favorite cable, out of all my IEMs, out of all my full sized headphones. This would be one of my favorite aspects improved over the predecessor, the original M6. Not only is it detachable, but it feels so much higher in quality, and looks so much nicer as well (specifically the audio-only cable, not the remote/mic). It's a matte, frosted white, with the two white stereo separation cables twisted inside the outer sheath. The texture is the perfect grippiness, not too sticky, and not too slick to the point where it feels cheap. If it breaks (which I don't foresee in the near future), I'll be replacing it immediately.COMFORT: 7.5/10-There doesn't seem to be much change from the previous M6. The M6 series is an over-the-ear IEM, which means it was designed for the cable to wrap over the front and top of the ear, going down behind the back -- what this allows is a more "secure" fit, preventing the earphones from falling out with excessive movement, and reduces mirophonics (noise travelling up the cable from brushing things i.e. your sleeve). I had slight difficulty finding the right tip for me -- I generally stray away from tri-flange, but for some reason, the bi-flange didn't work for me here as well as it did with the original M6. When pulling out the earphones, they would almost always flip inside out, which makes it very difficult to make slight adjustments to the fit. As for the foam comply tips, I was excited to try these. While they were a guaranteed fit, they took significantly more work to put in, compared to the silicone tips. They also attract more dust and earwax. I found myself most comfortable with the large silicone tips.With daily gym usage for about two weeks now, I can say they have a very secure, snug fit. The memory wire works better than the previous version, and the texture is more "soft-touch" than the old glossy material. However, I did notice that I would have to adjust the driver housing every now and then to alleviate some pain from the housing touching my inner ear. Nothing too bad though, I've had much worse.Something notable would be that the headphones lie really flat against your ear, so you would have no problem laying on your side with these earphones in.SOUND: 7.5/10 (price relative)-Of course, sound is all relative. You're not going to get top-level IEM quality, or full sized headphone soundstage here. Realistically, and compared to the competition, this headphone definitely ranks up there. In comparison to the previous M6, this is much colder and a lot more analytical. The lows are much more laid back than the previous (which, in my opinion, was rather bassy). Another change I noted was the increased brightness, treble was louder than normal. Unfortunately, in some songs and notes, the highs were almost piercing and forced me to turn down the volume, thus reducing the overall satisfying fullness you get from the right volume. The result is a very "airy" sound, which is what I've become accustomed to -- a lot less fun sounding than the previous version, but not necessarily a bad thing. I would say that it is remarkably similar to (only stating out of headphones I own) the Audio-Technica AD900x/700 without the expansive soundstage. Not really the best thing if you're looking for bumping bass, but perfectly fine if you're more interested in detail and high notes.But a question that comes up often is whether one should either upgrade from the original M6 -- I personally wouldn't call it an upgrade, but a sidegrade. They're sort of different in sound. Basically, the old M6 is more fun and probably more suited to hip hop, RnB, electronic (house, DnB, dubstep), and more bassy sounds. The new M6 Pro still has that bass punch, but it's not so in-your-face as the old version. It's a nice low end with good clarity, being tight and controlled.OVERALL: 8.5/10 (fantastic)+ Ton of accessories+ Stellar build quality+ Detachable cables at this price+ CABLE QUALITY+/- Decent comfort- Visible glue- Sibilance, harsh high notes at times- Typical IEM soundstageI have now named this IEM as my gym-going earphones, and absolutely love the overall feel and quality of them. I would highly recommend them for anyone looking for some daily headphones, especially if you're looking for build quality and accessories. Having only tried the M6 line, I hope to try any future models of MEElectronics earphones.
