Honestly, I'm very pleased with the audio quality of these headphones. For the price, as the title suggests, these are very impressive. I had read several reviews of these headphones before finally deciding on them. Having now used them for several weeks now, I'll give you my review. What I liked: The highs are very nice and detailed, but become very harsh at or above about half full volume. Mids are decent, if not a bit recessed. Lows are very good and surprisingly very tight for a headphone of this ilk, but, as with the highs, become a bit over-bearing above half max volume. Microphonics are very minimal on these headphones which will be a plus for anyone using these while working or exercising. (And your wallet won't scream in terror at the thought of you breaking them.) Speaking of which, the M6's do a pretty good job at blocking out external noises. Further, they stay in your ears VERY will. The build quality of these is very high. They feel and look...well....amazing compared to what you would expect. The pictures do NOT do the appearance of this headset justice. They look very retro-cool, in my opinion. The number of accessories you receive with these headphones is phenomenal! (Just as a quick rundown, you get the following: 1 x black headphone case, 1 x wire wrap, 1 x airline adapter, 1 x large bi-flange earpieces, 1 x large triple-flange, 1 x small triple-flange, 1 x each of small, medium, and large single-flange earpieces; not bad for a budget headphone, eh?) As a final note in this section, these headphones are very comfortable. I can keep these in for hours on end without any ill effects. What I didn't like: As I stated in the previous section, these headphones have a very limited driver. Cranking the volume up above half max will result in exponential loss of audio quality. Details are lost, highs become harsh and nigh unbearable, bass becomes muddied, and mids start to disappear into the audio nether. (These are budget headphones...so don't expect miracles. :) ) This should be something to consider for those using these in very loud environments where you would need to turn the volume up. I generally don't like headphones with memory wires, and the M6's are no exception. I've since removed the steel wire and have found the comfort to be improved. Overall, I am very impressed with the M6's. They have exceeded my expectations in nearly every way. I would highly recommend these or any of MEElectronics products to anyone, friend or not. Which brings me to one last point I would like to make. MEElectronics customer service is excellent! When I received my pair of M6's, I noticed that my bi-flange earpieces were damaged. I e-mailed MEElectronics and received a response within 6 hours. Three days later, I received, a very well packed, set of replacement earpieces. (Thanks again, Simon!) So, on the whole, my experience with MEElectronics has been a very pleasant one. I believe the great sith lord Darth Vader expressed my feelings most aptly when he said, "Impressive...most impressive."
