Yeah, I'm not wasting my time on these things and this review...
Either my pair of
Brainwavz M4 from MP4Nation were fake/defective (in both earpieces) or other people rating these so highly have been paid! Truly, shockingly, awful.
You know when you held a seashell to your ear as a kid? That's how these things sound - all 'swirly'. It's bizarre no one's mention it and how bad they are. It's pointless me going into detail about the sound of these, using pretentious word like 'soundstage', etc. They are, across the board, worse in every sound range than the
Brainwavz M2! Why would anyone want to pay $10
more for the M4, when the
only improvement they have over the M2 is the redesigned (spinable) clothing clip!?
There's something seriously wrong with the sound of these. In music/sound editors I believe the sound effect they create is called
'Flanger'. Basically, if you've ever sat inside a huge concrete construction tube, you'll know the noise - all hollow and airy/swirly,
tubular!
Just my 2 cents on the above issue:
I just received my M4 tonight (mic version) and I immediately tried them with my S:Flo 2...well, my experience with M4 sound was all of a sudden very close to the one described above, if not worse (I would say worse, indeed).
However, it very soon turned out that there was a reason for that, and that reason lies in the particular connector (mini jack) needed for the mic version. Having to carry three signals (two audio output channels plus one voice input channel) this connector is phisically different from the standard stereo mini jack: it has three contacts + ground compared to two contacts plus ground of the standard one (you can see that by comparing it to any standard one).
While for M4 mic version universal mp3 player (thus stereo only) compatibility is claimed, it can happen that some player is not really compatible with this connector, as the contacs do not fall in the right place and do not match the internal contacs that they are supposed to match inside of the player. From this comes the distorced sound.
To check this, I tried the M4 with my smartphone, only to find that the distorced "fake" sound was gone and that the M4 where now doing the good job with the sound they are supposed to do (and I must say, I found them quite competent at that...

)
I don't know if the problem above comes from a mic equipped M4, I just wanted to share my experience with what seems a similar issue.
Hope this helps.
Just one last thing: sorry, but I have to remark that MP4Nation seem to have its fault here, as they didn't even bother to check the compatibility of the mic version M4 with their own players... tsk tsk
