had a pair of these for a while :D and whilst they lack a bit in the bass department the soundstaging is really superb,only bettered by a pair of (heavily modified) audio technica f3s, i use these phones for FPS gaming and when im going to be wearing some phones for a long time..these are very comfortable and you can wear them for hours without fatigue....instruments are very well defined on the soundstage..which seems to expand in a deep level plain well beyond the edge of each driver ...very nice :D a bit of EQ helps them no end....but even a 10db bass boost wont make up for the lack of bass in these phones...all in all a nice phone!

First the good news: they have extended bass and enhanced treble in a way that makes them pretty nice background-music phones: I can turn the volume down very low and still get enough beats and enough highs to enjoy the music, instead of having it turn into quiet mush. That's sort of a nice feature.

The first item of bad news is that although they provide isolation for the listener, they are nonetheless leaky enough to be distracting to people nearby. They definitely don't pass the spouse-trying-to-read-a-book-in-the-same-room test. I can't recommend them for use in an open office setting, library, etc.

The other piece of bad news is that the sound quality overall is not very good. Much of the range is poorly rendered, and the midrange is especially disappointing. Amplification does not help -- if anything, it only reveals the plainness of this headphone more starkly, like shining a bright light on a bad coat of paint.

I rated them below average for comfort because they have pretty small earcups. My ears fit, but barely. If you have large ears they'd probably be uncomfortable, but if you have small ears, you'd probably have no issue with them.
