Summary: I like the bass, I really appreciate them in rock songs as well as some hip hop. The quality is good, there is a good amount there as well. I find them very comfortable, I am very picky when it comes to comfort so it is hard to please me. Now the bad, there is not real mids nor highs. They are both very thin, and the little that is there does not have great quality. They are very laid back sounding, i would appreciate a little bit more up frontness to it.
Summary: I purchased these headphones to replace my aging (and falling apart) Bose Triports. Their primary use is for PC gaming and music listening, and they are powered by an X-fi ExtremeMusic soundcard.
When I first started listening to them I noticed right away that they were very bright - almost too much so. And despite their enormous earmuff-like girth, the bass response was a little weak.
