I can hear "hiss" when listenning to Judy Colins, Mary Black, Pet Shop Boys and Clanned, it is quite annoying. I don't have problem when listenning to Crystal Method, Chemical Brothers and Eurythmics; the bass is indeed quite good. Not try Classical yet. For two days, I'd say it is more for pop, with mid-low bass; I think it is plenty bass, but not as deep (or tight). Overall, fun, like Koss and Sony (they all colored music, but not stretch too far), ; I don't rate Headbanger higher, but you like clean bass and don't mind "hiss", it is a good choice.
