I auditioned the DT990 600ohm recently, in my search for a bassy headphone for electronic music (trance, house, drum & bass, etc). I decided it did not have enough bass and have since purchased the Ultrasone Pro 900 and am loving it. I'm sure I am one of the few who would want more bass than the 990s can offer though. Other than that, I thought they were great, although sibilant at times.
