Very nice headphones, but...
The biggest thing people seem to knock these 'phones for is "lack of bass." I wouldn't say they have a lack of bass, the bass is just more balanced with the mids and can sometimes be drown out by the highs.
Beautiful, crisp highs, well defined mids, fairly large sound-stage; Great for listening to acoustic guitar, vocally driven music, or anything with precise instrumentation; Pretty good fit and finish.
They aren't as comfortable as they could be, that's where they loose one egg. They want to sit on my head (which is probably larger than most; I wear a 60cm hat for reference) in a position that doesn't provide optimal acoustics. I find myself adjusting them fairly often.
