OK, I was kind of dubious about all the hype but these are remarkably good.
The combination between clarity and tonality is amazing. They are engaging and musical while still being very accurate. Separation and instrument placement is very good. Soundstage is pretty wide/deep.
The bass is a weakness though. For double bass in jazz its exceptionally well articulated. However for something that needs a bit more quantity, for example the huge drums in the climax of an orchestral piece, its wanting. Other bass is hit or miss. If the bass is recorded in the forefront, it can sound very good. However if its in the background it tends to get a bit lost in the music.
And the fit and isolation is really good for me. I found that I have to put the headband nearly all the way back on my head, right before it starts curving down to the neck. With that placement, isolation and comfort are great and I don't feel that the ear pieces are constantly threatening to swivel on me.
It crushes my AKG 545s (anyone want a pair?), the Soundmagic HP100s, and the Onkyo HF300s. Its right on the level of the Thinksound On1s. A little more bite then the On1s but not as good bass and lower mids. But considering price, its no contest.
