Just got mine too, 4 days ahead of schedule. I can't really complain -- I've listened to 2 or 3 songs so far and I like the sound and comfort so far. These are my first noise canceling headphones, so I don't have much to compare to. But the sound is as good as my regular Bose headphones and there is definitely less noise (and they were about $40 cheaper than those were).
The only thing that bothers me a little is the volume control on the cord. I just generally don't like to have it there, as they seem to break easily. But the cord is detachable, so it shouldn't be hard to replace if I need to (in fact, I suspect I could probably just use a regular stereo cord if I want).
All in all, a good purchase.
