Well I've been using them for a little more than a week and I have to say I really love them. Sound quality is amazing, and they are really comfortable. The only thing is, as ozzy said, if you have the volume up high, people around you can hear your music. If I'm in a quiet place, I've just been keeping the volume pretty low and it has been fine. They are pretty awesome, so unless you really need noise-canceling or can't have people around you hear your music when it's loud, I would highly recommend them.
