I'm very impressed, to say the least.
I got these thinking they'd be just like any other over ear's. They definitely aren't. First off, for their price, they've got some pretty intense bass, I've put them up to several tests and they performed to no fault. They have great lows, mids, and highs. They are comfortable, versatile, and durable (I've already dropped them a few times, not even a scratch on them). I compared them to a friend's pair of Skullcandy TI's and another friend's pair of GI's, gotta say these blew them away.
All in all, if you're planning on getting headphones, get these, no question.
