Pros: Sound Quality, Price, Build Quality.
Cons: Comfort, Wires sticking out, and Headband
My first cans, at $185 was a pretty good steal considering they weren't even on sale. After comparing them to my $20 Sony earbuds, they sound amazing! I mostly listen to EDM with a lot of dubstep and trance, with specific songs with female vocals and they are amazing. Just the right amount of bass and I can't really tell that these are revealing. The headphone didn't feel heavy in the hands but after extended use on the head, the weight it noticeable, so noticeable in fact that I am going to mod it with a new headband, removing the rubber piece and replacing it with an aftermarket one.
