To begin with, I don't know much about headphones. But I'm looking for new headphones I previously had beats. Tired of them and want something new and better quality, with noise cancellation and very little or no sound leakage. Quiet the opposite from the beats, haha.
I listen to Pop,Hip-hop,rap and dance. So I want a good amount of bass, but not too much like the beats.
Budget would be around $300-350, if they are really good could go up a little more :)
