I got an audio Technica ath-a900x just under a month ago.
They are really good, surprisingly much lighter than they look.
Music wise I listen to a range of music and it holds up well in all of them.
They are also comfortable. I wore them all day watching e3. Only removing them for food or going to the loo.
They work well with Razer surround as well, which I use when I game.
They go for about 170 on eBay.
