The price range...
It can't be more than 250, unless it was shipping costs or tax, that's ok.
I plan to use them only for gaming, not really for outside use, but if the audio is that good for me I might use it for music. I listen to a lot of different music, like dubstep, rap, and rock. I listen to those the most. I would like them closed, if possible.
I love headphones with a lot of bass, so that's something I'd like.
I don't really care about the mic, as long as it's not too cheap and not too big, and pretty affordable.
