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.

Audio Technica AD 700s seem like they'd fit what you need.

For the mic, if you want a desktop mic (which is preferrable) then just get one from Logitech. It shouldn't cost any more than $25. If you want a clip on mic then go with the Zalman ZM-Mic 1. The problem with clip ons is that they usually don't fit properly and can break really easily.
