I use Logitech X-540 mostly. I don't like headphones for gaming and I do like real 5.1 with positional sound. Then again, I haven't tried any 5.1 headsets and having the mic built in might be cool.

Looks like it's pretty close anyway.

edit: I also have a decent hifi for home cinema but since my TV bit the bullet recently I don't use it much - just for music when I want it loud.
