The Steelseries 7H get my vote. http://www.amazon.it/SteelSeries-7H-...716658&sr=8-15 -- Great sound quality (on par with dedicated headphones ((headset haters can shove it))), a good quality, easily stowed mic, and they don't cost an arm and a leg.
The Corsair Vengeance are also fantastic. http://www.amazon.it/Corsair-CA-9011...6716778&sr=1-8 -- I got my wife the wireless version of these for Christmas, and they're extremely comfortable and sound great.
