What's your price range?
Currently I am using Steeleseries Siberia V2
http://www.ncix.com/products/?sku=45...re=Steelseries
Very comfy and sound quality is decent.
If you have the money I suggest getting Steelseries 7H
http://www.ncix.com/products/?sku=54...re=Steelseries
is about 120 dollars
If your budget is high I would suggest Sennheiser PC350

However as some ppl suggest to get the true quality of Sennheiser PC350 you need more than just a sound card (something like a whole stero system setup).
I wouldn't suggest getting anything with razer.I have their keyboard and mouse and is pretty bad. The keyboard's back light would turn off on its own randomly sometimes when I am play WoW it would be crazy where I can't control it. Got their wirless mouse and after 2 days it stop working like the button would not respond. Got a new one from NCIX as replacement and it broke within a week and finally got the MX518.
