Don't need anything but a USB port. I mostly use it for Skype, and it is very clear and loud enough. For gaming it is good, base is clean and the highs are crisp. Very comfortable and looks great.
Seems a little flimsy, but I have had no problems with it in the last 6 months.
Perfect for Skype, good gaming headset. The detachable mic is really great when you are just listing to music. The other people on the end of my skype calls always tell me how clear my voice is with this headset.
