What is the difference between your standard headsets and the ones with USB?
As both types of products are identical in make and function, you will enjoy the same comfort and pinpoint sound with both of them. The difference is that the USB bundle features our very own SteelSeries USB soundcard. The SteelSeries USB Soundcard offers a consistent sound experience allowing gamers to always play with the exact same sound and settings, no matter where in the world - or at what computer they are playing.
The USB soundcard supports the following systems: Win 7/Win XP/Vista/Win 2000/Win 98/Win ME via PC drivers & Mac OS X via USB plug and play. You can download the latest PC drivers from here. Regardless of platform, the headset is fully functional when utilizing the standard audio.
