"The Mad Catz Cyborg FREQ 5 has excellent audio quality. Its 50mm Neodymium drivers guarantee deep bass and crisp highs. Compared to competing products, there's very few that work as well as the Mad Catz FREQ 5 out of the box. Since this is a plug-and-play headset, it requires no software installations, no computer restarts, and can be carried from computer to computer easily."
