Summary: I've had a variety of headsets over the years and I have to say that this one has been the best overall for me. My previous headsets included ones like Creative Labs Fatal1ty Professional Series MKII (which fell apart twice and had lousy customer support), the Corsair Vengeance 1500 (which was like wearing a giant vise on your head and almost no bass), and the Plantronics GameCom 780 (it had good sound, but was uncomfortable and cheaply made).
Summary: This is a well built headset on the high end of the mid price range. Good headsets are hard to find, especially in the mid to lower price ranges. This is worth buying if a $200 headset is not in the budget.
Pros: Comfortable; Long cord so I can plug the USB into the back of my tower and bring the cord through the back of my desk so I'm, hopefully, not tripping over it. Reasonably good sound. Works with Ventrilo and Teamspeak., the drivers appear to be solid. It seems solidly built. I especially appreciate that the wires holding the floating headband in place are twisted stainless steal.
Cons: The 7.1 surround sound is virtual, in other words it's just a processed effect. Sound quality, both for the headphones and the mic, is on the low end of fairly unspectacular.
