Pros: Great sound, 7.1 surround works well, very comfortable, excellent customer service
Cons: issues with cable coming loose, inline volume control gets hot
After about 3 months of use, the left speaker started acting up, cutting out and buzzing. I traced the problem to where the cable coming out of the volume control on the headset side. When I manipulated it, I could hear popping and the sound would sometimes come back. I emailed Corsair, and within 24 hours, I had an RMA number, despite no longer having the UPC or packaging. They never even asked. Their RMA center is in Southern California, as am I, so it didn't take long for it to get there, and they immediately sent me a brand new unit, still sealed in packaging. I've never had such a good RMA experience. I just ordered their M90 mouse after my Razer Imperator died, and thanks to this experience, I'm confident that if I have any problems, they'll take care of me.
Overall, the headset is a great buy at $99. Corsair's customer service alone makes it worth the purchase. While it doesn't have the sound quality of Grado or Sennheiser headphones, it's got a mic and is very, very comfortable.
