I've had good experiences with Razer headsets so far. My first was the Razer Piranha and I'm currently rocking Tiamat 7.1's. The only issue I have with the Tiamat is the feedback you get when plugging the USB power cable into your computer. Apparently this is due to a case which isn't properly grounded. My solution at the moment is to use a powered USB hub. Does anyone have another solution?
