Decided on the headphones to replace my failed 5.1 system, after checking out reviews and such, and then noticed that Amazon had them on sale for 44% off: Logitech Wireless Gaming Headset G930 With 7.1 Surround Sound.
I trust their stuff. It always lasts well. I have an old trackball I just love that is still working. Just ordered an HD webcam from them yesterday. Got tired of the weird workarounds it takes to Ustream a GoPro or DSLR.
