i have a set of thease.. 8 speakers for true 5.1, hooks to usb for power and your regular speaker outputs for sound. also has adaptors so you can leave your speakers hooked up with the headset plugged in at the same time.. i game and listin to music a lot. i can hear people comeing up behind me in black ops and shoot them before i get knifed.
in music, they have great sound. nice high's and very good lows. and you can adjust the output of the low drivers to suite your bass needs. you can also adjust the surround, front, and center channels.. i got mine for 60.00. the website says worth 99.. i think they should be worth more than that.
