Japanese Thanko developed a 6 speaker surround head-set. Looks definitly geeky when worn.
The THANKO 5D1 USB Headphone can be a normal stereo headphone. It can also pop-out 2 more speakers at the front and 2 more at the back. Which makes it a total of 6 speakers creating surround sound. It comes with a special remote just for the headphone with the functions of surround effect, mute, and volume.
AudioCubes sells this Super Geek Headphone for $99.00.
