The Cougar Immersa Pro offers virtual 7.1 sound when plugged in via USB to a machine with the driver installed, you will only hear stereo from the 50mm drivers if plugged into an audio jack.  On the other hand plugging it into the audio jack also disables the RGB features on the headset, if you don't feel like forcing the driver to disable them.  The Guru of 3D appreciated the comfort of the earcups as well as the overall quality of sound but felt somewhat let down by the quality of the microphone; a common complaint on gaming headsets.

"They recently sent us a box full of goodies, including the new Immersa Pro, their top headset. If you thought you’d forgotten about RGB all the things, well, Cougar is here to remind you with the Immersa Pro."
