The gaming headset maker ROCCAT has collaborated with its new parent, Turtle Beach, on its new Elo series. It comes in cross-platform stereo, USB and wireless varieties, all of which are rated for 7.1 surround sound. The Elos also have their brand's AIMO lighting system and self-regulating metal headbands.

I'm sorry, but if you only have 2 speakers you do NOT have 7.1 surround sound.
This marketing BS and blatant lies really pisses me off. I wish the media would grow some and call manufacturers out on this.
