With 7.1 surround sound in your gaming headset, you'll experience direction, depth, and distance when listening to your games. This is especially useful when playing online games, so you're already tracking your opponents before you see them. It also makes games like Halo a lot more cinematic, as the Halo choir will resonate around you realistically. Surround sound headsets are available in true surround sound and virtual surround sound, with virtual surround sound being controlled by software.
