Wrong!
I had a 5.1 speaker system and surround level, yeah, it made surround effect (sorrounded), the sound almost always came from all sides, and we could never identify the source of a sound, then there, with the helmet when sound comes from behind, we really feel that it comes from behind, while maintaining a natural look when the sound comes from the front, we hear it before, etc. .
It also keeps a fairly good quality of sound. (48khz 16 bit, to be precise)
