Dust off some old stereo PC speakers you might have lying around and hook them up to your computer. Set your Windows sound to Desktop stereo speakers. Load up an online PVP shooter, set the in-game sound to stereo. Join a match and tell someone to walk behind you and shoot their gun into the air. Have them walk around you in a full 360 circle shooting their gun the whole time. I invite everyone to try this. Now, did you ever NOT hear the gun? Point taken. Not easy to be the lone dissenter in a thread as old as this one though.
