3D stereo headphones

using a compass to align audio in headphones according to direction faced

imagine this:

You are wearing wireless headphones that when you turn your head keep the sound of the heavy breathing in the horror movie opposite the screen wherever you look.

all you need is an electronic compass inside the headphones and a button labeled "I'm now facing front, please save this direction" and the microchip in the headphones will remix the sound thats in 5.1 surround sound (or even stereo) to make it sound like the action is facing the screen wherever you look

EDIT:

i know someone designed something like this before but this way you can cheaply get full 3d where you can still turn youre head

       Welcome [IceFest], but... Where else are you looking, when you're watching a movie?

       [+] Good idea for a video game, evesdropping on enemy conversations in a 3d environment ...adds a good tactical element.
