You only have ~2 ears, there is no need for 5.1 channel surround sound.

Hearing is more involved than taking sensory input from two sources. If it weren't, there wouldn't be mixing and mastering engineers using speakers. Which they mainly do.

  Pretty sure they use speakers because they are mastering primarily for speaker setups. Not because it increases the accuracy of location information encoded in the sound.

    Nope. Because headphones don't give you sound pressure fluctuations in your body, and because the depth (not width!) perception is all messed up when using headphones.

  Give this a go, with headphones https://www.youtube.com/watch?v=4BltHXngvlk https://www.youtube.com/watch?v=4BltHXngvlk

    Yeah, it's a lot better than without the transfer function. It just doesn't react to my head movements, which speakers do (by staying stationary relative to my head)

      Sure, but your screen doesn't move, so your head doesn't move much either.

We only have ~2 eyes, there is no need for a third dimension!

  You only need a 2D display to create fully 3d images (see the 3DS for an example).

  You meant this as a sarcastic response, but literally all VR headsets are just 2 displays, 1 per eye. The same thing is true about audio & ears. If you've got a speaker that you know is dedicated strictly to a single ear, then all you need is 2 speakers to simulate audio coming from anywhere. It's called HRTF and it's not at all a new technology. All you actually need is stereo headphones to have 3d positional audio.

Did you stop to think for two seconds before posting this? People can tell where a sound is coming from in a 3d space. That’s why you can tell the difference between a sound directly in front of you and directly behind you.

  Positional audio in video games exists and is good. Try playing Rainbow Six: Siege. With the right signal processing you only need 2 sound sources.

  You can easily create sound in front of and behind you with headphones.

    Accurate positional audio from a stereo source is far from easy.

      Try playing Rainbow Six: Siege. You can accurately shoot people through walls just by listening to their footsteps.

      It's even harder with surround setup.

  I remember being blindfolded in high school science class and testing this by having someone clap two sticks together around my head. Surprisingly difficult to tell if something is in front or behind you.
