Answer 1

Same as a FPS video game. Sounds are recorded with spatial placement information, during playback, sounds are rendered in a virtual soundstage, with transimission and transformation due to your head’s point of view factored in, then the rendered audio stream gets back in the headphones conventionally.

There are headphones with gyros inside that can transmit head movement to the renderer to simulate point of view change.
