Is there no way to play Doom with just the earbuds? There's a mod that adds audio cues to make Doom playable for the blind: https://www.youtube.com/watch?v=vtoAo__2kYo

Adding high quality binaural audio to Doom would make this even more viable. Earbuds have accelerometers which could also be incorporated to add additional queues.
