Back in the mid 90's Sennheiser introduced a device that fooled your ear into thinking it was listening to Dolby Surround Sound Pro Logic through your headphones. The Sennheiser DSP PRO:
I still have this thing and haven't used it since home theater went digital, around 1999?. But if the Vision Pro were to incorporate some of this tech into their headset, the surround sound virtualization in headphones tech, Apple would probably sell a lot more headsets to HT enthusiasts like me.
I watch all movies using a projector and a 7.1 surround sound setup in my cave. 2D does 7.1 and Atmos 7.1 no problem. But 3D is regulated to Dolby Digital 5.1, which still isn't bad and if incorporated in this headset Apple would probably sell a lot more.
You guys are probably giggling at this thing. For it's time it was a life saver. Our infant daughter would be asleep around 8:00 PM and my wife and I would plug in two sets of headphones, sit next to each other, and enjoy movies in surround sound on our standard definition Mitsubishi 36" TV.
