I’m assuming they also have some special hardware/firmware for the head tracking feature
Also, respectfully suggest that you review the HN guidelines WRT your own comment. "I have no idea what I'm talking about, but I'm going to comment anyway" is clearly covered.
1. Dolby atmos, obviously this is industry standard
2. Head tracking, where sound stays in the same direction despite movement. Introduced last year for the listed headphones, works on some video streaming services. Not supported by Apple Music yet but supposedly coming soon.
I only meant that the head tracking seems specific to apple headphones. If you still feel I’m dull please knock some sense into me.
