I agree. Faux atmos on stereo speakers/headphones just sounds weird. It doesn't work at all. Some people seem to love it - some people maybe get the pyscho acoustic effect more than me (for me it's non existant really. it just sounds like weird wide stereo)Although I use Apple Music, Apple devices across the board and AirPods Pro 2 & Max, I have Atmos disabled on everything. It seems to take the 'oomph' out of so many tracks, especially bass-heavy stuff. I found plenty of examples where a song sounded weak and in desperate need of more volume (at max), but with Atmos off, had sufficient volume and the bass thumped like thunder. Especially on AirPods Pro 2.
Dunno why, but for me, Atmos takes the life out of so much of my music.
However on an actual Dolby Atmos speaker set it sounds amazing (on some tracks of course, they've still got to do it properly) the sub doing the kick properly stuff floating around and behind you, it's amazing. I've heard of the best versions of my favourite records that way - but they sound horrible in headphones.
