iPhone 13 Pro. 17.3
If I play "Love me two times" by the doors, or Money by Pink Floyd or say Bohemian Rhapsody - all classic songs that play around with Left and Right channels in the mix- on my airpods I get no seperation of the music. If I use a lightning to 3.5mm adapter with proper headohones - the same. 

The same happens if I turn off dolby atmos. What the heck is iOS doing? How do I turn this off?
