Hey there Hi Yargu,
One last item to test out. We'd like you to check this out: Control Spatial Audio and head tracking. We'd want to see if Spacial Audio had been activated. You can check this setting:
- "Wear your AirPods, and make sure they’re connected to your device.
- On your iPhone or iPad, go to Settings
> Bluetooth. - In the list of devices, tap
next to your AirPods, then tap Spatial Audio."
We've found this in the guide that has been provided. The reason why we're asking is because you might be going to a site that has Spacial Audio (Apple Music) to a site that doesn't. The rule generally is that the settings remain the same, but it might take a moment to adjust if this feature isn't available on the site. If it's been enabled, disable it then test it out.
If this is not enabled, and you still notice that adjustment, you'd want to contact Apple Support. They can work further with you to see why this is happening.
Kind regards.
