AirPod Pro
Linked to 13 ProMax, iPad Pro 11, MBP
Updated pretty quickly by …. Chuckle
Immediate noticeable changes for me - Used Purple Hat, My Universe, and a mix of others.
1. Went from Spatial Fixed to Spatial Head Tracked on update
2. Bass is noticeably heavier
3. The highs, especially voice and string sounds muffled, or more muffled.
4. They connect quicker
5. I’ll see how they do tomorrow when using for calls (Cell vs Teams Calls)
One possible bug.
When I open the case to connect to my any of my devices, my wife’s Mini 6 gets the “Not your …” AirPods Pro on her device. These have only been linked to mine. Happens pretty much any time I open the case to connect. Yep, she’s annoyed

I’m on 15.5 b4 and she’s on 15.4.1. Might have something to do with the quicker connect? I’m guessing.
