My AirPods Pro 2 have been disconnecting randomly for the last few months too. I’ve tried turning off Noise Cancellation, Transparency Mode, Spatial Audio, Automatic Ear Detection, & Follow iPhone; I’ve tried “Forget This Device” and several factory resets to no avail.
I’ve also noticed that when I take my AirPods Pro 2 out of the case, they frequently struggle to connect to my iPhone 14 Pro. It’s something to do with the Bluetooth. They try to make the connection, but when I open up Settings > Bluetooth > My Devices, the little “Connecting…” progress circle that appears next to my APP2s gets stuck in a loop, and won’t connect until I toggle Bluetooth off & back on again then manually select my APP2s from my list of Bluetooth devices.
My 1st gen AirPods Pro were always able to connect without a hitch the moment I’d open up the charging case. Idk what the issue is here, but I’ve heard there that Apple is rolling out a Firmware Update for AirPods at some point in the near future. I sure hope it patches up this insanely aggravating bug.
