Issues with my AirPods Max 1:

* occasional deafening screatch when there's too much moisture. I'm surprised they didn't need to recall them over that

* occasional reboots when you move it a bit on your head.

Unfortunately in apple-manner they don't mention if such issues were resolved with this v2

The screech is produced by feedback in the noise canceling I think, happens if you lay on a pillow at the wrong angle also, never had it due to moisture myself.
