Out of ear detection is my biggest gripe. If I take them out quick and place them on a table because I don’t have the case handy, they try to reconnect when I’m receiving a call or using audio in any way without them. I have to look for the icon in control center and manually remove them. It’s incredibly annoying.
I also noticed the membrane sounds like it’s getting blown out when they attempt to deal with loud noises in the environment.
