If there are other runners here, with enough ear sweat the AirPods starts beeping, the noise makes you want to pull the AirPods away immediately. After some cool down they start working again, though my right AirPod now starts "hissing" sooner than it beeps. This is when I run at 100+ Fahrenheit. Still a great product though.
My original AirPods started to not charge reliably. It was corrosion from the sweat from running. I now have a pair of AirPods Pro which are supposed to be sweat resistant but I’m skeptical. If I do a long run in the summer there’s a lot of sweat.
