Dermatitis from AirPods Max ear cushions.
This only happens with the stock ear cushions from apple.
I have tried a number of replacements, and even silicon covers for the ear cushions. These all fix the problem.
Apple should really address this. All the alternative ear cushions are cheap quality and made from PU leather. But I can't wear the stock cushions for more than 30 min without my ears getting itchy. Prolonged use causes the skin on my ears to flake off.
