Black marks on white AirPods Max Headband
Strange black marks have started to show up on my headband.
It looks like the marks are coming from inside the rubber. I have tried carefully to clean them carefully with liquid laundry detergent but without any luck.
I am always treating my headphones with respect. Laying them down on the couch when not in use.
Never transported them anywhere or wearing them outside.
Do anyone know what can cause this or how to remove them?
