That seems to be the common failure mode for headphones: everything works, but you can’t wear the things!

Our daughter had developed ears with black flecks from her favorite headphones as the cushions shed their thin plastic coating. I’ve suggested that she sew up cloth cushions to no avail.

I did a similar job on a foam sheet and came up with headphone pads for the ancient Sennheisers. Those ones we used to get in the 70′s.. 1000 ohms and 50mW to pain threshold. They had colorful cushions that would slowly break off.
