Pads started peeling and shedding plastic everywhere. We didn't want to get replacements so I peeled off all the plastic, kept the cushions and used an old jean with some wool to make it better than it was before.
I have 25 year old Grados that still have their original pads. I don't know why AKG couldn't even stand 4 years of occasional use 🤷
my favorites, grados, are on ear. These are never used outside, so isolation isn't a necessity.
If you need isolation, jeans wouldn't be the best choice i assume.
