A:Answer As of February 2018: If replacement ear pads are available for the Sony WH-1000XM2 headphones, I haven't been able to find them, and I've seriously looked. Love is a strong word, but I really love these headphones and I wanted to prepare for the day when the ear pads fall apart. No luck. Sony Parts doesn't even list them, and the third-party sites that specialize in replacement parts for headphones don't have them either, although they seem to have plenty for other brands. I did find a page describing how to remove the existing ear pads, but it was in an article on how to put ear pads from a different manufacturer's headphones onto the Sony headphones (it involved lots of cutting and gluing, which wasn't what I was interested in).
Anyway, I'm carefully cleaning my ear pads with Armor All (frequently), fiercely guarding them from The Cat, and looking to the day that I'll have to do that cutting and gluing.
