This review shows the Sony's call quality to be pretty bad, especially in windy conditions, which is quite common here when I'm walking around. Pity.

I had no clue about this. Very useful, thank you!Any authorised Sony service agent should be able to get genuine parts for you. They're not exactly cheap, though, be warned!
Here's the battery for the XM2, for example. A set of ear pads costs about the same.

By the way, it looks like a fair price
I bought a set of these.. the bluetooth audio with drops so much with my iPhone 11 Pro Max I may end up returning them. Looks like it's a firmware issue with the headphones.. the iOS Bluetooth debugging tools constantly log the following after an audio drop. And the audio drops happen constantly..
