Practically, an iPhone battery is replaceable in you average mall tech shop in a mid sized town. In the 5/6 era, it was a 30 minute job if you’re being slow and careful. (I’ve got 3 screen replacements and 2 battery swaps under my belt from that era).
My understanding of the AirPods is that the complexity level is more akin to component level fixes for a main phone board. I’d expect that there are people who can do it, but they’re rare, and they’ve got specialized equipment, and it’s probably not worth it for an earphone battery.
