Earbud batteries

iFixit reports that prying an earbud open is likely destructive and its internal batteries are soldered. The charging case is also epoxy-sealed around its battery and USB-C port.

Two versions

Standard and ANC AirPods 4 have different cases and model numbers. The ANC case adds wireless charging and a speaker; a replacement case must match the version.
