I’ve resoldered the batteries on my generic wireless earbuds that were very much meant not to be serviceable. It really wouldn’t be hard to make them serviceable, even if they weren’t user replaceable. There’s one in each bud, and another in the case. A battery only needs two electrical contacts on a component that is already self contained. Its a very simple device. The lithium ion ones in this size range are a few bucks each on the wholesale market. There are even standardized button cell sizes. It is very much a design choice. The other side of it is that lithium ion battery tech is at the point where the battery lifespans is starting to exceed the device lifespan. Certainly true for the cheap side of the earbud market
