With completely wireless earbuds, the rule is: when the battery fails, they have to be disposed of. Not so with the Fairbuds, that allow you to replace batteries in just a few seconds. Combined with a repairable design, the earbuds should therefore have an extremely long lifetime.
I think JBL and some other brands do carry such earbuds, but maybe it might not be thz kind of wire you’d fancy. There are also cheaper options that have a wire linking the two ear buds, but as I said those are usually cheap and might not be up to your standards.
