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’m sorry, i’m replying to your reply, about replying to the wrong part of my reply. I put this as delicately as possible so it didn’t sound aggressive. Sorry.
