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.
cause it’s cool and I like it, which should be reason enough. more practically it works for cases when you lose your remote, maybe cases where you want to change the channel on some TV in a pub somewhere, shit like that. it’s fun.
