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.
Sorry, what? They are obliged to buy them, if not today, they will be when their phone stops working and they have to buy a new one, because that won’t have a jack connector.
Except of course if they don’t use a smartphone.
