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.
Why of course that is why OP only buys the finest MONSTER Vibranium-Plated Unobtanium-Engraved Analog Audiophile Cables.
