Installation Notes
Advanced difficulty. No soldering required. The charger case battery connects by a plug; disconnect the old cell, seat the new one, and reseal the case. Each earbud is glued shut and must be carefully heated and pried open to reach the coin battery, then resealed with the included RTV glue. This is delicate work best suited to an experienced technician. Confirm your case is model YY2948 before ordering.
