Replacement Charging Case
The charging case serves as the master logic controller for the earbuds' sleep/wake states and firmware updates. Internal failure of the lithium-ion cell or the charging PCB prevents the earbuds from initiating a handshake, often resulting in connectivity loops. Because the chassis is sealed and non-serviceable, the entire assembly must be replaced if a hard reset fails to clear the logic error.

USB-C Charging Cable
Failures in power delivery often stem from internal fractures in the copper strands of the USB-C cable or debris within the connector housing. A compromised cable provides inconsistent current, which can prevent the case from reaching the threshold voltage required to trigger the earbud charging cycle.

Electronic Contact Cleaning Kit
Microscopic accumulation of skin oils and environmental contaminants on the pogo-pin interface increases contact resistance. This resistance prevents the earbud from detecting the case's presence, causing the system to remain in an active Bluetooth state, which leads to rapid battery depletion and pairing failures.
