70% Isopropyl Alcohol Cleaning Kit
Accumulated skin oils and environmental debris create a high-resistance barrier on the copper-alloy charging pads. This prevents the low-voltage charging cycle from initiating, which the user perceives as a dead unit. Cleaning the contacts restores the electrical path required for the BMS to detect the charging case.

Momentum True Wireless 4 Replacement Left Earbud
If cleaning fails, the internal Li-ion cell has likely entered a deep-discharge state below the safety threshold (approx 2.5V). The internal protection circuit (PCM) executes a hardware lockout to mitigate fire risk, rendering the internal hardware non-functional and requiring a full bud replacement.

Momentum True Wireless 4 Charging Case
A failure of the spring-loaded pogo pin assembly within the case can prevent mechanical engagement with the earbud. If the pin is stuck in the retracted position or the internal ribbon cable to the pin is severed, the earbud will not receive the 5V rail required for operation.
