QuietComfort Earbuds II Charging Case
The alternating red and white LED sequence is the visual output of a firmware 'kernel panic' or a hardware-level communication failure within the charging case logic board. This occurs when the microcontroller cannot verify the state of charge or the identity of the inserted earbuds via the pogo-pin interface. Replacing the case provides a new logic controller and BMS, clearing the persistent hardware lockout.
