Internal IR Proximity Sensor PCB
The auto-pause feature relies on an infrared transduction loop; if the IR emitter or photodiode on the internal PCB fails due to moisture-induced corrosion or semiconductor degradation, the headset cannot register a change in proximity. This specific PCB is the dedicated sub-assembly for wear detection, and replacing it restores the optical sensing path and communication with the main logic board. It is the most granular sellable component that addresses the hardware failure of the proximity detection system.
