Important: If the LED doesn't flash red while charging, please follow the troubleshooting steps below:
1) Clean the charging port and the charging cable "head" with a small soft brush to remove debris.
2) Try to charge your headset for at least 4 hours with:
- another charging cable;
- another power source;
- another adaptor (if any).
3) Check if the headset works via LINE-IN mode.
If the issue was resolved with charging cable, please check another section "Defective charging cable".
Note 1: High humidity and extreme temperatures can cause the deformation of the device and affect battery performance.
Note 2: If your headset is more than 1 year old, their battery life may be reduced due to the natural lifecycle of the Li-ion battery.
