Important: If the LED light doesn't light up while charging, please take the following steps:
1) Clean the charging port and the charging cable "head" with a small soft brush to remove debris.
2) Try to charge your earphones for at least 1 hour with:
- another charging cable
- another power source
- another adaptor (if any).
If the issue was resolved with another charging cable, please check 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 earphones are more than 1 year old, their battery life may be reduced due to the natural lifecycle of the Li-ion battery.
