The second: Precautions for charging sports Bluetooth headsets

1. When charging, insert all the plugs in, don't just insert more than half, as this will damage the machine for a long time. When plugging and unplugging the charging plug, be lighter, otherwise, the plug will become loose after a long time.

2. Choose a suitable charger. Generally, sports Bluetooth headsets have dedicated chargers. If there is no dedicated charger, you can find a charger with the same charging interface and the same rated output power.

3. If the sports Bluetooth headset is plugged into the base or charging box for charging, it will take longer to charge after the charging is completed than directly charging the Bluetooth headset. The charging method is the same as charging the earphone directly, just align the charging cable with the hole in the base and insert it.

4. When charging the sports Bluetooth headset, try not to use the headset again to avoid accidental damage.

5. After charging and powering up, the red indicator light will light up, indicating that it is charging. If charging is complete, the indicator light will turn blue, and the charger can be removed at this time.
