Use a Type-C charger to charge the charging case, or place the charging box light up on a compatible wireless charger. The red indicator light flashes during charging, and the white indicator light turns off after charging for 10 seconds.

Checking the Battery Level of the Earphones
After connecting the earphones to a phone, you can check the earphones’ battery level on the phone’s status bar.

Checking the Battery Level of the Charging Case
Open the charging case’s lid, or press the function button if the lid is closed:
- When the indicator light of the charging case stays lit for 5 seconds, it means the battery is sufficient.
- When the charging case’s indicator light is blinking, it means the battery level is low and should be charged immediately.

Connection Interrupted
When a device’s Bluetooth is disabled, or if the earphones are out of range, the earphones will automatically enter awaiting connection mode. If the earphones remain disconnected to a device for 5 minutes, they will enter sleep mode. Wearing the earphones again will wake them up and enter awaiting connection mode.
Automatic Connection
While the earphones are in the charging case, opening the case will cause the earphones to automatically connect to the most recently used Bluetooth device. If no connection history is detected, or if the earphones cannot successfully connect to any Bluetooth device, the earphones will automatically enter the awaiting connection mode.
Note: If the earphones cannot automatically connect to a device, you will need to manually connect the earphones to the desired device via the device’s Bluetooth settings.

Due to the connection characteristics of the Bluetooth signal, in dense environments with 2.4 GHz electromagnetic signal interferences, there may be occasional disconnects or no sound.
