2. Connect the other end of the USB cable to a standard USB charger (e.g., wall adapter, computer USB port).
3. The LED indicator will show a red light during charging.
4. Once fully charged (approximately 1-2 hours), the LED indicator will turn blue.
5. Disconnect the charging cable.

Note: It is recommended to turn off the headset before charging for safety. And make sure the earphone is fully charged before its initial use.

2. Selecting Ear Tips and Ear Hooks

For optimal sound quality, comfort, and secure fit, choose the ear tips and ear hooks that best suit your ears.
