4.1 Charging the Headset

Before first use, fully charge your headset. The headset provides up to 60 hours of working time on a full charge, which typically takes 2 hours.

1. Connect the provided Type C charging cable to the charging port on the headset.
2. Connect the other end of the cable to a USB power source (e.g., computer USB port, wall adapter).
3. The LED indicator will show charging status (refer to Section 5.1 for LED indicator details).
4. Once fully charged, disconnect the charging cable.

4.2 Pairing with Devices

The LEVN CT003 headset uses Bluetooth 5.3 for a stable and efficient connection. It supports dual connection, allowing you to connect to two devices simultaneously.

1. Power On: Press and hold the Multi-Function Button (MFB) until the LED indicator flashes blue and red, indicating pairing mode.
2. Enable Bluetooth: On your device (smartphone, tablet, laptop), enable Bluetooth.
3. Select Headset: In your device's Bluetooth settings, search for and select "CT003" from the list of available devices.
4. Confirm Connection: Once connected, the LED indicator on the headset will turn solid blue. A voice prompt will confirm "Connected".
5. Dual Connection: To connect a second device, disconnect the headset from the first device (or turn off Bluetooth on the first device temporarily). Put the headset back into pairing mode (blue and red flashing LED). Connect to the second device. Then, re-enable Bluetooth on the first device, and the headset should automatically reconnect to both.

6. Maintenance and Care

• Clean the headset regularly with a soft, dry cloth.
• Avoid exposing the headset to extreme temperatures, humidity, or direct sunlight.
• Do not use abrasive cleaners or solvents.
• Store the headset in a cool, dry place when not in use.
• Avoid dropping or subjecting the headset to strong impacts.

7. Troubleshooting

If you encounter issues with your LEVN Bluetooth Headset, please refer to the following common solutions:

• Headset not powering on: Ensure the headset is fully charged. Connect it to the Type C charging cable and allow it to charge for at least 10 minutes before attempting to power on again.
• Cannot pair with device:
  • Ensure the headset is in pairing mode (LED flashing blue and red).
  • Make sure Bluetooth is enabled on your device and it is within the 15-meter range.
  • Forget the device from your Bluetooth settings and try pairing again.
  • Restart both the headset and your device.
• Poor microphone quality or background noise:
  • Ensure the microphone boom is positioned correctly, close to your mouth.
  • Verify that the AI Noise Cancellation feature is active (it is an inherent feature of the microphone).
  • Check your device's audio input settings to ensure the headset microphone is selected as the default input device.
• Audio in mono during calls/gaming: This is a limitation of Bluetooth technology when using the microphone for communication (Hands-Free Profile). To achieve stereo audio, the microphone typically needs to be inactive. If stereo audio with an active microphone is critical for your use case (e.g., gaming), consider a headset that uses a 2.4GHz wireless protocol instead of Bluetooth.
• Uncomfortable fit: Adjust the headband and rotate the earmuffs to find a comfortable fit. The headset is designed to be lightweight for extended wear.
