6. Troubleshooting
- Earphones not turning on: Ensure the earphones are fully charged.
- Cannot pair with device: Make sure Bluetooth is enabled on your device and the earphones are in pairing mode (flashing indicator light). Try restarting both the earphones and your device.
- No sound or poor sound quality: Check the volume level on both the earphones and your connected device. Ensure the earbud attachments are securely inserted. If using bone conduction, ensure they are positioned correctly on your cheekbones.
- Intermittent connection: Ensure your device is within the 10m wireless range and there are no significant obstructions.
- Call noise reduction not working: Ensure the microphones are not obstructed. The 2Mic ENC algorithm is designed to filter background noise during calls.

- Secure fit for sports: The ergonomic design and flexible ear wings ensure a stable fit during intense activities. Adjust the neckband for optimal comfort and security.
- Voice Assistant: Utilize the Apple Siri Support feature for hands-free control and convenience.
