Situational Awareness & Directional Sound
The open-ear design and directional sound field technology allow you to stay aware of your surroundings while enjoying your music. This design also helps reduce sound leakage, improving privacy during calls and listening.

Situational Awareness for various activities
Maintenance
- Cleaning: Use a soft, dry, lint-free cloth to clean the earphones and charging case. Do not use harsh chemicals or abrasive materials.
- Storage: When not in use, store the earphones in their charging case to protect them and keep them charged.
- Water Resistance: The earphones are waterproof. However, avoid prolonged exposure to water or submersion. Ensure they are dry before placing them back in the charging case.
- Avoid Extreme Temperatures: Do not expose the earphones or charging case to extreme temperatures (hot or cold) as this can damage the battery and internal components.
Troubleshooting
- Earphones not pairing: Ensure both earphones are in the charging case, open the lid, and check if they enter pairing mode. Make sure Bluetooth is enabled on your device and try re-pairing.
- Only one earphone working: Place both earphones back into the charging case, close the lid, wait a few seconds, then open it again. This often resets the connection between the two earbuds.
- No sound: Check the volume level on both your device and the earphones. Ensure the earphones are properly connected to your device.
- Charging issues: Verify the Type-C cable is securely connected to both the charging case and the power source. Try a different charging cable or power adapter.
- Poor call quality: Ensure the earphones are within Bluetooth range of your device. Avoid using them in extremely noisy environments if possible, although ENC helps significantly.
User Tips
- For optimal sound quality and comfort, ensure the ear hooks are positioned correctly over your ears.
- Regularly clean the charging contacts on both the earphones and the case to ensure reliable charging.
- Keep your device's Bluetooth settings easily accessible for quick connection management.
