Maintenance
- Cleaning: Regularly wipe the earphones and charging case with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Water Resistance: The earphones are IPX4 waterproof, meaning they are resistant to sweat and light splashes. Do not submerge them in water or expose them to heavy rain. Ensure they are dry before placing them back in the charging case.
- Storage: Store the earphones in their charging case when not in use to protect them from dust and damage. Keep them in a cool, dry place away from extreme temperatures.

Troubleshooting
- Earphones not pairing: Ensure both earphones are fully charged. Place them back in the case, close it, then open it again to re-enter pairing mode. Make sure Bluetooth is enabled on your device and try searching again.
- Only one earphone working: Try resetting the earphones. Place both earphones in the charging case, then remove them. If the issue persists, try re-pairing them with your device.
- 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 that the charging cable is securely connected to both the case and the power source. Try using a different charging cable or adapter. Ensure the charging contacts on the earphones and inside the case are clean and free of debris.
- Sound leakage: While the open-ear design inherently allows some sound to be heard by others, the Z66 features directional sound transmission to minimize this. Ensure the earphones are positioned correctly on your ears.
