Maintenance

Troubleshooting
- Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Check your device's Bluetooth settings and try re-pairing. If issues persist, perform a factory reset (refer to the app or manufacturer's support for specific steps).
- No sound or low volume: Check the volume levels on both your device and the earbuds. Ensure the earbuds are properly seated in your ears. Try disconnecting and reconnecting the Bluetooth connection.
- ANC not effective: Ensure the earbuds are properly sealed in your ear canals. ANC performance can vary based on the type and frequency of ambient noise.
- Earbuds not disconnecting/shutting off automatically: If earbuds do not automatically disconnect when placed in the case, ensure the case is charged and the earbuds are correctly seated. Manually disconnect via your device's Bluetooth settings if necessary.
- Touch controls unresponsive: Ensure your fingers are clean and dry. Try restarting the earbuds by placing them in the case and taking them out again.
- Battery life shorter than expected: Ensure earbuds and case are fully charged. High volume levels and continuous ANC use can reduce battery life.
