Maintenance
1. Cleaning
Regularly clean your earbuds and charging case to ensure optimal performance and hygiene. Use a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents. For ear tips, remove them and clean with a damp cloth, then dry thoroughly before reattaching.

3. Storage
When not in use, store the earbuds in their charging case to protect them from dust and damage. Store in a cool, dry place away from extreme temperatures.
Troubleshooting
If you encounter any issues with your earbuds, please refer to the following common solutions:
- Earbuds not pairing:
Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode. Delete the earbuds from your device's Bluetooth list and try pairing again. - No sound from one or both earbuds:
Check the volume level on your device and the earbuds. Ensure the earbuds are properly connected to your device. Try restarting your device and re-pairing the earbuds. - Cannot answer calls:
Ensure the earbuds are connected to your phone. A single tap on either earbud should answer an incoming call. Refer to the 'Touch Controls' section for detailed instructions. - Charging issues:
Verify that the Type-C charging cable is securely connected to both the charging case and the power source. Try using a different charging cable or power adapter. Ensure the charging contacts on the earbuds and inside the case are clean. - Poor sound quality:
Ensure the earbuds are properly seated in your ears. Try different sized ear tips for a better seal. Move closer to your connected device to avoid interference.
