Maintenance
Cleaning Your Earbuds
To maintain sound quality and hygiene, regularly clean your earbuds and charging case. Use a soft, dry, lint-free cloth to wipe the earbuds and charging contacts. For ear tips, you can gently remove them and clean with a mild soap solution, then rinse and dry thoroughly before reattaching.
Storage
When not in use, store your earbuds in their charging case to protect them from dust and damage. Store the case in a cool, dry place away from extreme temperatures.
Troubleshooting
Common Issues and Solutions:
- Earbuds not pairing with each other or device:
Try resetting your earbuds. Click the left and right power switch simultaneously 4 times quickly. Then attempt to pair again.
- Earbuds not charging:
Ensure the plastic film on the charging points is removed. Check if the charging case has power. If the case has no power, the earbuds will not charge automatically when placed inside. Charge the case using the provided Type-C cable.
- Low volume or poor sound quality:
Ensure the earbuds are properly seated in your ears and that the correct size ear tips are used. Clean any debris from the earbud speakers. Check your device's volume settings.
