Troubleshooting
Common Issues and Solutions
- Earbuds not pairing: Ensure both earbuds are in the charging case, close the lid, then open it again to activate pairing mode. Check your device's Bluetooth settings and try reconnecting.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. This often resets the connection and allows both to pair.
- Low volume or poor sound quality: Ensure earbuds are fully charged. Try different sized ear tips for a better seal in your ear. Clean any debris from the earbud speakers.
- Earbuds not charging: Check if the USB-C cable is securely connected to both the case and the power source. Ensure the charging contacts on the earbuds and inside the case are clean and free of obstructions.
