Maintenance
Cleaning
Regular cleaning helps maintain sound quality and hygiene. Use a soft, dry, lint-free cloth to wipe the earbuds and charging case. For stubborn dirt, slightly dampen the cloth with water. Do not use abrasive materials or harsh chemicals.
Storage
When not in use, store the earbuds in their charging case to protect them from dust, moisture, and physical damage. Store the case in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
If you encounter any issues with your yobola Wireless Earbuds, refer to the following common troubleshooting steps:
- Earbuds not pairing: Ensure both earbuds are charged and removed from the case. Turn off and on your device's Bluetooth. Forget "T9" from your device's Bluetooth list and attempt to re-pair.
- Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open the lid and remove them. This often re-syncs them.
- No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device via Bluetooth.
- Charging issues: Verify the USB-C cable is securely connected to both the case and the power source. Try a different USB-C cable or power adapter.
