6. Troubleshooting
If you encounter any issues with your Jesebang S75 earbuds, please refer to the following common solutions:
| Problem | Solution |
|---|---|
| Earbuds not pairing | Ensure earbuds are charged. Turn off and on your device's Bluetooth. Forget "S75" in your device's Bluetooth settings and re-pair. |
| Only one earbud working | Place both earbuds back in the charging case, close the lid, wait a few seconds, then open the lid again. This should reset the connection between them. |
| Low volume or poor sound quality | Adjust volume on both your device and earbuds. Ensure earplugs are correctly sized and seated in your ear canal. Clean any debris from the earbud speakers. |
| Charging case not charging | Check the USB-C cable and power adapter. Ensure the charging port is clean and free of debris. |
