Troubleshooting
If you encounter issues with your StreamBuds Custom 3, try the following solutions:
| Problem | Solution |
|---|---|
| Earbuds not pairing | Ensure earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode. Forget the device in your phone's Bluetooth settings and try pairing again. |
| Only one earbud working | Place both earbuds back in the charging case, close the lid, wait a few seconds, then open it again. This often re-syncs them. Check battery levels for both earbuds. |
| No sound or low volume | Check the volume on your connected device. Ensure earbuds are properly seated in your ears. Clean any debris from the earbud speakers. |
| Charging case not charging | Ensure the USB cable is securely connected to both the case and the power source. Try a different USB cable or power adapter. |
