6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing with device | Bluetooth off, earbuds not in pairing mode, device already connected to another Bluetooth accessory. | Ensure Bluetooth is enabled on your device. Place earbuds in case, close, then open to re-enter pairing mode. Forget previous connections on your device. |
| No sound or low volume | Volume too low on device/earbuds, earbuds not properly seated, earwax blockage. | Adjust volume on both your device and the earbuds. Ensure earbuds are correctly placed in your ears. Clean ear tips and speaker mesh. |
| Earbuds not charging | Charging cable/port issue, dirty charging contacts, case battery depleted. | Check cable and power source. Clean charging contacts on earbuds and case. Ensure charging case is charged. |
