6. Troubleshooting
If you encounter issues with your ZYHKON SU9 Sleep Earbuds, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing | Low battery, out of range, pairing mode not active, previous connection issue. | Ensure earbuds are charged. Place them in the case, close, then open to re-enter pairing mode. Move closer to your device. Forget "SU9" in your device's Bluetooth settings and try pairing again. |
| No sound or low volume | Volume too low on earbuds/device, improper fit, earbud obstruction. | Increase volume on both earbuds and connected device. Adjust earbuds for a secure fit. Clean ear tips and earbud mesh. |
| Intermittent connection/audio dropouts | Interference, distance from device, low battery. | Move closer to your connected device. Avoid areas with strong Wi-Fi or other Bluetooth signals. Ensure earbuds are fully charged. |
| Charging case touchscreen unresponsive | Low battery, temporary software glitch. | Charge the case. Perform a soft reset by holding the power button (if available) or allowing the battery to fully drain and then recharging. |
