6. Maintenance

• Cleaning: Regularly clean the earphones and charging case with a soft, dry, lint-free cloth. Remove ear-tips and clean them with mild soap and water, ensuring they are completely dry before reattaching. Clean earwax and debris from the earphone nozzles using a small brush or cotton swab.
• Storage: When not in use, store the earphones in their charging case to protect them from dust and damage.
• Battery Care: Avoid exposing the earphones and charging case to extreme temperatures. For optimal battery longevity, avoid fully discharging the battery frequently.

7. Troubleshooting

If you encounter issues with your Moondrop Ultrasonic earphones, please refer to the following common solutions:

• No Sound: Ensure the earphones are charged, properly paired, and the volume on both the earphones and your device is turned up. Check if the correct audio output is selected on your device.
• Pairing Issues: Turn off Bluetooth on your device, then turn it back on. Try forgetting the device in your Bluetooth settings and re-pairing. Ensure the earphones are in pairing mode.
• ANC Not Working Effectively: Ensure the ear-tips provide a good seal in your ear canal. Adjust the ear-tips size if necessary. Check the Moondrop Link app to confirm ANC is enabled.
• App Connectivity Issues: Ensure your earphones are connected via Bluetooth to your device before opening the Moondrop Link app. Check for app updates.
• LDAC Not Activating: Verify that your audio source device supports LDAC. Enable LDAC within the Moondrop Link app. Some devices may require manual selection of the LDAC codec in developer options.
• Distortion at High Volume: If using custom EQ settings, especially with high gain, distortion may occur. Try reducing gain or using a default EQ preset.

For persistent issues, consult the Moondrop Link app for potential firmware updates or contact Moondrop customer support.
