4. Maintenance
4.1 Cleaning and Care
To ensure longevity and optimal performance of your Niderson YU8 earbuds:
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Avoid using abrasive materials, solvents, or chemical cleaners.
- Ensure the charging contacts on both the earbuds and the case are clean and free of debris.
4.2 Water Resistance (IPX7)
The earbuds are IPX7 waterproof, meaning they can withstand immersion in water up to 1 meter for 30 minutes. This makes them resistant to sweat and rain.

Important: The charging case is NOT waterproof. Do not expose the charging case to water or moisture.
5. Troubleshooting
5.1 Common Issues and Solutions
- Earbuds not pairing:
Ensure both earbuds are in the charging case and fully charged. Open the case to activate pairing mode. On your device, forget the "YU8" Bluetooth connection and try pairing again. - Only one earbud working:
Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often resets the connection between the two earbuds. If the issue persists, try resetting the earbuds (refer to the full user manual for specific reset instructions if available). - No sound or low volume:
Check the volume level on both your connected device and the earbuds (via the touch screen). Ensure the earbuds are properly seated in your ears. - Charging case not charging:
Verify the USB-C cable is securely connected to both the case and the power source. Try a different USB-C cable or power adapter.
5.2 Finding Lost Earbuds
The charging case features an earbud-finding function. If you misplace an earbud, you can activate this function from the touch screen to make the earbud emit a beeping sound, helping you locate it.
