- For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
- Gently clean the ear tips and speaker mesh to remove earwax or debris.
Storage
When not in use, store the earbuds in their charging case to protect them from dust, damage, and to keep them charged.
Water Resistance
The KD-780 earbuds are water-resistant, making them suitable for sports and light exposure to moisture. However, they are not waterproof. Do not submerge them in water or expose them to heavy rain or sweat for extended periods. Ensure the earbuds are dry before placing them back in the charging case to prevent damage.
Troubleshooting
If you encounter any issues with your KD-780 earbuds, please refer to the following common solutions:
- Earbuds not pairing: Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to reset. Delete "KD-780" from your device's Bluetooth list and try pairing again.
- Only one earbud working: Ensure both earbuds are charged. Try placing both back in the case, closing the lid, and then reopening it. Re-pair if necessary.
- No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device. Try playing audio from a different application or device.
- Charging issues: Ensure the USB cable is securely connected to both the case and the power source. Try a different USB cable or power adapter. Clean the charging contacts on the earbuds and inside the case.
- Poor sound quality: Ensure the earbuds are properly seated in your ears. Try cleaning the speaker mesh. Move closer to your connected device to avoid interference.
