7. Solució De Problemes
If you encounter any issues with your Monster Champion Wireless Earbuds, please refer to the following common solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| Els auriculars no es carreguen | Protective film on contacts; improper seating; dirty contacts; faulty cable/charger. | Ensure protective film is removed. Re-seat earbuds firmly in case. Clean charging contacts on earbuds and case. Try a different Type-C cable and power adapter. |
| Només funciona un auricular | Improper pairing; one earbud not charged. | Place both earbuds back in the case, then remove them together to re-establish connection. Ensure both earbuds are fully charged. Try resetting the earbuds (refer to manual for specific reset instructions if available, or forget device on phone and re-pair). |

Turn Bluetooth off and on again on your device. Move closer to your device and away from other wireless devices. |
