Maintenance
Cleaning
- Regularly clean the earbuds, especially the ear tips and charging contacts, with a soft, dry, lint-free cloth.
- Do not use abrasive cleaners, alcohol, or chemical sprays.
- Remove ear tips and clean them separately with mild soap and water if necessary, ensuring they are completely dry before reattaching.
Water Resistance (IPX5)
The LENCENT headphones are IPX5 water-resistant, meaning they are protected against low-pressure water jets from any direction. This makes them suitable for workouts and light rain.
Figure 6: The IPX5 rating provides protection against sweat and splashes, ideal for sports and outdoor activities.
Important: IPX5 rating does not mean the headphones are waterproof for submersion. Do not immerse the headphones in water, swim, or shower with them.
Storage
When not in use, store the headphones in their charging case to protect them and keep them charged. Store in a cool, dry place away from extreme temperatures and direct sunlight.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Earbuds not pairing with device | Bluetooth off; earbuds not in pairing mode; interference; previously paired device. | Ensure Bluetooth is on. Place earbuds in case, close, then reopen to re-enter pairing mode. Turn off Bluetooth on other devices. Forget/delete previous pairing and re-pair. |
| Only one earbud working | Low battery; earbuds not properly connected to each other; individual earbud pairing issue. | Charge both earbuds fully. Place both earbuds back in the case, close the lid, wait 5 seconds, then open. This often resets the connection. Re-pair if necessary. |
| No sound or low volume | Device volume too low; earbud volume too low; improper fit; dirty ear tips. | Increase volume on both device and earbuds. Adjust earbud position for a secure fit. Clean ear tips and earbud mesh. |
| Charging case not charging | Faulty cable/adapter; dirty charging port. | Try a different USB cable and power adapter. Ensure the charging port is clean and free of debris. |
| Touch controls not responding | Improper touch; temporary software glitch. | Ensure you are touching the correct area (MFB). Try restarting the earbuds by placing them in the case and taking them out again. |
