4.2 Battery Life and LED Display
The earbuds provide 8-9 hours of listening time on a single charge (at 70% volume). The 300mAh charging case offers an additional 4 full charges, extending the total playback time to approximately 30 hours.
The LED display on the charging case shows the remaining battery percentage of the case and individual battery indicators for the left and right earbuds.
5. Maintenance
5.1 Waterproofing (IPX5)
The LENCENT S52 earbuds are IPX5 waterproof, meaning they are protected against low-pressure water jets from any direction. This makes them suitable for workouts, jogging, and use in light rain.
Important: Do not wear the earbuds while swimming or bathing, as IPX5 rating does not protect against submersion.
5.2 Cleaning and Storage
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Remove ear tips and clean them with mild soap and water if necessary, ensuring they are completely dry before reattaching.
- Avoid using abrasive cleaners or solvents.
- Store the earbuds in their charging case when not in use to protect them and keep them charged.
- Keep the device away from extreme temperatures and humidity.
6. Troubleshooting
- Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid. Check your device's Bluetooth settings to ensure it's discoverable and try re-pairing.
- 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.
- No sound or low volume: Check the volume level on both your device and using the earbud touch controls. Ensure earbuds are properly seated in your ears.
- Charging issues: Verify the charging cable is securely connected to both the case and the power source. Clean the charging contacts on the earbuds and inside the case with a dry cotton swab.
- Touch controls unresponsive: Ensure your fingers are clean and dry. Try resetting the earbuds by placing them in the case and closing the lid for a few seconds.
