Using the Baseus App
For a personalized listening experience, download the official Baseus app. The app allows you to:
- Customize touch controls.
- Adjust EQ modes and Bass Boost.
- Enable Spatial Acoustics (Note: On Android devices, LDAC and Spatial Acoustics cannot be used simultaneously due to system limitations).
- Locate your earbuds (requires OPS access).
Maintenance
Cleaning
- Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth.
- Do not use abrasive cleaners, solvents, or aerosol sprays.
- Ensure charging contacts on both earbuds and case are free from dust and debris.
Storage
When not in use, store the earbuds in their charging case to protect them and ensure they remain charged.
Water Resistance (IP55)
The earbuds are IP55 water-resistant, meaning they are protected against dust and low-pressure water jets from any direction. This makes them suitable for workouts and light rain. However, they are not designed for submersion in water or exposure to high-pressure water. The charging case is not water-resistant.
Troubleshooting
- Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to re-enter pairing mode. Check your device's Bluetooth settings to ensure it's discoverable and try re-pairing.
- No sound or low volume: Check the volume levels on both your device and the earbuds. Ensure the 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 if necessary.
- ANC not working effectively: Ensure the earbuds are properly fitted in your ears. Switch between ANC modes using the touch controls or the Baseus app.
- Intermittent connection: Ensure your device is within the Bluetooth range (up to 10 meters) and there are no significant obstructions.
