5. Maintenance and Care
To ensure the longevity and optimal performance of your Baseus Bass BS2 Lite earbuds, follow these care guidelines:
- Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials.
- Water Resistance: The earbuds are IP55 water and dust resistant, meaning they can withstand sweat and light splashes. Do not submerge them in water or expose them to heavy rain. Ensure they are dry before placing them back in the charging case.
- Storage: When not in use, store the earbuds in their charging case to protect them from dust and damage. Store in a cool, dry place away from extreme temperatures.
- Charging: Use only the provided USB-C cable or a certified equivalent for charging.
6. Troubleshooting
If you encounter issues with your earbuds, try the following solutions:
6.1 Pairing Issues
- Earbuds not pairing with device: Ensure Bluetooth is enabled on your device and the earbuds are in pairing mode (open the charging case). Try turning Bluetooth off and on again on your device.
- 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 re-syncs them.
- Earbuds not appearing in Bluetooth list: Ensure the earbuds are charged. Try resetting the earbuds (refer to the full user manual if a specific reset procedure is available, otherwise, a factory reset usually involves holding a button on the case for several seconds).
6.2 Sound Issues
- 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.
- Poor call quality: Ensure the earbuds' microphones are not obstructed. The 2-Mic AI ENC technology helps, but clear placement is important.
6.3 Charging Issues
- Earbuds not charging: Ensure the charging contacts on both the earbuds and the case are clean and dry. Check the USB-C cable and power adapter for damage.
- Charging case not charging: Verify the USB-C cable and power source are working correctly.
