5. Maintenance
5.1. Cleaning
Regularly clean your earbuds and charging case to maintain optimal performance and hygiene. Use a soft, dry, lint-free cloth to wipe down the surfaces. For the eartips, remove them and clean with a mild soap solution if necessary, ensuring they are completely dry before reattaching.
5.2. Water Resistance

However, they are not designed for submersion in water. Avoid exposing them to strong jets of water or prolonged immersion.
6. Troubleshooting
If you encounter any issues with your truke BTG Crystal earbuds, please refer to the following common troubleshooting steps:
- No Sound: Ensure earbuds are charged, connected to your device, and volume is up. Try re-pairing.
- Connection Issues: Make sure Bluetooth is enabled on your device and the earbuds are within range (up to 10 meters). Try forgetting the device in your Bluetooth settings and re-pairing.
- One Earbud Not Working: Place both earbuds back in the case, close it, wait a few seconds, then open it again. This often re-syncs them.
- Charging Problems: Check the charging cable and power source. Ensure the charging contacts on the earbuds and case are clean and free of debris.
- Poor Call Quality: Ensure the microphones are not obstructed. If in a noisy environment, the ENC feature should help, but extreme noise may still affect clarity.
