8.1 Cleaning

Regularly clean your earbuds and charging case to maintain optimal performance and hygiene.

• Use a soft, dry, lint-free cloth to wipe the earbuds and charging case.
• For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
• Ensure charging contacts are clean and dry before placing earbuds in the case.

9. Troubleshooting

If you encounter issues with your QCY Crossky C30S earbuds, refer to the following common solutions:

• Earbuds not pairing: Ensure earbuds are charged. Place them back in the case, close, then open again to re-enter pairing mode. Check your device's Bluetooth settings and try reconnecting.
• Only one earbud working: Place both earbuds back in the charging case, close the lid, then open it again. This often re-syncs them. If the issue persists, try resetting the earbuds (refer to the QCY app or manufacturer's website for specific reset instructions).
• Poor sound quality: Ensure the earbuds are worn correctly and securely. Check for any obstructions on the speaker grilles. Ensure your device is within the Bluetooth range (10 meters) and there are no significant interferences.
• Earbuds not charging: Verify the charging cable is securely connected to both the case and the power source. Ensure the charging contacts on both the earbuds and the case are clean and free of debris.
• Touch controls unresponsive: Ensure your fingers are clean and dry. Try restarting the earbuds by placing them in the case and taking them out. If customization was done via the app, check app settings.
