ENC Noise Cancelling

The C16-New earbuds are equipped with True ENC (Environmental Noise Cancelling) technology. This feature reduces external noise and minimizes sound leakage, ensuring crystal clear calls and an immersive listening experience. While it effectively reduces background noise, it allows you to maintain some awareness of your surroundings for safety, especially during outdoor activities.

Maintenance

IP7 Waterproof Protection

The earbuds boast an IP7-rated protection, making them resistant to ordinary splashing water and rain. This makes them suitable for sports, workouts, and use in various weather conditions. However, they are not designed for submersion in water.

Cleaning and Storage

To maintain optimal performance and hygiene, regularly clean your earbuds and charging case. Use a soft, dry cloth to wipe down the surfaces. For the ear tips, you can gently remove them and clean with mild soap and water, ensuring they are completely dry before reattaching. Store the earbuds in their charging case when not in use to protect them and keep them charged.

Troubleshooting

If you encounter any issues with your Kuizil C16-New earbuds, please refer to the following common troubleshooting tips:

• Earbuds not pairing: Ensure Bluetooth is enabled on your device. Take both earbuds out of the charging case to activate pairing mode. If they don't appear, try turning Bluetooth off and on again on your device, or reset the earbuds (refer to the detailed user manual for specific reset instructions).
• Only one earbud working: Place both earbuds back into the charging case, close the lid, and then open it again. Ensure both earbuds are properly seated and charging. If the issue persists, try re-pairing them with your device.
• Sound quality issues: Ensure the ear tips are the correct size for a snug fit. Clean any debris from the earbud speakers. Check your device's volume settings.
• Charging issues: Ensure the USB-C cable is securely connected to both the case and the power source. Check if the charging contacts on the earbuds and inside the case are clean and free of obstructions.
• Short battery life: Ensure earbuds and case are fully charged before use. Battery life can vary based on volume level and usage.
