6. Maintenance

• Cleaning: Regularly wipe the earphones and cable with a soft, dry cloth. For eartips, remove them and clean with mild soap and water, then rinse thoroughly and allow to dry completely before reattaching.
• Storage: When not in use, store the earphones in their original packaging or a protective case to prevent damage from dust, moisture, and tangling.
• Cable Care: Avoid sharp bends or excessive pulling on the cable. The detachable design allows for easy replacement if the cable becomes damaged.
• Avoid Moisture: The KZ Duonic earphones are not waterproof. Avoid exposure to water, sweat, or high humidity.

7. Troubleshooting

7.1 No Sound or Distorted Sound

• Check Connections: Ensure the cable is securely attached to both the earphones and your audio source.
• Audio Source: Verify that your audio source (phone, player, computer) is playing sound and its volume is turned up.
• Cable Integrity: Try using a different cable if available, or test the earphones with another audio source to rule out a faulty cable.
• Eartip Seal: Ensure the eartips create a good seal in your ear canal. A poor seal can lead to a lack of bass and overall thin sound.
• Tuning Switches (if applicable): If you have the tuning version, ensure the switches are set to a desired profile. Try resetting them to the 'all off' position.

7.2 Microphone Not Working

• Check Connection: Ensure the microphone cable is fully inserted into the earphone and the audio source.
• Device Settings: Verify that the correct microphone input is selected in your device's audio settings.
• Compatibility: Some devices may have specific requirements for external microphones.
• Cable Type: Ensure you are using a cable with a built-in microphone if you intend to use this feature.

9. User Tips

• Choosing Your Version: If you prefer a balanced sound without needing to adjust settings, the 'No Switches' version is ideal. For those who enjoy customizing their audio, the 'Bass Improved Version with Switches' offers greater flexibility.
• Eartip Fit: A common factor affecting sound quality, especially bass, is the eartip seal. Experiment with all included eartip sizes to find the one that provides the best isolation and comfort for your ears.
• Cable Management: To prevent tangling and extend cable life, consider using a cable tie or winding the cable neatly when storing your earphones.
