6. Maintenance
- Cleaning: Regularly clean the ear tips and the mesh of the earbuds with a soft, dry, lint-free cloth. You can gently remove the silicone ear tips for a more thorough cleaning with mild soap and water, ensuring they are completely dry before reattaching.
- Storage: Always store the earbuds in their charging case when not in use to protect them from dust, damage, and to keep them charged.
- Avoid Moisture: The earbuds are not waterproof. Avoid exposure to water, sweat, or high humidity.
- Charging Port: Keep the Type-C charging port free of dust and debris.
7. Troubleshooting
- No Sound / Pairing Issues:
- Ensure both earbuds are charged. Turn off and on your device's Bluetooth, then try re-pairing. If issues persist, reset the earbuds (refer to the app or manufacturer's support for specific reset instructions).
- Unbalanced Sound / Poor Noise Cancellation:
- Ensure the ear tips are correctly sized and provide a good seal in your ear canal. Try different sized ear tips. Check for any debris blocking the earbud mesh. Note that ANC performance can vary based on ear shape, tip size, and environment.
- Battery Drains Quickly (e.g., one earbud faster than the other):
- This can sometimes occur due to differences in usage (e.g., one earbud used more for calls or as the primary connection). Ensure both earbuds are placed correctly in the charging case and making proper contact for charging. If the issue persists, monitor usage patterns and consider a full charge cycle for both earbuds and the case.
- Touch Controls Not Responding:
- Ensure your fingers are clean and dry. Sometimes a quick re-pairing or placing the earbuds back in the case and taking them out can resolve minor glitches.
8. User Tips
- Utilize the KZ App: For the best experience, download the official KZ app. It allows for fine-tuning EQ settings and managing sound modes, which can significantly enhance your listening experience.
- Find Your Perfect Fit: Experiment with the included ear tip sizes (S, M, L) to find the most comfortable and secure fit. A good seal is essential for maximizing both sound quality and the effectiveness of the active noise cancellation.
- Gaming Mode for Low Latency: Remember to activate the High-Performance / Gaming Mode (triple tap) when playing games or watching videos to benefit from the ultra-low 55ms latency for perfectly synchronized audio and visuals.
