Multiple Modes Available
The KZ Xtra offers three distinct modes to adapt to your listening environment:
- ANC Mode (Active Noise Cancellation): Adopts advanced noise cancellation algorithms to accurately capture environmental noise and emit reverse sound waves, effectively counteracting external noise for an immersive listening experience.
- High Performance Mode (Gaming Mode): Provides ultra-low latency (as low as 55ms) and stable transmission, allowing you to clearly perceive in-game audio cues like footsteps and gunshots.
- Transparency Mode: Allows you to clearly perceive and listen to external sounds without having to remove your earbuds, enhancing situational awareness.
Overview of ANC, High Performance, and Transparency Modes
Maintenance
- Cleaning: Regularly clean the earbuds, especially the eartips and charging contacts, with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials.
- Storage: When not in use, store the earbuds in their charging case to protect them from dust, damage, and to keep them charged.
- Avoid Water: These earbuds are not waterproof. Avoid exposure to water, rain, or excessive moisture.
- Temperature: Do not expose the earbuds or charging case to extreme temperatures (hot or cold).
Troubleshooting
- Earbuds not pairing:
- Ensure both earbuds are charged. Place them back in the case, close the lid, then open it again to re-enter pairing mode. Check your device's Bluetooth settings and try reconnecting. If issues persist, try forgetting the device on your phone and re-pairing.
- No sound or low volume:
- Check the volume levels on both your device and the earbuds. Ensure the earbuds are properly seated in your ears. Try cleaning any debris from the earbud nozzles.
- Charging issues:
- Ensure the charging cable is securely connected to both the case and the power source. Check the charging contacts on the earbuds and inside the case for any obstructions or dirt. Use a certified Type-C cable.
- ANC not working effectively:
- Ensure the earbuds are properly sealed in your ear canal with the correct size eartips. Activate ANC mode using the touch controls. Environmental noise reduction is most effective for low-frequency sounds.
User Tips
- Bluetooth Compatibility: The KZ Xtra uses Bluetooth 5.4, which is backward compatible with older Bluetooth versions like 5.2. You should have no issues connecting to devices with Bluetooth 5.2 or earlier.
- Multipoint Connection: The KZ Xtra does not explicitly support multipoint connection (connecting to two devices simultaneously). You will need to disconnect from one device before connecting to another.
- Optimal Fit: Experiment with the different eartip sizes provided to find the best fit for your ears. A good seal is crucial for effective noise cancellation and optimal sound quality.
- Gaming Performance: For the best gaming experience, ensure you activate the High Performance Mode (Gaming Mode) via the touch controls to benefit from the ultra-low latency.
