Connectivity Options
- Wired Connection: Connect the 3.5mm jack to your audio source (smartphone, tablet, computer, music production equipment).
- Bluetooth (Optional): If you have a compatible Bluetooth module (not included with this specific model, but supported by the detachable cable system), you can convert your KZ ASX into wireless earphones. Refer to the Bluetooth module's manual for pairing instructions.
Maintenance and Care
- Cleaning: Regularly wipe the earpieces and cable with a soft, dry cloth. For the resin body, a slightly damp cloth can be used, followed by drying. Avoid harsh chemicals or abrasive materials.
- Ear Tips: Remove and clean ear tips periodically with mild soap and water. Ensure they are completely dry before reattaching.
- Cable Care: The detachable cable is designed for durability. Avoid sharp bends or excessive pulling. When detaching, pull directly from the connector, not the cable itself.
- Storage: Store your earphones in a clean, dry place, preferably in a protective case, to prevent dust accumulation and physical damage.
- Water Resistance: The product description mentions "Waterproof" for Water Resistance Level. While this indicates a degree of protection, it is generally recommended to avoid prolonged exposure to water or submersion to ensure longevity.
Troubleshooting
- No Sound:
- Ensure the 3.5mm jack is fully inserted into your audio device.
- Check that the detachable 2-pin cable is securely connected to both earpieces.
- Verify the audio source volume is turned up and not muted.
- Test with a different audio source or cable if possible.
- Poor Sound Quality / Distortion:
- Ensure ear tips provide a good seal in your ear canal. A poor seal can affect bass response and overall sound.
- Check for debris in the earphone nozzles or on the ear tips.
- Reduce the volume on your audio source if distortion occurs at high levels.
- Uncomfortable Fit:
- Experiment with different sizes of ear tips to find the best fit for your ears.
- Adjust the earhook to ensure it sits comfortably and securely over your ear.
- Microphone Not Working:
- Ensure the 3.5mm jack is fully inserted into a device that supports microphone input.
- Check your device's audio settings to ensure the correct microphone input is selected.
