3. Setup
- Connecting the Cable:

- Wearing the Earphones:
Place the earphone units into your ears, ensuring a snug and comfortable fit. The pre-formed ear hooks should rest over the top of your ears to provide stability. Adjust the cable behind your ears for optimal comfort and to minimize microphonics.
- Connecting to an Audio Source:
Plug the 3.5mm jack of the cable into your audio device (e.g., smartphone, music player, computer). Ensure the connection is secure.
- Optional Bluetooth Module Upgrade:
For wireless functionality, you can replace the standard cable with a compatible Bluetooth module (sold separately). Follow the instructions provided with the Bluetooth module for pairing and operation.

5. Maintenance
- Cleaning Earphone Units:
Gently wipe the earphone units with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Ensure no moisture enters the driver or connector areas.

Remove the silicone ear tips and wash them with mild soap and water. Rinse thoroughly and allow them to dry completely before reattaching. Replace ear tips if they become worn or damaged.
- Cable Care:
Avoid sharp bends or excessive pulling on the cable. Store the cable neatly to prevent tangling. If the cable becomes damaged, it can be replaced due to its detachable design.
- Storage:
When not in use, store your KZ EDX earphones in a clean, dry place, preferably in a protective case, to prevent dust accumulation and physical damage.
