Setup
1. Attaching the Cable:
- Identify the left (L) and right (R) earbuds and the corresponding connectors on the cable. The cable connectors are typically marked with 'L' and 'R'.
- Align the 2-pin connector on the cable with the receptacle on the earbud. Ensure the pins are correctly oriented.
- Gently push the connector into the earbud until it is securely seated. Do not force the connection.
- Repeat for the other earbud.

2. Selecting and Installing Ear Tips:
Proper ear tip selection is crucial for sound quality and comfort. Experiment with the included ear tips to find the best fit for your ears. A good seal provides optimal bass response and noise isolation.
- Gently remove the pre-installed ear tips by twisting and pulling.
- Select a new pair of ear tips.
- Push the new ear tip onto the nozzle of the earbud until it is securely attached.
3. Wearing the Earbuds:
- Insert the earbud into your ear canal.
- Loop the cable over the top of your ear. This over-ear design helps secure the earbuds and reduces microphonics (cable noise).
- Adjust the earbud and cable for a comfortable and secure fit.

Operating Instructions
1. Connecting to an Audio Source:

2. Using the In-line Microphone and Control (if applicable):
If your KZ AS16 Pro variant includes an in-line microphone and control button, you can perform the following functions:
- Single Press: Play/Pause music, Answer/End call.
- Double Press: Skip to next track.
- Triple Press: Go to previous track.
- Long Press: Activate voice assistant (if supported by your device).
Note: Functionality may vary slightly depending on your connected audio device and operating system.
Maintenance
1. Cleaning the Earbuds and Ear Tips:
- Regularly clean the ear tips with a soft, damp cloth. For silicone tips, you can remove them and wash them with mild soap and water, ensuring they are completely dry before reattaching.
- Use a dry, soft cloth to wipe the earbud shells. Avoid using harsh chemicals or abrasive materials.
- Gently remove any earwax buildup from the earbud nozzles using a small, soft brush or a specialized cleaning tool. Ensure no debris enters the nozzle.
2. Cable Care:
- Avoid sharp bends or excessive pulling on the cable.
- When storing, coil the cable loosely to prevent tangling and damage.
- Always grasp the plug, not the cable, when disconnecting from an audio source.
3. Storage:
When not in use, store your earbuds in a clean, dry place, preferably in a protective case, to prevent dust accumulation and physical damage.
