2. Product Features
The KZ Gold Silver and Copper Mixed Upgrade Cable is engineered with advanced materials and design to deliver superior audio performance. Key features include:
- HiFi Transparent Sound Quality: The cable base, made of high-purity oxygen-free copper, offers a wide frequency range and precise mid-bass rhythm. The addition of gold enhances tone smoothness and flexibility, while silver provides silky high frequencies and improved sound transparency.

3. Key Components
The cable features a robust 3.5mm metal plug for universal compatibility and a cubic weaving technique for enhanced performance.
- 3.5mm Metal Plug: This standard male-to-male auxiliary connector ensures a stable and high-speed signal transfer, compatible with various headphone devices and audio sources.
- Cubic Weaving Technique: The soft cable body, constructed with this technique, effectively reduces the stethoscope effect, minimizing microphonics and improving listening comfort.

4. Setup and Installation
Follow these steps to connect your KZ Upgrade Cable to your In-Ear Monitors and audio source:
- Identify Connectors: The cable has two 0.75mm 2-pin connectors for your IEMs and one 3.5mm metal plug for your audio device.
- Connect to IEMs: Carefully align the 2-pin connectors with the corresponding sockets on your IEMs. Ensure the correct orientation (left and right channels) and gently push until they are securely seated. Do not force the connection.
- Connect to Audio Source: Insert the 3.5mm metal plug into the headphone jack of your audio device (e.g., smartphone, digital audio player, amplifier).
- Verify Connection: Ensure all connections are firm to prevent signal interruption.

5. Operating Instructions
Once the cable is securely connected to your IEMs and audio source, simply play your desired audio content. The cable functions as a passive audio conductor, transmitting the electrical signals from your source to your IEMs. No additional controls or operations are required on the cable itself.
6. Maintenance and Care
To ensure the longevity and optimal performance of your KZ Upgrade Cable, follow these maintenance guidelines:
- Storage: Store the cable loosely coiled to prevent kinks and tangles. Avoid sharp bends or excessive force when coiling.
- Cleaning: Wipe the cable periodically with a soft, dry cloth to remove dust and oils. Avoid using harsh chemicals or abrasive materials.
- Handling: Always grasp the plug when connecting or disconnecting the cable, rather than pulling on the wire itself, to prevent damage to the connectors.
- Environmental Conditions: Avoid exposing the cable to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
7. Troubleshooting
If you encounter issues with your KZ Upgrade Cable, consider the following:
- No Sound: Ensure both the 2-pin connectors to your IEMs and the 3.5mm plug to your audio source are fully inserted and secure. Check the volume level on your audio device.
- Intermittent Sound/Static: Re-seat all connections. Inspect the connectors for any visible damage or debris. Try the cable with a different audio source or IEMs to isolate the problem.
- Poor Sound Quality: Ensure your audio source is playing high-quality audio files. Verify that the cable is not damaged.
If problems persist after following these steps, please refer to the warranty and support information.
