2. Key Features
- High-Fidelity Sound: Constructed with high-purity copper and multi-shielding to ensure optimal signal transfer and minimize interference, delivering clear and pristine audio.
- Durable Nylon Braid: The cable is encased in a robust nylon braid, offering protection against scratches, abrasion, and tangling, thereby extending its lifespan.
- 24K Gold-Plated Connectors: Features 24K 15U gold-plated plugs that resist oxidation and corrosion, enhancing durability and maintaining superior sound quality over time.
- Solid Construction: Designed with secure connections on both the 3.5mm (1/8") male end and the 6.35mm (1/4") male connector ends for reliable performance.

3. Setup Instructions
Follow these steps to connect your UGREEN 1/8 to 1/4 Stereo Cable:
- Identify Ports: Locate the 3.5mm (1/8 inch) audio output jack on your source device (e.g., smartphone, laptop, PC). Identify the dual 6.35mm (1/4 inch) mono input jacks (typically labeled L/R for Left/Right stereo channels) on your receiving audio equipment (e.g., mixer, amplifier, speaker).
- Connect Source: Insert the single 3.5mm TRS (Tip-Ring-Sleeve) connector of the UGREEN cable into the 3.5mm audio output jack of your source device.
- Connect Receiving Equipment: Insert the two 6.35mm TS (Tip-Sleeve) mono connectors into the corresponding Left (L) and Right (R) 6.35mm input jacks on your audio equipment. Ensure the red-banded connector is typically for the Right channel and the white/silver-banded connector for the Left channel, if applicable.
- Secure Connections: Gently push the connectors firmly into their respective ports to ensure a secure and stable connection.

4. Operating Instructions
Once the cable is securely connected, operate your audio system as follows:
- Power On: Turn on your source device and receiving audio equipment.
- Select Input: On your receiving audio equipment (mixer, amplifier), select the input channel(s) corresponding to where the UGREEN cable is connected.
- Adjust Volume: Start with the volume levels low on both your source device and receiving equipment. Gradually increase the volume to a comfortable listening level.
- Stereo vs. Mono: This cable is designed for stereo output from the 3.5mm source to dual mono inputs on the receiving device, providing a stereo image. If your receiving device only has a single 6.35mm input, you may only use one of the 1/4 inch plugs for a mono signal.

6. Maintenance
To ensure the longevity and optimal performance of your UGREEN cable, follow these maintenance guidelines:
- Storage: Store the cable in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling or bending the cable at sharp angles to prevent internal damage.
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Do not use harsh chemicals or abrasive cleaners, as these can damage the cable's braiding or the gold plating on the connectors.
- Handling: Always grasp the connector housing when plugging or unplugging the cable, rather than pulling on the cable itself. This prevents strain on the connection points.
- Inspection: Periodically inspect the cable for any signs of wear, fraying, or damage to the connectors. If significant damage is observed, discontinue use to prevent potential audio issues or damage to connected equipment.
7. Troubleshooting
If you encounter issues with your UGREEN 1/8 to 1/4 Stereo Cable, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output | Loose connections, incorrect input selection, low volume, faulty cable. | Ensure all connectors are firmly seated. Verify the correct input is selected on your audio equipment. Increase volume on both source and receiving devices. Test with another cable if available. |
| Static or humming noise | Interference, ground loop, damaged cable, poor connection. | Ensure the cable is not running parallel to power cables. Try connecting devices to the same power outlet. Check for secure connections. Replace the cable if damaged. |
| Audio only from one speaker/channel | One of the 6.35mm connectors is loose or faulty, mono signal source, balance settings. | Check both 6.35mm connections. Ensure your source device is outputting a stereo signal. Verify balance settings on your audio equipment. |
