3. Setup Instructions
3.1 Connecting the Headphones
- Locate the detachable audio cable.

Important Note for PC Users:
If your computer has separate output slots for microphone and sound (typically two distinct 3.5mm jacks), a computer convert cable (Y-splitter) is required for full functionality of both audio and microphone. This cable is not included in the standard package.

3.2 Adjusting for Comfort
The headphones feature a scalable design to fit various head types and soft, memory foam ear pads for comfortable wear. Adjust the headband to ensure the earcups sit comfortably and securely over your ears. The earcups are designed to provide a soft, round surround fit.

3.3 Foldable Design
The headphones feature an invisible foldable design for easy portability and storage. To fold, gently collapse the earcups inwards towards the headband. Reverse the process to unfold.

5. Maintenance
5.1 Cleaning
- Use a soft, dry cloth to wipe the earcups and headband.
- For ear pads, a slightly damp cloth can be used, but ensure they are completely dry before use.
- Avoid using harsh chemicals or abrasive materials, as these can damage the headphone finish and materials.

The audio cable is made with a hand-woven nylon braided wire and a gold-plated copper core for durability and clear sound transmission. To prolong its life:
- Avoid sharp bends or kinks in the cable.
- Do not pull the cable forcefully when disconnecting; always grasp the plug.
- Store the cable neatly when not in use to prevent tangling.

6. Troubleshooting
6.1 No Sound or Low Volume
- Check Cable Connection: Ensure the 3.5mm audio cable is securely plugged into both the headphones and your device.
- Device Volume: Verify that the volume on your connected device is turned up and not muted.
- In-line Volume Control: Adjust the volume slide bar on the in-line remote control.
- Source Device: Test the headphones with another audio source to rule out an issue with the original device.
6.2 Microphone Not Working

- Device Settings: Check your device's audio input settings to ensure the external microphone is selected and not muted.
- Application Settings: Verify that the microphone is enabled and unmuted within the application you are using (e.g., gaming client, video call software).
6.3 Distorted Sound Quality
- Volume Level: Reduce the volume on your device and headphones if the sound is distorted at high levels.
- Cable Condition: Inspect the audio cable for any visible damage or kinks. Try using a different compatible cable if available.
