Maintenance

• Cleaning: Use a soft, dry cloth to clean the ear pads and other surfaces of the headphones. Do not use harsh chemicals or abrasive materials.
• Storage: When not in use, store the headphones in the provided portable PU bag to protect them from dust and damage.
• Environment: Do not use this product in wet environments.
• Cable Care: Handle cables gently. Avoid excessive pulling or bending, especially near the connectors, to prevent internal wire damage.

Troubleshooting

No Sound or Intermittent Audio:

• Ensure all cables are securely connected to both the headphones and the audio source. Verify the jack lock system is engaged.
• Check the volume levels on both your audio source and the in-line controls (if using the mic cable).
• Test with a different audio source or cable to rule out a faulty component.

Microphone Not Working:

• Ensure you are using the 1.2m 3.5mm Audio Cable with In-Line Microphone.
• Check if the microphone mute switch on the in-line control is in the 'on' position.
• Verify microphone input settings on your connected device (PC, laptop, etc.).

Discomfort During Use:

• Adjust the headband to fit your head size comfortably.
• Ensure the earcups are properly positioned over your ears. The memory foam ear pads are designed for comfort.

Sound Leakage / Poor Noise Isolation:

• Ensure the earcups are fully sealed around your ears. Adjust the fit of the headphones.
• Note that these headphones feature passive noise cancellation, not active noise cancellation (ANC).
