4. Maintenance
Cleaning
- Wipe the headphones with a soft, dry cloth.
- Do not use harsh chemicals or abrasive cleaners.
- Clean the earpads gently with a damp cloth if necessary, and allow them to air dry completely before use.
Storage
When not in use, store your headphones in the provided portable carrying bag to protect them from dust and scratches. Avoid storing them in extreme temperatures or high humidity.
Earpad Care
The memory foam earpads are designed for comfort and durability. To maintain their quality, avoid prolonged exposure to direct sunlight and sharp objects. Replacement earpads may be available from the manufacturer.
5. Troubleshooting
- No Sound:
- Ensure the audio cable is securely plugged into both the headphones and the audio source.
- Check the volume level on your audio source and on the headphones (if applicable).
- Test with a different audio source or cable to rule out a faulty component.
- Poor Sound Quality (Distortion, Low Volume):
- Verify that the audio cable is fully inserted and not damaged.
- Ensure the audio source's volume is not too high, causing distortion.
- Check for debris in the audio jacks.
- If one side is lower than the other, try swapping the cable or testing with another device to isolate the issue.
- Microphone Not Working:
- Ensure you are using the 3.5mm cable with the integrated microphone.
- Check microphone settings on your connected device (e.g., computer, smartphone).
- For PC use, a 3.5mm speaker/mic splitter may be required if your PC has separate audio input/output jacks.
- Headphones Uncomfortable / Ears Sweat:
- Adjust the headband and earcup rotation for a better fit.
- The memory foam earpads are designed to be breathable, but prolonged use in warm environments may still cause some discomfort. Take short breaks if needed.
Warning: Do not use this product in a wet environment.
