3.1 Hearing Protection (85dB Volume Limiter)
The A63 headphones feature a built-in fixed safe sound volume limitation set to 85dB. This level is recommended by the World Health Organization (WHO) to prevent hearing damage, allowing children to listen safely without constant parental supervision. This ensures that audio will not exceed a safe listening level, protecting young ears.

4. Setup
- Unpack: Carefully remove the headphones from their packaging.
- Connect: Insert the 3.5mm audio jack firmly into the headphone port of your desired device (e.g., smartphone, tablet, computer).
- Adjust Headband: Gently slide the earcups up or down along the headband to achieve a comfortable and secure fit on the user's head. Ensure both earcups fully cover the ears for optimal sound and comfort.
5. Operating Instructions
- Power On/Off Device: Ensure your audio device is powered on and playing content.
- Volume Control: Adjust the volume directly on your connected device. The headphones have a built-in 85dB volume limiter, so even if the device volume is set to maximum, the output will remain at a safe level for children.
- Usage: Enjoy listening to music, audiobooks, watching videos, or participating in online classes.
6. Maintenance
- Cleaning: Use a soft, dry cloth to wipe the headphones clean. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the earcup or jack areas. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the headphones in a clean, dry place away from extreme temperatures and direct sunlight. Avoid tangling the cable by coiling it neatly.
- Handling: Always pull from the plug, not the cable, when disconnecting from a device. Avoid excessive bending or twisting of the cable to prevent internal damage.
7. Troubleshooting
- No Sound:
- Ensure the 3.5mm jack is fully inserted into the device's audio port.
- Check the volume level on your connected device.
- Test the headphones with another device to rule out a device-specific issue.
- Sound is Too Low/High:
- Adjust the volume on your connected device. Remember, the headphones have an 85dB volume limiter for safety, so the maximum volume will be capped.
- Audio is Distorted:
- Ensure the 3.5mm jack is clean and free of debris.
- Try a different audio source or device.
