8. Troubleshooting
| Problem | Possible Solution |
|---|---|
| Ear muffs feel too tight. | The tight seal is essential for effective noise reduction. While they may feel tight initially, they are designed for comfort during long sessions. Ensure the headband is adjusted correctly. |
| Not completely soundproof. | These ear muffs are designed to reduce deafening, sustained noise to a safe level while allowing you to hear important environmental sounds, not to be completely soundproof. |
| Cannot make/receive calls. | Voice calls only work when the ear muffs are connected via Bluetooth mode. Ensure your device is properly paired via Bluetooth. |
| Volume control knob not working. | The volume control knob functions only when the ear muffs are in aux-in (line-in) mode, connected via the 3.5mm audio cable. |
| Cannot pair via Bluetooth. | Ensure the ear muffs are in pairing mode (red and blue lights flashing alternately). Check your device's Bluetooth settings and try reconnecting. Make sure the ear muffs are charged. |
| No audio in Bluetooth mode. | Ensure the ear muffs are successfully paired and connected to your device. Check the volume levels on both the ear muffs and your audio source. |
