Sound Amplification and Suppression
The muffs utilize two Hi-Gain Omnidirectional Microphones to pick up and amplify low-level sounds, enhancing your awareness of your surroundings. When loud noises occur, the Sound Activated Compression (SAC) technology instantly reacts, compressing harmful sounds to a safe level within 0.02 seconds, protecting your hearing.

Battery Replacement
When the sound quality diminishes or the unit fails to power on, it is time to replace the AAA batteries. Follow the battery installation steps outlined in the Setup section.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Muffs do not power on. | Dead or incorrectly installed batteries. | Check battery polarity. Replace with fresh AAA batteries. |
| No sound or very low ambient sound amplification. | Volume knob set too low; dead batteries; improper fit. | Rotate volume knob clockwise to increase. Replace batteries. Adjust muffs for a secure fit over ears. |
| Bluetooth audio is low or inaudible, especially in noisy environments. | Mobile device volume too low; environmental noise overpowering Bluetooth audio. | Increase volume on your connected mobile device. Note that in very loud environments, ambient sound amplification takes precedence for hearing protection, which may make Bluetooth audio less prominent. |
| Cannot pair with Bluetooth device. | Muffs not in pairing mode; device Bluetooth off; too far from device. | Ensure muffs are on. Turn Bluetooth off and on again on your device. Move closer to the muffs. Try restarting both devices. |
| Muffs feel loose or uncomfortable. | Improper headband adjustment. | Adjust the ear cups up or down along the metal wire frame until a snug and comfortable fit is achieved. |
