4. Setup
4.1 Battery Installation
- Locate the battery compartment on one of the earcup shells.
- Gently open the battery compartment cover.
- Insert 2 AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
4.2 Adjusting the Headband
For optimal comfort and noise reduction, adjust the headband to fit your head snugly.
- Extend or retract the headband slides on each side until the earcups cover your ears completely and comfortably.
- Ensure the earmuffs create a tight seal around your ears without excessive pressure.
5. Operating Instructions
5.1 Power On/Off and Volume Control
- Locate the power/volume knob on the earcup.
- Rotate the knob clockwise to power on the earmuffs. An LED indicator may light up.
- Continue rotating the knob clockwise to increase the amplification volume of ambient sounds. Rotate counter-clockwise to decrease volume.
- To power off, rotate the knob counter-clockwise until it clicks off and the LED indicator turns off.

5.2 Sound Amplification and Noise Reduction
The earmuffs feature intelligent sound processing:
- Amplification: Built-in microphones capture and amplify low-level ambient sounds (e.g., speech, animal movements) up to 5 times, as long as they are below 82 dB. This enhances communication and awareness in quiet moments.
- Noise Reduction: When sudden loud noises (e.g., gunshots) exceed 82 dB, the amplification system instantly shuts off, and the earmuffs provide passive noise reduction (NRR 23dB / SNR 28dB) to protect your hearing. This reaction time is approximately 0.0005 seconds.

5.3 Bluetooth Pairing (If Applicable)
If your model includes Bluetooth functionality:
- Ensure the earmuffs are powered on.
- Activate Bluetooth on your mobile device.
- Search for available devices and select "PROHEAR Earmuffs" (or similar name) from the list.
- Once paired, you can stream audio or make calls through the earmuffs.
5.4 Using the 3.5mm Audio Input
To connect an external audio device:
- Plug one end of the provided 3.5mm audio cable into the AUX input jack on the earcup.
- Plug the other end into the audio output of your external device (e.g., radio, MP3 player).
- Adjust the volume on your external device and the earmuffs as needed.

6. Maintenance
6.1 Cleaning Ear Cushions
Regular cleaning helps maintain hygiene and comfort.
- Wipe the ear cushions with a damp cloth and mild soap as needed.
- Do not immerse the earmuffs in water or use harsh cleaning agents.
- Allow ear cushions to air dry completely before use.
6.2 Replacing Ear Cushions
Replace ear cushions when they show signs of wear, cracking, or reduced sealing effectiveness.
- Gently peel off the old ear cushions from the earcup.
- Align the new ear cushions with the earcup and press firmly around the edges until they are securely attached.
6.3 Battery Replacement
Replace batteries when the earmuffs no longer power on or the sound amplification becomes weak or distorted.
- Follow the battery installation steps in Section 4.1.
- Dispose of used batteries responsibly according to local regulations.
7. Troubleshooting
If you encounter issues with your PROHEAR Electronic Shooting Earmuffs, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/Earmuffs do not turn on | Dead or incorrectly installed batteries | Replace batteries with fresh AAA batteries, ensuring correct polarity. |
| No sound amplification | Volume too low; Batteries low; Microphones blocked | Increase volume. Replace batteries. Ensure microphones are clear of obstructions. |
| Poor noise reduction | Improper fit; Worn ear cushions | Adjust headband for a snug fit. Replace ear cushions if damaged or worn. |
| Bluetooth not pairing | Earmuffs not in pairing mode; Device Bluetooth off | Ensure earmuffs are on. Turn Bluetooth off/on on your device. Try re-pairing. |
