1. Introduction and Overview
The ProCase Noise Reduction Ear Muffs are designed to provide effective hearing protection in various noisy environments. Constructed with a solid ABS shell and thickened foam, these ear muffs achieve a Noise Reduction Rating (NRR) of 28 dB and a Single Number Rating (SNR) of 34 dB, certified by ANSI S3.19 (US).
They feature a flexible and ergonomic headband with 360-degree rotatable ear cups, allowing for adjustment to fit most head sizes, from children to adults. The soft padded headband and generous space within the ear cups ensure comfort and breathability during extended use. A compact folding design facilitates easy storage and portability.
These ear muffs are suitable for a wide range of activities including lawn mowing, shooting, construction work, sporting events, studying, factory environments, woodworking, and for individuals with autism who require sensory noise reduction.

2. Setup and Adjustment
Proper adjustment of your ProCase Noise Reduction Ear Muffs is crucial for both comfort and effective hearing protection.
2.1 Adjusting the Headband
The headband is designed to be flexible and adjustable to accommodate various head sizes. To adjust, gently pull the metal rack on each side of the headband to extend or retract the ear cups. Position the ear cups so they fully cover your ears, creating a snug seal. The ear cups can rotate 360 degrees to allow for optimal positioning and fit.

2.2 Initial Fit Considerations
For efficient sound isolation, the earmuffs are designed to fit snugly. If the fit feels too tight initially, you may gently stretch the headband. This can be achieved by placing the earmuffs over a box or similar object for 1-2 days. This process helps to slightly loosen the headband for improved comfort without compromising the noise reduction performance.
3. Operating Instructions
The ProCase Noise Reduction Ear Muffs are intended for use in environments where harmful noise levels are present. They provide a Noise Reduction Rating (NRR) of 28 dB, which indicates the average amount of noise reduction provided when worn correctly.

4. Maintenance
Regular maintenance ensures the longevity and effectiveness of your ear muffs.
4.1 Cleaning

- Do not immerse the ear muffs in water.
- Allow them to air dry completely before storage or next use.
4.2 Storage
When not in use, fold the ear muffs into their compact form. Store them in a clean, dry place away from direct sunlight, extreme temperatures, and corrosive substances. This helps preserve the material integrity and foam cushioning.

5. Troubleshooting
If you encounter any issues with your ProCase Noise Reduction Ear Muffs, refer to the following common solutions:
5.1 Ear Muffs Feel Too Tight or Uncomfortable
- Cause: The earmuffs are designed for a snug fit to ensure effective noise reduction, which may initially feel tight.
- Solution: Gently stretch the headband by placing the earmuffs over a box or similar object for 1-2 days. This can help loosen the headband for improved comfort without compromising performance.
5.2 Insufficient Noise Reduction
- Cause: Improper fit or positioning of the ear cups.
- Solution: Ensure the ear cups are properly positioned over your ears, creating a complete seal. Adjust the headband to achieve a firm, yet comfortable, fit. Check for any gaps between the ear cups and your head, as these can significantly reduce noise attenuation.
5.3 Ear Cups Do Not Rotate Smoothly
- Cause: Minor debris or friction in the rotation mechanism.
- Solution: Ensure the rotation points are clean. Avoid forcing the rotation. If the issue persists, contact customer support.
