DIRECTIONS FOR USE
- Pull cups outward and position so the cushions fully enclose the ears while sealing tightly against the head.
- Adjust the height of each cup equally on both ears while holding headband on crown of head to create a snug and comfortable fit. With earmuffs over both ears, push cushions towards head.
If there is not a noticeable difference in noise level, earmuffs are probably not fitted properly. To obtain proper fit, repeat fitting instructions.
Warnings & Precautions
WARNINGS: Noise reduction is adversely affected by anything that impairs the seal of the earmuff cushions. Improper fitting will reduce effectiveness and could result in hearing loss or injury.
Care and Cleaning Instructions
Clean outside of earmuffs occasionally with mild soap or disinfectant and a damp cloth only. Do not immerse in water. Do not store muffs in temperatures above 130° F (55° C) or below 32°F (0° C). Exposure to or contact with certain chemicals or vapors may cause damage to this product. Earmuffs should be regularly inspected for cracked or worn parts and replaced as needed. Typical life for foam muff cushions is 6 months
Why is it always a good idea to wear ear plugs and earmuffs together?
The practice of wearing two layers of hearing protection simultaneously is called “Doubling-up.” Hearing protection is often improperly applied/worn, and wearing safety glasses, “butting up” or head or facial hair can sometimes allow noise to incidentally sneak past the cushioned seals on earmuffs. By doubling-up with earplugs and earmuffs, the user has an added layer of protection to help minimize the harmful effects of incidental noise intrusion when it occurs. Incidental exposure aside, doubling-up increases noise reduction performance and maximizes the user’s protection factor. It’s your hearing. Protect it.
Will these earmuffs fit kids?
The earmuffs are adjustable and designed to fit kids to adults.
Are the earmuffs uncomfortable, like others I’ve tried?
These earmuffs are lightweight, fully adjustable and feature a padded band, so users find them very comfortable.
Do you offer replacement parts or hygiene kits for these earmuffs?
No, but the earmuffs can be cleaned by gently wiping them down with mild soap and water.
