Earmuffs Only

Directions for use

  1. Pull cups outward and position so the cushions fully enclose the ears while sealing tightly against the head.
  2. 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.


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 muffs regularly with soap and lukewarm water. Do not immerse in water. Do not store muffs in temperatures above 130° F (55° C). Muffs should be regularly inspected for cracked or worn parts and replaced as needed. Typical life for foam muff cushions is 6 months.

Earplugs Only

Directions for use

  1. With clean hands, hold earplug between thumb and forefinger. Roll and progressively compress the entire tapered end of the earplug to a small wrinkle-free cylinder.
  2. To ensure fitting, reach hand over head and gently pull ear upward and outward.
  3. Insert compressed, tapered end of earplug well inside ear canal. Hold 30 - 60 seconds until earplug expands. Release, then push in again for 5 seconds to ensure fit.
  4. Remove earplug slowly. Use a gentle twisting motion to gradually break the seal. Rapid removal may damage eardrum.

Discard after several uses or as soon as dirt or wax accumulates on earplugs.

User fit check

In a noisy environment with earplugs inserted, cup hands over both ears and release. If the earplugs are inserted correctly, you should not notice a significant difference in attenuation. If a proper fit has not been obtained, move to a quiet area and repeat fitting instructions.


  • Remove earplug slowly with twisting motion to gradually break the seal. Rapid removal may damage eardrum.
  • Improper fitting will reduce effectiveness and could result in hearing loss or injury.
  • Keep away from infants and small children. These earplugs are non-toxic, but may interfere with breathing if caught in windpipe, which could lead to serious injury or death.

Earmuffs And Earplugs Together

Directions for use

Place earmuffs carefully on head after earplugs have been inserted. Refer to Directions for Earmuffs Only and Earplugs Only for proper fitting procedures.

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 bulky and uncomfortable, like others I've tried?
Because these earmuffs are low-profile, lightweight, fully adjustable and feature a padded band, 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.
