*U.S. EPA specifies the NRR as the measure of hearing protector noise reduction. However, 3M makes no warranties as to the suitability of the NRR for this purpose. 3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations or guidance on how to adjust attenuation label values. It is recommended that the NRR be reduced by 50% to better estimate typical protection
Vinyl or cloth material options for cords

3M™ E-A-R™ UltraFit™ Earplugs are made with a triple-flange design to contour to the different shapes and sizes of ear canals to help create a comfortable noise-blocking seal. These earplugs are made of a pliable, soft polymer that can be washed so that the earplugs can be reused, cutting down costs and extending the product life.

The 3M^™ E-A-R^™ UltraFit^™ Silicone Corded Earplug features a “no-roll”, triple-flange design that provides quick, clean, and comfortable hearing protection. Simply hold the stem and push the earplug into the ear.

The tip stays clean even if hands are dirty or gloves are worn. The earplug is washable and reusable so it doesn’t need to be replaced as often, reducing waste and lowering costs. Individual plastic carrying cases keep earplugs clean prior to use. Recommended applications include assembly and mechanical, chipping, chiseling, cleaning, drilling, furnace operations, grinding, heavy equipment operations, machining, metal repair, painting, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: construction, general manufacturing, mining, oil and gas, and transportation.

These earplugs have a Noise Reduction Rating (NRR) of 25 dB and are test compatible with the 3M^™ E-A-Rfit^™ Validation System.

Not only is noise present in our daily routines and recreational activities, but millions of Americans work in hazardous noise on a daily basis. 2015 estimates from the National Institutes of Health suggest that hearing loss afflicts 28 million Americans. About one third of those cases are at least partially attributable to noise. Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection.
