SuperFit earplugs are the only earplug model with a unique “fitting ring” to easily see when the earplug is correctly fitted. When no orange colour is visible, the best fit is achieved.
The soft, pliable foam on this uncorded foam earplug features an orange fitting ring that provides a guideline for proper fitting. Earplugs are easy to roll down and insert, then expand within the earcanal for a comfortable, secure fit. Poly bag keeps each pair of earplugs clean before use. Regular size fits most earcanals. Noise Reduction Rating (NRR)* 33 dB. CSA Class AL. Test compatible with 3M™ E A Rfit™ Validation System. *The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided. 3M is Leading the Advancement of Hearing Conservation™.
