3M™ E-A-R™ TaperFit™ 2 regular -size uncorded foam earplugs feature smooth foam that expands in the earcanal to help provide comfortable hearing protection. Soft, roll-down foam earplugs with a tapered design expand to fit the ear canal and provide a low-pressure, comfortable seal for a barrier to noise. Poly bag keeps polyurethane foam earplugs clean before use. Noise Reduction Rating (NRR) is 32 decibels. CSA Class AL. *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.
