3M™ E-A-R™ Classic™ Earplugs have set the industry standard for noise reduction as the world's first foam earplugs. These earplugs are made of a proprietary soft energy-absorbing slow-recovery foam that's designed to conform to the shape of the ear canal to help provide hearing protection.

*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.;CSA Class AL;Compatible with the 3M™ E-A-Rfit™ Validation System;Dispenser packaging option available for uncorded earplugs;Features a Noise Reduction Rating (NRR)* of 29 dB;Moisture-resistant foam;Pillow pack option for storage of earplugs between uses;Proprietary soft, slow-recovery foam is comfortable and helps with earplug fitting
