3M 311-1105 E-A-R Classic Corded Earplugs in Poly Bag NRR 33 - 200 Pairs

Overview:

3M™ E-A-R™ Classic™ corded foam earplugs set the standard in hearing protection as the world's first foam earplugs. Classic™ Plus earplugs are slightly longer than regular E-A-R™ Classic™ earplugs to fit deeper into the earcanal and provide higher noise reduction. Still one of the most widely used foam earplugs today, the 3M™ E-A-R™ Classic™ earplug is an economical, reliable choice in hearing protection and hearing conservation. Slow recovery, low-pressure foam conforms to the shape of the earcanal to help create a comfortable, snug noise barrier. 

Features:

• Classic™ Plus earplugs are slightly longer than regular E-A-R™ Classic™ earplugs to fit deeper into the earcanal and provide higher noise reduction.
• Flame-resistant and moisture-resistant.
• 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™.
