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.
SECURE: Exposed cell surface texture resists movement and helps maintain an effective seal creating a comfortable, snug noise barrier. Noise Reduction Rating (NRR) 33 dB. CSA Class AL. *
OUTSTANDING COMFORT: This unique slow-recovery, low-pressure foam and special cylindrical shape help enhance comfort throughout the day by creating lower pressure in the ear canal.
LONGER SIZE: Classic Plus ear plugs are 20% longer than the regular E-A-R Classic ear plug (and the same diameter) to fit deeper into the ear canal and help provide higher noise reduction.
SOFT SOUND-ABSORBING FOAM: Proprietary foam is initially firm to make fitting the ear plug easier, then softens once it’s in the ear to comfortably conform to the unique shape of each ear canal.
SWEAT AND HUMIDITY RESISTANT: Classic ear plugs are resistant to moisture absorption for consistent fitting even in humid environments.
VERSATILE: Use while chipping, chiselling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding.
For industrial/occupational use only. Not for consumer sale or use.
