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.

• 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
• 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
• 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.*
• 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, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding
• CLEAN STORAGE: Poly bag keeps earplugs clean before use, and cord allows earplugs to be stored conveniently around the neck in between uses
• For industrial/occupational use only. Not for consumer sale or use
