3M™ E-A-R™ Classic™ uncorded 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 for higher noise reduction when fit deeply in the ear canal.

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. Slow recovery, low-pressure foam conforms to the shape of the ear canal to help create a comfortable, snug noise barrier.


  • Reusable Pillow Pack helps keep earplugs clean when they are not being worn
  • Classic™ Plus earplugs are slightly longer than regular E-A-R™ Classic™ earplugs to fit deeper into the ear canal and provide higher noise reduction
  • Flame-resistant (Important for potential arc flash situations and for storage considerations)
  • Moisture-resistant (Helps maintain a consistent expansion time, even in humid environments)
  • 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.
