The 3M™ E-A-R™ Classic™ Corded Earplugs were the world’s first foam earplugs and are still one of the most widely used earplugs today. Slow recovery, low-pressure foam fits snugly to create a noise barrier that helps protect hearing from loud sounds. These earplugs are moisture-resistant. Bright yellow colour allows supervisors to conduct a quick visual hearing protection compliance check.
