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.

Classic earplugs were the industry’s first foam earplugs, virtually revolutionising hearing protection. Today, the revolution continues. It meets more wearer and environmental needs with its proprietary foams, preferred cylindrical shape, and proven in-ear comfort.
