Innovative design, the first foam earplug featuring a cylinder shape
The 3M™ E-A-R™ Classic™ Earplugs set the industry standard for personal safety noise reduction as the worlds first foam earplug. Soft, slow-recovery foam is designed to mold to the shape of the ear canal and provide hearing protection. These disposable earplugs come with or without cords; an optional dispenser box is sold separately. A cylindrical shape is suited to fit most sizes, with a 7% smaller version also available for smaller ear canals and a 20% longer version for larger ear canals.

Innovative design
The first foam earplug featuring a cylinder shape. Even in humid environments, the moisture-resistant foam helps provide more comfort.
