3M E-A-R Classic earplugs with a band

Earplugs made of polyurethane foam, with a cord or without it. They perfectly fit into any ear shape, thanks to their foamy texture. They are resistant to moisture, so they prevent moisture depositing in the ear canal. The texture of the surface prevents the earplugs from slipping and falling out. SNR is 28 dB. EN 352-2
