3M E-A-R Switch Protection earplugs are designed for insertion into the ear canal and help reduce exposure to hazardous sounds, with constant reduction and peak reduction options. They feature a special acoustic filter that lets through lower noise levels with relatively low noise reduction, for greater environmental awareness, and increasingly strong peak reduction at noise levels above 110 dB.
