Foam earplugs are designed to conform to the shape of a shooter's ear, so they won't fall out, but many shooters often remove an earplug to better-hear a friend or range-safety officer throughout their shooting session.  What happens if you lose that one plug? With the Walkers Corded Foam Earplugs, you don't have to worry about that situation, since these plug pairs are tethered to each other at all times. The plugs provide 32 decibels of sound reduction, and the 24-inch cord won't get in the way of your shooting setup.
