The 3M E-A-R Flexible HA Fit Earplug has a soft foam tip and a flexible fitting stem that allows easy insertion into the ear using one or two hands. The foam tip conforms to the unique shape of the ear canal to help block out noise. The Flexible Fit Earplugs are well suited for activities that require gloves or cause dirty hands or situations when only one hand is free to fit the earplugs.
