Ear muffs are simple to remove and replace, which makes them ideal for intermittent applications. Ear muffs are more likely to provide the rated protection because they cover the entire ear, so you do not have to worry as much about proper fitting. Ear muffs are more sanitary than inserted plugs because they remain outside the ear, which makes sharing ear protection a safer alternative. Ear muffs are also generally more comfortable than most alternatives because nothing is inserted in the ear canal.
