Earmuff is a sort of personal protection equipment that protects the wearer's ears from loud noise, dust, and temperature changes, particularly cold. This product is designed like a pair of cups and is composed of thermoplastics and a sponge. This is very effective as well as economical and safe to use. Earmuff will do the job in most cases, but it may be uncomfortable in hotter climates. This, on the other hand, is designed to fit directly into the ear canal and provide optimum noise protection.
