SmartFit(tm) earplugs from Howard Leight uses advanced materials that respond to the body heat inside the ear. No two people are alike and as SmartFit warms up, it takes on the unique shape of the surrounding ear canal to fit the wearer perfectly. SmartFit actually feels better the longer it’s worn, unlike traditional earplugs that feel okay at first and later irritate ears. Once removed, SmartFit returns to its original shape, ready to be used again and again. Laboratory tested NRR: 25dB. Compliance: ANSI S3.19-1974.
