Block The dB. Hearing protection isn’t a game. It’s crucial to the prevention of Noise Induced Hearing Loss (NIHL). Affordable, reusable, full-block EP5 Sonic Defenders® Max earplugs utilize a soft, adjustable, triple-flanged stem to seal the ear canal and block out potentially harmful sounds, providing an impressive Noise Reduction Rating (NRR) of 26 dB. They are an excellent choice for industrial, tactical, and general applications where maximum protection against continuous noise is a priority over hearing ambient sounds or conversations.* EP5s are made from a soft, durable, hypoallergenic polymer for all-day comfort and extended life (up to 6+ months, depending on usage and care). A low-profile design allows them to be worn with a mask, helmet, or supplemental hearing muffs. You work in an industrial space. Give your ears industrial-strength protection.
