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 DefendersA(R) 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.
