Your hearing health matters. The SureFire EP4 Sonic Defender Plus earplugs protect against Noise-Induced Hearing Loss (NIHL). They let you hear everyday sounds and conversations, even in noisy places. With a triple-flanged stem, these earplugs provide a Noise Reduction Rating (NRR) of 24 dB. Safe sound levels pass into your ear canal. Our noise-reducing filter cuts harmful noise above 85 dB. The EP4s include filter caps for extra protection when needed, like on an aeroplane or when ambient sounds do not matter. Sonic Defenders are made from soft, durable, hypoallergenic polymer. They are comfortable for all-day wear and last up to 6+ months with proper care.
