Protect your hearing with the SureFire EP4 Sonic Defender Plus, designed to guard against noise-induced hearing loss (NIHL) while still allowing you to hear important sounds and conversations in noisy environments. Featuring a triple-flanged stem, these earplugs provide a noise reduction rating (NRR) of 24 dB. Safe sounds can pass through the ear canal, while potentially harmful noises (above 85 dB) are filtered out by our advanced noise-reducing technology. The EP4s also come with detachable filter caps for extra protection, ideal for blocking lower-level noises, such as those encountered on an airplane, while still allowing you to hear essential sounds. Made from a soft, durable and hypoallergenic polymer, Sonic Defenders offer all-day comfort and an extended lifespan of up to 6+ months with proper care.
