SureFire EP4 Sonic Defenders Plus Filtered Earplugs Medium

SureFire EP4 Sonic Defenders Plus provide advanced hearing protection without interfering with your ability to hear routine conversations and environmental sounds. Featuring a proprietary noise-reducing filter, they block potentially hazardous sounds above 85 dB while delivering a 24 dB Noise Reduction Rating (NRR) when the attached filter caps are inserted.

Crafted in the USA from hypoallergenic, medical-grade polymer, these reusable earplugs utilize patented EarLock retention rings with seven contact points for a secure, all-day fit. Their low-profile, triple-flanged design integrates seamlessly under helmets, masks, and supplemental hearing muffs, and they can also convert into communication earpieces for compatible radio systems.
