Surefire EP3 Earpro Sonic Defenders Medium Plugs 24 Db NRR Clear The medium, clear EP3 Sonic Defenders Earplugs from SureFire provide an EPA Noise Reduction Rating (NRR) of 24dB, with pass-through double-flanged stems. The stems filter loud potentially harmful noises over 85db while allowing safe, lower-level sounds, such as conversations, to be heard; and for full protection from all sound the attached filter caps can be inserted into the stems. They can also be used as inconspicuous earpieces for compatible radio systems by removing the filters. With the filters removed, the earpieces will no longer protect against noise. Made from a soft medical-grade hypoallergenic polymer, these hearing protectors are comfortable for all-day wear. The EarLock design fits flush in the ear with 7 points of contact to keep them locked in place, and allows them to be worn with helmets and masks, or while using a phone or over-the-ear headset. A detachable 26" polymer lanyard keeps them together and each pair comes with an individual carrying case. Features: - Max.
