The medium, orange EP4 Sonic Defenders Plus Earplugs from SureFire provide an EPA Noise Reduction Rating (NRR) of 24dB, with pass-through triple-flanged stems. This flanged system is designed to fit individuals with larger ear canals, and can offer better fit and protection than the comparable EP3 Sonic Defenders double-flanged stem. The stems filter loud potentially harmful noises over 85db while allowing safe, lower-level sounds, such as conversations, to be heard. The attached filter caps can be inserted into the stems for full protection from all sound. They can be used as 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 to wear all day. The EarLock design fits flush in the ear with 7 points of contact to keep them locked in place. It also 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 a carrying case is included.
