SureFire EP4 Sonic Defenders Plus Earplugs (Large, Clear, 1 Pair)

The large, clear 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.
