SureFire EP4 Sonic Defenders® Plus
Filtered Flanged Earplugs
EP4 Sonic Defenders® Plus protect your hearing without interfering with your capacity to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and supplies a Noise Reduction Rating (NRR) of 24dB. Sounds, at stable levels, are permitted to pass through into the ear canal, although potentially harmful noises (above 85dB) are reduced through a proprietary design that incorporates a particular noise-reducing filter. EP4s contain attached filter caps, which can be added for additional protection and blocking out lower-level noise, such as that heard on a plane, where hearing nearby sounds or conversations is not critical. Right/left color-coded Sonic Defenders Plus are made from a soft yet durable, hypoallergenic polymer that provides all-day relaxation and an elongated product life (up to 6months, based on care and usage ). Their patented EarLock® retention rings lock the earplugs in place, while soft, adjustable triple-flanged stems provide secure seals at the ear canals. A low-profile design signifies EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. Offered in black, clear, or orange.
Cozy EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer supplies hearing protection once the noise-reducing filter has been removed.
EP4s can be located in small (S), moderate (M), and large (L). Proper size is based on the dimensions of your ear's concha bowl. Size"moderate" fits many men and women. For those with smaller (in diameter) ear canals, the two-flange stem of our EP3 Sonic Defenders might offer a better match than the EP4's three-flange stem.

EP4 Sonic Defenders Plus are sold as one left/right place or inside a box containing 25 sets. Each set is packed in a convenient carry case and includes a polymer lanyard.
