Made in the USA from soft hypoallergenic polymer, and utilizing a unique double flanged stem system, EP4 Sonic Defenders by SureFire protect your hearing without impairing your ability to hear ambient sounds and conversations. They fit most people well and provide a Noise Reduction Rating (NRR) of 24 dB. Sounds at safe levels are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced via a proprietary design that incorporates a special noise-reducing filter. EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical.
Right/left color-coded Sonic Defenders are comfortable enough for all-day wear. Their Patented EarLock retention rings utilize seven contact points to lock the earpieces in place and fit the same way every time while soft, adjustable triple-flanged stems provide secure seals in the ear canals. A low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset.
EP4 Sonic Defenders also serve as earpieces for SureFire Hearing Protection and other compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system.
