EP4 Sonic Defenders Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 24dB. 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 Plus are made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to 6+ months, depending on usage and care). Their patented EarLock retention rings lock the earplugs in place, 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. Available in clear, black, or orange. Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed.

Made in USA from hypoallergenic, medical-grade polymer that's soft, durable, and long-lasting. Patented EarLock retention rings utilize seven contact points to lock earpieces in place and fit the same way every time. Low-profile design allows you to keep them in place while wearing a mask, helmet, hat, or while using supplemental hearing muffs. Soft, adjustable, triple-flanged stems provide secure seals in ear canals and all-day comfort. 24dB Noise Reduction Rating (NRR) with filter caps inserted, Hear safe sound levels (with filter caps out) as if you weren't wearing ear plugs.
