Product description

Product Description

Surefire EP4 Sonic Ear Defenders (Pair) 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 Ear Lock 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. 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 will not provide hearing protection if the noise-reducing filter is removed. * RADIO COMM SYSTEM COMPATIBILITY: • Thales: Covert Security Harness • Harris: Security Force Communication Set • Motorola: Surveillance Kits • Tactical Command Industries: Tactical Earpiece Products • Peltor: Lightweight Systems-Hearplug • Silynx: C4Ops Headset

Noise-reducing Filters

Filtered Sonic Defenders use established, non-electronic technology to reduce dangerous noise while allowing the hearing of safe-level conversations, commands, and ambient sounds.

1. Loud, potentially harmful sound waves enter the filter.

2. Sound waves above 85dB hit the ridges inside the filter.

3. These sound waves reflect off the ridges of the narrowing walls and cancel themselves out.

4. Dangerous sound levels are reduced, and safe levels pass through.

5. The louder the sound, the more noise gets cancelled.

Patented Earlock Retention Rings

SureFire Sonic Defenders feature our innovative EarLock outer rings, which lock the earplugs in place with seven unique grab points (see image above).

A low-profile design allows for easy wearing under a hat, helmet, mask, headset, supplemental muffs or even while using the phone.

Radio System Earpiece Use

With its noise-reducing filter removed, an EP4 earplug can be used as a comfortable, high-performance earpiece with many popular radio communication systems.

SYSTEM COMPATIBILITY: Thales Covert Security Harness, Harris Security Force Communication Set, Motorola Surveillance Kits, Tactical Command Industries Tactical Earpiece Products, Peltor Lightweight Systems-Hearplug & Silynx C4Ops Headset.

EP4 Sonic Defenders Plus typically last up to 6+ months, depending on usage and care.
