Surefire
EP3 Sonic Defenders protect your hearing without interfering with your ability to hear routine sounds or conversations. Their double-flange-stem design fits most people 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 the patented Hocks Noise Braker® filter. EP3s include attached stopper plugs, which can be inserted for further protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. The right/left color-coded Sonic Defenders are made from a soft but durable, hypoallergenic polymer and are ergonomically shaped, with an adjustable-stem design, providing a secure fit, all-day comfort, and extended product life (3 to 6+ months, depending on usage and care). And their low-profile design means they can be worn while wearing a helmet or mask, or while using a phone or headset.
Comfortable EP3 Sonic Defenders also serve as earpieces for EarPro by SureFire® and other compatible radio communication systems*simply by removing the Hocks Noise Braker filter and attaching the earpiece to the system. NOTE: EP3 earpiece will not provide hearing protection if the Hocks Noise Braker filter is removed.
Sizing is based on the dimensions of your ear's concha bowl. Size "medium" fits most people; however, to ensure the best possible fit use the measuring chart in the pictures above. For those with larger ear canals, the three-flange stem of our EP4 Sonic Defenders may provide a better fit than the EP3's two-flange stem.
For best fit, click on the small Sizing Chart image above.
EP3 Sonic Defenders are sold as a single left/right set. Each set is packaged in a convenient carry case and includes a polymer lanyard.
