SureFire EarPro EP3 Sonic Defenders | Earplugs for Hearing Protection


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. Available in clear or black.

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 no longer provides hearing protection once the Hocks Noise Braker filter has been removed.

EP3 Sonic Defenders are sold as a single left/right set or in a box containing 25 sets. Each set is packaged in a convenient carry case and includes a polymer lanyard.

EP3s are available in small (S), medium (M), and large (L). Proper size is based on the dimensions of your ear's concha bowl. Size "medium" fits most people; however, to ensure the best possible fit, review the earpiece sizing chart provided. For those with larger ear canals, the EP4's three-flange stem may provide a better fit than the EP3's two-flange stem.

    Solid ear pro

    Posted by Ben Wilson on 21st Jan 2022

    For the price these are great earplugs. No complaints. They still will fit under any over the ear protection if you want to have it really quiet. Arms Unlimited is always very quick to deliver.

    Hard plastic bites into ears

    Hard plastic on outside of earplugs but into ears and makes prolonged wearing difficult.

    Great earpro

    Posted by Matt on 20th Jul 2021

    These things are great. I have owned many pairs, and used them for years. I'd stay away from the foam tip ones, for ease-of-cleaning reasons, but they work great just like the others. They have a tiny piece in them small enough to be moved by sound waves, so when a loud enough sound (gunshot) hits that piece, it closes the little open sound tunnel for just split second, saving your hearing. They don't have the highest decibel reduction rating, but they are perfect for outdoors shooting.
