SureFire EarPro EP3 Sonic Defenders

EP3 Sonic Defenders were named the 2011 Safety Product of the Year at the 20th Annual Shooting Industry Awards.

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 they also block out lower-level noise like that heard on a plane.

They can be used in situations 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. Each set is packaged in a convenient carry case. Available in clear.

*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.

*All sizes of EP3s have identical flanged ear canal stems—that is, the portion that fits in the ear canal.

*The sizes—small, medium, and large—refer only to the outer earpieces that fit in the ear's concha bowl and help hold the EP3 in place. Proper EP3 size is based on the dimensions of your ear's concha bowl. Medium fits most people.

*For those with larger ear canals, the EP4's three-flange stem may provide a better fit than the EP3's two-flange stem. [NSN: 6515-01-549-6448, 6515-01-549-6453, 6515-01-549-6457]

    Good Product

    These are exactly what I was looking for, they are comfortable and do the job for outdoor ranges. Not sure for indoor. Cost is really not an issue, it's way cheaper than hearing aids.

    Comfortable hearing protection

    Posted by BB on 15th Aug 2016

    I use these earplugs when I go duck hunting. They are comfortable so I don't really notice that I'm wearing them (and am hence more likely to wear them). They allow enough sound to get through that I can talk with the guy next to me and I don't have to worry about ringing my ears when the birds do show up.

    Great Protection

    My order arrived quickly. Feel the price could be less though, after all it's only injection molded plastic!

    Not enough!

    Posted by Unknown on 21st Dec 2015

    While these fit without problem they did not provide enough hearing protection. A rifle with a muzzle break is just too much for these, especially if firing underneath a covered area. Will stick with the electronic ear muffs and try these for handgun out in the open.

    Ok plugs

    Posted by Kelly Burton on 3rd Apr 2015

    I took these to our indoor range and they were not enough sound protection for me to shoot comfortably. Will try them at the outdoor range next.
