EP7 Sonic Defenders Ultra protect your hearing without interfering with your ability to hear routine sounds or conversations. Their foam-tipped stem design, featuring soft memory-foam Comply Canal Tips, fits most people and provides a Noise Reduction Rating (NRR) of 28dB. 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. EP7s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, in situations where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders Ultra 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 foam-tipped stems provide secure seals in the ear canals. 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, black, or orange.

Comfortable EP7 Sonic Defenders Ultra also serve as earpieces for compatible radio communication systems* simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP7 earpiece will not provide hearing protection if the noise-reducing filter is removed.

EP7s 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 by clicking on the Sizing Chart image. EP7 Sonic Defenders Ultra 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 and an extra set of memory foam Comply Canal Tips; replacements available--see Parts and Accessories on this page.

All Day Comfort, Great Fit, Excellent Hearing Protection

I've tried lots of different in-ear and over-ear hearing protectors over the years, both passive and active. The Sonic Defenders are by far the most comfortable and versatile. I recently wore them for a week of shotgun and rifle range duty at Boy Scout Camp. They were comfortable, fit well, and provided excellent hearing protection, while allowing enough sound to pass through that I could instruct and help the Scouts with their shooting skills. I have three sets in different sizes. Make sure to get the correct size for your ear canal. I wore a different set for Sonic Defenders while taking a tactical course on the MP-5 and M-4 weapons systems. They suppressed the sound of 5.56mm fire well, did not get in the way during weapon transitions, and allowed for conversation with my partner - important when moving while engaged in live-fire. I wouldn't wear anything else.

Had these a few months now. They work well considering they don't cover the ear like head muffs do, but then I do not like muffs because all the ones I have tried start to hurt my head after wearing them for any length of time, whereas with Surefire's Sonic Defenders Ultra I have no such problem. Also, besides the comfort, they do a good job of protecting my hearing from gunshot noises, including magnum pistols.

These are the most comfortable hering protection device I have ever used. I would highly recomend them to anyone who works in a high noise environment, or on a gun range.

If you're anything like me, you don't like the large, bulky shooting ear muffs you typically see out there. Too often, ear "plugs" just don't block out enough noise, so for people like us choices are limited. These really fit the bill! Good noise reduction without the uncomfortable, sweaty and bulky effects of ear muffs! Best of all, at a fraction of the cost of ear muffs with similar noise reduction! I highly recommend - I truly enjoy wearing mine!

I got two sets one for my son and one for myself for shooting and working in the shop. Once you figure out how to fit them they go in great and stay in. From Trap shooting to cutting metal these are great. Thanks.

Great Hearing Protection!

These EP7 hearing protectors are about the most comfortable hearing protection on the market. I am a Range Safety Officer, and I use them 3-4 times a week for six to eight hours at a time. They are like not having anything in your ear yet not hearing any noise. I highly recommend these!

These hearing protectors are grade A products. My wife also has a couple of pair and they enable us to fire carbines, rifles, and shotguns without clunky electronic ears getting in the way. I highly recommend them and there will be some under our Christmas tree for sure.

EP7 Sonic Defenders Ultra

These ear buds are excellent protection. The fit is perfect and the removable filter is great. I actually shoot with the filter cap not inserted, they reduce the noise plenty and this way you can hear range commands or communicate with a friend better. I also like that the foam canal tips are replaceable. I have absolutely no complaints, quality is great as with any SureFire product.

SureFire EP7 Sonic Defenders

Works exactly as advertised, which makes this item a real bargain for the price. Sure beats those powered muffs. Occasionally, the retaining string got caught between my butt stock and my shoulder or cheek, which caused the earplug to pop out of my ear canal upon firing. Now I just pull the retaining string up under my hat. Problem solved.
