EP7 Sonic Defenders Ultra

Got these to shoot a .308 with a muzzle brake at an out door range. Noise canceling more than adequate, voice levels not near as good as electronic headphones, but well worth it for getting a comfortable cheek weld on the stock without headphones getting in the way. I love them, need more!!!

I. Have very small ears, so even the small size became very uncomfortable after awhile. I didn't notice any difference with or without the little plug opened or closed. I liked them, but couldn't wear them for very long. I wish you had an XS size. Then they'd fit children better, too. I'm a race track photographer, so need to hear people talking during the races, which are very loud. If these fit me I'm sure I'd love them.

EP7's not too bad

The first few time you put them in your ears are a pain. After that they go in pretty easy. I shot indoors and outdoors with them. Left the plugs out to see how loud things were. I could hear people talk just fine, muffled pistol and rifle rounds very well. They preformed the same indoors and out. Just wished they came with a case, the one that it comes with doesn't stay shut very well. That's the only down side.

The Iron Curtain of ear protection.

These things are great. I used to wear the foam style that you twist up and stick in your ear. So annoying. These are comfortable, I forget I even have them in. I use them for shooting and also for my radio when playing airsoft. They work flawlessly in both situations. They let in just enough noise to still allow you to hear people talking to you. Now I have two pairs, one just in case my others get lost.

While the fit is comfortable and they do work as expected with the plug in the end, I was disappointed to find that when I would take the plug out to allow voice-level sounds to come through, they didn't work as expected & were the same with or without the plug installed.

I still like the design & use them for recreational shooting - they're not bulky like other headphone-style hearing protection (the electronic kind that cut out at about 80dB but have microphones to allow "normal" hearing at lower decibels) that I've tried. May have to do some more experimenting to see if I can get them to work as advertised...

works as described. They become uncomfortable because of the pointed ear tip, so I cut it off. Much better now.

Best hearing protection

Ultimately the best hearing protection on the market. I am a hunting and shooting enthusiast who had been looking for a comfortable and reliable pair of ear buds. My search has ended! They are easy to install, comfortable and definitely cancel out the noise made from gun fire. Would recommend them to anyone looking to protect their hearing.

These are great at the range. So much better than the full head Peltors I used to wear to get voice minus shots, especially in Florida where heat and sweat are a given. Buy a pair!

These are hard to rate because I have a small ear canal - and these do not fit into my ears. I have used other Surefire plugs and have liked them but these do not work for me. I'm sure they would be great for normal size ears!

to be honest , I'm a little disappointed (especially for the cost )
It seems like I can get just as much noise reduction from those
foam plugs that you roll between your fingers and insert. for
fifty bucks, I could have bought a whole lot of those !!!

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.
