Sonic Defenders

EP3's rock! These things are light, super comfortable and work really well at the indoor range. Just be careful that someone doesn't nab them; I've had several people ask me where to get there own! Ha!

I love these ear plugs. They are very comfortable; you hardly know you're wearing them.
I wouldn't suggest them for an indoor range - I'd probably still wear a big pair of ear muffs, but in the field, these are excellent.
Fit is perfect and the ability to still hear most sounds as if I wasn't wearing them is great.

Best & Comfortable

I bought these for work and they are the most comfortable in the ear and they work, great. Very happy. One of the best purchases I've made lately. If I need another pair I will for sure buy another pair. I would recommend anyone looking to get ear protection to get Sure Fire ear protection.

Every Day for The past 5 years

I have worn the Sonic defender 3 every day for the last 5 years,at work as well as the Army. I have never had such an effective pair of ear Plugs. Thank you for the great product.

Great Supplemental Protection.

These are very comfortable. I use these alone when I shoot suppressed for added protection. I also use these under my electronic muffs when training or at the range. I had an older pair from 3-4 years ago and recently misplaced them. I liked them enough I did not hesitate to order 2 more to keep in my bag.

another layer of protection

SureFire, I wanted to tell You how much of a difference the EP3s made for my wife. To be able to use her ear muffs at the range and still have a layer of protection to depend on at times when she wanted to talk and hear range commands. Now if her ear muffs don't fit just right, she doesn't have to worry about being without adequate protection. This is a good product and is what I have grown to expect from SureFire products. Thanks.

Good product

I use them whil riding motorcycle, to cut down on wind noise, inside the helmet. They are very effective for me. They allow me to hear normal traffic sounds. They fit well and are very comfortable, while wearing the helmet.

EP3 Sonic Defenders protect your hearing without interfering with your ability to hear routine sounds or conversations. Their double-flanged-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 a special noise-reducing filter. EP3s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders 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, adjustable double-flanged stems provide secure seals in the ear canals. A low-profile design means EP3s can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange.

Comfortable EP3 Sonic Defenders also serve as earpieces for SureFire Hearing Protection and other compatible radio communication systems* simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP3 earpiece will not provide hearing protection if the noise-reducing filter is removed.

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, click on the Sizing Chart thumbnail image above or download detailed specifications here to also view the sizing chart on page 4. For those with larger (in diameter) ear canals, the three-flange stem of our EP4 Sonic Defenders may provide a better fit than the EP3's two-flange stem.

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.
