EP7 Sonic Defenders® Ultra

Filtered Foam-Tipped Earplugs

Hover on image to zoom



I am in Afghanistan and train men on automatic weapons and AK's. What a Blessing to have these protectors! They are small enough to store when not using them and while in use, they fit so comfortable that I sometimes dont even feel them.
Thanks for the great product.

They work well and fit properly, but to my ears there isn't much difference between them and a cheap disposable pair of foam ear plugs with the same or better NRR rating. Customer service told me these have a 40+ dB NRR with the auxiliary plugs inserted even though I questioned that. On arrival, I found my questioning was well-founded, being 28 dB with filter caps inserted. Nowhere near the 40+ I was told. I plan to go back to electronic earmuffs that don't require expensive foam tip replacement every 2-4 weeks (as stated). This is just one of those "better mouse trap" gadgets that gets the job done for sure, but isn't worth the hassle and added expense from my viewpoint.

Time Attack and Auto X

Work great while wearing a Snell Approved Helmet. I can now spend a day at the track and hear what people are saying the next day. Vast improvement.

These work great. I've worn them at an outdoor range firing pistols and AR's with no problems. The canal tips do a great job of filling in the ear canal so all noise goes through the filters. These are now worn at work. It's great to ear my prep radio on traffic stops. I can also have normal conversations in the car and hear car radios. I'm highly confident that a major problem ever arise (i.e. shootout), my hearing will not suffer.

These are the very first plugs I have had in the past 10 years that fit absolutely perfect! They stay in place and they work! Thank you, SureFire!!

Definitely worth having. Forget you even have them on when under heavy machinery or at the range.

Seems like a good product. Unfortunately, the small size is still too large for my ear canal. Bought two...back to the drawing board.

Great protection and fit

I added EP7s to my EP collection. I have several other but I prefer the maximum noise protection and like to plug the canals fully for competition and keep them open for practice. Great protection and thanks for the extra set of foam plug covers.

New use

After I talked to support and found that the ear piece was stretchable, I was able to remove the central plug and attach ear buds to each side. Now I can ride my jet ski at 45 mph, with the ear buds and shooting ear muffs, and I hear the music perfectly clear and almost no engine or wind noise. What a great improvement.

EP7 product

Took the new EP7's to the gun club last weekend. Product is not satisfactory ear protection on the skeet field. I had to put them aside and use my old hard "headphone" type protection.

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.
