SureFire EP7 Sonic Defenders Ultra Earplugs

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 black.

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.

    These earplugs work well. They allow for conversation while in and live fire around you. If you need additional hearing pro, you plug the hole and it reduces the noise input. The earplugs are comfortable and easy to use. A very good ear pro solution for a reasonable price in my opinion.

    Very Good Ear Plugs

    Posted by Rich on 10th Aug 2018

    I've been using just regular foam plugs to double up with my muffs, but find that they don't stay in very well. I've tried other plugs with the plastics tips, but uncomfortable. These plugs have the foam tips and they work perfectly for me. No problem staying in and allows me to remove the muffs when off the line, but not lose any hearing protection.

    Not as durable as EP3's

    Posted by Dan O on 16th Jan 2018

    These things are very good step up from those cheap "disposable" ones. However, the adhesive that holds the expanding foam on the canal portion of the earpro will give out with climate and temperature variations. Personally, I would opt for the EP3s. I've had and used them both for the same amount of time until the EP7s gave out. That being said, it's my opinion that these offer superior hearing protection over the EP3s. If you're looking to buy two pairs, try one of each.

    Posted by John DiPaula on 8th May 2017

    From the picture, i thought they were something special but, found out they are just ear plugs. I won't waste my money on them ever again.

    I never used these until a recent competition shoot. They were great at blocking noise and are very comfortable to wear all day. LCDR J. Baker Fox Co/2BN/TMAR Texas State Guard

    Not sure if they fit correctly

    Posted by Tony on 8th Jun 2016

    I got size medium because I was unsure of what size I should've gotten. I went to an indoor range and my ears were ringing afterward. Either need a bigger size or they just don't offer me enough protection
