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.

A MUST have!

These are truly one of the best hearing protection one can get. Very comfortable even after long hours of wear and it works great reducing the noise. I have tried many different inside the ear hearing protection products through out the years and these EP7 are the best in the market.

Very comfortable

I exclusively use my Sonic Defender's when performing my yard work. They are easy to put in and almost invisible. Significantly lowers the noise level from my weed trimmer/edger and lawn mower. I could wear these all day.

Works as advertised. Very easy to use.

I received the EP7 Sonic Defenders Ultra with great anticipation.

I ordered the small size reasoning they would best fit my ears.

Indeed, after experimenting with the foam tipped earplugs to obtain what I believe to be the best fit; I was disappointed to find that the sound of my 1911 firing at the indoor range penetrated more than I expected.

In fact, I simply put the normal headset ear protection provided by the range over the ear plugs to obtain great protection from the blast of each round fired.

It may be possible that the regular size earplugs would work better after all, but I am not inclined to pursue the 'experiment' further.

I simply purchased a different type of ear protection offered by the NRA.

Too bad, I had hoped for more complete ear protection from this attractive design.

I've tried a lot of different hearing protection, from foam plugs to custom fit. The EP7's are comfortable and allow for normal conversation to come through. For long duration exercises, the fit and low profile are perfect.

Get what you paid for

I ordered these because I was tired of the conventional earplugs. These worked greater than I could have imagined. They do a great job of keeping my hearing protected while shooting and other loud activities, whilst also letting me be aware of the more quieter noises around me, like people talking. Great product. Thanks, Surefire.

Only Hearing Protection I Will Use

I decided to try several types of earplugs offered by Surefire including the EP7's since I can not comfortably wear over the ear protectors. The EP7's are now the only type of hearing protection I will wear, especially at the range. They fit comfortably, provide excellent protection (sound reduction) but still allow me to hearing other people very well.

Fitting is very easy since the ends have a compressible foam tip that expands back to fill the ear canal and remain in place unlike the EP8's I tried.

Outstanding Product!

I am a Small Arms Master Gunner & instruct many types of weapon systems, previously with the Surefire EP5's. A great product, but seemed to come unseated with sweat & extreme movement for me. The EP7's stay seated & comfortable while protecting against dangerous noise levels well above 100 decibels no matter the conditions!
I highly recommend these to all serviceman for any live fire situation, Surefire is not just cool gear name to drop, it's top shelf quality that you can trust & believe in.
