## Overview

SureFire EP4 Sonic Defenders Plus are premium reusable earplugs featuring a 24dB Noise Reduction Rating with advanced filter caps that reduce harmful noise while allowing safe sound levels to pass through. Their patented EarLock retention system and triple-flanged stems provide a secure, comfortable fit that stays put during active use. Designed with a low-profile shape, these hypoallergenic, medical-grade polymer earplugs fit seamlessly under helmets, masks, and headsets. Ideal for professionals and enthusiasts alike, they offer versatile noise control for shooting, commuting, and everyday noise protection.

## Description

EP4 Sonic Defenders Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals 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. EP4s 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 Plus 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 triple-flanged stems provide secure seals in the ear canals. A low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange. Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed.

Review: Great earplugs - So I bought these to use on my jet ski so the wind noise didn't destroy my ears thinking I could just pop the filter plug open and closed easy when needed. First off their super comfortable. For some reason I thought the "lock" or whatever it's called would be a hard rubber, but it's super soft and does a great job holding them in my ears. Even when I'm soaked from sweat and lake water. Easily the most comfortable plugs I've used, and they stayed locked in place the entire time I had them in. Unfortunately you need to take the whole plug out of your ear to easily open or close the filter. If you try to close the filter with them in your ear you're going to push the whole plug too deep and potentially hurt yourself, and while trying to open it with the plug in my ear I somehow managed to break the harness that holds them together. I also couldn't just leave the filter open while moving because they whistled like crazy. Only other minor complaint is that they're a little awkward to get in. The actual plug curves up compared to the locks, which probably helps with the comfort, but took me a bit to figure out and actually get into my ear canal. Overall I'm really happy with them, they worked okay on the jet ski. Cut out all of the wind noise but when we stopped to talk I had to pull one out to hear which was not ideal because they're a little weird to get back in. I'll be moving these over to my shooting ear pro where I know I'll love them because that's they're actual intended purpose.
Review: Very surprised at how well these work. - I wasn’t sure this “in the ear” plug would work as I hoped it would. I have tried many different types including battery powered and none seem to lower loud sounds as promised. I found them easy to insert in my ear with little or no discomfort the work very well. I used them for over an hour and was surprised how well the reduced sound levels. However, I wouldn’t want to wear them for long periods of time as I believe even these will start to cause some discomfort depending on your individual ear canal shape and size. I certainly like these better than wearing over the ear muffs. Well worth the price.

### ⭐⭐⭐⭐ Good product...comfortable, does reduce louder noises with passive reduction, durable, but not best match for all applications
*by Z***S on August 16, 2014*

I have been using the Sonic Defenders since the first generation. Since my first pair, these have improved consistently. Overall, I like the product. The primary design of this Ear Pro line is to reduce all noise, and reduce overly loud noises more so than ones of normal volume. It uses a passive design in which a valve on the ear plugs closes (from the sound wave) when higher volume noises or made, but is not closed by low volume things such as voices. To run these as a conventional ear plug, they come with valves you can close so that all noise is reduced. The two things most people seem more curious about is how well this product works, and how comfortable it is. My personal assessment is as follows... -effectiveness-the passive noise reduction does work, but may not work well enough for all users. For example, it reduces the sound of indoor gunfire to a point in which it is still a very unpleasant experience, but manages to reduce the sound enough to reduce the chance of hearing damage. This same situation outside (which will not be as loud) is a different story...these reduce the sound acceptably. So for inside usage, closing the valves may be necessary. -comfort-these are much more comfortable than easier generations. Still, application is key. Adjusting how deep the plug sits in the ear canal, as well as how well the frame rests in the ear, as well as that you have the right size, is absolutely critical to effective function and comfort. Once the above are given attention to, they are comfortable for prolonged wear of numerous hours. Cleaning these is a step that should not be ignored (otherwise, you could get an ear infection). I generally use alcohol to disinfect them, and break down any wax buildup. When used daily, I think these work work for at least a year when properly cleaned. If not properly cleaned, I think they tend to die earlier. So these are not magic, but I think a good product nonetheless. The passive noise reduction can be useful for many people, but it does have some limitations that may not make it the best choice for others.
