Great Product

Being a law enforcement officer and having to qualify multiple times a year I needed something that was efficient and reasonable in price. The EP4 Sonic Defenders Plus have really done the job. Barely noticeable when wearing them and do a great job to block out the noise but not to much to where you can't hear verbal commands. Everybody was really impressed with them that a lot of my fellow officers and the range guys are looking to pick up a pair or two.

Flexible and effective shotgun sports ear protection

I shoot sporting clays and skeet. I have had the EP3 in a medium for a while but was not 100% happy with the fit, especially since I have differences in ear fit between left and right. The right has never been tight and I was always fiddling with it. I ordered 2 pair of EP4, one medium and one large. I use the large on my right and the medium on my left. The triple flanges work much better than the EP3 double flanges for both sides, and the large is a great fit for my right.

I can hear my shooting buddies and the traps throwing, yet get excellent BANG suppression.

I highly recommend the triple flangs EP4, and I it is a bonus that you can mix sizes if you have mixed ear bowl sizes like me

FANTASTIC Product

First discovered at work. A fellow employee was wearing them,given to her by her father to protect her hearing. As an avid shooter ear protection is mandatory. after trying several other products i bought my 1st pair of ep4s and was so impressed i bought several more pairs to give to my friends that i shoot with. Thanks Surefire for another fine product.

Fantastic for Oilfield

As a Soldier, these saved my hearing multiple times downrange and at a normal shooting range. Now, as pumper/lease operator for a well known oilfield company, I'm constantly around very loud equipment. These help me drown out the noise of compressors, but still allow me to listen for natural gas leaks coming from different types of equipment. A+ job, SureFire.

Great for Work, Good for Hunting, Not Good for Target Shooting

I got the Surefire EP4s for the purpose of hunting. In previous years I've used Sonic II plugs for hunting but I was looking for something that did a better job of allowing ambient noise in and were less likely to fall out. The EP4s fit great in the ear and stay where they are supposed to, and they let in more ambient sound than the Sonic IIs did, making it easier to hear wildlife walking in the woods. However, they don't work as well at cancelling out firearm blasts - my first test shot with a 12 ga. shotgun left my ears ringing. I wore them deer hunting in Maine and was very pleased with the comfort and ability to hear things around me, but I didn't get a shot that week to test out blast cancelation in a hunting scenario.

Since then I’ve worn the EP4s at work and am very pleased at the comfort and amount of loud noise that they keep out in the workplace while allowing me to hear other people talking. I sealed off the valves with the plugs (pretty much making them an EP5) and I can still hear what I have to without allowing damaging noise levels in (I have since gotten EP5s for this purpose but haven’t used them yet). The EP4s are so comfortable that I often leave work and forget to take them out until sometime later.

I don’t think these would ever work well for target shooting at the range – as it is I often use foam plugs plus muffs for that purpose, depending on what I’m shooting. I love them for the workplace and my overall analysis would be that they let in more sound than any other plug (such that I wear them more often and therefore protect my hearing more than I ever did before) but they don’t protect as well against louder sounds (such as firearms blasts). I recommend them for the lower ranges of damaging sound levels but not for the higher ranges. They are very comfortable and there is no need to worry about them falling out in the workplace or having them pulled out by a briar or tree branch out in the woods.

Thank you for the quick order respnse! I have not been able too test them yet due to limits on my time.
They fit great and am sure that they will out preform my old styroforms. I will get back as soon as I can use them.

EP4 Sonic Defenders Plus

Not good enough for stand alone protection. 45 ACP on up needs muffs to properly protect your hearing.

For detailed specifications, click here.

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.

EP4s 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. For those with smaller (in diameter) ear canals, the two-flange stem of our EP3 Sonic Defenders may provide a better fit than the EP4's three-flange stem.

EP4 Sonic Defenders Plus 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.
