As someone who is x-military and was exposed to all kinds of intense noise and sounds, I owe your EP4's much thanks in keeping my hearing from being exposed to excessive sounds that could have damaged or impaired my hearing. Even now that I am retired and now work around loud machinery I still intrust my hearing protection to my EP4's Thank You!!

Comfortable and great working

I bought these to use at work, the EP3s were great, these EP4s are even better. I haven't had the opportunity to try the EP4s at the Range yet, but the 3s, with the plugs in, are just like wearing muffs. The EP4s are so comfortable, I've actually gone home with them still in. Only 1 fault I can find, and that's the case they come in. The 1st case fell apart after about a dozen uses. I would actually be willing to shell out a few more bucks for a durable holder for these very useful earplugs.

You Won't Be Disappointed

Got these a few months ago on a whim. I decided to go back to the earmuffs because the in the ear ear plugs were rubbing my ears raw constanty putting them in and pulling them out. When I found these I fugured I would give them a shot. Just buy them. It's totally worth it. They're comfortable and when youre out at the range you don't have to pull them out to talk.

Great for shooters

The little tab allows you to hear others commands while keeping gun shots from destroying your ears. The low profile stays out of the way and locks into your ear. I have never had them fall out. I bought all three sizes. The medium fits me great and I keep the other 2 sets sets for people who come over to shoot with no ear pro. Easy to clean with an alcohol wipe. I will buy another pair soon to have an extra set at work.

A Standout Product

I bought these back in February of 2013 and I have used them countless times throughout the year on the range. I shoot outdoors and outdoors only so I cannot speak for how well these do indoors. I can however tell you how awesome they work for me. I shoot a variety of guns, just about anything you can think of I shoot with while wearing these and only these over my ears. They work for everything from small pistols and my 357 all the way to my 50 cal. I will never ever wear anything else. I never have any pain in my ears after wearing them and sometimes that can be for up to 4 hours. I am a firefighter and I also bring these to work so I can block out the snoring of my fellow brothers and sisters by taking out the canal cap and I can still hear the tones drop for a call.

My ears are a tad on the small side and I always have trouble finding ear buds that are small enough to fit. If it helps you any the Apple ear buds that come with iPods are too big and don't stay in my ears. The small size of the EP4 Sonic Defenders Plus fit like a dream.

Buy these!

Great Product

I wore these while working an IDPA Championship with out a problem. Was able to hear competitors along with protection,Even held up to Magnum loads under cover. I like that you can adjust with attached plug. Will defiantly purchase again.

I very sensitive to noise and at the same time I cant't use earplugs that are hard because they hurt my ears, These surefire earplugs are very comfortable and reduce all the noise I'm concerned about.
Good purchase...

Great Hearing Protection for Helmet users

My wife and I have been using these for several years while riding motorcycles. The earplugs are effective and easy to use. They stay in when putting your helmet on and off. If one does happen to come loose, the attachment cord keeps you from losing it. We both find these plugs to be our favorite. They are great. It is really nice that they come with a case to hold your plugs when not in use. Unless they have redesigned the case since we bought ours, both of us found the case hard to use and are currently using a much better designed ear plug case left over from a previous pair of earplugs from another vendor.

Owner, Common Sense Defense

The EP4 Sonic Defenders are an excellent noise reduction solution. I have used them in shooting competitions for a couple of years now. While I like to use full size ear muffs too, the EP4 Defenders are the best solution in 3 gun or warm weather as they are light and comfortable for long term used.

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.

For best fit, click on the small Sizing Chart image at left.

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.
