Product 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.

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.
1. They come with a tether.
2. They come with a case
3. They are easy to use
I was skeptical at first, but after getting a set, I am pretty surprised the DOD in its infinite wisdom did not get these? They fit the ear pretty well, I got a set for myself and my daughter and by far they held up. I was shooting skeet and I found my ability to hear commands and speak were not hindered and my hearing was preserved. Mind you, I did this without closing the sound plugs. For the price you cannot go wrong.
Buy a pair, throw them in your range bag as a back up for the back up. Sometimes ear muffs do not cut it with certain buttstocks (I learned that lesson with my G3 pattern rifle the PTR-91 and some of AR-15s). Sometimes low profile earplugs like this are so well molded to your ears you do not realize they are in till you look at a loved one you can hardly hear them.
If I'm in an environment that is too loud, my ears buzz like a blown out speaker and physically hurt - so I couldn't go to any concerts or big sporting events. Even dance clubs and bars were risky.
I also cannot stand earbuds, they are physically painful to me immediately upon putting them in my ears. I can only use on ear headphones even for hands free (yes I look ridiculous). So when I talk about comfort, I'm speaking from that perspective.
I'm evaluating these earplugs based on using them at concerts/music festivals, where I still want to be able to hear.
Loop Experience Pro Earplugs
$40
Best sound, sounds the most like someone just turned down the volume rather than muffling it, but still muted enough for my super sensitive ears. My ears cannot tolerate earbud headphones, so the fact I can tolerate these at all is a testament to how comfortable they are. But with my sensitive ears I've found I can't quite wear these for a full concert - so I save these for the bands/songs I care about hearing the most clearly. I use the SureFire for everything else. But if you ears are ok with any type of Earbuds headphones, I'd recommend just these alone.
SureFire EP4 Sonic Defenders
$15
Best comfort, but some of the higher tones get lost (as happed with all of the other ear plugs too other than loop). Has a cap for the earplugs tube you can have open or shut to allow more or less sound. I tend to use these with the cap closed for most concerts until the band I came for starts playing, then I switch to the Loop for the better audio quality. If for some reason I was forced to choose to only use one set of earplugs, I would choose these. But also my ears are SUPER sensitive about anything being in them even in the slightest, it causes me physical pain. If you can tolerate any type of earbud headphones, I'd recommend the Loop Experience Pro Earplugs instead. But if you're on a budget, or you have super sensitive ears like me, these are Amazing!
Eargasm High Fidelity Earplugs
$50
Didn't work for me, I couldn't get them in a proper position to seal and Stay sealed. They kept loosening and popping out (not enough to lose them but enough to lose all of the noise reducing effect). I don't use these at all.
EARasers Noise Cancelling Earplugs
$45
Most low profile, worked ok but not great, less comfortable than SureFire or Loop. I don't use these at all. Loop are cheaper and better.
