SureFire EP4 Sonic Defenders Plus filtered Earplugs, triple flanged design, reusable, Black, Medium

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.

I have a problem finding earplugs that fit right but still protect from noise. Most earplugs will give me headaches after 30 minutes or so, but these don’t. They fit nicely under helmets and don’t come out when you take a helmet on and off. You also can adjust the amount of sound that is blocked. It’s good to be able to hear vehicles around you on a motorcycle, so blocking some but not all noise is important.These lasted me about 6 months before the plastic lost its softness. I like them enough that I’ll me getting another pair.

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.
