i am looking to buy a ear plugs protection from Surefire. Which one is the good one and which can protect your hearing from firing ar and machine gun in door ? Also Might use this when i enlist into the army guard too. Surefire has a few models i don’t know which one is the best to buy…
So if you own one, please give me some idea…
Thank you
I have been using Surefire’s EP3 Sonic Defenders for the past couple of years and they work great for me both indoors and outdoors. As far as machineguns are concerned though, I have ony been able to use them in machinegun shoots on outdoor ranges so I can’t speak for indoor machinegun use. Outdoors, I have used them while firing most machineguns used in the Marine Corps with no problem. As for indoor pistol and rifle shooting they do a more than adequate job IMO, and I have no trouble hearing when somebody is talking to me, or being aware of other noises around me for the most part. Here’s a link to the their official page in case you have not already seen it. They explain the technology quite well there:
i don’t even know what size i am. i guess i will start with small i will go with ep4. I will see… thank you sir.
I think the EP3 medium are designed to fit the average person.
Stan is right. The Mediums are for average sized ear canals. As Smalls are for smaller than average ear canals and Larges are for larger than average ear canals. When I got my first pair I was paranoid that I might need the Large ones but I got the medium ones instead to try them out and they fit perfectly. Unless you know for a fact that you have small ear canals I think you would be better off getting the medium ones. However that’s just my opinion.
You could always just measure your Helix Bowl…
i don’t know. i think i might order small because i am not a big tall guy i am 5’6 :laugh:… I will check surefire for size chart. 
Order the mediums. They will work.
Go with the EP4’s (as they offer the most protection).

I use my EP3s indoors while shooting my HK45. And whatever anyone else shoots. I bought Mediums.

i am making my mind i am going for Ep3 medium.
Honestly, this has very little to do with your stature, and everything to do with the dimensions of your ears – and the correlation is by no means exact. Iknow very large men who use small earplugs, and I tend to use the large size, despite the fact that I am by no means a big dude.
Definitely start with mediums. I’m not 100% certain, but get the sense that the size differences are really less about the ear canal itself, and more about the bowl portion of the outer ear, since this is what the balance of the plug will conform to for best fit.

I have been using the EP3 mediums for about a year now and have been very pleased with them. They are very comfortable and the noise reduction is enough but not too much. It takes the edge off but I can still hear what I need to hear. However, indoors there have been times I will put muffs on as well depending on what I (or others) am shooting. Outdoors, no problems.
I have been using the EP3 mediums and they work well for me both outdoors and indoors. Most of the time if indoors I will aslso use muffs with them.
This. There are instructions on Surefire’s website.
I’ve used my EP4s indoors, outdoors, and under overhead baffles with a variety of guns. They provide protection, but I prefer my standard headsets.
I meant that size was dependant on the size of your ear’s helix bowl. I’m not sure why I said ear canal. I must have had a brain fart:confused:. I apologize for that.
I have, and used, both the EP-3 and EP-4.
The EP-4 have a higher dB rating but my ears ring a little when using them with 223 outdoors (they ring more with the EP-3)
Both inserted properly with plugs fastened.
I’ve ended up going back to my 33dB Flents.
I have the EP3 and EP4, both in medium.
For me the extra baffle on the EP4 prevents adequate insertion into my ear canal so I use the EP3. I also removed the plug as I found I didn’t need it. I should add that I don’t shoot my AR indoors.
