ATTN PREPPERS AND MILITIA FOLKS: These things are great! I went to Max Velocity Tactical training in West Virginia and I had the standard workplace-style earplugs in during a live fire drill with multiple people on range shooting in a coordinated effort. It was cold and I was wearing a balaclava to keep my head/face warm (February in WV) and while I was shooting at a reactive target (aka, suppressing the enemy) my left earplug fell out while I was kneeling beside a tree (to my left). The sound of gunfire erupting all around me as well as from my own rifle reverberating off of the tree gave me a ruptured eardrum. I wasn't able to just stop and remove my gloves and balaclava to readjust my earplugs, I mean, I could have but I didn't want to be that guy...this is some serious training. Anyhow, I noticed that Max (the trainer) was wearing these and I liked how they fit better into the ear canal. Now that I am using them, I find them to be comfortable and quite effective. The best part is that the white or red plug in the middle (as seen in the pic) can be removed to accommodate for your comms. For instance, if you run a throat mic, the sound tube can fit right in there (as it was engineered for) and you don't have to sacrifice hearing protection while using your comms. Buy these or save a lot of money and get some Peltors. My wallet likes EarPro better.

Until now, I've been using those foam ear plugs to shut out the sound while sleeping on long plane rides and when using power tools. I also used conventional ear-muffs on construction sites and weekends at the shooting range. I first saw the SureFire EarPro's on Magpul's handgun videos and thought, what's so different about these. After looking into them on SureFire's website, and finding out they weren't so expensive, I decided to give them a try. Before buying them, I put a ruler against my ear and took a picture of myself in the mirror. According to SureFire's fitting chart, I was a small. After receiving the EarPro's from the merchant, I tried them out for sleeping and on the range. They are comfortable in the ear for extended use... until you roll over on your ear on the pillow. Not recommended for sleeping in a real bed... maybe on the plane where you cannot rollover? On the range, they suppress sound well in "open" mode and I could still have a conversation with the range master. It was all good until high pressure ammo arrived. I shoot mostly 9mm, so I can still use the EarPro with the plug undone. But when .40 and .357 shooters started firing in the adjacent lanes, I had to close the plugs for the full NRR 24 effect. One thing to consider; the NRR 24 was probably measured at the tip of the plug, but human hearing is not only down the ear canal. A set of ear-muffs completely covering the outer ear and pressing against the side of the head would probably have better noise reduction capabilities even at the same NRR rating. I'd say, the EarPro would be enough on an open outdoor range, but indoors or under a roof, the echo from high pressure ammunition will shake your whole skull - not just your ear. I think the best solution would be wearing the EarPro "open" under electronic ear-muffs. Then you have great noise reduction but still can hear dialogue.

After years of abuse, my original set of EP3s cried to be replaced (they still worked OK but the silicone had become stiffer and wouldn't stay in my ears consistently). These new EP3 are super comfortable and stay in place much better than the old ones I had. The silicone flanges are twice the size compared to the original ones and seal out noise very well. I use these when I travel overseas (to doze off during 14-16 hour flights), at the office when I want to focus and I have an additional pair that I keep attached to my USAR helmet. We use all sorts of loud power tools for collapsed structures, trench work and other activities, and having small and comfortable earplugs is great, and I don't get hot and sweaty as I did when using regular earmuffs with my helmet. I'll keep buying EP3s as long as SureFire offers them!(BTW, I also have some EP7s but I find them too bulky and uncomfortable in comparison to the EP3s.)

I have what I would like to call the normal ear size, my husband's ears are a little bigger, my kids ears are a little smaller. The EP3 is very large feeling in my ear, we sent these back and went with the EP4 size medium and it's much more comfortable. The EP4 works very well, drowns out a lot background noise so that you can focus on a conversation It was something that worked very well for me when I was having a chronic lyme flare up and having extreme sound sensitivity. I carry these on my keychain now. My husband takes a pare of the EP4s with him when he goes away.on business to drown out the noises at night as well as other people snoring. LOVE THEM, just didn't love the EP3's.

Surefire EarPros are up to the standard that all Surefire products are expected to meet.I use these for target shooting indoors and outdoors. They are so comfortable and easy to put in the ear. They work very well with doubling up hearing protection with a full coverage earmuff because they do not protrude from the ear.It would have been nice if they came with a little pouch or something to keep them in but the plastic clam-shell holder that they are packaged in works fine. When I purchased them, I had to no idea what color they were. These ones are clear if it is not apparent to you from the picture.I have not used them without the plunger inserted. When shooting I am usually not talking to people so I don't really care about any ambient sound.Overall, this is a great hearing protection option at a very reasonable price.

Takes a bit of practice to get a good seal, but after you get the hang of it, it blocks out a lot of sound when filter caps are in. With filter caps out, it still blocks out some noise, however it doesn't muffle the sound quality of whatever you are hearing, be it spoken voice or a band at a concert. For maximum isolation and noise reduction from ambient sounds however, use them with filter plugs in.They are flush enough that they aren't noticeable when on your ears. However, with filter caps out, they stick out a little bit.I love how you can change from filter caps in/out whilst still on your ear, allowing for great versatility.Not sure how long they will last, but I plan on taking good care of them. Surefire states that they can last up to 6 months, however some people have said that they have been using theirs for 2 years with good care without any issues. Genuinely impressed with this product. Highly Recommended.Pros:Effective at Blocking soundComfortableReusableDiscreet and Low-ProfileVersatile useCons:Takes a bit of practice getting it in properlyNot sure how long it will last, requires regular cleaning

Amazing product for work, I use it as an ear insert for my clear tube earpiece and it is fantastic! The audio quality is amazing and it stays in place in my ear perfectly throughout the day. I would highly recommend, especially for the price.

I use these to sight in my .308, they work great and are tiny. I dont like big bulky earmuff style hearing protection.

Excellent ear plugs for shooting muzzle loading black powder for reenactments. Because they are clear you hardly see them so fine to wear when safety is important but looking authentic is also a key aim. They are comfortable and with the plugs open you can still hear enough but stay safe. I'm very impressed with these. The little case is also handy to keep them about when needed.
