## Overview

SureFire EP4 Sonic Defenders Plus are reusable, triple-flanged earplugs offering a 24dB Noise Reduction Rating with patented EarLock retention rings for a secure, comfortable fit.

## 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.

Review: shuts out noise and the little extra blockers let in the right amount of conversation. - these do better than any other earplug that i have tried to date. excellent product
Review: Cheap and effective - I bought the EP4s specifically for attending EDM shows. I think they work great. I was hesitant at first since this brand seems to cater more toward gun owners rather than live music attendees. But I picked the EP4 in the end due to its low profile and apparent secure fit compared to other styles of dynamic ear plugs. I've been attending a lot of live EDM shows over the past few years and I've started to notice some mild tinnitus so I wanted to start playing it more safe. I had a pair of Hearos in the past that I wore to 2 shows before one got knocked out of my ear and was lost forever. Since then I've been going in with naked ears until tonight. I just got back from a live show (Above & Beyond) where I used the EP4s for the first time, and my ears feel very good. I offered to buy my girlfriend a pair of these along with my own, but she didn't want any since she doesn't attend live shows nearly as much as I do and she doesn't have the mild ear symptoms I have. She attended the same show as me tonight without wearing anything and her ears are ringing and a bit painful whereas mine feel good considering the 3 hours of constant crushing sound we just went through. To be honest, I'm feeling some mild ringing and vibration in my ears at this time. But it's not painful, and the ringing really isn't more than what I normally have. It's very mild, I can only notice it now that I'm laying in bed in complete silence. As someone who has chronic mild tinnitus and who's left lots of concerts in the past with eardrums that felt shattered, I think the EP4s did a wonderful job. They're a bit tricky to get in since there's only one orientation in which they'll fit, but once they're in it's golden. They stayed in for 3+ hours without budging while I was jumping and dancing and all that sh*t, and neither my ear canals nor lobes felt sore afterwards. I forgot I was wearing them most of the time. I assumed the external portion of the EP4 that sits in your lobe was stiff and hard plastic, but it's actually very soft and flexible. I've thought of my ears as small and the Hearos always seemed too big for me despite getting the smaller size. I ordered the medium EP4s by following their size chart measument; the portion of my ear you're supposed to measure was exactly 1 in, so I got mediums and they fit snug, which is good. While using them tonight it was very hot and some drops of sweat rolled into my ear canals and got trapped by the plugs which was a little uncomfortable. So I took them out to dry off and while doing so heard the music at full blast: the EP4s definitely reduce the volume by a considerable amount. (Also, they were super easy to put back in with a little bit of sweat acting as lube.) Maybe the venue I was at tonight didn't have the best acoustics, but with the plugs out temporarily I heard lots more of the jarring/cracking bass tones like when you blow a speaker. Those sounds were pretty much non existent with the EP4s in. But I still felt I heard the music without distortion: clear vocals, solid bass, crisp melodies. All just quieter than had my ears been naked. But not so quiet that I felt I was losing out on the experience. Plus, the EP4s are like 33-50% cheaper than the other dynamic plugs marketed for live music. So I'm solidly satisfied with my purchase and will be using these plugs a lot during this Summer's festival season.

### ⭐⭐⭐⭐ Saves my hearing at work.
*by J***E on June 15, 2013*

Working at a club I am immersed in loud music and shouting people, which is bad day after day for my hearing. Before I would come home with ringing in my ears, now I am happy to say that I do not have that annoyance after work. This ear protection allows me to block out the loud base of our sound system while allowing me to still be able to clearly hear people talking. I am able to hear from clients and coworkers easily. Occasionally I need to hear how a speaker is tuned or to listen to how a motor is doing and need to take the hearing protection out of my ears. The design of this model allows me to easily place them back in my ears and this is why I recommend these over the foam ear plugs also made by Surefire. If you do not need to take your ear protection off then I would recommend the foam earplugs. They hide fairly well too. Clients and coworkers alike are shocked when I take them out of my ears at the end of work. The ear protection is also very comfortable. On top of that they have lasted me I do wish that the stoppers were easier to use. They are difficult for me to apply with out taking the ear protectors out of my ears. Also they are hard plastic and would occasionally become irritating when not inserted and freely moving around. I have removed them, which is a simple and non damaging process, and stored them for if I ever need them. Over all I am very happy with this product and would rate it higher if the additional stoppers were easier to apply. If you like your hearing pick up a pair of these or the foam version. They're both fairly cheap compared to trying to sleep with tinnitus.
