SureFire EP4 Sonic Defenders Plus - Black - Medium - 1 Pair
The SureFire EP4 Sonic Defenders protect your hearing without interfering with your ability to hear routine sounds or conversations. The triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating of 24.
Safe sound levels can pass through into the ear canal, while harmful noises (above 85 dB) 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 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.

So far all I was able to do was try them on and they are comfortable. Haven't tested them yet at the range, the reason for the average rating.

Sure fire sonic defenders ear plugs
by Josh Freeman
These ear plugs are great for what I do. I use them for work and when I'm out at the gun range. Thanks primary arms for the email!!!
These work great and fit comfortably
These work very well, fit well, and the price is right, but even after a month of general use around the farm I still have a hard time getting them in my ears! I would actually give them 4.5 stars.
Won't stay in the ear
by John Webb
They appear to be the correct size but will not stay in my ears. They slowly push themselves out after a few minutes. Tried to insert without optional plug in and didn't change the result.
They cancel noise a little too good for normal conversations to take place. will try the EP3 next time.
They work great.
