Surefire Ep4 Sonic Defenders Plus Medium Clear 25 Pair

The Surefire EP4 Sonic Defenders Plus in medium clear is a reusable hearing protection system designed to let you stay aware of your environment while guarding against loud impulse noise at the range. Unlike foam earplugs that muffle everything, these electronic earplugs use a patented noise-reduction filter to pass safe ambient sound and conversation through to your ear canal while clamping down on potentially harmful noise above 85 dB—like gunfire and muzzle blasts. They're engineered for shooters, hunters, and range workers who need to hear range commands, spotters, or their own shooting buddies without sacrificing hearing safety.

Comfort matters when you're wearing protection for hours. The EP4 uses a soft, hypoallergenic polymer construction with a triple-flanged-stem design that seals securely and stays put thanks to Surefire's EarLock retention rings, which lock the earpieces in place with seven contact points. That means no constant readjustment between shots. The material is durable enough to last six months or longer with proper care, making a 25-pair bulk pack a sensible investment for frequent shooters, hunting camps, or training facilities.

Each pair includes attached filter caps you can insert for even more protection when ambient sound isn't necessary—useful on flights, in extremely loud industrial settings, or during the loudest suppressed or unsuppressed rifle shoots. With filter caps inserted, you get a 24 dB Noise Reduction Rating. The reusable design and bulk quantity make this pack economical compared to constantly replacing single-use foam plugs, and the clear color is unobtrusive at the range.

Frequently Asked Questions

Can I hear range commands and conversations while wearing EP4 Sonic Defenders?

Yes. The EP4 is designed to let safe ambient sounds and conversations pass through to your ear canal while reducing noise above 85 dB. This makes them ideal for shooting environments where communication is important, unlike passive foam plugs that block out everything.

What do the filter caps do?

The filter caps insert into the earplugs to provide additional noise reduction for situations where hearing ambient sound is not necessary. With filter caps inserted, the earpieces achieve a 24 dB Noise Reduction Rating. They're useful on flights, in industrial settings, or during the highest-decibel shooting scenarios.

How long do these earplugs last?

Each pair is reusable and can last six months or longer depending on how often you use them and how well you care for them. With proper maintenance, a 25-pair pack provides extended value compared to single-use foam alternatives.

Will the EP4 stay in place during shooting?

Yes. The EarLock retention rings use seven contact points to lock the earpieces securely in place and fit the same way every time. The triple-flanged stem design provides a reliable seal and all-day comfort without constant readjustment.
