EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flange stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 19dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are greatly reduced via a proprietary design that incorporates the patented Hocks Noise Braker® filter. EP4s include attached stopper plugs, which can be inserted to block out lower-level noise like that heard on a plane, or in situations where hearing ambient sound or conversations isn't critical, such as when trying to sleep. The right/left color-coded Sonic Defenders Plus are made from a soft but durable, hypoallergenic polymer and are ergonomically shaped, with an adjustable-stem design, providing a secure fit, all-day comfort, and extended product life (3 to 6+ months, depending on usage and care). And their low-profile design means they can be worn while wearing a helmet or mask or while using a phone or headset.

EP4 Sonic Defenders Plus are sold in single left/right sets in a box containing 25 sets in small, medium, and large. Each set is packaged in a convenient carry case. Medium EP4 Sonic Defenders Plus fit most people with larger ear canals comfortably. Sizing is based on the size of the ear's Helix Bowl. Consult Sizing Chart for proper fit.

For those who do not have larger ear canals, double-flanged EP3 Sonic Defenders may provide a better fit.

Please Note: We cannot ship Surefire products outside the United States.
