Surefire EP4-MPR-BULK EP4 Sonic DefendersPlus

The Surefire EP4-MPR-BULK: Sonic Defender Plus is designed with your auditory health in mind. It acts as a guard against Noise-Induced Hearing Loss (NIHL), ensuring that you can easily hear daily sounds and interactions, even in noisy settings. The triple-flanged-stem design offers a Noise Reduction Rating (NRR) of 24 dB.

While safe sounds are allowed to pass into your ear canal, harmful noises exceeding 85 dB are minimized through our unique noise-reducing filter. The EP4s come with integrated filter caps that can be utilized for extra protection, enabling you to block out low-level noise like the kind experienced on airplanes, making them ideal for situations where listening to background sounds or conversations is not necessary.

The Sonic Defenders are manufactured from a soft, durable, hypoallergenic polymer. Not only does this ensure comfort throughout the day, but it also prolongs the product's lifespan, lasting up to 6+ months depending on usage and maintenance.
