Surefire EP4 Sonic Defenders Plus are an ideal choice for those who need reliable protection without compromising sound quality. The black finish provides a sleek, clean look that's both professional and understated.
The patented triple-flange design is comfortable to wear for extended periods of time and allows for a secure fit that won't fall out. The EP4's advanced acoustic filters provide superior sound clarity and still allow for a level of hearing that is safe and comfortable.
Thanks to the low-profile design, they can be worn discreetly under hats or other headgear, making them ideal for any environment. With Surefire EP4 Sonic Defenders Plus, you can trust that you're receiving high-quality ear protection without sacrificing any sound quality.
Your hearing health should never be ignored. SureFire EP4 Sonic Defenders Plus will protect your hearing against Noise-Induced Hearing Loss (NIHL) without compromising your ability to hear routine sounds or conversations in noisy environments.
Their triple-flanged-stem provides a Noise Reduction Rating (NRR) of 24 dB. Safe sound levels are allowed to pass through into the ear canal, while potentially harmful noises (above 85 dB) are reduced via our proprietary noise-reducing filter.
EP4s include attached filter caps that can be inserted for additional protection, blocking out lower-level noise, like that heard on an airplane, where hearing ambient sounds or conversations isn't critical. Sonic Defenders are made from a soft, durable, hypoallergenic polymer that provides all-day comfort and extends product life (up to 6+ months, depending on usage and care).
