SureFire EP4 Sonic Defenders Plus Hearing Protection

The SureFire EP4 Sonic Defenders Plus are designed to protect your hearing from Noise-Induced Hearing Loss (NIHL) while allowing you to hear routine sounds and conversations in noisy environments. With a Noise Reduction Rating (NRR) of 24 dB, their triple-flanged-stem effectively reduces harmful noises above 85 dB using a proprietary noise-reducing filter. These earplugs feature attached filter caps for additional noise blocking, ideal for environments like airplanes where ambient sounds aren't crucial. Crafted from a soft, durable, hypoallergenic polymer, the EP4s offer all-day comfort and extended product life, lasting up to 6+ months with proper use and care.
