SureFire EP4 Sonic Defenders Plus Ear Protection - Medium - Black

SureFire EP4 Sonic Defenders Plus are engineered for people who take their hearing health seriously but still need to stay alert to their surroundings. Whether you're on the range, on the job, or in a noisy environment, these patented triple‑flanged earplugs reduce harmful noise while allowing safe, routine sounds to pass through—so you stay protected and aware.

A proprietary noise‑reducing filter lowers dangerous sound levels above 85 dB, helping prevent Noise‑Induced Hearing Loss (NIHL). Insert the attached filter caps for even greater protection when ambient awareness isn’t needed, such as during air travel or high‑noise industrial settings. Made from soft, hypoallergenic polymer, EP4s deliver all‑day comfort and long service life.

With EarLock® retention rings for a secure, repeatable fit and compatibility with popular radio communication systems, these earplugs are built for professionals and everyday users who demand reliable, low‑profile hearing protection.
