SureFire EP4 Sonic Defenders Plus – Smart Hearing Protection That Keeps You Aware

Block Harmful Noise, Hear What Matters

The SureFire EP4 Sonic Defenders Plus solve a common issue for people in loud environments: how to protect your ears without losing the ability to hear important sounds. These earplugs feature a Noise Reduction Rating (NRR) of 24 dB, thanks to a patented triple-flanged stem and noise-reducing filter. They allow safe sound levels to pass through, while reducing dangerous noises above 85 dB. When full quiet is needed — like on a plane — simply insert the attached filter caps to block out lower-level background noise completely.

Built for everyday use, the EP4s are made from a soft, durable, hypoallergenic polymer that ensures all-day comfort. The EarLock® retention rings keep the plugs stable using seven contact points, so they fit securely and consistently, no matter your activity. Whether you're at work, on the range, or in the field, these earplugs stay in place and feel good all day.

Designed for Use With Gear and Communication Systems

The EP4’s low-profile design makes them easy to wear with helmets, hats, masks, or even headphones. They can also serve as earpieces for compatible radio communication systems, including models from Thales, Motorola, Silynx, Peltor, and more. This makes them ideal for tactical professionals, security teams, and industrial workers who need clear communication in noisy settings.

The EP4s are available in black, clear, or orange, and come in small, medium, or large sizes to match your ear’s concha bowl. Each set includes a carry case and a polymer lanyard to keep them together and clean. You can purchase them in single-pair packs or packs of 25 pairs, and they are made in the U.S.A. for lasting performance — up to 6+ months, depending on care and usage.
