The SureFire EP4 Sonic Defender Plus delivers professional-grade hearing protection against Noise-Induced Hearing Loss (NIHL) without sacrificing your ability to hear everyday sounds or conversations in noisy environments. Featuring a triple-flanged stem design and a proprietary noise-reducing filter, these earplugs deliver a 24-dB Noise Reduction Rating (NRR), allowing safe sound levels to pass into the ear canal while reducing potentially damaging noises above 85 dB to safer levels. Attached filter caps can be inserted for additional protection, ideal for environments like aircraft cabins where ambient hearing is not essential. Built from soft, durable, hypoallergenic, medical-grade polymer, the EP4s offer all-day comfort and long-lasting durability of up to six months or more, depending on use and care. The patented EarLock retention rings utilize seven contact points to lock the earpieces securely in place with a consistent, reliable fit every time. Their low-profile design makes them compatible with masks, helmets, hats, headphones, and supplemental hearing muffs. The EP4s also serve as earpieces for compatible radio communication systems. Each set comes packaged in a convenient carry case and includes a polymer lanyard.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e24-dB Noise Reduction Rating (NRR):\u003c\/strong\u003e Proprietary noise-reducing filter lowers dangerous sound levels above 85 dB while allowing speech-level conversations to be heard clearly.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePatented EarLock Retention Rings:\u003c\/strong\u003e Seven contact points lock earpieces comfortably and securely in place, providing a consistent fit every single time.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachable Filter Caps:\u003c\/strong\u003e Included caps can be inserted for full ambient noise blocking, ideal for travel or high-noise environments where situational awareness is not required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHypoallergenic Medical-Grade Polymer:\u003c\/strong\u003e Soft, durable, and long-lasting construction provides all-day comfort and an extended product lifespan of 6+ months.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow-Profile, Multi-Compatible Design:\u003c\/strong\u003e Fits comfortably under helmets, hats, and masks, and is compatible with select radio communication systems including Motorola, Thales, Harris, and Peltor platforms.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Surefire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e EP4-OR-MPR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 084871318884\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Orange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNoise Reduction Rating (NRR):\u003c\/strong\u003e 24 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSNR (Closed, EN 352-2:2020):\u003c\/strong\u003e 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSNR (Open, EN 352-2:2020):\u003c\/strong\u003e 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Style:\u003c\/strong\u003e Triple-Flanged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type:\u003c\/strong\u003e Proprietary Noise-Reducing Filter with Attachable Filter Caps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetention System:\u003c\/strong\u003e Patented EarLock Retention Rings (7 contact points)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Hypoallergenic, Medical-Grade Polymer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 1 Pair, Carry Case, Polymer Lanyard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRadio Comm Compatibility:\u003c\/strong\u003e Thales Covert Security Harness; Harris Security Force Communication Set; Motorola Surveillance Kits; Tactical Command Industries Tactical Earpiece Products; Peltor Lightweight Systems-Hearplug; Silynx C4Ops Headset\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
