SureFire EP4 BK-MPR-BULK (25PK) Sonic Defenders Plus Filtered Flanged Earplugs - 24dbB Noise Reduction Rating - Medium - Black - Box of 25

EP3s are available in small (S), medium (M), and large (L). Proper size is based on the dimensions of your ear's concha bowl. Size "medium" fits most people; however, to ensure the best possible fit, click on the Sizing Chart thumbnail image above or download detailed specifications here to also view the sizing chart on page 4. For those with larger (in diameter) ear canals, the three-flange stem of our EP4 Sonic Defenders may provide a better fit than the EP3's two-flange stem. EP3 Sonic Defenders are sold as a single left/right set or in a box containing 25 sets. Each set is packaged in a convenient carry case and includes a polymer lanyard. * RADIO COMM SYSTEM COMPATIBILITY: 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 [NSN: 6515-01-549-6448, 6515-01-549-6453, 6515-01-549-6457]
