The Surefire EP4 Sonic Defenders Plus (brand part no. EP4BKMPRBULK) is a bulk 25-pair case of triple-flange filtered earplugs sized medium in black. Made by Surefire, each earplug carries a 24dB Noise Reduction Rating with the attached stopper plugs inserted, and the triple-flange design is built to fit larger ear canals more securely than a standard single-flange plug. They’re engineered to lower dangerous noise levels above 85dB while their low-profile shape keeps them comfortable under a hat, hearing protection muff, or helmet. This bulk case is a smart buy for ranges, instructors, or shooters who go through earplugs regularly.
