Surefire Sonic Defenders: Noise Filter Blocks Loud Sounds To Help Prevent Hearing Damage

In-the-ear plugs help prevent hearing damage by blocking potentially dangerous noise from entering the ear canal. Internal Hocks Noise Braker® blocks sounds above 80dB, but allows attenuated sounds below that level to pass, so your ability to hear conversation is not adversely affected. Made from a soft, comfortable, hypoallergenic medical-grade polymer that’s ergonomically shaped for a tight seal and secure fit that won’t work loose. Where extra sound isolation is desired, insert attached stopper plugs to block low-level sounds as well. Available in standard EP3 model (16dB NRR) and EP4 Plus with enhanced noise reduction (19dB NRR). EP5 model (26 dB NRR) includes a lanyard and does not have noise block. Suitable for situations with constant noise or when the ability to hear ambient sounds is not a necessity.
