NRA ZEM Hearing Protection

Description A breakthrough in hearing protection, ZEM lets you hear what you need to hear but protects you from what you don’t. ZEM technology is the product of years of research and development by a renowned authority in auditory research-Dr. Jozef Zwislocki, distinguished Professor Emeritus at Syracuse University. The ZEM takes advantage of the mechanical energy of the sound wave to filter, reflect, and cancel them before they reach the ear. This remarkable technology filters out harmful, high-decibel noises, but still allows low-frequency sounds, such as talking to be heard easily. The ZEM is compact and folds up for easy storage, lightweight (only 1.7oz) for greater comfort, and gives you a noise reduction rating of 26dB. Includes four replacement ear cuffs. Now available in black, red, blue and green.
