Tactical headphones with active noise reduction Peltor range guard (RG-OTH-4) is a new version of electronic headphones for hearing protection, which replaced the Peltor Tactical 6S model. And yes, finally this model has a standard 3.5mm audio input and better electronic components. It’s also now much easier to replace batteries. And, of course, a new design! All this together makes this product truly unique. The Peltor ™ Sport RangeGuard ™ electronic hearing protection headphones suppress gunshots for hearing protection while amplifying your voice for clear communication. The noise reduction level (NRR) is 21 decibels. The low-profile design of the cups makes it comfortable to work with shotguns, rifles and shotguns. Single, external cover of the battery compartment. Adjustable soft headband. Robust built-in microphones.
