XPR7000 RMN4052B Tactical Headset with Boom Microphone
RMN4052B Tactical Headset with Boom Microphone
Ideal for two-way communication in extremely noisy environments, this medium-weight headset features a dual-muff, tactical-headband style and includes two microphones on the outside of the earcups. With a noise reduction rating of 25 dB, the headset suppresses harmful sounds to safe levels and amplifies low sounds up to five times their original level, but never more than 82 dB. This tactical, medium-weight headset will keep you connected and comfortable in even the noisiest environment.
