Zekler 412RD FM-radio and Level-dependent

Used but in good condition. Comfortable earmuff with built-in FM stereo radio and level-dependent monitoring. The microphones on the front of the cups pick up ambient noise so you can hear what's going on around you and facilitates communication with your colleagues. Should the sound reach harmful levels the electronics react immediately and take down the level to max. 82 dB(A). Extremely good in environments with impulse noise, or varying levels of noise. You can choose the mix of functions (radio listening or level dependent system) that is most appropriate for the current situation. Good attenuation at medium, high and low frequencies. The headband with fork attachment and the wide sealing rings provides uniform headband pressure and comfortable use.
