Sennheiser HME 25-1 003374 Folheto

Cat No. 003374

General Description

The HME 25-1 headset features dynamic, closed headphones and a broad-
cast quality MKE 2 Red Dot omni-directional close-talk microphone. It has 
been designed specifically for use in noisy environments. Background 
noise attenuation is achieved by the extreme closeness of the micro-
phone to the mouth. In addition, omni-directional microphones do not 
suffer from increased low frequencies (proximity effect) and so give a 
natural sound at close talking distances.
