Headset-Microphones H-161/U and H-161A/U provide facilities for transmission and reception of voice-frequency speech signals. They can be used with portable and vehicular radio sets in areas where background noise is medium to high. They can be worn under the M1 infantry helmet. Both models are similar, except that the H-161A/U eliminates more background noise.
