Designed to provide for two-way communication in high noise conditions in aircrafts, airfield services, as well as flight simulators. 

Suitable for operation at temperatures from minus 50 ºС to 50 ºС and high relative humidity to 98% at temperature of 35 ºС.

Noise-canceling headphones provide confident sound reception, and the laryngophone allows you to remove sound vibrations from the larynx and transmit them with good intelligibility to the sound tract.

The headphones are protected from contamination by individual textile covers, which are easily washed with ordinary detergents.

The laryngophones are located in a comfortable leather "collar", which is easily fixed to the neck with the help of a push-button adjustable attachment.

The connector ЖФ3.645.009 is installed
