Designed to provide for two-way communication 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 100% at temperature of 35 ºС.
It has improved electroacoustic and ergonomic characteristics.
The design of the headphones increases noise reduction in the frequency range (100-300) Hz by 10 dB, which reduces noise and fatigue.
There are several modifications:
- ГСШ-29Э shielded
- ГСШ-29М with one earphone
