Comfort and Fit
An adjustable headband gives the wearer two inches of up and down earphone adjustment per side, while gimbal mounting improves the headset’s side-to-side comfort. The ear cups and cushions have been enlarged from previous models to enhance pilot comfort.
The Airman 850 features a miniature, amplified, noise-cancelling electret microphone that provides superior 400Hz hum rejection. The flexible boom rotates 320° and can be worn on either side of the head. A replaceable windscreen is included to minimize popping, hissing, and breathing sounds when speaking.
The Airman 850 contains an On/Off switch to control ANR power and a Hi/Low switch for controlling receiver volume.
Cordage and Plugs
The microphone cordage is protected inside the boom. A strain relief on the cord provides maximum durability. Shielded wire throughout the headset protects against RFI and EMI.
