The Airman 850 is approved for aircraft use under FAA TSO C57a and C58a.
Sound Quality:
At just 4 oz., the Airman 850 is the lightest ANR product in the
marketplace. Wind noise and ambient noise is reduced by up to 12
decibels (dB) of. The headset also features a noise-cancelling electret
microphone.
Comfort and FitAn 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.
MicrophoneThe 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.
ControlsThe Airman 850 contains an On/Off switch to control ANR power and a Hi/Low switch for controlling receiver volume.
Cordage and PlugsThe 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.
