ANR Without Batteries
The Airman 850 takes our most popular
lightweight headset to the next level.
It’s the only lightweight ANR headset that
doesn’t require batteries. The ANR feature
is powered entirely by microphone bias.
The Airman 850 provides 12 dB of active
noise reduction and is specifically designed
to reduce wind noise in jet cockpits — to
protect hearing and significantly reduce
fatigue. It also includes a “set and forget”
volume control and folds easily into the
included carrying case.
