Using the latest in ANR circuitry to target and reduce wind noise in jet cockpits, the Airman 850 provides up to 12 decibels (dB) of noise attenuation between 100 and 2000 Hz. At just four ounces, the headset is the lightest ANR product in the marketplace, and ear cups and cushions have been enlarged from previous models to enhance pilot comfort. Additional features include a set and forget volume control feature, noise-canceling electret microphone and fully flexible boom. The Airman 850 dramatically improves the clarity of communication and does not require batteries or panel power—active noise reduction is powered by microphone bias. Telex Airman 750 and 850 headsets are used in more than 70 percent of commercial airframes. The Airman 850 is available for Boeing, Airbus and other airframes and does not require specialized intercom adapters.
As a 737NG-600,700,800 and Max series Captain, I love the comfort level of this headset. No batteries to buy and replace, easy to slip off and on when dealing with flight attendants, and easy on my head while wearing glasses.
Ive been using the Telex 850 for about 15 years on the Boeing 757/767/777. It provides much better noise attenuation than the new David Clark Pro X, that cost $300 more. Im able to hear others speak in the cockpit clearly, while cancelling out the background noise. Its comfortable wearing for long periods, but my ears start hurting occasionally on long haul flights (15-16 hours). Much better (quieter) than the D/C Pro X for much less.
This headset has standard dual plugs on the end of the cord. One is for microphone and the other is for the headphone. Most Boeing jets are equipped with standard dual plug jacks, however some are modified for different plug types so you must confirm your own application as we cannot say for sure that it will work in all Boeing 777.
No, these headsets do not have Bluetooth. Yes, they are Dual GA Plug headsets.
The carrying case is included with the purchase of the Telex Airman 850 headset.
