The most technologically advanced Bose® headset ever. 
Preferred by pilots, year after year
Bose pioneered active noise reducing headsets nearly 20 years ago, and pilots continue to prefer the Bose Aviation Headset X today. For nine years in a row, it's been rated #1 in Professional Pilot's annual survey, claiming 2009's top honors for comfort, clarity and technical advancement.
Packed with headset innovations
A rare combination of benefits helps distinguish this headset from all other pilot headsets. Most importantly, Acoustic Noise Cancelling® headset technology, pioneered by Bose, dramatically reduces the engine roar you hear in the cockpit.
Here's how it works: Small microphones in each earcup monitor ambient sound. Innovative electronics immediately identify the unwanted noise and create an opposite signal to reduce it. The result? You hear dramatically less engine noise, and more of your communications.
This advanced noise reduction technology combines with exclusive Bose headset design and active EQ to provide you with quality audio in a compact headset weighing only 12 ounces.
Lighter is better
With lighter, more compact earcups, Aviation Headset X requires significantly less clamping force than most noise reduction headsets. Many pilots say this easy-on-the-head design makes a big difference in how they feel after a long flight
The solid magnesium headband is also extremely lightweight and durable. A sheepskin cushion eliminates hot spots, and soft ear cushions provide an effective seal, even over glasses.
Long battery life, smart controls
Proprietary AdaptiSense® headset circuitry gives you at least 40 hours of headset use from just two AA alkaline batteries. This Bose innovation automatically adjusts the headset's need for power according to the levels of cockpit noise and radio communications.
