Thanks to proprietary TriPort headset technology, this unique combination of benefits is available in one lightweight headset. The redesigned control module and greater usability make the #1 headset choice of many pilots and military personnel even better.

Bose technology makes the difference
Most active noise reduction headsets require large earcups and considerable headband force to muffle aircraft noise. Through 25 years of research Bose has developed a better solution-TriPort headset technology. This patented innovation enables a smaller, more comfortable headset that delivers full-spectrum noise reduction.

Acoustic Noise Cancelling headset technology contributes to this high level of noise reduction. It monitors sound at the ear, identifies unwanted noise and creates an out-of-phase signal to reduce it. Our active equalization circuitry also delivers clean, full sound that improves the intelligibility of radio and intercom audio. In fact, U.S. Air Force tests with Bose headsets achieved intelligibility scores of 95% at 115db compared to 80% for conventional headsets.

At Bose, a comfortable fit is mission critical
Whether you're a general aviator or helicopter pilot, comfort counts. That's why Bose designed the Headset X with 50% less clamping force than most active noise reduction headsets. The solid magnesium headband is extremely lightweight yet durable. The sheepskin cushion eliminates hot spots, and soft, padded ear cushions provide an effective seal-even over glasses. The result is superior noise reduction in a comfortable headset that weighs only 12 ounces.

Focus on your flight, not your headset controls
The redesigned control module is 30% smaller than the previous version and even easier to use. Its slim design puts all functions-including dual thumbwheel volume controls-within easy reach. And improved boom microphone design enables smoother, more precise adjustments.

Features:

• TriPort Headset Technology: Utilizes three small ports in the
  earcups to produce a rich audio performance. Enjoy clearer
  communications.
• Acoustic Noise Cancelling Headset Technology: Electronically
  identifies and reduces unwanted noise, allowing improved
  intelligibility of radio and intercom audio. Noisy distractions
  are reduced, so your concentration is improved.
• AdaptiSense Headset Technology: Sophisticated electronics
  monitor current demand and instantaneously adjust the
  voltage to maintain maximum performance. Smart shutoff
  detects when you've stopped using the headset for even
  greater battery life-up to 40 hours from just 2 AA batteries.
• Battery Life Status Indicator: LED that reflects three status
  indications for remaining battery power.
• Active Equalization:
  Electronically tunes the frequency response, enabling
  outstanding audio performance for improved speech
  intelligibility.
• Magnesium Alloy Headband: Provides exceptionally strong,
  durable frame that's remarkably lightweight and comfortable.
• Center Torsion Spring: Enjoy a consistent, comfortable fit for
  any size head with half the clamping force of conventional
  active headsets.
• Adjustable Headband Sliders: Up to 3 inches of adjustment in
  headband length.
• Sheepskin Headband Cushion: Soft headband cushion
  eliminates hot spots and provides comfortable, even
  distribution of the headset weight.
• Earcup Rotation: Earcups rotate 10 degrees vertically and
  horizontally to maintain uniform pressure around the ears for
  superb passive noise reduction performance and comfort.
• Boom Microphone: Smoother, more precise adjustment so you
  can put the microphone right where you want it-and keep it
  there.
• Weight: 12 oz (340 g).
• 5-year Transferable Limited Warranty: Coverage for parts, labor
  and second-day return shipping expenses for any non-abuse
  and acts of nature malfunction.
• Carry Bag: Provides an easy way to bring your headset wherever
  you go.
• Integrated System Design: Ensures the highest levels of
  performance from a system that is designed so every element
  (speakers and electronics) works in harmony with every other
  element.
