is a previous model variant of the Bose Aviation Headset X, a professional-grade pilot headset known for introducing advanced active noise reduction (ANR) technology. While it has been succeeded by newer models like the , it remains a popular legacy choice in the aviation community.
It has new earpad cushions, a large aftermarket head pad cushion already installed and some smaller head pads and three new microphone
wind screens. This headset has the U-174 Helicopter plug but there adapter cables on eBay and other sites that make it a dual plug or single

Bose Aviation Headset X
, a landmark active noise reduction (ANR) headset While it has been succeeded by the A20 and current A30 models, it remains a popular choice on the secondary market for its balanced noise cancellation and lightweight design.
Features and Design
Launched at EAA AirVenture Oshkosh, the
Bose Aviation Headset X
was a complete redesign of Bose's previous aviation technology.
TriPort Technology: According to , this design allowed for a smaller, lighter earcup while maintaining high-performance noise reduction.
ANR Performance: It effectively reduces low-frequency cabin noise through active noise reduction, while also providing passive attenuation.
Lightweight Build: The headset weighs approximately 12 ounces, significantly reducing pilot fatigue during long flights.
Connectivity: Various versions were produced, including models with LEMO 6-pin (panel-powered) or Dual GA plugs (battery-powered).
Operation and Maintenance
As a legacy electronic device, the AHX series requires specific care to maintain performance.
Passive Mode: According to the Bose Owner's Guide, if the ANR electronics fail (due to low battery or circuitry issues), the headset will continue to provide communication in passive mode.
Power Source: Battery-powered versions typically use two AA batteries, while aircraft-powered versions must be connected to specific aircraft power sources to operate correctly.
