Product Features (**)

Significantly improved noise reduction across a wider range of frequencies. Proprietary Bose innovations now use microphones both inside and outside each earcup to sense and reduce more ambient aircraft noise.

Redesigned ear cushions deliver greater comfort using new materials. More compact earcups now have a larger interior cavity, allowing more room for the ears; redistribution of headset weight also helps improve overall comfort and stability.

Enhanced center torsion spring on magnesium headband provides a consistent, comfortable fit for any size head with significantly less clamping force than most pilot headsets.

TriPort® acoustic headset structure, available only from Bose, produces tonally balanced audio from relatively small and lightweight headphones.

Active equalization electronically tunes the headphones' frequency response, enabling outstanding audio performance.

Adjustable powered microphone can be connected to either earcup and set in a range of stable positions for optimal communications.

Auxiliary audio input on redesigned control module for connection to GPS and other devices. Pushbutton Intercom/AUX enables priority switching

Bluetooth phone connectivity lets you take calls wirelessly through the headset (optional).

Enhanced EMI protection to minimize communications interference.

Integrated sidetone for more natural sounding intercom and mobile communications.

Smart shutoff for extended battery life. Installed headsets also feature a flexible power system to automatically switch from aircraft power to battery power as needed.

Ergonomic control module has been redesigned for greater ease of use. Includes contoured grip and streamlined interface with high-contrast icons on main controls.

Custom carrying case helps protect headset during storage and transport.

TSO certified by FAA/JAA to meet performance standards for headsets used on civil aircraft. Made in the US, it also meets RTCA/DO-160D and DO-214 environmental requirements.

Five-year transferable limited warranty covers parts, labor and second-day return shipping expenses for non-abuse malfunctions.

(*) Note on Headset Connectors:

The GA Plug (also known as a General Aviation Plug, Twin Plug or a Dual Plug) is the mostly used headset connector for general aviation/fixed-wing aircraft like Cessna’s, Beechcraft’s, Cirrus’, Piper's but also in some newer aircraft, like Cirrus or Mooney. While these are the most universal of plugs, it is important to know that the plugs themselves will not provide power for ANR (Active Noise Reduction) or Bluetooth. When using a GA Plug headset, 1 plug will provide the audio to the ear cups and the other will provide the power to the microphone. Batteries will power ANR, Bluetooth and Amplification functions.

The U174 Plug is a helicopter plug. This is a single plug and looks similar to a GA Plug but it is shorter and thicker than a GA Plug. This single plug will help supply power for the ear cup audio and the microphone. Like GA Plugs, a headset with a U174 Plug will not power ANR or Bluetooth if the headset provides these options.

Panel Powered / Redel / LEMO Connector Plug allows pluging of any Redel equipped ANR (Active Noise Reduction) headset directly into the panel. This single 6-pin jack will provide audio, microphone, as well as power for the ANR in the headset so you can skip the batteries.

XLR 5 is a five-pin connector used in aviation headsets, where it can supply power for active noise cancellation.
