BOSE A20 Non Bluetooth Headset - Helicopter U174 Plug - Straight Cable

Bose A20 Headset

The Bose A20 was designed for best-in-class active noise reduction — and provides ANR that’s 30% greater than conventional aviation headsets. his version is the NON Bluetooth option comes on a coiled cable fitted with a single U174 Plug for use in Helicopters.

Helicopter plug - helicopters use a single, shorter plug (that is not compatible with airplanes). This is not like the 6-pin plug however since an ANR helicopter headset will still need AA batteries.

Bose has set the standard in aviation headsets for over 20 years, with innovative noise reduction technology and unmatched comfort features. At just 12 oz., the A20 is one of the lightest headsets on the market; combine that with its soft sheepskin on headpad and minimal clamping force and you can wear this headset all day.

Bose's proprietary active noise reduction cancels an impressive amount of engine and propeller noise, but maintains outstanding battery life. The fully-adjustable microphone can be connected to either earcup and set in a range of stable positions for optimal communications. The Bose A20 is certified to FAA TSO-C139 and EASA ETSO-C139 standardsa nd comes with a 5-year warranty.

Next-generation pilot headset
More than 20 years ago, Bose introduced active noise reducing headsets to aviation – and launched an entire industry. Year after year, pilots have made our headsets their #1 preference. Now, the A20 aviation headset introduces an entirely new standard.

Enjoy a quieter flight
Proprietary technologies in the A20 aviation headset reduce more noise than ever before, across the full spectrum of human hearing, in even louder environments. Advanced electronics now use microphones both inside and outside each earcup to sense and reduce more ambient sound. Watch video.

Improved Bose ear cushion technology helps further reduce unwanted noise. New cushion materials block more sound before it enters the earcups, providing an even quieter headset experience.

And even greater comfort
The A20 aviation headset also provides a new level of comfort and stability. The overall headset profile is more compact, but the earcup cavity has been enlarged to allow more room for the ears. These proprietary cushions improve the earcups’ acoustic seals, even over eye glasses, and remain comfortable during long flights. The solid magnesium headband is extremely durable, yet lightweight, and its sheepskin cushion eliminates hot spots.

All these improvements have been achieved without increasing the headset’s weight or clamping force. The A20 headset weighs just 12 ounces and exerts significantly less clamping force than most active headsets.

Smart power control
The power system in the A20 aviation headset includes a smart shutoff feature that helps provide at least 45 hours of use from just two AA alkaline batteries. With the installed version of the headset, the technology intelligently switches from aircraft power to battery power as needed.

For all types of aircraft
The A20 aviation headset is available in an installed, aircraft-powered version and in portable, battery-powered versions for various craft, including helicopters.

Warranty
All Bose aviation headsets come with a 5-year warranty
