This model is battery powered, has a straight cord and single U-174 helicopter plug with the dynamic mic for military use. The military model does not come with the Bluetooth feature.
The A20 Aviation Headset is engineered to be more comfortable and provide more noise reduction than any headset we’ve ever made, while still delivering the clear audio you expect from Bose. And now there are more features than ever, including: a Bluetooth audio and communications interface; customizable audio prioritization control; intuitive “plug-and-play” operation; a high-performance microphone and an optional coil cord. And at just 12 ounces, it’s still one of the lightest active noise cancelling headsets out there. No other headset offers this unique combination of features and benefits.
