The Bose Aviation Headset X marks a departure from conventional thinking. Standard technology often requires a choice between comfort or more noise reduction. This headset is engineered differently, to work as a system that improves both noise reduction and comfort.
You can choose from two headset configurations. The portable version can operate for 20 hours, and its control module requires only one 9-volt alkaline battery. The installed version conveniently works with the Bose installed interface. Other options include an electret ( the norm) or dynamic mic (mainly for military helicopters) and straight or coiled cables. The dynamic microphone is only available with coiled cord. There is a choice between panel mount (LEMO), general aviation and helicopter (U-174) plug connections.
In addition, the earcup connector allows you to conveniently switch the boom mic and cable to either earcup, and to use different cable configurations.You can choose from two headset configurations.
