Can the Bose A30 Aviation Headset be used in all types of aircraft?

Yes. The A30 is optimised for use in general, military and commercial aviation aircraft. It can be used in both fixed-wing aircraft and in helicopters. It can be purchased with different connection options, including Dual G/A, 6-pin LEMO and 5-pin XLR. The A30 is not recommended for open-cockpit aircraft where the headset is in the direct path of the wind and slipstream.
