The first adoption of the UmeCobra mic. in the US Air Force was at Kirtland Air Force base on the flight lines where the UmeCobra mic. replaced the M87 microphones on the David Clark headsets and the users found a dramatic improvement in clarity. More and more flight lines of the US Air Force found out about these benefits and adopted the UmeCobra microphone and once the pilots learnt of the benefit from the ground crew, they worked with the appropriate personnel to get the microphone approved for in flight use. It is now deployed by the US Air Force in the air and on the ground in various squadrons all over the world
