The PA18-72 has superseded the PA17-72 which has been a popular choice with Pilots due to it being a very lightweight headset; this headset has been put into retirement after 20 years.
Using proven advanced electronics, Pilot have made the 18-72 even more comfortable than the old 17-72 model. The 18-72 produces 30dB of Active Noise Reduction at 100Hz.
