I have a pair of 8006 and i can't complain about comfort, noiselevel or sound quality . The only thing that's bugging me is that in one of my flyingclubs C172(1979) i have problems with the microphone and i can't get rid of it by adjusting the squelch.
Could changing the switches to a lower setting help with that too?
It works flawlessly in our two other C172 that aren't as old.
