It's neat, but as I recall, requires removal of significant insulating
material from the cups.  IIRC ANR only works on low frequencies so the 
removal of insulating material really worsens the passive attenuation at 
higher frequencies, at least in my experience.

I should mention that you can make the telex mike work acceptably
in a Pitts cockpit if you have a mike muff (essential) and you also 
turn down the gain potentiometer in your radio.  At the same time
you can also crank up the sidetone slightly - they're typically set
too low for our noisy cockpits (and deafened eardrums :)

Peter, that worked out ok for you in your S-1T didn't it?
