got the A20 today.... not tested in flight yed but i'm impressed by the overall quality! a very nice piece of equipment!
The ANR feels better than any other active headset I had in the past : Bose Aviation II, Aviation X, and my loved ANR-fitted DC ( the one I liked more)
Kinda love the new bigger earcup of the A20 ( my head is comparable to a zepplin hangar LOL )
Tested the blutooth capability during a phone call and WOW!! amazing they have their own side tone! even if not connected to the aircraft
I have also tested the audio IN using my I phone and I have to say the quality is better than many many "studio" headphones!
Well.... I'm on the night time shift, let's see if I can test them in the air tonight
