I have been using the Bose ProFlight for about a month now. The very first trip with them I was certain that I would be returning them ASAP. I gave them a second chance and have now fallen in love with them. The noise cancelling works very well...even in a noisy CRJ. The “hear through” function is a good idea but worthless in the real world. I have finally found out how to turn it off so that every time I touch my ear it doesn’t turn on and become annoyingly loud. The cord is a bit heavy and cumbersome but I just clip it on something and it relieves the pressure. The only thing I really hate about it is the carrying case. It takes extra time to neatly fold it all up and store the headset after each flight. Maybe they will fix that during the next version.
