Just did my first flight and was very happy with them. I could hardly use the original AirPods on flights because I would have to Jack the volume all the way up to hear anything. I have one of the Bose QC models, which I liked, but started leaving them at home just because I found them too large to travel with.
I’m able to keep the volume down well below 50% and comfortably watch a movie with the Pro’s.
