After traveling the past week with a couple of long flights I am returning the B&W PX7 S2e and PX8 cans I tried and keeping the Focal Bathys. The Focals sounded better. The hearing test and customization they have worked well for me. They were also more comfortable than even the Bose on the long flights. Wore for hours with no issues beyond a little ear pressure but that’s flying. I am also keeping a pair of Sonos Ace for use at home with my two Beam 2 and mini sub setups since I can pair and listen to TV at night without disturbing anyone. BTW all of the cans were bought used on Amazon and compared to new models. Much less expensive and looked unused. Keeping both pair for the cost of new Bathys.
