I’m a little biased as I work for Bose but we still use a metal yoke and hinge.

Will admit the hinges on my QC ultra headphones have been pretty good.

The things that annoy me about them are:

Unable to switch off noise cancellation

The earphone cushions fell apart after 6 months

Custom button action can’t toggle an aware mode

On head play pause was buggy enough to turn the feature off

They semi regularly decide to reboot in the middle of calls and meetings

I’m assuming you are retail and not on the design / software side of things but if you have any power to pass the feedback up the chain plz do ❤️

I guess the quality has gone down because my Bose 700s don’t have any of those issues besides the ear pads degrading about every 2 years.
