I have purchased five or six different pairs of Bose noise-cancelling headphones, but I will never buy another product from them again until they allow customers to revert firmware.
I updated the firmware on my QC35s a couple of years ago, and the ANC got worse. Like, maybe 6 decibels or so worse, with strange white noise. I wrote to them explaining the problem and asked how to revert firmware, and they said it wasn't permitted and instructed me to "turn the device off and on" or something like that as a way to pretend to address the issue and make me go away.
I have only owned two products whose manufacturers refused to solve the problem when a new release of software or firmware ruined the user experience. The first was my Google Nexus 6P that boot-looped itself to death upon startup after an Android upgrade, and the second was my pair of QC35s.
Since then, I don't trust Bose's updates and refuse to update any of my other devices made by them.
