So a few weeks ago I heard that a line of Bose soundbars had been having Firmware issues and becoming bricked due to new firmware being installed Link.
Now today I’ve just heard that a similar issue is happening with their headphones Bose QuietComfort 35. Firmware update killing the noise cancelling functions.
I had no idea this was a thing as I never bothered to use their app to update my headphones firmware.
