Indeed... basically any mention to FW downgrade is against the forum rules.
so... my advice would be to run the win10 BT troubleshooter and, also, test if the headphones work fine using a mobile phone.
I think that they don’t like the fact that the solution involves doing something with our private property. Like commies...
btw, they erased another post of you.

Yes I agree, except that I don't expect to pay (near to) top $, to subsidize their softwarecdev when their marketing budget stretches to be a Mercedes F1 Sponsor! Bose have got their priorities upsidedown imo....their brand will lose value and buyers like me in the medium/long-term

Ok... This was just sad. Bought my head seat just an hour ago. Came home, put htem on, really satisfied. The I updated as I am used to with all modern electronics. And now there is noise that CRT TVs used to make when they had no signal and was all black and white scrambled pixels.
It resembles the noise that came when I tried to connect to my Linux computer and after the updated I wondered why this noise just reduced in intensity and did not disappear. So I googled, and here I am. Had I known I would not have upgraded to 4.5.2. The product feels sort of ruined for me now.
Replace them, they have to do it. It’s their fault.
or do what i’ve did (but they erased my post).
i had the same issue, so... i applied the 4.1.3 firmware. Now they are usable again.
