Can I ask why you purchased them in the first place? They seemed very obviously to not be a $600 product from their announcement.
Are there any other over the ear headphones that provide great sound quality, noise cancellation, pair with computers and smartphones, and have a solid mic? I’ve looked at the Sony XM1000’s and from what I understand there is some issue with Windows where if you enable the mic, it goes into some different Bluetooth mode that degrades the audio quality coming out of the headphones.

You can definitely get "good"[1] sound quality + noise cancelling, but for me at least most decent non noise cancelling headphones sound noticeably better than my Sony XM4s, even at much lower price points. I'm fine with this though, because I use my XM4s when I need to focus without being distracted by background noise and they do an amazing job at that.
(There's also the issue of bluetooth signal not being as good as wired, and the DAC/Amplification needing to be built into the headphones but I don't think that's having as much of an impact on the overall sound signature - it hasn't been my experience when using bluetooth adapters on some other headphones, and using the XM4s wired).
