Re: Bose QC 35 ii firmware 4.5.2
Sony XM3 latest firmware update 4.1.1 added support for Amazon Alexa and owners complain of degraded noise cancellation feature.

I still think the Alexa support affect the microphone to be always on (to support picking up commands).
From Bose forum (about the mic picking up sound during calls):
”The microphones are tuned to the human voice frequency range. They automatically adjust the gain (microphone volume). In a loud environment where there are voices in the background, it is possible the microphones will pick up those background noises and bring up the gain.”
I have not upgraded, and will stay on 4.1.3 🙂
