I'm sitting at my desk working, wearing my Bose QuietComfort 35 II headphones (connected to my MacBook Pro and my iPhone X), when all of a sudden I hear "doo, doo, doo, doo 🎶", and the noise cancelling turns off! I.e., the headphones turned off all by themselves. This has happened about twice a week. What's causing this? Is this a known issue?
Thanks for reaching out, I haven't heard of any reports of this happening with other users. Are you actively listening to music or any audio when they turn off? I'd take a look into the "auto off" settings in the Connect app and make sure that it is set to "never". The auto-off will only occur if there is no audio being transmitted.
In addition, let's try a reset on the headphones:
Let me know if this helps?
I hope that you enjoy the rest of your week!

This happens to me as well.
The use case is when I am connected to my work laptop and on a video conference.
It is as if the Bose Quietcomfort 35II does not recognise that the cans are in use and puts headphones into Standby mode.
I have now switched off Standby Timer on the App which is not ideal. Let to see if that is a fix for the issue.
This happens to me all the time too. Used to only occur with my laptop but now with my phone too. Incredibly annoying for £340. Very disappinted!

I recently encountered the issue with my Bose QuietComfort 35 II shutting off by itself, regardless of if audio was playing or not. I did not find a solution online that worked so I decided to visit the Bose website. It turned out to be a firmware issue which I fixed using the instructions below.
On the Bose website, click "Support", then "Over-Ear Headphones" and scroll down to click on "Downloads". Under "Software Updates", there a link that directs you to "Visit Bose system update center", click on it. Next, "Accept and Continue" and "Download" the Bose Updater. After it installs, the software will direct you to plug your headphone into your computer via USB cable. Allow the transfer to occur (mine took 5 minutes) with the headphone powered on and unplug the cable the cable once completed.
Hope this helps someone,
Hi, I´ve just got my headphones yesterday and it´s turning off by it self. So I supose it´s not a problem of updates. Can you give me any other clues?
I´ve just got my headphones yesterday and it´s turning off by it self.I´ve donne what you suggested and it´s not working. I also, since I downloaded the app yesterday I don´t think it´s an update problem.
What else can I do?
