Thank you for taking the time to post and welcome to the community!
I'm sorry to hear of the issues you are experiencing with your QC35s. I'll be happy to assist you.
I would recommend clearing the Bluetooth pairing on the headphones and deleting the pairing from your source device. Then re-pairing the devices as if it was a new connection. I have included some instructions HERE to assist you.
Secondly, make sure the firmware is up to date. You can download the latest update Here.
If this is unsuccessful in resolving your issue, I would recommend reaching out to our Technical Support Team for assistance. You can find the details by clicking HERE, selecting your country of residence and scrolling down to 'Contact Us'.
I hope this helps.
Have a great day!

For the first time i bougt expansive headfones, and for the first time i have i serious problem with my headfones, my
QuietComfort 35 II
Cant keep a clear bluetooth signal if im 2 meters away from the device....
I have tried this....
Turn the headset off and wait for 30 seconds. Plug the headset into a USB power supply via USB cord and wait 5 seconds. (Power supply needs to be plugged into the wall with power on). Unplug USB cord from headset and wait 1 minute. Turn on the headset and test if the headset works properly. After you have completed the reset I'd like to clear the paired list on the headphones and reestablish the connection. To do this you'll slide the power switch to the right towards the Bluetooth symbol and hold it for about 10 seconds, you should hear a voice prompt notifying you that the list has been cleared. At this point make sure to remove the headphones from your device's paired lists completely. Once you have done this you can reestablish the connection.
I have been using 50dollars headfones with out problem, but when you buy headsfones for 300dollars, you would tink you were buying quality 😔

Similar thing is happening with me. It keeps on disconnecting and reconnecting randomly. I bought this in year 2018.
Other than that the wire that comes bundled only support audio and not two way communication.

I am facing the same random disconnection issue.
i have tried all suggested solutions from clearing the device list to downgrading firmware to reinstalling and re-adding all the devices but the issue persists.
the issue started 06/07/2020. Reading the thread and similar other ones lot of consumers have started having this issue is May/June of 2020
Thanks for posting.
I am sorry that this is happening, the troubleshooting you have tried so far is great. Please can you let me know if this issue occurs across multiple devices? If so, the best option here would be to reach out to your local customer support center and explore the service options for your headset. You can do this by clicking this link here, selecting your region, scrolling to the bottom of the page, and selecting contact us. If you are in the US or UK you can also reach out via Facebook or Twitter and one of our team can help you there.
I am sorry that we could not help more via this platform.

This happens to me all the time. It happens on both my phone and my PC. I have removed all connections and reenabled. I tried updating the drivers on my PC. That did not fix the problem. Same as someone else, my cheap headphones don't have this problem. I love the way the Bose sounds, but this makes it unusable! Unfortunately it is enough for me to start researching other products.

I am also having this same issue. It started about 3 days ago. This is extremely irritating when trying to have a conversation, or speaking during a conference call. It happens across multiple devices (Pixel 3, and Windows 10).
