On my Bose QuietControl 30 wireless headphones, the green light stays on until battery is low then turn red. Button doesn't do anything. Cannot turn on or turn off
Welcome to the community. I would be happy to help get your headphones back up and running with you.
As none of the buttons seem to be controlling the headphones, the first thing I would recommend you do is a reset of the headphones. To do this what you would need to do is:
It would also be a good idea to try forcing any available updates to the headphones by using our Device Updater on a computer.
If you are still having this problem after trying these steps, the next thing to do would be reaching out to your local support team, as they will be able to resolve this for you. You can find the contact information at this link, by selecting your country/region and then the 'Contact Us' option at the bottom of the page.
Let me know how you get on.

I had a similar problem with recently bought Bose QuietControl 30. They were turned off, not charging, just lying on my desk when suddenly the green light starts burning continuously. No response when pressing any button or combinations, short & long press. Bose reset instructions not working, could not turn them on or off. But I found a solution:
1. Take a standard USB to micro USB charging cable.
2. Cut off the USB connector (the big one that goes into the charger or other USB ports
3. Strip / remove the outer layer. Don't cut to deep to avoid cutting the inside wires.
4. You will see 4 thin wires: RED, BLACK, green and white. RED= +5V, BLACK=ground
5. Strip the RED and the BLACK wire so you get 5mm - 10mm naked conductor.
6. Wrap the naked RED and BLACK wires so they are permanently connected. (short circuit).
7. Put the mini USB jack in the Quietcontrol 30 charging port.
At least in my case, the green light turned off. Leave this short circuit cable during a long time. (In my case 8 hours was ok, but it can be shorter.)
8. Turn the QC 30 on. Worked perfectly as before.
Try this at your own risk, because creating a short circuit is not a very logical way to solve things but It worked. It's up to BOSE to confirm if this is a good way to overcome the issue. @bose: I solved your problem, please send me 1 piece of every model you sell, for free :).
