No power even with a new battery

I have this problem too. They stopped working and replacing the battery didn’t fix it so I shone a light down the battery compartment and I noticed a thin black wire that is soldered to the spring of the battery terminal door has managed to get chopped by the door itself and that’s the problem.

I have a similar problem. There does not seem to be a bad connection but when I put a new battery in the noise cancelling does not work. There does not seem to be any corrosion in the battery compartment. Can anyone help on how to get the headphones to pieces? I can at least look at the connections etc to see what is going on. Thank you.

Same problem. It gains power when the door is about 50% closed, but either side of that it cuts out. Can anyone help?

The light is off even I replaced with a new battery. However, after pressing the door a little bit, the light is on again. So for me it was a connection problem. The solution is just to close the door more firmly.
