Hey everybody,

Today I was about to switch out the battery on my old pair of Bose Bluetooth headphones. I soldered the new battery, turned them on and all of a sudden this noise came out of them like 2 seconds after I turned them on. Now it comes on every time I turn them on.

I figured out that the noise stops completely when I touch that little part you see in the video with my plastic spudger. Can anyone explain what is happening and hopefully offer a solution to this problem?

Thank you guys in advance
