Cần micro thay thế cho Jabra Evolve2 85 (Đang phát triển)

The boom arm on my microphone is cracked. It seems to be a common problem. Jabra doesn’t provide replacements outside the warranty period (I’ve asked them).
I have this model. The outer casing fits very well. I’ve taken the whole microphone apart, which isn’t a problem.

Remove the padding, loosen the four screws, very carefully peel away the adhesive from the microphone connector, and pull out the bolt at the microphone’s pivot point.

I need some help from here on.
I know there’s a flex cable with a PCB inside, with a button and the two microphones on it.
The whole thing is quite firmly attached – probably glued. I need the internal dimensions, so I can’t just force it open.
And I’m worried I might damage the electronics as well. There aren’t any useful pictures of the inside online.
Has anyone here taken the Arm apart yet?

Thank for your help
