Hi, Chris!
I hope you resolved problem and fix your headphones?
I was able open this box - housing is opened only by cutting the rubber sheath.
But I have cutted cable from headphones side(torn cable)
And 6 out of 12 cords I have no idea how where to should be connected(
I would be grateful if you could take a picture or paint contacts connected!
Thank you very much!
Best wishes!
