Hi, I have several pairs of wh-1000xm3 which all need the same part. I need to replace the outer portion on the slider. I must say its an awful design by sony, because of how thin and how easy they break. I can't seem to find anywhere where they have the part in stock. So I have 2 questions. Where can I buy a replacement slider. Secondly, is the wh1000xm3 slider design same as the wh1000xm2, can the sliders interchanged on the two pairs? The picture on the right is the unbroken one. That's the piece I need.
