I am trying to replace a broken cable on my headphones(Sennheiser HD 280 PRO) but I can't figure the type of cable so that I can order it online. I think it is pretty standard as it seems other headphones have similar cables. However searching for headphones cable only helps to find replacing connector cable(i.e. the one connecting the headphones to computer) but not the one connecting the two parts(speakers).
This is a picture of the cable. One part is varnished(maybe not the correct word in English). I don't have a caliper, but I think the tickness of the cable is about 1.5-2mm.
Could someone please tell me what kind of cable is this?
EDIT: adding two more pictures of the end of the cable:
The while bit that can be seems is more like fabric, not wire.
