The cable that goes from the left side to the right cup of the headphones got broken and i want to replace it.
 
The thing is I dont  what cable to use.
 
I have found this one:

But I dont know much about cables and im not sure if it will be what i need, also do I need to get two strings for the  +/-?
 
Any help would be welcome

You will need 2 strands. I recommend you use 28awg or 26awg MAX thickness. There isn't a lot of room in the headband to route a thick wire, let alone 2 of them. You will see. 
 
PlusSound has some 28awg wire, that is what I recommend you use.

Definitely 28awg for that right channel wiring that goes through any Sennheiser headband.
