Question: I have a pair of Grado SR80s and the cable has shorts in two places. So I'm thinking of trying this as a solution. 1. Buy an IEM cable like this: cut off the two plugs at end of cable. Cut the Grado cable short, right near the cup. Solder the cables together. Use heat-shrink tubing to cover the solder point. Will this work? And will it be pretty easy? Is it just one wire in each half of the cable?
