So did anyone ever try using a different stereo cable to link them together. I would love to know so I could save some money and get the lengths I want.
Yes it works fine.
Just get a 3.5mm 2 pole stereo male to male.
2 poles = 2 black rings around the plug, somehow there are 3 poles ones out there, single poles are mono.
I am looking for something like this (below) without the ugly coil. That 90 bend looks sharp without sticking out.
