Sennheiser CI 1

What can be said about this particular cable? I understand that it's best to have the real deal, but I bought this just because the 3.5 mm screw-in connector costs 15 euros, which is 3 euros less than this whole thing ande the spare ones I made weren't holding well inside the input of the transmitter. I make my own cables, but it would've cost me more if I had to buy everything separately. There must be a better way to connect your wireless unit (thinking about a 6.3 mm connector into the Neutrik locking jack), but it seems that nobody thought about it yet and you can't command 18 euros for a simple patch cable. The rating goes down just because of that 3.5 mm connector's undeserving holy grail imagery they try to force on us.
