Its definitely the driver. I switched the cables to each driver and both cables worked with one driver, not the other. Also when checking the drivers with a meter, the good driver read ~30 ohms and the other one nothing. I am really still perplexed what I actually did to break the driver. If I had to guess though, it has to do with the white goop between the two contact pads. I must have hit that more than I should have with the iron.
I can do everything fine except precise soldering. I come from a long line of shaky people and never would have made it as a surgeon. The cable actually looks great, but I can only listen in Mono though. This whole scenario is particularly disappointing because I have been busting my butt on my new cups the past few days and I also have a new Beyer headband coming in, both things I have been waiting a while for. Now they will have to wait until I can find an extra driver, something I am not confident I can do quickly. Seems like not many people have extras unless they aren't advertising them.
I'm going to be like a kid sitting in a car making car noises, but not going anywhere.
