As a head's up, unless you have a solder pot to tin the wires, you're likely to not be able to solder a connector onto that stock cable as it uses a litz style wire.
I didn't know there was such thing as a solder pot, or that these hard-to-solder wires had a name...haha. I just watched a youtube video of a solder pot, and I sort of want one now. But I've been able to solder the m50 cable before. It's difficult, but I kind of have a technique down.
Also, the headphones are on hold for Bunny until I can get him a more accurate shipping quote.
