As per the topic. I am doing a rebuild of some ratted out grado sr 325s. I am pretty happy with the direction I am heading in. I started with some four wire mic wire as my main length of wiring... but I don't really want a 1/4 in jack. And this doesn't seem to be working with any of the like 12 different jacks I have tried. Digikey seems to be lacking in options as well. Figured I'd reach out before I started considering new wiring options. I am also looking for a replacement for the twisted pair I am using for the over the head connection between driver cans. https://imgur.com/gallery/VpEgD has some photos of what I am working with. I am planning a second build after this with some more ratted out sr 325 drivers I have... so I'd like to lock down this design first.
