I'm building an Ergodash which requires a MJ-4PP-9 socket and a matching TRRS cable. I believe I've got the right female with the following dimensions.
However, all the male-to-male cables I've got have the copper/brass part 15-16 mm long, which doesn't fit the 14.1 mm long MJ-4PP-9. I've tried searching around and all the 3.5mm TRRS cables seem to have about the same size mismatch. I've tried searching for a MJ-4PP-9 cable but got nothing.
How should I search for the matching cable for the MJ-4PP-9?
