I have two of these stereo jacks that I am planning on using to rewire some headphones that have had the original cable fail somewhere between the speaker and the end plug. Instead of bothering to fix the existing cable, I plan to replace the cable entirely but also give them the ability to have a removable cable. The replacement cable has 1x 3.5mm stereo plug on one end and 2x 2.5mm mono plugs on the other end.
What I'm not sure of is whether or not there is an optimal pole to resolder when using a mono plug in this (stereo) jack?
For anyone curious, the final product:
