Good advice...I can just shave away the current plug. Excellent.
As for the rest I'll figure it out. The chart above shows the poles but not the internal pin layout. So you're saying that a 2.5mm 4-pole plug with 4-pins inside for L+/R+/Mic/Ground can't be used for L+/R+/L-/R- if I just put the wires to the appropriate pole?
A plain plug can be used, without any problems. It's just the adapters, which convert to/from 2.5mm & 3.5mm, that you have to be careful with.
To determine which solder contact is which pole of the plug, it's best to use an Ohmmeter. But typically, since the contacts are coaxial - the plug Tip is the small contact that's furthest from the Tip, and then working in, until you get to the Sleeve, which is the contact closest to the Sleeve (or sometimes it's the one with the wire clamp).
