Watch out if you go the adapter route. I bought adapters for my rear seats haedsets, albeit the other way round (bronze female to silver male). They did not work. After a bit of searching, I found a wiring diagram and it turns out that the adapters had been soldered wrong: the various connection points are different bronze to silver.
