Lenovo and some other computer manufacturers have started using a 4-pole 3.5mm combo audio socket for microphone and stereo headphones, evidently the same pinout (TRRS?) as used for original and 3G iPhone, Blackberry and some other smartphones.
Having had a hard time finding a PC headset I like, I want to stick with it and thus need to adapt from its conventional 3.5mm stereo plugs to the combo plug. There's a ready made solution here but of course they won't ship to NZ. Has anyone found an NZ source of this sort of adapter?
