Phone earphones remote hack - eried - 05-30-2016 04:29 PM

I like the in-ear fit samsung earphones ( http://www.samsungstore.cl/audifonos-in-ear-fit-black.html ) but they don't work properly on my beloved Lumia 950 (the volume button mapping is wrong) ... but it shouldn't be so complex to hack, right?

The buttons are just a resistor in line with the MIC:

Certainly, there was 5 resistors in the earphones-control PCB, 3 related with the buttons and I just used a broken earphone as a donor for the resistors:

So, in conclusion if you want to adapt an earphone from iOS/Android/Windows to another platform, it is just a matter of switching the resistors... the tiny resistors (normal thru hole resistor as scale):
