FP3(+). Audio jack 3,5 mm


There are different standards for the 4-pins of a headset with mic (and remote). Here you can find the explanation about the different types and with a simple measurement you can check what wired* headset you have:

The Fairphone 3/Fairphone 3+ (FP3/FP3+) use the standard 3,5 mm AHJ=CTIA (ground=2).

Your device does not work

If your device does not work on your FP3/FP3+:

  1. Make sure your device is compatible with the FP3/FP3+ and, in general, Android devices. Headsets made for Apple devices might not work.
  2. If the sound is still not working, please check that your head jack is not damaged. Try at least 3 different headphones to deduct if it is really the head jack of the FP3/FP3+ that causes the problem and not a broken headphone.
