Which headphones, headsets or external speakers are compatible?
There are different standards in using 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 FP2 uses the standard AHJ=CTIA (ground=2) - on the right image above.
Fairphone does not have the capacity to test headphones and is not in a position to endorse the use of brands or types of headphones. Our awesome community helped to make a nice list of good headphones that they have tried out.
What if my headphone is not working on my Fairphone 2?
If you are using compatible headphones (see above) and the sound is not working, please verify once again if your head jack is damaged. Try at least 3 different headphones to check if it is really the head jack of the Fairphone 2 and not broken headphones.
Also, be sure your headset/phones are suitable for Android devices. Head sets made for other phones than Android based phones might not work.
