Hello everyone,
I just got a FairPhone 4 after a long struggle whether or not to buy it since I’m not a fan of bluetooth headphones, especially when outside.
I therefore also got the official FairPhone USB-C to audio jack adapter.
The adapter works flawlessly with my over-ear-headphones and my stereo. However, they do not work with the smaller earphones I use while running or cycling. I tried two different models, neither of them work. Instead, a notification is shown that the connected device is charged via USB (which doesn’t make sense, since the earphones have no battery).
Interestingly, if I connect my over-ear-phones, play music and then quickly (within about a second) change to the earphones, they work for about a minute before the music stops again. So it must be working somehow. Changing the cable every minute however is not a practical solution.
The earphones themselves work, also at my friend’s iPhone using a Lightning to Audio Jack adapter.
I tried to toggle the developer setting “Disable USB audio-routing”, also without success.
Does anyone have any advice for me except buying new earphones (which will then again be a gamble whether it works or not).
Thanks in advance!
