For several months, I have been using my AEG wired earphones with the FP-supplied adapter (USB-C to 3.5mm) connected to my FP4.
I can listen to music fine, however…
The mic on the earphones seems not to connect well during phone calls, as people tell me the volume is very low.
Also, the volume controls don’t always work.
I’ve checked all the settings, tried restarting, twisting wires, etc. No improvement.
I’ve tried searching to see if these earphones are supposed to be compatible, but can’t find that info anywhere.
