I see a lot of people complaining that the Fairphone 6 doesn’t have an Aux jack.
Just use an adapter cable.
A 3.5mm Aux jack takes up a significant amount of space just to connect a few wires that could be connected through USB-C anyway, that space could be used for a bigger battery.
Even if there was a good enough reason to keep Aux it should be 2.5mm Aux and not the usual 3.5 as it does exactly the same thing but uses less space
My dongle that supports charging and analog audio for my car has a whine that changes pitch with the motor speed (guessing it’s very sensitive to the voltage or frequency of the alternator or something). Though at least it’s low enough that it’s almost unnoticeable when actual audio is playing.
It also requires the phone be unlocked to start sending audio through the USB interface. And maybe about 10% of the time whe I get it all set up and music/podcast playing, the motion of hitting the lock button on my phone to turn the screen off also bumps the usb port enough for it to briefly disconnect, which stops my audio and forces me to unlock my phone again to get it playing through the cable.
The phone needs to have a DAC anyways if it wants to drive its speakers. I could live with a smaller analog jack, but hate having to use a separate device with its own DAC that is probably way cheaper than the one already in my phone plus they probably don’t even isolate the audio signal from the charging signal because the main selling point is just the ability to play audio and charge at the same time.
