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
What needs to happen is the underlying direct feed path needs to still exist, but a modernized connector to bridge it. Because you are right, people don’t understand just how much area the connector port requires.
I have no idea what it takes to bring such a thing to market, but I know that from a hardware perspective you’re looking at two wires.
