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
Apples dongle is $10 and very high quality. It uses the same chip that was previously internally in the iphone. Good adapters aren’t that expensive.
Dedicated DACs for phones started taking off right as the 3.5mm jack was getitng killed anyways. All the hardcore audiophiles I know that listen to music on their phone use one of those because they can actually drive good headphones. It was kinda perfect timing.
