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
Bluetooth 5 is 50Mbit/s it’s perfectly fine even more so past 5.4 for latency and 6.x. even better. So personally for me it’s good enough now. The battery life on my WF Sony earbuds has been enough to not annoy me at all. So, it’s better than a tangling cord.
