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
Compared to what?
Corded earphones that go in the ear would give you the same problem. You can buy over ear Bluetooth headphones, and the ones I use for work have a charger where one battery is in and one is charging.
Shokz batteries last forever and still let you hear surroundings, so they are go-to for leaving the house. And for just audio, phone battery doesn’t matter either.
No cables for Bluetooth, and I wouldn’t wear earbuds anyway.
Additional bonus: my wife and I used to dance before kids and we can connect TWO sets of headphones for same audio without having to be touching, or we can listen to same audiobook while walking.
Of course, no cable snags or tangles either.
