I would love a Fairphone, but no headphone jack is a nonstarter for me. Still blows me away that a company saying they are focused on longevity would get rid of a universal audio interface that we've had for decades. In the article they claim it's to fit other features in, but frankly that's not a believable claim. Other manufacturers manage to get a headphone jack in just fine, without any noticeable downside.
I absolutely concour about the need of a headphone jack - I do not buy anything without it. So, > to fit other features in what exactly, one would ask. If there are tradeoffs, if would be nice if the customers can decide what to have, in a modular product.
Only issue is some very cheap ones are actually bluetooth headphones in disguise where the usb-c connection only exist to power the bt recepter inside the headphone. I find this completely stupid.
