Don’t get me wrong. Apple removing audio jack was the biggest facepalm in smartphone history. And you can thank it for not being able to make an upgrade without sacrificing audio jack (and SD card too :/). But USB-C is getting standardized everywhere now (laptops, smartphones, etc.). What makes USB-C earphones not worth the switch?
There is a huge part of the world wide population that uses their phones constantly and need to constantly charge the phone. As an example think of a parking lot attendent sitting in a booth, nothing to do but play on the phone all day…
