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?
It’s rechargeable.
Point #2 at the top of this thread: OP doesn’t want yet another device to have to recharge all the time.
