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?
And just when you have everything setup with USB-C, here comes the new connection standard, USB-D. Eliminating the audio jack is about planned obsolesce.
Samsung propably could make an USB Type A phone and your DAC would still work. Thats what standardisation is for.
