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?
When companies began to drop the audio jack I was annoyed, but I figured I could just buy a converter. Which would be great if there were a universal standard for connecting audio through a USB C. There isn’t. There aren’t even just two competing approaches. There are all kinds of different setups that sometimes vary even within a single brand.
I found multiple adapter that said it supported my phone brand. It didn’t work. I looked deeper and found some advice on adapters that would work with more recent phone. I bought one based on that and it worked, sort of. The audio quality was not great and it would occasionally just cut out for a second. My third try got me an adapter that work reliably, but the audio quality is still mediocre. My best headphones are all analog, but I have to use Bluetooth with my phone because it provides better audio.
The physical issues, particularly the connectors, guarantees that USB C will never work as well. The lack of standards for implementing it make finding compatible hardware a nightmare. And if you manage to get everything else figured out you end up with the kind of sound you can hear from an audio jack using a $5 set of earbuds. It provides no benefits to the user, only to the manufacturer.
