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?
I would need to replace my headphones, too. Right now I’m able to plug in my studio monitors, my earphones for biking, my wife’s earphones, my kid’s, my spares, … I can buy cheap replacements, or repair then easily. Kid kept breaking his so I started repairing them, which turned out to be almost trivial. Mostly wires getting loose in the cups or the plug itself.
