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?
My new phone is a flagship and does have a headphone jack (ASUS Zenfone 10), but I will rarely use it. Sometimes it’s definitely convenient to be able to plug in some random headphones or speakers, but usually the port just literally collects dust. It actually filled up so bad on my previous phone, that any jack I plugged in didn’t stay plugged in. However, that phone is now 6 years old.
For that get a toothpick and just dig around in there. Same for the charging port if the connection is loose when plugged in.
