My original AKG wired headphone does not work. The phone does not recognise at all. The usb c port can be used for charging but when i use headphone nothing, the sound come frome the phone speaker. I havent got water damage or anything like that. It happend suddenly in one moment i was listen music then just stopped and since that, doesnt work.
confirm that the headphones are still functional and not damaged, check with other USB-C port devices/phones first.
If the headphone is fine, then go to UBreakIFix to get the port on the phone checked out. Batteries Plus is another option.
Please follow up whether the issue still persists 🙂
