Well, you do need to be specific because like 99% of headphones terminate in a 3.5mm jack or a quarter inch jack. You were referring to a vert very limited subset of headphones.
It’s honestly kinda dumb to buy a headphone, which only needs an analogue voltage signal to work, that terminates in usb-c. Specially considering that there are still loads of devices that don’t have that port. Even if a computer has it, it’s likely that it only has 1 or 2 of them which might already be in use. For example, my work laptop has 2 usb-c and I’m using one of them to charge it and the other to connect a monitor.
Inflation is a thing that exists. Saying that someone is bad simply because they want to update the value of their property is dumb. Also, let’s say granny wants to downisze. Should she sell her home for a value way below market and then be unable to buy a smaller home for herself?
