Not really the point, it costs, people need to buy it, not doing it is easier.

My wired headphones (Sony MH410c) cost me three euros. But those were often included when buying a Sony phone. A decade ago you automatically had headphones when buying a phone.

Still doesn't make it alright, but it's let's accessible now and I can see that leading to a societal change.

Pro tip. If you turn the volume down and hold it to your ear you can still listen to whatever without anyone else hearing. Like we used to be able to hear the other end of the line without others hearing in the old days when we used phones to phone people.

My phone literally doesn't support those, pops up a little warning and everything.

USB Sound card with an OTG adapter works but like, come, that's horseshit.

Sweet, now how do i put a USB-C port on my phone
