Now the phone standard is IP68. There were no IP68 compliant headphone jacks until recently, I think the ASUS Zenfone 12 is the first one.
The phone I’m literally holding right now (Xperia 5V) is IP68 compliant and has a jack…
it went away, and phones still sold like hotcakes
Well yeah, you basically need smartphones, it’s not very optional. What’s your point?
While those with headphone jacks aren’t being bought anywhere near the same volume. So the signal is very clear
There are very little options with headphone jacks so yeah, your math is on point. Lol. How can a product that doesn’t exist sale in high volumes?
It is a feature that doesn’t drive sales. Period.
Correlation is not causation.
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.
