More terrible than needing a converter for every pair of wired headphones, and a separate converter for the highly advanced case of wanting to charge my phone while listening to music?
Yes. There are valid reasons for not including a headphone jack whereas there are none for having two incompatible connector types (USB/Lightning) for the same purposes. It would make more sense to encourage manufacturers to make variants of their headphones with a USB plug (AFAIK USB-C supports analog audio). Mandating that all phones must have a headphone jack would make sense if manufacturers omitted it for antico…
I guess that's a matter of opinion, because I am convinced that this is exactly what happened. Apple sells dongles for money and also makes money on Lightning licensing.
