I have 2 main problems with that:
- My headphone cable is long and sometimes it gets tangled in all sorts of places. The adapters are small and flimsy, if I leave them on the cable I assume they'll break soon. I have no problems with a broken headphone cable as it is an easy and cheap fix. I don't think the adapters are seriously fixable tho.
- Everything else uses a headphone jack everywhere. I have yet to see a use for USB-C to audio jack anywhere else. Which makes sense as USB is digital and audio is analog. I assume many people have no use for headphones outside of their phones, I am not one of those people.
I don't intend on turning this into some sort of fight but to me your comment has big
"I don't see the problem why can't other people just have enough money"
vibes (Also I checked and an adapter costs me 12$ on Amazon). I don't think you intended it this way, so I'll shut up now.
As to my actual answer:
I could go on, but there's honestly no point. We're different people with different uses for our phones/headphones. I won't buy a phone without a headphone jack as long as I still have wired headphones.
