A USB-C to headphone adapter is $5.
My biggest issue with it is that it's been sold to us on a lie - the whole nonsense about "reclaiming the space" - it's BS. There is space for it in nearly every phone on the market.
I'm feeling like a dinosaur pointing out that I still have headphones which just work and there is literally nothing wrong with them. I own two pairs of bluetooth headphones too, and they are great - but let's not kid ourselves, there are drawbacks to it too.
