I think he would have removed the headphone, it's old technology, but he would, like you say, presented it better.
I had my Earins for 6 months now and it looks really funny to see people wear cables. It's also inconvenient.
That said, there are some technical issues with wireless earbuds, if I turn my head quickly, the signal will drop. Sometimes it can be hard to make them connect, you have to pull them in and out of the case. Also, they need to be charged, which is an annoyance. If Apple solves these issues, I can't see people wearing cables in the 2020s.
The piece that is missing, I think, is wireless charging. If they could charge in my pocket, from my phone or some charger at the office or home, it would be really nice.
