With the new iPhones and USB-C this becomes pretty much a non-issue. You can keep the Apple USB-C to headphone jack adapter on the headphones permanently and most devices can make use of it. It works on every smartphone, it works on my Macbooks, it works on the iPad, and I'd hazard the guess it would work on Windows out of the box. And that adapter has good audio quality and is also among the cheapest.
I fully agree that this topic is a nightmare when it comes to lightning. Good riddance lightning...
There is still the inconvenience with the charging, especially if you are on the go charging with a powerbank or waiting at an airport you won't have wireless charging. There is a workaround that's good enough for me, any modern tiny (GaN) 30W charger can charge any iPhone far enough in 20-30 minutes.
I am not drinking the kool aid saying it's good we no longer have a headphone jack, it's inconveniencing us for no good reason. It doesn't affect water resistance, that and all other manufacturer claims are just not true. But it's an inconvenience I can live with as long as it's USB-C and not lightning.
