Though being able to use the right tool, in circumstances where that is a wired set, can be a problem on some platforms.

This is true (iPhones, iPads, and plenty of Android phones these days), but can be mitigated by carrying a USB-C to 3.5 mm audio adapter in the pouch that contains the IEMs. I wish people didn't have to, but it's a straightforward solution that widely improves wired compatibility.

> ... that widely improves wired compatibility.

"Wired compatibility" was ubiquitous before. It didn't have room to "improve". Removing the jack is what broke "wired compatibility".

Needing a dongle for sth is not an "improved" form of using it, when you could have just used it without a dongle.

Adding a small adapter to where you carry your wired headphones fixes the problem of the current reality where many devices do not have audio jacks. My assertion is to provide a practical solution to the current state of affairs, instead of claiming that the present is better than the past state of affairs (where there were ubiquitous audio jacks) due to audio adapters.

Due to forces beyond the individual's control, it's highly unlikely that audio jacks will once more become ubiquitous, so the second-best outcome is for wired headphone users to start carrying an adapter.

That's entirely besides the point.

The "right tool" might be an adapter or hub.
