When I first got a phone without a headphone jack, I bought one such dongle. It didn't work. My two subsequent phones have had headphone jacks, so I'm not going to worry about this problem again for a while, but at the time at least it was certainly not as simple as buying a dongle and knowing it would work.
Every answer here is "buy this other thing, no wait, that may not work for your use case, buy this other thing to lug around or that makes your laptop effectively a desktop".
This is strictly worse than the previous status quo.
