Have you tried using any of them with multiple devices? Not at the same time, obviously, but in scenarios like "listening to them connected to phone while on the bus, getting into your office, switching to listening to them on your laptop".
If not, I recommend you testing out this specific scenario. For a lot of the ones I tested, it becomes an exercise in patience and frustration. There were even some that refused to pair with more than one device at a time at all, meaning that every time you switch a device, you have to do the whole pairing process again. And that wasn't 10 years ago, i tested this less than 2 years ago.
And even the whole pairing process is annoying. Best case scenario, you can just pair them using the standard bluetooth settings on your phone. Worst case, you have to deal with some custom app (that you have to install on your phone) and do the steps from there (looking at you, Sony; I love your WH-1000XM over the head line of headphones, but ffs this is just bad UX). Contrast it with AirPods, where you just need to open the case and put them close to your iPhone. You do it once and then completely forget about having to do this ever again.
P.S. if your other device is an Apple one as well, it gets even more seamless. You don't need to pair it in that case, you just switch the audio output device on your macbook from speakers to airpods, which are already present on the list of audio devices (as long as you paired it with another apple device of yours first).
