My headphone quality requirements are slim to nonexistent since I mostly only use them on planes and trains to listen to music and block out noise, but my form factor requirements are pretty strict. I currently use Anker Soundbud Slims. I like the wired necklace and the magnets on the earpieces that allow the necklace to be sort of completed, although they're very weak. I pull out one earbud pretty often when I need to hear something, so the necklace lets me just drop it instead of having to faff about with storage. I guarantee I would lose individual detached earbuds pretty quickly. I don't use them for videoconferences, so I don't need a microphone. When I did my USB-C unification the closest equivalents tended to have solid plastic necklaces for more structure and mic mounts (looks like one of your recs has this?), but I store my headphones crumpled up in a tiny pocket. This was a year or two ago so maybe there are better options now, but at the moment my headphones just have a permanent adapter attached to them.
