I’ve used many brands of these at various price points (and also usb-c headphones). They work fine for like a month, but the connection degrades over time (maybe it wears out or gets dirty?), and I haven’t found a way to recover stability once it starts to randomly disconnect. It’s super annoying because when it disconnects, the software doesn’t handle it well, and I usually have to unplug it, plug it back in, unpause the music, and hope it doesn’t do it again as I gingerly place it back in my pocket. Basically, I think that USB-c is just not as consistent or sturdy of a port when you’ve got the playback device moving around in your pocket.

Sony still uses them. Their security updates were sub par the last time I checked.
