It looks to the PC like USB audio, but it talks to the headphones over Bluetooth.
If I want to transition from the Windows 10 laptop to the Linux laptop, or desk-side PC, I just move the dongle.
Signal is solid. Has an LED on it so you can see whether it's talking to a headset (blue), playing audio with mic umuted (green), or playing audio with mic muted (red). (Amazing feature for Zoom calls!)
The retail price of it seems a bit high at $56, but you can find them used with Jabra Evolve 65 headsets on eBay for $45-$60 as a bundle. (The headset sound is pretty good, actually. Fragile if you don't pack it flat in a backpack, alas.)
Sorry I sound like a commercial, but it really makes life easier. Seems like the frustration saved was worth the $$$.
