I've used the Poly Voyager Focus, Poly Voyager 6200 and Shokz OpenComm (with Avantree DG80 dongle) with good results. They don't require custom software, but they do require using the provided dongle (or 3rd party dongle for the OpenComm) because PulseAudio doesn't support wide band speech. Installing PipeWire is another option (or waiting for your distribution to switch to it).

With a 3rd party dongle like the Avantree DG80 you can use any bluetooth headset and don't need to worry about the Linux support part. The main disadvantage I found is that you have to manually switch between headset mode and HiFi headphones mode.

I also have the Poly Voyager 8200, but I haven't used it as a headset enough to give a definitive assessment, but based on what I've tried and the results from the other Poly products I expect it to be good.

I also tried the Poly Voyager 5200, but I didn't like the speaker sound quality with it being a single ear device.
