Don’t need the dock. I just directly connect it to my work laptop or even my Chromebook. Windows and ChromeOS recognize it as Roger On and stream audio. I just it just for the audio as well at Teams/Zoom, and I use a separate podcast-style condenser microphone or the mic built into my webcam for my voice.
I even plug into into my tablet’s USB-C when traveling, as Roger’s protocol uses far less battery than Bluetooth classic.
