The functional difference was also a bit of a mystery to me. What I can say in addition to the previous speaker: The MS Teams model still has a Teams logo on the button on the outside of the right ear cup.

What the differences are according to the Jabra website is there. I can say that the MS Teams model supports a few Teams functions, e.g. accepting calls by pressing the button on the right ear cup. Hope that helps a little. Otherwise: https://www.jabraheadsets.ch/supportpag...
