Some do, and some don't. Look for headsets that are labelled as “Certified for Microsoft Teams” or “Certified for Zoom” to be 100% confident your headset will be fully functional with all of the features that those applications offer. Any Bluetooth headset will work with those applications, so look for a multi device Bluetooth headset that can transition without any problem between phone and laptop. The main difference between a Certified headset and those that aren’t are usually specific behaviours of the buttons which may be different depending on the platform (including changing the mute status in application as well as the headset) and link to different features such as specifically launching and answering calls on the app at the touch of a button. Before purchasing check the compatibility notes with your specific application and device, or if you’re still unsure you can always reach out to our tech support who will be happy to advise.
