Can I use this tool to test my headset for Teams?
Yes, it checks your headset speakers (left, right, center, and frequencies) in the browser. For your microphone, use the Make a test call button inside Teams.
Why do my Bluetooth headphones cut out in Teams?
Teams uses both speaker and microphone profiles over Bluetooth, which can lower audio quality or drop if another app holds the mic. Make sure only Teams is using the headset.
Do I need to install anything to run this audio check?
No. The headphone test runs directly in your browser with no sign-up or downloads.
