Why does my wireless headset disconnect and reconnect when joining a Teams call/meeting?

Dear @Mike,

Thank you for reaching out to Microsoft Q&A forum.

I am truly sorry to hear about the disruptive issue you're having with your wireless headset disconnecting and reconnecting when joining a Teams call. As a forum moderator, I genuinely wish I could directly access your account or delve into the backend systems to diagnose and fix this for you. However, our role here is limited to providing general guidance and solutions that can be applied by users. 

The fact that you've experienced this with multiple brands (Jabra and Logi/Logitech) strongly suggests the core issue is not the headset itself, but a conflict in how your Windows operating system and Microsoft Teams are managing the audio devices, particularly when shifting focus to a call.

Here are the most common solutions to fix this conflict:

1. Set the Headset as the Default System Device

When Teams opens, it often tries to use whatever Windows defines as the "Default Communications Device." If your headset isn't set this way, Windows struggles to switch audio control, causing the headset to briefly drop.

1. Right-click the Speaker icon in your Windows Taskbar and select Sounds (or navigate to Settings > System > Sound > More sound settings).
2. Go to the Playback tab.
3. Right-click on your headset (e.g., "Jabra/Logi Headset Hands-Free AG Audio") and select Set as Default Device and Set as Default Communication Device.
4. Repeat this process in the Recording tab for the headset microphone.
5. Disable Power Management for Bluetooth Adapter

Your computer might be turning off power to the Bluetooth adapter to save energy, particularly when shifting to a high-demand application like Teams.

1. Type "Device Manager" into the Windows search bar and open it.
2. Expand the Bluetooth section.
3. Right-click your Bluetooth adapter (often labeled Intel Wireless Bluetooth, etc.) and select Properties.
4. Go to the Power Management tab.
5. Uncheck the box that says "Allow the computer to turn off this device to save power."
6. Click OK and restart your computer.
7. Clear Teams Cache

A corrupted Teams cache can sometimes cause unpredictable behavior when detecting devices.

1. Type settings in the search box, and then select the Settings app from the results.
2. Select Apps > Installed apps and then type Microsoft Teams in the search box.
3. Locate the New Microsoft Teams app from the results, select the More options button (...) on the right, and then select Advanced options.
4. In the Reset section, select Reset.
5. Restart Teams.

4. Ensure Correct Device Selection within Teams

Even if the system default is set, Teams sometimes locks onto the wrong device profile.

1. In Teams, click the three dots next to your Profile picture > Settings > Devices.
2. Under Audio devices, ensure your headset is selected for both Speaker and Microphone.
3. Avoid using the "Default" option in the Teams Devices menu; explicitly select your headset's full name (e.g., "Logi Zone Wireless Headset").
