If Teams does not recognize your headset, Zoom cannot find your microphone, or your Bluetooth microphone is not working in Windows, the following troubleshooting steps can help you resolve the issue.
| Brief explanation: If your Teufel Bluetooth headphones’ microphone does not work in Teams, Zoom, or other calling applications, Windows may have selected the wrong Bluetooth profile. Check the audio settings in Windows and the application, and make sure your headphones are selected as both the input and output device. |
Setting Up Bluetooth Headphones for Teams, Zoom, and Other Calling Apps
If your Teufel Bluetooth headphones are connected to Windows but the microphone does not work in Teams, Zoom, or other calling apps, check the audio settings in Windows and the app you are using. The issue is often caused by the wrong Bluetooth profile being selected.
Windows 11
- Open Settings.
- Select System > Sound.
- Scroll to the Output section and select your Teufel headphones.
- Scroll to the Input section and check if the microphone of your Teufel headphones is selected.
- Restart Microsoft Teams, Zoom, or the calling application you are using.
- Open the audio settings in the application and select your headphones as both the speaker and microphone.
Windows 10
- Open Settings > System > Sound.
- Under Choose your output device, select your Teufel headphones.
- Under Choose your input device, select your headphones’ microphone.
- Restart the calling application.
- Check the audio settings within the application.
Additional Tip for Windows 11 & 10
If your microphone is still muted after following the steps above, check under Settings > Privacy & Security > Microphone that the options “Allow apps to access your microphone” and “Allow desktop apps to access your microphone” are enabled. Windows privacy settings can sometimes prevent Teams or Zoom from accessing your microphone.
Microphone Still Not Working?
- Disconnect your headphones from Bluetooth.
- Restart the headphones.
- Reconnect the headphones to Windows.
- In Teams, Zoom, or another application, check that the headset/hands-free version of your headphones is selected.
- Make a test call in Microsoft Teams or Zoom and check whether your microphone is recognized and your voice is transmitted.
Background: Why Does This Problem Occur?
Bluetooth headphones can operate under Windows using different Bluetooth profiles:
- Option "Stereo A2DP" (Advanced Audio Distribution Profile): This profile is used exclusively for listening to music, videos, and movies in stereo. Making calls is not possible with this profile.
- Option "HFP" (Hands-Free Profile): This profile is used for playing the caller’s voice and transmitting your microphone audio. Making calls is possible with this profile.
Note: Many conferencing apps automatically detect the difference between music playback and calls and switch from the stereo option to the hands-free option when you make or receive a call. However, with some models and depending on your settings, you may need to select the profiles manually. This can usually be done in the settings of the respective chat application as well as in Windows.
Frequently Asked Questions
Why can I hear the other person but not speak?
In this case, Windows is often using the stereo profile (A2DP). This profile does not support microphone input. Instead, select the headset or hands-free version of your headphones.
Why are my Teufel headphones shown twice?
Windows often creates two audio profiles:
- Stereo (for music playback)
- Hands-Free or Headset (for calls)
For Teams, Zoom, and other conferencing applications, the headset version must be selected.
Why does the audio quality sound worse during a call?
During a call, Bluetooth often automatically switches to the hands-free profile. This activates the microphone but reduces the available bandwidth for audio playback.
