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.
| Brief explanation: If your Teufel Bluetooth headphones do not transmit a microphone signal in Teams, Zoom, or other telephony applications, Windows often uses the stereo profile (A2DP) instead of the headset profile (Hands-Free/HFP). Check the audio settings in Windows and the respective application and select the headphones as both microphone and speaker. |
Setting Up Teufel Bluetooth Headphones for Teams, Zoom, and Other Telephony Apps
If your Teufel Bluetooth headphones are connected to Windows but the microphone does not work in Microsoft Teams, Zoom, or other telephony applications, check the audio settings in Windows and the respective application. Often the wrong Bluetooth profile is 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.
- Then restart Microsoft Teams, Zoom, or the telephony application you are using.
- Open the audio settings of the application and also select your Teufel headphones as both speaker and microphone there.
Windows 10
- Open Settings > System > Sound.
- Under Choose your output device, select your Teufel headphones.
- Under Choose your input device, select the microphone of your Teufel headphones.
- Restart the telephony application.
- Check the audio settings within the application.
Additional Tip for Windows 11 & 10
If your microphone remains muted despite the above steps, check under Settings > Privacy & Security > Microphone whether the options “Allow apps to access your microphone” and “Allow desktop apps to access your microphone” are enabled. Sometimes Windows privacy settings completely block access for Teams or Zoom.
Microphone Still Not Working?
- Disconnect the Bluetooth connection to the headphones.
- Restart the headphones.
- Reconnect the headphones to Windows.
- Check in Teams, Zoom, or another application whether the headset/hands-free version of the device is selected.
- Make a test call in Microsoft Teams or Zoom and check if your microphone is recognized and an audio signal 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 protocol is used exclusively for listening to music, video, and movie sound in stereo. Telephony is not possible with this profile.
- Option "HFP" (Hands-Free Profile): This protocol is used for playing the caller’s voice and transmitting the microphone signal. Telephony is possible here.
Note: Many conferencing apps automatically detect the difference between music and calls and switch accordingly from the stereo option to the hands-free option as soon as you make or receive a call. However, with some models, depending on user settings, the profiles must be selected manually. This can usually be done in the settings of the respective chat software as well as in Windows.
Frequently Asked Questions
Why can I hear the other person but cannot speak?
In this case, Windows often uses the stereo profile (A2DP). This profile does not support the microphone function. Instead, select the headset or hands-free version of your Teufel headphones.
Why is my Teufel headphone shown twice?
Windows often creates two audio profiles:
- Stereo (for music)
- Hands-Free or Headset (for telephony)
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 bandwidth available for audio playback.
