Since the microphone works correctly with your phone, the headset hardware is likely functioning properly.
In addition to the steps already suggested, please try the following:
- If you're using the included Jabra Link 380 USB dongle, connect through the dongle instead of standard Bluetooth. Jabra recommends the dongle for full headset and microphone functionality.
- Install Jabra Direct and check for firmware updates for both the headset and the Jabra Link adapter. Firmware updates have addressed microphone-related issues on Evolve2 devices.
- Open Device Manager, expand Sound, video and game controllers, uninstall the Jabra audio device, then select Scan for hardware changes or restart the PC. Some users have reported that Windows re-detecting the device restored microphone functionality.
- If the headset is connected via Bluetooth, try removing it from Settings > Bluetooth & devices, then pair it again. Re-pairing has resolved microphone detection issues for some Windows 11 users.
If the Jabra microphone still does not appear under Settings > System > Sound > Input, please let us know whether you are using Bluetooth directly or the Jabra Link USB adapter, and whether the headset appears in Device Manager. That will help narrow down the cause.
