Logi Zone Wireless 2 ES for Business audio & mic not working over Bluetooth connection

Hi James Flaherty,

Since the microphone test in Windows Sound settings shows 0% input when the headset is connected via Bluetooth (even outside of Teams), this may indicate that Windows is not fully loading the Bluetooth communication profile needed for microphone use.

Please try the following:

1. Go to Control Panel > Devices and Printers
2. Right‑click Logi Zone Wireless 2 and select Properties
3. Open the Services tab
4. Uncheck Handsfree Telephony and select Apply
5. Wait a few seconds, then re‑check it and select Apply again
6. Restart the device and test the microphone in Windows Sound settings

If the issue continues, I recommend checking with your device manufacturer (HP) for any additional Bluetooth or audio driver updates for your laptop model.

In the meantime, using the included USB receiver may provide the most stable experience for both audio and microphone functionality.

Please let me know how it goes.

Since the headset works with the dongle but not over Bluetooth, focus on Windows Bluetooth audio support and drivers.

1. Confirm Bluetooth audio profile support (A2DP)
   • The Bluetooth device must support the A2DP protocol for higher-quality audio streaming and proper audio/mic behavior.
   • Check the documentation or manufacturer’s website for Logi Zone Wireless 2 ES for Business and confirm that Bluetooth mode supports A2DP and hands-free audio on Windows.
2. Update Bluetooth drivers from Device Manager
   • Select Start > Device Manager.
   • Expand Bluetooth and select the Bluetooth adapter (may include the word “radio”).
   • Right-click it and select Update driver > Search automatically for updated driver software.
   • Complete the wizard, then restart the PC (Start > Power > Restart) and test the headset again over Bluetooth.
3. Check Windows Update
   • Select Start > Settings > Windows Update.
   • Select Check for updates and install all available updates, including optional driver updates.
   • Restart and test the Bluetooth connection again.
4. Remove and re-pair the Bluetooth headset
   • Press Windows logo key + I to open Settings.
   • Go to Bluetooth & devices.
   • In Devices, locate the Logi Zone Wireless 2 ES under the relevant category (for example, Audio).
   • Select More options for the device and choose Remove device, then confirm.
   • Pair the headset again following the manufacturer’s instructions and test mic and audio.
5. If audio devices disappear or show as “no audio device”
   • Open Device Manager and verify that audio drivers are installed and working.
   • If needed, reinstall or update the audio driver from the PC manufacturer’s site.
   • Optionally run the Playing Audio troubleshooter from Settings > System > Troubleshoot > Other troubleshooters.
6. If others can’t hear the user in apps
   • Ensure the Bluetooth headset is paired and connected as a Bluetooth device.
   • Set it as the default recording device:
     • Start > Settings > System > Sound.
     • Under Input, choose the Logi Zone Wireless 2 ES.
     • Use Start test under Microphone test to verify that Windows detects input.

If, after driver updates, Windows updates, and re-pairing, the mic still shows 0% input only in Bluetooth mode, this typically indicates a limitation or compatibility issue with the Bluetooth profile implementation on that PC and the headset. In that case, continue using the dongle for full audio and mic functionality and consult the headset manufacturer’s guidance for Bluetooth support on Windows.
