Bluetooth Headset Troubleshooting

Step 1 – Remove and Pair the Headset Again

  1. Go to Settings > Bluetooth & devices.

  2. Find your Logitech headset and select Remove device.

  3. Restart the PC.

  4. Put the headset into Bluetooth pairing mode.

  5. Pair the headset with Windows again.

  6. Check whether the issue is resolved.

If the issue continues, proceed to Step 2.

Step 2 – Reinstall the Bluetooth Driver

We recommend trying the Bluetooth driver provided by your PC manufacturer first.

Download the Bluetooth Driver

  1. Go to your PC manufacturer's support website, such as Dell, HP, or Lenovo.

  2. Search for your exact PC model or enter the Service Tag / Serial Number.

  3. Find and download the latest Bluetooth driver for your PC and Windows version.

  4. If your PC uses an Intel Bluetooth adapter and the issue still occurs after reinstalling the manufacturer's driver, you can also try the latest Bluetooth driver directly from Intel's support website.

Remove the Existing Bluetooth Driver

  1. Right-click the Start button and select Device Manager.

  2. Expand Bluetooth.

  3. Find the Bluetooth adapter. Common examples include:

    • Intel(R) Wireless Bluetooth(R)

    • Realtek Bluetooth Adapter

    • MediaTek Bluetooth Adapter

  4. Right-click the Bluetooth adapter and select Uninstall device.

  5. If available, select Attempt to remove the driver for this device.

  6. Restart the PC.

Reinstall the Bluetooth Driver

  1. Install the Bluetooth driver downloaded from your PC manufacturer's support website.

  2. Restart the PC again.

  3. Pair the Logitech headset again and check whether the issue is resolved.

  4. If the issue persists and the PC uses an Intel Bluetooth adapter, repeat the process using the latest Bluetooth driver downloaded directly from Intel.

  5. Pair the headset again and verify the Bluetooth audio and microphone.

If the headset can connect successfully but you still experience audio or microphone issues, proceed to Step 3.

Step 3 – Reinstall the Audio / Intel Smart Sound Technology Driver

If the headset is connected but you experience audio or microphone issues, reinstalling the PC manufacturer's Audio / Intel Smart Sound Technology (ISST/SST) driver may help.

Step 3.1 – Reinstall the Audio Driver

  1. Go to your PC manufacturer's support website.

  2. Search for your exact PC model or enter the Service Tag / Serial Number.

  3. Go to the Audio driver section.

  4. Download and install the latest available Audio driver provided by the PC manufacturer, such as Realtek Audio or another applicable audio driver.

  5. If the PC manufacturer also provides an Intel Smart Sound Technology (ISST/SST) driver, download and install it as well.

  6. Restart the PC.

  7. Reconnect the Logitech headset.

  8. Check the speaker and microphone again.

Note: Some PC manufacturers do not provide a separate Intel Smart Sound Technology driver on their support website. In this case, install the available Audio driver first, then continue to Step 3.1 and use Windows Update to check for an updated Intel SST driver.

Step 3.1 – Check Windows Update for Driver Updates

  1. Go to Settings > Windows Update.

  2. Select Check for updates.

  3. Install all available Windows updates.

  4. Go to Advanced options > Optional updates > Driver updates, if available.

  5. Check whether an updated Intel Smart Sound Technology driver is available.

  6. Install the available driver updates.

  7. Restart the PC.

  8. Reconnect the Logitech headset and test the speaker and microphone again.

If Windows Update provides a newer Intel Smart Sound Technology driver, complete the Windows Update process first and verify whether the issue is resolved.

If the issue still occurs and Windows Update does not provide a newer Intel SST driver, continue with the driver rollback procedure below.

Step 3.2 – Try an Older Intel Smart Sound Technology Driver

If the issue persists with the currently installed Intel SST driver, you can try switching to an older compatible driver version already available on the PC.

A. Check Intel SST Devices Under Sound, Video and Game Controllers

  1. Open Device Manager.

  2. Expand Sound, video and game controllers.

  3. Look for devices whose names begin with Intel Smart Sound Technology.

Depending on the PC model and Windows configuration, you may see devices such as:

  • Intel Smart Sound Technology for Bluetooth Audio

  • Intel Smart Sound Technology for Bluetooth LE Audio

  • Intel Smart Sound Technology for Digital Microphones

  • Other Intel Smart Sound Technology audio devices

  1. Right-click an Intel Smart Sound Technology device and select Update driver.

  2. Select Browse my computer for drivers.

  3. Select Let me pick from a list of available drivers on my computer.

  4. Review the available compatible driver versions.

If multiple driver versions are available and the newest version is currently being used, select an older compatible version.

  1. Select Next and complete the driver installation.

  2. Repeat the same procedure for the applicable Intel Smart Sound Technology devices in this section.

When possible, use older drivers from the same driver generation or package to keep the Intel SST components consistent.

B. Check Intel SST Devices Under System Devices

  1. In Device Manager, expand System devices.

  2. Look for devices containing Intel Smart Sound Technology in their names.

Depending on the PC model and platform, you may see devices such as:

  • Intel Smart Sound Technology OED

  • Intel Smart Sound Technology BUS

  • Intel Smart Sound Technology Detection Verification

  • Other Intel Smart Sound Technology system components

  1. Right-click an applicable Intel Smart Sound Technology device and select Update driver.

  2. Select Browse my computer for drivers.

  3. Select Let me pick from a list of available drivers on my computer.

  4. Review the available compatible driver versions.

  5. If an older compatible version is available, select it and click Next.

  6. Repeat the procedure for the applicable Intel Smart Sound Technology devices.

After switching the applicable Intel SST devices to older compatible driver versions:

  1. Restart the PC.

  2. Reconnect the Logitech headset.

  3. Test the Bluetooth speaker and microphone again.

Important: Only select drivers that Windows lists as compatible with the device. Do not manually remove Intel SST devices or install unrelated driver packages. If multiple Intel SST components are being changed, use compatible versions from the same driver package or generation whenever possible.
