Hey there, I totally get how frustrating this is—your headphones work perfectly with your phone and desktop, but just won’t show up on your laptop even though its Bluetooth is working fine with other devices. Let’s walk through some targeted fixes to get this sorted:

• Double-check the headphones’ pairing mode
  First, disconnect the Momentum 4 from your phone/desktop (if they’re still connected). Then press and hold the power button on the headphones for around 10 seconds until the indicator light starts flashing rapidly—this puts it into pairing mode. Now try searching for devices on your laptop again; sometimes the headset just needs a fresh trigger to be detected.

• Restart Bluetooth services on your laptop
  Press Win + R to open the Run dialog, type services.msc and hit Enter. Look for Bluetooth Support Service in the list:

  • If it’s stopped, right-click it and select Start.
  • If it’s already running, right-click and choose Restart.
    Once done, refresh your Bluetooth device list and see if the headphones appear.

• Clear old Bluetooth device cache & re-install drivers
  Sometimes leftover pairing data can cause detection issues:

  1. Press Win + X and select Device Manager.
  2. Expand the Bluetooth category, right-click your laptop’s Bluetooth adapter (it might say Intel Bluetooth, Realtek Bluetooth, etc.), and choose Uninstall device.
  3. Check the box that says Delete the driver software for this device, then click OK.
  4. Restart your laptop—Windows will automatically reinstall the Bluetooth driver. Now try pairing the headphones again.

• Toggle Bluetooth/flight mode to refresh the connection
  Right-click the Bluetooth icon in your taskbar, select Turn Bluetooth off, wait 10 seconds, then turn it back on. Alternatively, toggle flight mode on and off via the quick settings panel—this resets the Bluetooth radio and often fixes detection glitches.

• Check for Windows updates
  Outdated system files or drivers can mess with Bluetooth compatibility:

  1. Press Win + I to open Settings, go to Update & Security.
  2. Click Check for updates and install all available Windows updates, including optional driver updates.
  3. Restart your laptop after updates are installed, then try pairing again.

• Factory reset the headphones (last resort)
  If none of the above works, resetting the headphones to factory settings can clear any persistent pairing issues:
  Press and hold the power button + volume down button for about 15 seconds until the indicator light flashes multiple times. Once reset, put the headphones back into pairing mode and let your laptop search for it again.
