Logitech G735 Not Turning On

If the G735 doesn’t work at all, it’s possible that the battery is completely discharged. To check the level, short press the power button on the left ear cup.

If the LED doesn’t light up at all, charge the headset using the USB cable provided. The power light will illuminate green and pulse while charging.

Logitech G735 Volume Wheel Not Working

Logitech G735 has a volume wheel on its left cup to adjust the PC’s sound volume. However, sometimes the Logitech G735 headset volume wheel stops working suddenly. The volume bar does show up when attempting to use the wheel, but the sound level cannot be adjusted.

This headset supports Lightspeed technology and comes with a USB receiver. So the first solution is to connect this USB receiver to another PC port.

Another solution to the Logitech G735 volume wheel problem is re-installing the website’s newest version of G Hub software.

Logitech G735 Mic not Working

The next problem reported by some G735 users is a malfunctioning microphone. This issue exists even in the new, straight-out-of-the-box headsets too. The G hub software audio bar doesn’t detect the user’s audio.


As a first step, make sure that the detachable mic is connected properly to the headset.

If this didn’t solve the problem, the solution to this problem is to go into Windows sound settings by right-clicking the volume icon and selecting ‘Recording devices.’ Then highlight the G735 Mic, disable, and re-enable it. After re-enabling, ensure that this Mic is chosen as the default device.

Also, test the Mic to confirm that the problem exists in Mic and not a particular App you are currently using. To test

  • Go to the sound settings
  • Highlight the Headset Mic and click Configure
  • Click on Setup Mic and then select Headset Mic
  • Click Next and read the sample phrase on the Mic to test the sound input.

Logitech G735 Sound Not Working

Sometimes the Logitech G735 sound stops working. Even when the Windows settings say that the input and output are working, the users can’t hear anything from the headset.


The solution to this problem is:

  • Go to Windows setting
  • Ensure the volume slider is un-muted, and the headset volume is 20%
  • Next, ensure that the volume mixer for all the apps is 100
  • To do so, click on the volume icon and select Volume Mixer
  • Also, ensure that your headset is chosen as the default device in sound settings

As these solutions worked for many, you can also unplug and plug your headsets back in or change the USB port.

Logitech G735 Mute Button Not Working

Another reported problem is that the Logitech G735 mute button stops working occasionally. Users can’t mute or un-mute their headsets even when pressing the mute toggle button.


Ensure that the Lightspeed USB dongle is connected directly to the motherboard through the USB port and not any hub. Also, perform the device firmware update. To check if the update is available or not, launch your G Hub App, select the headset and then go to settings. An update button will appear under the firmware version if the update is available.

Another solution is to remap the mute button to ‘mute audio output.’ This solution should work instantly.

Logitech G735 Mixer Does Not Work

One of the unique features of the G735 relative to the G733 is the audio mixer. The G735 can be connected to multiple sources over the different connectivity methods (3.5mm AUX, Bluetooth or Lightspeed).

Note that for audio mixing to work, the headset must be connected to both intended sources. Instructions are provided on page 7 and 8 of the user guide. Note that a max of two sources can be mixed, not three.

If you are having issues with Lightspeed, ensure first that the dongle is plugged in and works. This should be verified independent of other connections. Similarly with Bluetooth and AUX. If either connection is not working individually, you will not be able to mix it with another.

Logitech G735 Not Showing Up in G Hub

The problem is that sometimes after a G Hub software update or for some other reasons, the Logitech G735 stops showing up in G hub. Unfortunately, that means the G735 picture is greyed and can’t be selected. The headset works fine, but the users can remap or edit any settings of the headset.


First, ensure from the Windows sound settings that the G735 is selected as a default headset. If the headset is already set to default, try the following steps.

  • Uninstall the G hub software and open the search window by pressing Win+R
  • Type %AppData% and delete the Logitech folder from the AppData
  • Disconnect and uninstall Logitech G735 from the device manager
  • Install the updated version of G Hub from the website.
  • Restart your PC and reconnect the headset.

Logitech G735 Gets Stuck on Setting Up

Reportedly, the Logitech G735 gets stuck during setup on G Hub software. When stuck, the users can’t edit the equalizer or mic settings, nor can they check the battery percentage. Unfortunately, uninstalling and reinstalling the software doesn’t fix the issue either.


Try reinstalling the G Hub software by following the steps mentioned:

  • Uninstall the G Hub software
  • Ensure there is no G Hub component running in the task manager.
  • Delete the LGHUB folder from Program Files and Program data in the C drive.
  • Delete LGHUB folder from AppData\local and AppData\roaming from C:\users/<username>
  • Press Windows Key, then type Regedit, Click Registry Editor
  • Delete the registry key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{521c89be-637f-4274-a840-baaf7460c2b2}
  • Restart the PC and install G Hub software again
  • Ensure that the microphone is enabled in sound settings even if you are not using it.

Logitech G735 USB Receiver Not Working

Try the following:

  • Plug the Lightspeed receiver dongle into a different USB port,
  • Reset the headset, or
  • Unplug and plug the receiver back in


There is a factory reset button in the small hole on the USB receiver right below the logo. Press that reset button for 5-10 seconds. It will reset the dongle and this might get the receiver working again.

Yet another solution is to use Bluetooth. The G735 supports both Lightspeed and Bluetooth.

Logitech G735 Keeps Disconnecting

The Logitech G735 keeps cutting out at random. An unreliable connection can be very frustrating


At least one user has reported that the wireless range of the G735 is quite small (8 feet) relative to other wireless connections. Bring the headset closer to the USB dongle and plug the dongle into the USB port at the front of the PC. Sometimes if the dongle is plugged into a USB port at the back of the PC, the computer case interferes with the RF signals, and the headset will disconnect.

Another solution is to remove all possible sources of RF interference like Wi-Fi access points or routers that might be on your desk for instance.

As an alternative, also try connecting the G735 to your PC or laptop over Bluetooth and see if that improves the reliability of the wireless connection.
