[SOLVED] – Logitech G733 Headset Not Working

I was planning to replace my Logitech G733 because of various issues like volume wheel not working, mute button not working, and more. Then I decided to do some research to solve the problems.

In this article I have addressed all possible issues in Logitech G733 and solutions. I hope this helps you.

Let’s begin!

Logitech G733 Volume Wheel Not Working

Logitech G733 has a volume wheel on its left cup to adjust the PC’s sound volume. However, as reported by its users, the Logitech G733 headset volume wheel stopped working suddenly. The volume bar does show up whenever they try to use the wheel, but they can’t adjust the sound.


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 G733 volume wheel problem is reinstalling the website’s newest version of G Hub software.

Logitech G733 Mic not Working

The next problem reported by some G733 users is the mic malfunction. 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.


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 G733 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.

Static Noise in Logitech G733

Some Logitech G733 users report the constant sound buzzing in the right cup of the headset. If they put their hand on the left cup or move their head, the sound goes away for some time but comes back again. The buzzing continues even if all the other electrical devices in the surroundings are turned off to avoid interference.


The buzzing is louder when the volume is higher, or the RGB is enabled on the headset. This noise is even more if the Pink and Blue color is included in the RGB combination.

So, one fix is to turn the RGB OFF. It will remove the static noise in Logitech G733.

Another fix is to force stop the G hub software from the task manager while using the headset. Ending the G hub software from the task manager instantly removes the noise.

Logitech G733 Not Turning On

Logitech G733 stops turning on and charging sometimes. The USB dongle is connected, but the headset itself doesn’t turn on and doesn’t charge.


The solution to this problem is to reset the Logitech G733 headset. There is a small reset hole on the left earmuff. There are two ways to reset the Logitech G733.

  • Use a phone pin or a safety pin to press the reset button couple of seconds safely.
  • Remove the right earmuff by pulling it off and hold down the reset button conveniently. To put back the earmuff, start from the top.

Logitech G733 Sound Not Working

Sometimes the Logitech G733 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 G733 Mute Button Not Working

Another reported problem is that the Logitech G733 mute button stops working occasionally. Users can’t mute or un-mute their headsets even when pressing the mute button.


Ensure that the headset 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 will work instantly.

High Pitch Sound From Logitech G733

Some users experience a high-pitched sound in the left earcup of their Logitech G733. Unfortunately, reinstalling the headset or reinstalling the software didn’t help resolve the issue.


The LEDs inside the headset probably cause the high pitch sound or buzzing issue. If the LEDs are cheap, have poor circuit design, or have grounding issues with the controller, it causes a high-pitched sound.

The first fix is to change the LED mode from ‘breath’ to ‘fixed’ or turn the LEDs off. Another fix is to increase the brightness of the headset from G Hub software. Unfortunately, it causes more power supply to LEDs that in turn breaks out the vibration causing a high-pitched sound.

Yet another fix is to keep the charging cable plugged in a while using the headset. Again, however, it can affect the battery life in the long run.

Logitech G733 Not Showing Up in G Hub

The problem is that sometimes after a G Hub software update or for some other reasons, the Logitech G733 stops showing up in G hub. Unfortunately, that means the G733 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 G733 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 G733 from the device manager
  • Install the updated version of G Hub from the website.
  • Restart your PC and reconnect the headset.

Logitech G733 Gets Stuck on Setting Up

Reportedly, the Logitech G733 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 G733 USB Receiver Not Working

According to its users, the Logitech G733 Lightspeed receiver stopped working when they had plugged the receiver back into the USB port. None of following worked

  • plugging the receiver in different ports,
  • resetting the headset, or
  • unplugging and plugging 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 get the receiver working again.

Yet another solution is to use a G933 receiver with the G733 headset. Just reset the G933 receiver until it starts flashing rapidly. Then, pair it with the headset to begin using. Please note that some options can be limited, but it will work fine otherwise.

Logitech G733 Keeps Disconnecting

The Logitech G733 keeps disconnecting and reconnecting for some of its users. It happens randomly and can be very annoying.


Ensure that the headset is closer to the USB dongle and the dongle is plugged into the front port. 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.
