How to fix JBL Quantum 100 Microphone not working?

Check your connections:

For JBL Quantum 100, you can use a USB switcher. If you use the switcher, ensure that the mute switch hasn’t been activated. There is a chance that the problem could be with one of the USB ports. Try connecting the switcher to another USB port. If that does not work, you can also use the 3.5mm audio jack connection. Just make sure that the connectors are all connected properly.

If all your connections are well set up, move on to the next solution mentioned here.

Turn on Microphone:

Windows 10 come with permission requirements for accessing the microphone of a headset. If the microphone on your JBL Quantum 100 headphone is not permitted, it won’t be able to provide any input to the computer. So to give access to the microphone on your headset, follow the steps mentioned below.

  • Press Windows Key + I and then select Privacy from the list of options that show up.
  • Click on the Microphone option under permissions in the left pane inside the privacy menu.
  • On the right pane, look for the option “Allow Access To The Microphone On This Device.” Under that option, you will see a change button. Click on it and make sure that the toggle is on.
  • Now, look for the other option, “Allow Apps To Access Your Microphone,” and make sure it is also turned on.

Now close the settings page and try using the microphone on your headphones again. If it still does not work properly, try the next solution mentioned below.

Check your sound settings:

The JBL Quantum 100 headphones microphone might not work because it is not set as the default audio device on your computer. To change that, you need to get into the sound settings of your Windows computer.

  • Press Windows key + R to open up the Run dialog box.
  • Enter “control” in the Run dialog box and press Enter.
  • Select Large icons from the View by drop-down menu at the top.
  • Click on Sound.
  • Select the recording tab.
  • Right-click on any empty place inside the device list and check the box for “Show Disabled Devices.”
  • Right-click on your headset microphone and then select Enable.
  • Then right-click on it again and select “Set as Default Device.”

Now try using the microphone on your headset. Try the next solution if it still does not work properly.

Update the drivers:

Audio drivers need to be updated on Windows systems from time to time. Especially to keep the JBL Quantum 100 headphones running without any problems, you will need the latest audio drivers on your computer.

There are three ways to update or install audio drivers on a Windows computer. Firstly, you can visit your computer manufacturer’s website, and on their support or download page, you will find the setup file for the audio drivers. You need to download the setup file from that site and then install the drivers onto your computer just like any other program.

Secondly, you can let Windows look for the drivers themselves and automatically install them on your computer.

  • Press Windows key + X and then choose Device Manager from the list of options.
  • Double-click on audio inputs and outputs and then right-click on “Microphone.”
  • Select Update Driver.
  • Then follow the on-screen instructions to let your computer scan the internet for the latest drivers.
  • If it finds any new drivers, Windows will automatically install them on your computer.

The last method for updating drivers is to use a third-party driver utility tool. Several tools can scan your computer for any missing or outdated drivers. If the audio driver on your computer is out of date, it will show up in one of these tools. Then you need to click on one button, and the latest drivers will be installed on your computer. These driver utility tools charge a bit for their service, but it is well worth it since you need to worry about any drivers on your computer again.

Try the next solution if updating the audio drivers does not solve your microphone issue.

Uninstall third-party audio tools:

Many of us use third-party equalizer audio tools on our computers to enhance the audio experience. By default, we get different audio settings and profiles when installing audio drivers. But some users like to tweak their audio experience, and in search of that, they use specific third-party audio tools as per their needs. These third-party audio tools could be the cause behind your problem, though.

The JBL Quantum 100 headphones might not be compatible with the third-party audio tool you are using on your computer. In that case, the microphone won’t work no matter what you try with the application installed on your computer. The only solution is to entirely uninstall that third-party audio from your computer.

Try the next solution if uninstalling the third-party audio tool did not solve your problem with the microphone.

Run Audio troubleshooter:

Windows has a troubleshooter utility tool that can scan the computer for any known issues and try to fix them for the user. If the troubleshooter can’t fix the issue, it will at least display information to the user about what is wrong with the Windows system. So for the microphone issue with the JBL Quantum 100.

  • Press Windows Key + I and then select Update & Security from the list of options.
  • Then click on the Troubleshooting tab in the left pane.
  • Click on Additional troubleshooters.
  • In the next menu, click on the “Speech” option. That will initiate the speech troubleshooter for you. Make sure to keep the headphones connected when you are doing this.
  • Let the troubleshooter run the scan and try the fixes for the problems that show up.

After the troubleshooter fixes your problem, you should be able to use the microphone.

If none of the solutions mentioned above worked for you, then there is a possibility that the problem is with the headphone themselves. It could be a hardware defect affecting the microphone of your JBL Quantum 100 headphones. In that case, you can go to a repair center or get a replacement pair for it.
