Jabra is arguably the most reputable brand when it comes to professional headsets for offices. Evolve 75 is one of Jabra’s most advanced and most popular headset models.
Jabra Evolve 75 supports wireless and wired connections. It can be connected to two Bluetooth devices simultaneously, it’s easy to set up and use, the microphone quality is fantastic, and its noise-canceling abilities are above average.
Most importantly, Jabra Evolve 75 is compatible with numerous UC platforms and is certified for Microsoft Teams, Zoom, Skype for Business, etc.
Up until recently, I was perfectly happy with my Jabra Evolve 75. The headset worked flawlessly right out of the box, and I didn’t have to adjust anything. The sound was crystal clear, and the battery was great. The battery life deteriorated a little over time, but that’s perfectly normal.
After almost two years of active use with no issues, I recently experienced a problem I didn’t see coming. My Jabra Evolve 75 microphone suddenly stopped working. At first, I thought it was a software issue, but it didn’t make any sense. Everything worked fine for 2 years, and I didn’t change anything on my PC.
So, after checking my PC settings, I went through forum posts and found out that Jabra Evolve 75 headset has a design flaw (or is it a planned obsolescence).
The wire that connects the microphone to the PCB goes through the PCB, and when you move the microphone up and down, the wire rubs against the PCB and gets damaged (over time) due to friction. Replacing the wire and slightly altering the design fixed my problem.
I’m not implying that you are dealing with the same issue. If you’re having problems with a brand-new headset or trying to connect the headset to a new device, the problem is probably software or firmware-related.
But if it’s an older headset that worked fine for quite some time, the chances are your microphone stopped working because of that tiny wire that connects the microphone to the PCB.
In this post, I will guide you through the whole troubleshooting process. I will discuss various reasons that could cause your Jabra Evolve 75 microphone to stop working and offer you several fixes that might bring your mic back to life.
- If you’re having problems with a new headset or when trying to connect a relatively new and perfectly functional headset to another device, you are probably dealing with some kind of software or firmware issue. In this case, you need to go through the settings on your PC.
- There are several settings you need to check and adjust to potentially solve the microphone issue.
- Some of the potential fixes include restarting all equipment, updating Windows, resetting and updating your headset, allowing critical apps (Microsoft Teams, Skype, Zoom) to access the microphone, unmuting your microphone in Windows/macOS settings, making your microphone the default recording device, updating or reinstalling audio drivers.
- If you are having problems with an older headset (older than 1.5 years) that used to work fine until recently, the wiring inside the headset is probably damaged. To be more specific, there’s a tiny wire that connects the microphone to the PCB. This wire suffers friction as you move the mic up and down, and inevitably gets damaged over time.

Why Is My Jabra Evolve 75 Microphone Not Working?
Let’s discuss a few scenarios.
If the headset is brand-new and you’re trying to connect it for the first time, hardware issues (like broken headset or damaged wiring) are the least possible cause of the problem. It’s far more likely that you have to adjust some settings on your PC or in-app settings.
If your Jabra Evolve 75 is relatively new and fully functional when connected to one device, but the microphone is not working when connected to another device, the problem is either software-related or firmware-related. So, you need to check the settings on your PC and, if all the settings are correct, you could try resetting your headset or updating its firmware.
As the headset gets older, hardware issues become more probable. You still can’t rule out software or firmware-related issues, but if the microphone worked fine one day and then suddenly died or became unusable with lots of static noise, it’s most probably a hardware issue.
Ways to Fix Jabra Evolve 75 Microphone Not Working
Move the Boom Arm Up and Down
The Jabra Evolve 75 headset doesn’t have a dedicated mute button. The boom arm functions as the mute button – when you move it up, the microphone is muted. When you move it down, it’s unmuted. Also, when there’s an incoming call, moving the boom arm down will automatically answer that call.
Due to a firmware glitch, the mic might stay muted when the boom arm is down. Try moving it all the way up and down again. Move the arm up and down a few times, but don’t push it too much – you don’t want to damage your mic.
This is the most basic troubleshooting step. It proved to be very efficient in fixing minor issues with all kinds of electronics, so let’s try it.
Turn off your headset, remove the USB dongle, then restart your PC. When the PC turns on, connect the dongle and turn on your headset. Try connecting it again.
Try Forgetting and Pairing Your Headset Afresh
If you used Bluetooth to connect the headset to your phone or PC, you could also try forgetting the headset from your device, restarting your equipment, and then pairing the headset afresh.
To put the headset in pairing mode, push the power button towards the Bluetooth logo until the LED starts flashing blue.
Once the headset is in pairing mode, go to your device’s Bluetooth settings, find your headset, and connect.

Reset Your Jabra Evolve 75
Headset firmware might develop bugs over time. Those bugs might be preventing your microphone from working properly. Resetting the headset might erase the firmware bugs and potentially fix the issue.
The procedure is quick and straightforward. Make sure the headset is turned on. Locate the VOL UP and ANSWER buttons on the right cup. Press them simultaneously for about 5 seconds. Release them when the LED starts flashing green rapidly.

Update Your Jabra Evolve 75
The headset firmware is not perfect. It may have some hidden bugs the manufacturer didn’t discover earlier. To fix those bugs and introduce new features, the manufacturer releases firmware updates.
If one of those hidden bugs is causing your microphone issue, updating it might fix the microphone.
To update your Jabra Evolve 75, you need to download the latest version of the Jabra Direct app. The app is available for Windows and macOS.
Once you open the app, there will be a notification in the Device tab if there’s an update available for your headset and USB dongle.
If you don’t see the notification, go to the Updates tab. Click on Check for Updates.
If there’s an update available, click Update and select your language.
After the update is finished, you will see a popup message. Click OK, and check your microphone. If it’s still not working, let’s check some settings on your PC.

Adjust Your PC Settings (Windows/macOS)
If the problem is not in your headset’s firmware, there might be something wrong with your PC’s settings.
macOS computers are easier to troubleshoot since you don’t have so many settings that need to be adjusted. In general, macOS is easier to troubleshoot. Besides trying all the basic troubleshooting steps (restart everything, try using a different USB port for the Jabra USB dongle), you have two more things to check – Sound Settings and Privacy and Security Settings.
Troubleshooting a Faulty Microphone on a macOS Computer
PCs running on Windows are a bit trickier to troubleshoot since you have to check a few more settings.
So, let’s start troubleshooting.
Allow Apps to Access Jabra Evolve 75 Microphone
Every app you want to use with your microphone has to be “whitelisted” in your PC’s settings.
In Windows, go to Settings – Privacy & Security – Microphone.
Enable microphone access, and then go through the list of apps.
If your Jabra Evolve 75 microphone is not working when using a specific app, check whether that app is whitelisted. For example, if you don’t give permission to Skype, your microphone will not work when using Skype.
On macOS computers, go to System Preferences – Privacy & Security – Microphone. You will see a list of apps that can use your headset microphone. Allow access to all the apps you want to use for communication.
Giving App Permissions for Microphone Access in macOS
Set Jabra Evolve 75 Microphone as the Default Device
On Windows devices, go to the Control Panel. Then, select Hardware & Sound. Finally, click on Sound.
Set your headset as the default device in the Playback Tab. Set your Jabra Evolve 75 microphone as the default device in the Recording Tab.
The same applies to macOS computers. Go to System Preferences – Sound. Check the Input and Output Tabs. Select your headset as the default output device and your microphone as the default input device.
Unmute Jabra Evolve 75 Microphone in Sound Settings
While setting up your Jabra Evolve 75 microphone as the default device, you may also want to confirm that your mic is not muted and the mic volume is set to an acceptable level.
After selecting your microphone as the default device in the Control Panel – Hardware and Sound – Sound, go to the Recording Tab. Right-click on your headset’s microphone and select Properties.
Under the General tab at the bottom, select Use This Device (enable).
Then, go to the Levels Tab. If your mic is muted, unmute it. Set the volume level at an acceptable level.
On your MacBook, go to System Preferences – Sound – Input. Set your microphone’s volume level and unmute it if it’s muted.
Update Audio Drivers
This fix applies only to Windows devices. An outdated driver can cause all kinds of audio-related issues, so let’s make sure they are up to date. You should check all the drivers related to your headset and microphone.
Go to Device Manager. You need to check all the audio drivers under Audio Inputs and Outputs, as well as drivers under Sound, Video, and Game Controllers.
After updating the drivers, restart your PC and try connecting your headset. Check if the microphone is working.
Uninstall and Reinstall all Related Drivers
If only one of your audio drivers is corrupt or damaged, you will experience audio issues. The issues might affect your microphone functionality.
Uninstalling and reinstalling corrupt drivers should fix the problem. If you don’t know which driver is causing the issue, uninstall all drivers under Audio Inputs and Outputs and audio-related drivers under Sound, Video, and Game Controllers.
After restarting your PC, the drivers will be reinstalled automatically.
Update your Windows
I am not a fan of Windows updates, and I’m pretty sure no one is. But you have to do it sometimes. If you’re one of those people who block Windows updates right after installing the OS, consider unblocking them and checking for updates. In the process, the microphone problem might go away. I mean, the chances are slim, but it’s still possible.
Uninstall and Reinstall Jabra Direct
Jabra Direct allows you to keep your headset updated and personalize it. However, Jabra Direct could also be the source of your problem. If the app can’t communicate with the headset or if some in-app settings are misconfigured, the app might affect your microphone performance. Try uninstalling and reinstalling the app.
Check the Settings in Your Microsoft Teams and Other Apps
Besides your Windows/macOS computer and Jabra Direct, you can also mute the microphone and adjust the microphone volume in apps that you use for communication (like Microsoft Teams, Skype, and Zoom). So, let’s check the settings in those apps.
In Teams, click on your profile and go to Settings.
Then, select the Devices Tab. Select your Jabra Evolve 75 as the default audio device. Also, set your headset earphones as the default speaker, and your headset mic as your default mic. If you don’t select your microphone, you won’t be able to use it, and people won’t hear you.
The home page also gives you the option to mute the microphone and adjust the mic volume. The microphone needs to be unmuted.
In the Skype settings, under Audio & Video, select your headset’s microphone as your default communication device. You could also try disabling the option Automatically Adjust Audio Settings.
When on a Zoom call, click on the microphone icon in the bottom-left corner to unmute the mic.
If that doesn’t help, check if your headset’s microphone is selected as the default device in Audio Settings. Adjust the microphone volume to a suitable level and disable the option Automatically adjust the volume.
Furthermore, if selecting the right microphone doesn’t help, go to Advanced Audio Settings and disable options: Suppress Persistent Background Noise and Suppress Intermittent Background Noise.
Microphone Not Working On Zoom – Troubleshooting Tips
Your Microphone is Damaged/Broken
If none of the software tweaks helped, you’re probably dealing with a damaged or dead microphone.
As explained earlier, there’s a design flaw in Jabra Evolve 75. A tiny wire that connects your headset’s microphone to the PCB inside the right earcup goes through the PCB. As you move the mic up and down, the wire rubs against the PCB, and it gets damaged over time due to friction. So, the only thing that is damaged is that tiny wire. Your mic is perfectly fine, but the wiring needs fixing.
If your headset is under warranty, the best thing you can do after checking the settings and trying to reset/update the headset is to contact Jabra support and ask for help.
Since the problem with the microphone wiring is well-known, someone from Jabra support will either ask you to send the headset for repair or send you a new headset.
Fixing Broken Jabra Evolve 75 Microphone
In theory, fixing a broken microphone wire is simple. It’s easy to explain, at least. You need to open the right cup without damaging any plastic parts (remove the earcup covers on both sides).
Then, unsolder the wire from the PCB and the microphone’s boom arm. Finally, you need a new wire of the same length and thickness to replace the old one. Run it through the PCB and solder it to the PCB and to the boom arm.
Additionally, you can alter the wiring by using two pieces of wire. You will run one wire from the PCB through the hole on the PCB to the other side where it gets anchored. The second wire will go from the anchor to the boom arm. That way, you will avoid damaging the wire in the future – the wire will not rub against the PCB since the moving wire doesn’t go through the PCB anymore.
In practice, fixing the microphone on your own is not an easy task. I followed the video below, and it took me about 3 hours to finish the job. If you don’t feel confident or don’t have the necessary tools, look for an experienced technician and pay for the repair.
