Steps to Troubleshoot Jabra Evolve2 75 Microphone

1. Update Firmware with Jabra Direct

One of the first things fixes to try if you're experiencing mic issues with your Evolve2 75 is make sure it's running on the latest firmware. Jabra has rolled out several updates over the years, and some specifically address microphone issues. Keeping your headset up to date is a quick way to ensure everything's running smoothly.

Here’s a simple guide to updating the firmware on your Evolve2 75:

• Download Jabra Direct: Visit the Jabra website and download the Jabra Direct software.
• Install and Launch Jabra Direct: Follow the installation prompts and open the software once installed.
• Connect Your Headset: Use the provided USB dongle to connect your headset to your computer.
• Check for Firmware Updates: In Jabra Direct, select your device and check for available firmware updates. If an update is available, follow the instructions to install it.

Updating your firmware can often fix performance glitches and even boost how your headset functions overall. Hopefully, that’s all it took to get your mic working again. But if it didn’t, don’t worry—we’ve got more troubleshooting steps to walk you through. Let’s keep going and get this sorted, step by step!

2. Only Use the USB Dongle

If your Evolve2 75 mic is still acting up, here’s another thing to double-check: Are you using both the USB dongle and Bluetooth at the same time? That can sometimes cause conflicts and lead to connection issues. Try sticking with just the USB dongle for a more stable setup!

3. Turn Off Noise Suppression in Call Software

If you're using video conferencing software like Zoom, Microsoft Teams, or Google Meet, you might be running into a mic noise-canceling conflict. Here’s why: most of these platforms have noise-canceling built in and turned on by default. At the same time, your Jabra Evolve2 75 also has noise-canceling in its mic.

When both are active, they can end up clashing, affecting your mic’s performance. A quick fix? Try turning off the software’s noise suppression, or set it to the lowest setting. This simple tweak often resolves the issue!

• Access Audio Settings: Open the settings menu in your call software (e.g., Zoom, Microsoft Teams).
• Modify Noise Suppression: Look for a noise suppression setting. If it’s available, turn it off or set it to the lowest level. Since the Jabra Evolve2 75 has built-in noise cancellation, additional noise suppression from the software can create conflicts and degrade microphone performance.

How to turn off Noise Suppression in Microsoft Teams

1. Go to Settings. You can find this by clicking the three dots in the top right of the app, next to your profile.
2. Select Devices. This will be on the left hand navigation section.
3. Scroll down to 'Noise Suppression' and turn it off.

How to turn off Noise Suppression in Zoom

1. Go to Settings. You can find this by clicking your profile icon in the top right of the app.
2. Select Audio. This will be on the left hand navigation section.
3. Scroll down to 'Audio Profile' and under 'Zoom background noise removal' select Low.

4. Disable Intel Smart Sound Technology on Windows

If you’re on Windows, Intel Smart Sound Technology could be behind your microphone issues with the Evolve2 75. To check this, head over to Device Manager and look for anything with "Intel Smart Sound Technology" in the name. Disabling those devices often clears things up!

Here's how to disable it:

• Open Device Manager: Click the Start menu, type "Device Manager," and select it from the list.
• Find Sound, Video, and Game Controllers: Scroll down to this section and click the arrow on the left to expand it.
• Disable Intel Smart Sound Technology: If you see Intel Smart Sound Technology listed, right-click on it and choose "Disable device." Repeat this for any Intel Smart Sound Technology device listed.
• Restart Your Computer: After disabling this setting, restart your computer to ensure the changes take effect.

Disabling Intel Smart Sound Technology can help resolve conflicts that might be interfering with your headset’s microphone. It’s a quick step that could make all the difference!

5. Additional Troubleshooting Tips

If the steps above didn’t solve your microphone issues, here are a few more tips:

• Contact Jabra Support: If your headset is still under warranty, reach out to Jabra for help or a possible replacement.
• Explore Alternative Headsets: If you’ve already gone through several replacements and still have issues, it might be time to explore a different model. We’d be happy to help you find the perfect fit for your needs!
