How to Install EPOS Connect/Update your Firmware

Begin with the headset on the headset base and make sure the headset base is connected to your computer with the Sennheiser USB cord.

If your headset doesn't have a charging base, use the USB charging cord that came with it and plug that into the computer.

We don't recommend updating your headset's firmware unless necessary. If you want help before or during the update, give us a call at 800-923-0018

1. Go to the  EPOS Connect software page.
2. Click the download button for your operating system. If you use Windows, click "Download for Windows" and so on.



3. Go to your download folder or click on the finished download pop-up to install EPOS and use the installation wizard. It should place an icon on the desktop that looks like a black stylized “E” logo.
   Note: You may need to get permission from your IT before downloading and installing this program.

How to update your firmware

1. Click on the black "E" logo to open EPOS Connect. Then, click on the second icon at the bottom of the page. It should look like a circle made of two arrows.
2. Click "Check for Updates" on the right of the screen and let it run.
3. If it says that an update is available, click "Install Updates."
4. After a few minutes, it should say that your headset has been updated!
5. When the update is complete, test your Sennheiser headset to make sure it turns on and works correctly. Sometimes this update can drain the battery, so if those battery lights aren't lit, you will need to let it charge.
6. If the headset is still not working, or if the update did not complete successfully, give us a call at 800-923-0018!
