How To Install EPOS Connect

For this update, have the Sennheiser wireless microphone docked and the USB plugged into the headset AND computer. You should see a blue light on the headset when it is connected.

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




  • Go to the EPOS Connect software page.
  • Scroll down to where it says “Download EPOS Connect software”, then select “EPOSConect_4.2.0.974.exe” to download.

  • Note: version number is subject to constant change. Just make sure you are downloading the .exe file.

  • Install EPOS using the installation wizard, then it should place an icon on the desktop that looks like a weird “E”.

  • Note: You may need to get permission from IT before installing this program, much like we do.

  • Open the EPOS Connect and on the second line, where you see an image of your Sennheiser base, click “Update.”  Allow this program to run, then reboot your computer.  After a reboot, if you open the Sennheiser Updater program again from the gray gears icon on the desktop, it will show the updated version.

  • If update button is grayed out and unclickable, click on the "Options" button on the right, then select "Check for updates". After a couple minutes EPOS Connect should find the updates for you.

  • When the update is complete, test your Sennheiser headset. It should now be working. But if not, give us a call at 800-923-0018
