Sennheiser Headsetup Computer Application

Headsetup is an older Sennheiser program which was used to change settings in the headset that couldn't be changed without it. Things like allowing remote answering with softphones and changing the default headset mode were available with this program.

We have since moved to another application known as EPOS Connect, which does what Headsetup did, but with the added ability to update firmware.

The software that is included with the OfficeRunner is not required for computer use, however it can be used to set the OfficeRunner as the default device on the computer, enables remote phone pc switching with a handset lifter, among other things.

If the software is installed you will need to open the program and go to “Settings” and enable “Always Audio”. If this is not done the headset will not stay in Computer Mode.

There is a new version for Headsetup for Mac now! Go to the Sennheiser Software page to download it:

Windows sound control panel audio settings tab


  • Ensure that the USB cord is securely connecting the base to the computer
  • Check in the computer’s sound settings that the DW Office is the default device for Sound and Recording
  • You may need to disable any other devices selected in the Playback & Recording tab

If you’re still having a problem:

Find out if you still have the Headsetup program installed. If you do, bring up that program and click on SETTINGS.

From here make sure that ALWAYS AUDIO is selected (NO RED LINE THROUGH IT).

If you have taken all these steps and still having issues, it is often helpful to restart your computer as well!
