How to upgrade the firmware on a Sennheiser OfficeRunner

, ,

There is no information on the internet on how to upgrade the firmware on a Sennheiser OfficeRunner. All available information is on the DW series, which does not apply to the OfficeRunner.

You can upgrade the firmware using the Sennheiser HeadSetup software that is normally used to connect the OfficeRunner to a softphone such as the 3CX IP PBX softphone.


  1. Download and install the Sennheiser HeadSetup software.
  2. Right-click the new HeadSetup tray icon and select Open.
  3. Click the Updates tab.
  4. Click the Check for update button.
  5. This process will also validate your current firmware version.
