EPOPS Connect for Firmware Updates with Files

If you have not already installed EPOS Connect on your computer, you can download it here!


***Please ensure that you have the most recent files from Sennheiser before proceeding. These files can be found on the server at Employees (U:) > Product Support (Maintained by Matt) > EPOS Connect Firmware Files

***There will be two files from Sennheiser for this process. One will have “20MHz” in the file name. This will be selected to update the headset. The other file will be selected for the base.


***It is not necessary to update both devices. Headsets and bases can be updated individually.
