How do I update the firmware on the Ambeo Soundbar?

14 April 2026 20:42 Updated

You can update the firmware via the Smart Control app or using a USB flash drive.

Download the update file "image.swu" from the Sennheiser website and save it to a 1 GB FAT-formatted USB drive.
Connect the USB drive to the soundbar and press the SETUP button for 5 seconds.
The display will show "Updating." The process may take up to 8 minutes.
