The main difference between the two models lies in the certification and the preconfigured settings for various communication platforms.

- Certification: One model is optimised for Microsoft Teams (MS), the other for Unified Communications (UC) such as Skype for Business, Zoom or other UC platforms.
- Settings: The MS variant is specifically tuned for Microsoft Teams, while the UC variant is configured for a wider range of communications applications.
- Functionality: Both models offer plug-and-play functionality and can be used wirelessly with a USB-A connection. The basic functions such as volume control and stereo sound are identical.
- Compatibility: Both headsets work with most common communication applications, but the MS version offers special features for Microsoft Teams.

The differences therefore mainly concern the software integration and not the hardware.
