Functionally, the MS and UC certified headsets are almost identical. The main difference is the pre-configured headset settings.

The MS models are certified for Microsoft Skype for Business (Lync) and support Microsoft Skype for Business right out of the box. These models support call answer/end, volume control and mute without the need for additional configuration or settings. You can simply plug in and use the headset.

If you or your company do not use Microsoft Skype for Business, choose the standard UC model. Likewise, all the features you see in the MS models work with your favorite softphone right out of the box. Just plug it in.
