The Venu 2 Plus model does have a microphone and speaker that allows you to take calls on your wrist. This is unique to this model and represents a long time coming within the brand. The Sense also has a microphone and a speaker as well, and has a better overall relay of the call thanks to the various voice assistant features built into the watch. However, the Venu 2 allows you to make emergency calls if needed and this is truly a great and useful feature when you are outdoors.
