MSFT Band has Microphone what can it be used for?

[Windows Central Question]

I know the MSFT has a microphone. Doesn't seem that I can use it as a way to talk in the phone, likely because there is no speaker to hear, but I can see solutions to that.

What is the primary design use for the microphone?

Thanks,
