where can I get the datasheet? I tried a google search of the part number but came up with nothing.

I found a very similar data sheet. https://www.cui.com/product/resource/cmb-6544pf.pdf

Can I use these to listen to a conversation and how would I hear it

These are not recommended for voice or music. They would work, but the sound quality would be very very poor.

What voltage does the microphone need ?

Start low, 3v or so and go up as needed

How do you tell which lead is plus and minus?

3 lines on the negative side, you will see what I mean
