Moman H2 mic question

[Fowler]

I just installed Moman H2 head sets on our helmets.
The mic has a rounded side with 4 holes and a flat side with more smaller holes.
What side goes toward the mouth

Bob,
Even Google couldn't help me answer this one...? Guess we'll have to wait on an experienced Moman H2 owner to show up..
