I couldn't resist [Gangnam style nun dance]


I'm trying to add an external mic for my Ipad. I have a headset XLR mic and an adapter to fit the headset input.

It doesn't appear to be working. The regular mic seems to be picking up the sound better than the external mic.

I'm wondering it's because:
A. I need to manually turn the headphone to a mic input somehow?
B. Use a powered mic.
