TWO MICROPHONES ON IPAD

Hello everybody,

I have two clip-on microphones and I want to use them simultaneously with my IPAD. Which adapter I need to connect them and also, If it's possible, headphones?

I mean, there is any adapter for two mics and headphones for IPAD?

I'm recording videos with two speakers and I want to improve the sound with the clip-on mics.

Thanks a lot,

Joan
