What kind of external microphone can I use with my Galaxy smartphone? I'm feeling a bit stupid.

I want to make video podcasts using my Samsung Galaxy S3 but of course the internal mic isn't much good.

So i need an external mic.

Can I use pretty much any battery-powered mic and plug it into my phone (maybe needs an adapter?)

I bought an Edutige ETM 001 but it wasn't compatible. I'm told i need an Edutige EIM 001 but I'm in Asia at the moment and can't find one here...

I'd be grateful for your help!
Consider a couple of products from Australian microphone maker Røde.

Røde smartLav+: http://en.rode.com/microphones/smartlav-plus


Røde makes pretty high-quality products and are leaders in making new products like these mcicrophones which are designed to plug directly into the TRRS connectors of smartphones.

I have no connection with Røde except as a satisfied, paying customer.
