How to Record Both Mic Audio and Speakers while using headset
I've seen many questions like this. The simple solution is Soundflower. You can download it for free at http://cycling74.com/products/soundflower/. As to where you're recording, you would need to select the Soundflower (2ch) or Soundflower (16ch) as your input. 

Input 1 = your microphone's audio/your babbling
Input 2 = your speakers' output
