Random idea...

I wonder what the simplest cheap way to implement this would be?



Preferably involving not much more than throwing some standard, easy-to-find ICs and a mic and headphone socket onto a board and hooking on some batteries, a mic, and headphones.


Or is this just a really stupid idea to begin with?
