Megaphone is the new must have app for your iPhone!
Megaphone transforms your iPhone into an instant Microphone, PA system or Megaphone when you plug it into amplified speakers.
It is really simple. If you are at a party and playing music from your iPhone on the stereo, you can just launch Megaphone, and use your iPhone as a Microphone as you make a speech! You will never need to hire a microphone again.
