what if you are on the street and you hear a voice in your head that says "whos there", maybe is not your imagination and maybe you are not crazy, is a new campaign for a new TV show (paranormal state), that uses a new device, is a speaker, that uses lineal sound, so the speaker can be at several feets away, and you can listen it, as headphones.

here is the explanation
