This is bound to improve interaction between lecturers/speakers and the students/ audience. Since it is kinda of shock resistance it can easily be moved around with getting damaged. I have a very long pitched voice but I loved sitting at the back (oh, I used to get to the class late) in my college days, this means I was always discouraged to ask questions. This will make any lecturer or speaking event much more engaging (sleepers alert), Interactive and fun. Great product @calprut.
