Watching a movie like Twister, you're surrounded by sheets of rain.
Thunder rumbles in the distance.
Flying cows whoosh hither and yon. To experience the effect, you need a stereo VCR that feeds a stereo receiver that offers surround sound. You wire your speakers and receiver to the box and plug in the phones. You can switch between headphones and speakers by pressing a button. Without the box, you have to feed eight flimsy wires to the receiver's speaker connectors.
