It used to be that people enjoy music only while they are home or when they go to a classy restaurant or when they attend a musical. It was not until lately when music players have begun to be mobile. Do you remember people holding a big stereo over the shoulder while walking? Usually they are those who are on their way to the beach. Then the Walkman came out. It took off the strain on the shoulder but it has limited the music to the sole listener. Now, we have the mp3 to mp5 players and most with their phone, you only need a set of sony headphones to enjoy with bliss.
