The students should not to be able to listen MP3 players on headphones during class because it will ruin the environment in the class. If every student is using MP3 players on head phone during class then how they can respect their teachers. Students can’t focus on their lectures while given by the teachers so they should not be allowed to listen MP3 during class. Also excess of everything is bad if they listened to more and more music using headphones it will also reduce their sense of hearing.
