My leisure activity is listening to music. I often do it in my free time and it makes me relax after a long time study at school. And how to listen to music? I think all people know it. All thing we need a CD (if we use cassette), a phone (if we don't use cassette), a headphone. And some people ask me: "why do you use headphone" Because I don't want makes noise to people near me. If you use cassette you only put the CD into the cassette and choose the song. If you use phone, it's easier, you just only turn on MP3... and choose the song you want to hear? Which ways is easier? Give your ideas under my comment.
