I remember the time, when cassette players appeared and at once became popular. Later portable CD players occurred. Everyone dreamed to have one. Of course, when they became cheaper they spread everywhere and their popularity has grown fast. Now they are in disfavor. MP3 players replaced CD players and more than that MP4 players exist today. Everyone who loves music and videos, appreciates the quality of its sounding will follow the progress in music players for sure. Consequently, a person will make choice in favor of such devices as MP3 or MP4 players, which are tiny and include favorite
music/video loaded from one's computer. What about listening to the music with no player?
