How MP3 Players Work

The MP3 player is the most recent in an evolution of music formats that have helped consumers enjoy their tunes. Records, 8-track tapes, cassette tapes and CDs -- none of these earlier music formats provide the convenience and control that MP3 players deliver. With an MP3 player in hand or pocket, a consumer can create personalized music lists and carry thousands of songs wherever

they go.

All of that stored music and the MP3 player itself fit into a device that, in some cases, weighs less than one ounce. Portability is a large factor in the popularity of the MP3, considering the ease of transportation in comparison to a CD player and CD storage case. In addition, some devices provide additional technology, like video and photo viewing, alarm and calendar functions, and even cell phone and Internet service.­
