MP3 players have changed the way we listen to music on the move. With no need for tapes or discs, mp3 players can store days, if not weeks of music, giving us more choice than any other music players.
Although we call portable music players mp3 players, the majority of portable music players support more than just mp3. But whatever formats mp3 players may support, the same basic principles remains. Uncompressed digital music files are ripped from CDs, the data is compressed and copied to mp3 players. The resulting music files will be a fraction of the size that they were on the CD, allowing mp3 players to store large music libraries.
Early mp3 players favoured hard disks for storage, which allowed for large capacity, but also compromised battery life and limited how small mp3 players could be. Now most mp3 players use flash memory. With flash storage mp3 players enjoy better battery life, more robust build and reduced size, while still offering capacities up to 64GB.
Although
Apple is the clear market leader, there's still stiff competition from the likes of
Samsung and
Sony when it comes to mp3 players.
