What is MP3 player?
[[File:IPod_5G,_nano_2G,_shuffle_2G.jpg|250px|thumb|The iPods are very popular MP3 players.]] An '''MP3 player''' is a portable audio player people can use to listen to [[song]]s saved in the [[MP3]] format. They can use [[USB]] cords or [[Wi-Fi]] to connect the device to computers, so that [[computer file]]s can be transferred to players internal memory. MP3s are audio files that have been made smaller by removing sounds that the human ear cannot hear. Many newer MP3 players can also be used to view images or movies, or play games, and can also play other formats, such as [[FLAC]] and MPEG-4 [[AAC]]. The most well-known MP3 player is the [[iPod]]. MP3 players can also be built-into a car or home stereo. They were popular around the early 2000s but slowly lost popularity to the introduction to smartphones and apps like Spotify. Even with this loss in popularity, you can still get one today that can even connect to Spotify. {{Tech-stub}} {{commons|mp3 player}} [[Category:Electronics]] [[Category:Audio technology]]
