Often digital audio players are sold as MP3 players, even if they support other file formats. Other types of electronic devices like cellphones, internet tablets, and digital cameras are sometimes referred as PMPs because of their playback capabilities.

MP3 players are portable CD players that can decode and play MP3 audio files stored on CDs. Such players are typically much less expensive than either the hard drive or flash based players.

The name itself is a misnomer, since most MP4 players are incompatible with the MPEG-4 or the .mp4 container format. Instead, the term symbolizes their status as successors of MP3 players.
