[[Portable CD player]]s that can decode and play MP3 audio files stored on CDROMs ([[MP3 CD]]s) are also effectively MP3 players. When the first units of these were released, such players were typically a less expensive alternative than either the hard drive or flash-based players. The blank [[CD-R]] media they use is inexpensive. These devices have the feature of being able to play standard [[audio CD]]s. Since a CD can typically hold only around 700 megabytes of data, a large library will typically require multiple discs. However, some higher-end units are also capable of reading and playing back files stored on larger-capacity [[DVD]]; some also have the ability to play video content, such as movies.

Players that connect via (Wi-Fi) network to receive and play audio can also be considered PMPs.<ref>{{cite web |title=The Wireless Music Player: Do-it-yourself remotely managed music player |url=http://devices.natetrue.com/musicap/ |url-status=dead |archive-url=https://web.archive.org/web/20060218045901/http://devices.natetrue.com/musicap/ |archive-date=18 February 2006 |publisher=natetrue.com |df=dmy-all}}</ref> These units typically do not have significant local storage and must rely on a server, typically a personal computer also on the same [[Computer network|network]], to provide the audio files for playback. [[Smartphones]] can also be considered PMPs as they have most of the media functions of a typical PMP.
