Nearly all DAPs consists of some kind of display screen, although there are exceptions, such as the [[iPod Shuffle]], and a set of controls with which the user can browse through the library of music contained in the device, select a track, and play it back. The display, if the unit even has one, can be anything from a simple one or two line monochrome [[LCD]] display, similar to what are found on typical [[pocket calculator]]s, to large, high-resolution, full-color displays capable of displaying photographs or viewing video content on. The controls can range anywhere from the simple buttons as are found on most typical [[CD player]]s, such as for skipping through tracks or stopping/starting playback to full touch-screen controls, such as that found on the [[iPod Touch]] or the [[Zune HD]]. One of the more common methods of control is some type of the [[scroll wheel]] with associated buttons. This method of control was first introduced with the Apple iPod and many other manufacturers have created variants of this control scheme for their respective devices.

A standard PMP uses a 5-way [[D-pad]] to navigate. Many alternatives have been used, most notably the wheel and touch mechanisms seen on players from the [[iPod]] and [[SanDisk Sansa|Sansa series]]. Another popular mechanism is the swipe-pad, or 'squircle', first seen on the [[Zune]]. Additional buttons are commonly seen for features such as volume control.
