The MD-ST501 comes in three colours - ghastly white, nasty yellow and a very handsome blue.

As thick as two MD cases and is the same size as an MD jacket.

The machine includes the single-shot random playback feature - it plays all tracks, in random order, once, then shuts down. The machine also has an optional autoplay mode (Only when using the internal battery for some reason). When you insert the disk, play starts immediately.

40 seconds of anti-shock memory, and has the 24-bit ATRAC.

A back-lit "skeleton type" LCD remote control. (See-through).
