This model replaced the WM-51 and was very similar in concept, if not execution. The idea of a compact an neatly styled auto reverse Walkman was retained, though the new look changed the main colour from white to dark grey, whilst making the “Walkman” logo bigger and the cassette window smaller. Inside, a similar mechanism was used, though some simplification had clearly taken place as only one large metal spool carrier trim was present, the other spool carrier was much smaller and unembellished. The mechanism did see the return if the “dual azimuth” system however, where the head angle could be adjusted separately for each direction of playback. The auto-reverse mechanism also included two LED indicators to show the direction of tape play, a new feature for this series of models. Text copyright © Walkman Central.

Power came either from a single “AA” sized cell, or a rechargeable battery (which was included, along with the charger). The headphones were of a special type that were not available separately, and as before could be retracted and stored in the machine using a winding wheel at the rear. Unlike the previous WM-51 however, the headphones were well protected by a hinged cover when not in use. A small slot in the cover allowed it to be closed even when the cable was extended and the headphones were in use. The cassette door was protected against accidental opening by a catch with was operated by the “stop” key, with a extra latch controlled by a slide switch to prevent mis-operation.

A second pair of headphones could be connected, using a conventional socket. Unfortunately, this did not mute the built-in pair (which left something to be desired when it came to both comfort and sound quality), thus wasting power and potentially causing a needless public disturbance.

It would seem that at some stage there had been an intention to refer to this model as the WM-52. This would certainly have seemed logical since it effectively replaced the WM-51, but in the UK at least this was not to be. The printed circuit board is in some cases marked “WM-52” and one of the UK catalogues shows what is referred to in the text as “WM-106” with the “52” of WM-52 crudely obliterated from the picture.
