1981
WM-3
The WM-3 is a playback-only Walkman. It features a tape selector and uses AA batteries. It is an early playback-only device that supports switching between tape types.
Introduced in 1981, the WM-3 rebranded the original TPS-L2 under Sony's new numerical naming system, bringing order to an expanding global lineup. Built on the same sturdy chassis derived from the first Walkman, it stood apart from the ultra-compact WM-2, offering a higher-end choice for listeners who valued dependable mechanics over extreme miniaturization.
Sony's engineers focused on polish rather than reinvention. A proper tape-type selector replaced the crude "High/Low" tone switch, enabling full playback of Type IV Metal tapes and noticeably improving sound quality. The DC input was standardized across models to simplify accessories and production.
Visually, the WM-3 adopted a matte-black finish in place of the blue and silver tones of the TPS-L2, giving it a more professional, confident look. In select regions, a gold-plated WM-3EX "Excellent" edition elevated the Walkman to a luxury object. Together, these updates brought the original design to its most mature form, the point where Sony's first-generation Walkman concept reached completion.
