WM-WE01

The WM-WE01 appeared on July 1, 1999, as part of Sony's twentieth-anniversary Walkman lineup. It refined Sony's cordless cassette concept with a cleaner late-nineties exterior and GROOVE bass, continuing the idea of a compact player that transmitted audio to a wireless receiver for cable-free listening.

Its short-range link was tuned for stable transmission to cordless headphones, and Sony paired the system with a clip-on remote that made the setup feel more like an accessory-driven listening kit than a standard Walkman.

Auto Reverse, AMS track skip, Dolby B, logic control, and AVLS rounded out the feature set, keeping the WE01 aligned with Sony's higher-end cassette models even as its cordless design stood apart.
