WM-805

The WM-805 explored a wireless control system that separated daily operation from the cassette mechanism. The player transmitted audio to a cordless headset and sent transport information to a wireless LCD remote, creating a setup where most interaction happened away from the main unit.

Commands returned through the same RF channel, so listeners could control playback without handling the cassette body. The wireless architecture shaped both the design and the materials.

To avoid blocking the signal, Sony used a plastic enclosure rather than a metal shell, and the unit weighed 185 grams without its battery. A sixteen-code pairing system prevented nearby remotes from interfering with each other.

The WM-805 was aimed at early adopters who wanted a new way to interact with a cassette Walkman. Its short runtime limited portability, but it showed how far wireless control could be integrated into an analog system before digital formats reshaped portable audio.
