WM-WX808

The WM-WX808 is a wireless cassette Walkman from 1992 that shifted Sony's cord-free listening concept toward greater everyday reliability instead of spectacle. It transmitted audio over a higher 238 MHz RF band to a matching belt-clip receiver, reducing the interference problems that had affected some earlier wireless systems. The main unit retained auto-reverse playback, Dolby B noise reduction, and Mega Bass in a fairly conventional cassette body powered by standard AA batteries, making the machine itself easier to live with than some of the more elaborate wireless experiments before it.

This is one of those models where Sony's wireless branch starts feeling less of a futuristic side project and closer to an attempt to become practical. The WX808 was not trying to reinvent portable listening so much as make one specific convenience work with fewer tradeoffs. It is a cleanup model in the best sense: less ambitious on paper, but probably easier to use in the real world.
