WM-703C

The WM-703C is the more fully specified high-end playback model in Sony's late-1989 slim premium family, combining auto-reverse, Dolby B and C noise reduction, Dynamic Bass Boost, an EX Amorphous head, anti-rolling stability, and logic control with hold lock in one of the smallest bodies of its year. A cable remote and carry pouch completed the package, but the real emphasis was on how much performance and polish Sony could compress into a genuinely pocketable machine. It was compact, but with very little feeling compromised.

This is one of those late-cassette Walkman where the engineering has already become quiet. Sony was no longer trying to prove that premium portable cassette audio was possible, but simply delivering it in a form that felt resolved, expensive, and easy to live with. The 703C is part of the stage where the high-end Walkman stopped being surprising and started being deeply refined.
