SONY WM-EX404 Walkman Cassette Player

All servicing details are shown in the photos.
I don’t just aim for “it works.” My standards are higher — I aim for “it works perfectly.”

This WM-EX404 has been carefully serviced and checked:
1. Motor serviced and lubricated — stable and consistent tape speed.
2. Playback head cleaned and serviced — excellent stereo playback with both channels working properly.
3. Circuit board checked — in very good condition.
4. Tape speed calibrated using a 3 kHz test tape to ensure the correct standard speed. This is especially important with vintage cassette players. If the tape speed is off, even a perfectly good cassette can sound terrible.
5. Powered by 2 × AA batteries — easy to find and replace anywhere.
6. Electronic-controlled mechanism — a more refined and integrated mechanism compared with basic mechanical designs.
7. Dolby, Groove and Mega Bass — giving you plenty of options to tailor the sound to your taste.

Sony has always had a special sound, and this player is particularly enjoyable with vocals and acoustic music. It is a lovely machine for anyone who appreciates the character of vintage cassette playback.
Let’s be honest — where can you buy a decades-old cassette player today and know that it has actually been properly serviced, rather than simply tested with “it works”?
With vintage cassette players, age alone doesn't tell you much. Without proper servicing and calibration, you may end up with unstable speed, poor channel balance, or a disappointing listening experience.
That is exactly what I aim to avoid.

The price is for the player only. Batteries and cassette tapes are not included.
Collection is welcome, and you can fully test the player before buying. I will provide batteries and a cassette for you to test it during collection. If you're happy with its performance, then you can go ahead with the purchase.
