Sony Audio Chipset
The WM-EX612 printed circuit board (PCB) is well designed and fabricated and is similar to the one in the following Walkmans.
- WM-EX510
- WM-EX512
- WM-EX612
- WM-EX614
- WM-EX622
They simply install a different firmware that provides access to different functionality. Microcontrollers being one of my skills, I was very interested in looking at the firmware on the main IC.

The IC701 is the main microcontroller chip in a plastic package.
The design of this Walkman has undergone many revisions and improvements, and this model is one of the best.
