D-EJ721

The D-EJ721 came from the phase where most of the format's practical problems had already been solved, allowing the design to focus on lightness, simplicity, and everyday usability. It combined G-Protection with a clean body and remote-based controls in a package meant for regular carry.

This defines its role clearly. The D-EJ721 is part of the part of the lineup where portable CD had become dependable enough that the best players were the ones that stayed out of the way.
