NW-E2

The NW-E2 is the U.S.-market variant of Sony's first flash memory Network Walkman generation. It offers 32MB of built-in storage and ATRAC playback on an LCD display, running on a single AAA battery for up to five hours. As a lower-capacity version of the NW-E3, it represented Sony's initial move away from Memory Stick toward integrated flash memory players in the compact E Series.

This model is part of the first real self-contained flash logic in the Network Walkman line. Music was no longer carries on external media. The player itself became the storage object, even if capacity was still very limited and the software environment remained tightly controlled. It served as the entry-level face of one of Sony's most important early shifts from card-based digital playback to sealed flash players.
