NW-E105

The NW-E105 shared the fourth-generation E Series compact disc-style body with 512MB of built-in flash storage. It supports ATRAC and MP3 playback displayed on an LCD screen and provides around 70 hours of battery life from one AAA cell. It delivers mid-range capacity within the more pocketable redesign of the E Series.

The middle-capacity version of the same compact redesign that pushed the E Series further into compact, styled flash hardware. By this stage, Sony had a stable enough formula that the differences between models were often more about positioning and storage than about deeper conceptual changes. It is the practical center of that compact redesign generation.
