NW-E053K

The NW-E053K is the speaker-equipped 4 GB model in the eleventh-generation E Series. It marked the platform transition to Linux and plate-type body. Featuring 4 GB storage for MP3, WMA, and AAC files, it uses an LCD display and 30-hour battery. WM-PORT, DSEE, Omakase Channel, Lyric Pita, and built-in speaker were standard.

A speaker-equipped variation of the same late E platform, and one of those branches that only really works once the core player has already become stable. The added speaker does not change the player's identity, but it does make it feel a little more casual and self-contained.
