NWZ-E454K

The NWZ-E454K incorporated speaker output in the 8 GB E Series model. It maintained the updated processing tools of the family. With 8 GB storage for MP3, WMA, AAC, and WAV playback plus video and photo, it uses a 240x320 TFT display and 50-hour battery. FM radio, built-in speaker, WM-PORT, DSEE, Omakase Channel, and Lyric Pita completed the setup.

The speaker-equipped version of the E454 nudges the same platform toward more casual, shared use. It is still recognizably an E Series Walkman, but Sony clearly wanted to make it slightly more flexible in how it could be uses around the house.
