NW-E507

The NW-E507 is the 1GB flagship of the fifth-generation E Series Walkman Stick lineup and the first to include an FM tuner. It supports ATRAC and MP3 playback from built-in flash storage shown on an OLED display and achieved up to 50 hours from a lithium-ion battery. The perfume-bottle-inspired design incorporated the new FM radio capability. It helped set the visual direction later carries into the flash A Series and later Walkman models.

The top-capacity version of the same mature Walkman Stick revision. By this point the E Series had stopped feeling transitional. The player was stylish, compact, rechargeable, radio-equipped, and far more coherent than the earlier flash generations. It stands as the fullest expression of the refined Walkman Stick formula before the line pivoted again into the Beans era.
