NW-S764K/NI

The NW-S764K/NI is a color variant of the speaker-equipped ninth-generation S Series model. It carries built-in Bluetooth. It features 8 GB flash storage for MP3, WMA, AAC, and WAV playback plus video and photo. The lithium-ion battery lasted 42 hours, with WM-PORT, Clear Phase, Bluetooth, and speaker.

This unit carries the same broader role as the base model. The suffix changes the presentation, not the role.
