NW-S755K

The NW-S755K incorporated built-in speaker in the 16 GB eighth-generation S Series model. It kept the rounded redesign and universal noise cancellation. It offers 16 GB storage for MP3, WMA, AAC, and WAV files, video, and photo playback. The 42-hour lithium-ion battery, WM-PORT, Omakase Channel, noise cancellation, and speaker completed its functions.

The K version keeps the same S755 platform and extends it into the same accessory-driven packaging as the rest of the family. The role remains unchanged.
