NW-S738FK

The NW-S738FK is the higher-storage version of the sixth-generation S Series Network Walkman. It carries forward the Omakase Channel introduction and unified design updates from earlier models. It offers 8 GB flash memory for MP3, WMA, AAC, and WAV files along with video, photo, FM radio with recording, noise cancellation, the 240x320 LCD display, 40-hour lithium-ion battery, built-in speaker, Clear Audio Technology, and expanded playlist functions.

The S738FK does the same thing in a slightly more balanced capacity tier. This is where Sony's late classic S Series starts to feel almost luxurious in its own way: compact, polished, and complete enough that it can carry variants without feeling watered down.
