NWZ-B152F

The NWZ-B152F added FM radio to the 2 GB B Series entry-level design. It stayed within the simple portable audio branch. With 2 GB flash memory supporting MP3 and WMA files, it includes LCD display, 18-hour battery, direct USB, FM radio with recording, and ZAPPIN.

The FM-equipped B152F takes that same stripped-down approach and adds a compact amount of flexibility without changing the core idea. Sony is not trying to elevate the player, just to make it more useful when you were not relying on your own library. The additions stay grounded in actual use instead of feature inflation.
