NW-F805K

The NW-F805K is a first-generation F Series model and Android successor to the A Series. It matched the 16 GB storage, Android 4.0, 800x480 display, 25-hour battery, touchscreen, Bluetooth, Wi-Fi, FM radio, speaker, WM-PORT, video and photo playback, Clear Audio+, DSEE, and Walkman Classics Application of the core F805.

The K version takes that same first-generation F platform and wraps it in a more accessory-led presentation. The real story is still the same: Sony trying to make a compact Android Walkman feel like a credible product category instead of a one-off curiosity. The platform underneath had enough confidence to support variants in the first place.
