NWZ-F804

The NWZ-F804 is an F Series Network Walkman with 8 GB of storage supporting MP3, WMA, AAC, FLAC, and WAV playback. It features an 800x480 TFT display and a lithium-ion battery rated for 25 hours. Touchscreen control, Bluetooth, Wi-Fi, FM radio, speaker output, WM-PORT, video and photo playback, Clear Audio+, and DSEE were standard.

One of the first really clear signs that Sony was trying to push the Walkman into a smartphone-adjacent future instead of simply extending the old flash-player formula. The F Series was built around Android, touch control, wireless features, and a much broader media identity, which immediately made it feel like a different category of Walkman from the classic button-driven lines below it.
