The Walkman F series is a discontinued portable media player manufactured as a part of Sony's Walkman line of music players, through two generations.

They are high-res compatible players and run the Android operating system.

The F800 was the first ever Walkman to support the playback of FLAC audio files.

It was the first Walkman player to support high-resolution audio sources (192 kHz/24-bit).

In its review for the NWZ-F886, Trusted Reviews gave praise for "superb" hi-res audio quality, display and battery life, but criticised the provided headphones and that its 32 GB storage could be quickly filled with hi-res files.
