NW-A57

The NW-A57 is an A Series Network Walkman with 64 GB storage. A lithium-ion battery provides up to 45 hours of use with Bluetooth, digital noise cancellation, DSEE HX, and Vinyl Processor. Earphones and wireless earphones were bundled with some units.

The flagship 64 GB variant completed the 12th-generation A Series with full wireless capability. The A57 capped that generation and represents the fullest late non-Android A Series expression before the line changed direction again. At this point the line felt disciplined: compact body, long battery life, strong audio focus, and just enough wireless flexibility to feel current without becoming phone-like.
