NW-A55WI

The NW-A55WI is an A Series Walkman with 16 GB storage. A lithium-ion battery delivers up to 45 hours of use with Bluetooth, DSEE HX, Vinyl Processor, and bundled wireless earphones.

The WI variant emphasized wireless listening within the 12th-generation A Series. It pushes that same platform toward wireless presentation while the player still is part of the classic dedicated A-series worldview. Wireless convenience was being added around that identity, not replacing it or rewriting the reason the product exists.
