NW-A45HN

The NW-A45HN is an A Series model with 16 GB storage supporting APE and MQA playback along with MP3, WMA, AAC, FLAC, ALAC, AIFF, and Linear PCM. It uses a 45-hour lithium-ion battery with digital noise cancellation, S-Master HX, and bundled earphones.

The HN variant added earphones to the core 11th-generation platform. It is best understood as a packaging branch of the same compact high-resolution A line. The player's real importance stays the same: this is Sony's modern, listening-first Walkman operating from a place of clarity instead of confusion.
