NW-A55

The NW-A55 is an A Series Network Walkman with 16 GB storage. A lithium-ion battery delivers up to 45 hours of use with Bluetooth, DSEE HX, and Vinyl Processor. It advanced the A Series into the 12th generation with enhanced audio processing.

The A55 is where Sony refreshed that same compact premium A idea without breaking it. The additions matter, but what matters more is that Sony understood the formula was already strong and chose to refine it instead of replace it. Features like DSEE HX and Vinyl Processor belong to that mindset. The A55 reflects Sony refining the dedicated non-Android A formula into something very stable and very hard to misunderstand.
