NW-A866

The NW-A866 extended the seventh-generation A Series touch-panel design to 32 GB. It incorporated Bluetooth connectivity. It features 32 GB storage for ATRAC, MP3, WMA, and AAC files along with video and photo playback. Lithium-ion battery life reached 36 hours, with S-Master MX and Bluetooth.

The A866 is the more balanced version of that shift. It keeps the same refined A identity, but with enough capacity to make the platform feel complete. The tension between old and new is still there, but it feels controlled instead of unresolved. Sony moves carefully here, and it helps.
