2011
NWZ-A864
The NWZ-A864 is the 8 GB model in Sony's 2011 A Series Network Walkman. It supports the family's FLAC playback addition in this generation. With 8 GB storage for MP3, WMA, AAC, and FLAC files plus video and photo playback, it relied on a lithium-ion battery for 36 hours.
This player carries the same broader role as the domestic A860 models. Sony is refining the A Series without breaking it, which is harder than it sounds at this point in the timeline. The player stays focused, premium, and clearly separate from more general-purpose devices. That restraint holds the generation together.
