NW-A855

The NW-A855 belonged to the sixth-generation A Series Network Walkman family. It retained the A840 design and accessory compatibility while adding Omakase Channel. With 16 GB storage supporting ATRAC, MP3, WMA, and AAC playback plus video and photo, it uses a lithium-ion battery for 36 hours.

By this point the A Series had settled into its clearest role as the premium flash Walkman line, and the A850 family tightens everything around that idea. Thinner body, OLED display, and a more restrained design language shift the focus from feature-rich to well-finished. Earlier A models often felt like they were still negotiating what kind of premium device they wanted to be. The A855 does not carry that tension. The design feels edited, with less visual noise and less need to prove anything through features or styling.
