NW-A27HN

The NW-A27HN was the 64 GB model in Sony's ninth-generation A Series. It supported MP3, WMA, AAC, FLAC, ALAC, AIFF, and Linear PCM playback, with digital noise cancellation, WM-PORT, bundled earphones, and a lithium-ion battery rated for up to 50 hours.

The higher storage made this compact high-resolution A platform feel complete. It gave listeners enough room for larger lossless libraries while keeping the non-Android A Series focused on battery life, portability, and local playback. Compared with earlier A models, the identity was clearer: small, premium, and dedicated to high-resolution listening without turning into a phone-like device.
