Updates focused on incremental improvements in battery, connectivity, and interface clarity while upholding the emphasis on superior sound. The lineup remained intentionally focused, serving its established audience with quiet confidence.
NW-ZX707
The NW-ZX707 is the most mature modern expression of the ZX Series concept. It combines Android 12, 64GB of internal storage, a 5-inch touchscreen, Wi-Fi, Bluetooth, USB-C, microSD expansion, USB DAC capability, and balanced output with Sony's current premium audio technologies, positioning it as a compact high-end Walkman built for both local high-resolution playback and streaming use. Unlike the earlier ZX models, which often felt like the line is still deciding what it wanted to be, the ZX707 arrives as a fully settled product. It carries forward the premium ambitions of the ZX1, the playback seriousness of the ZX300 generation, and the streaming-era flexibility reintroduced by the ZX507. In that sense, it stands as the modern synthesis of the entire ZX line.
NW-A306
The NW-A306 is an A Series Network Walkman with 32 GB storage supporting MP3, WMA, AAC, FLAC, ALAC, AIFF, Linear PCM, DSD, APE, and MQA playback. A 1280x720 LCD display showed track information while a lithium-ion battery delivers up to 36 hours of use. Touchscreen control, Bluetooth, Wi-Fi, NFC, USB-C, video and photo playback, S-Master HX, DSEE Ultimate, DC Phase Linearizer, and Vinyl Processor were included. This Walkman model continued the high-resolution A Series as a mid-capacity model in the 2023 lineup.
