NW-ZX507

The NW-ZX507 was a ZX Series Network Walkman with 64 GB of internal storage and support for high-resolution formats including DSD. It used a touchscreen interface, Bluetooth, Wi-Fi, NFC, USB-C, microSD expansion, balanced output, USB DAC support, and advanced audio processing.

The ZX507 brought Android back to the ZX Series after the playback-first ZX100 and ZX300 generation. That changed the product's behavior: it was no longer aimed only at listeners managing local high-resolution files, but also at people who wanted enthusiast hardware with modern app-based listening in the same device.

It sits at the point where the ZX concept reconnected with streaming-era habits while keeping the dedicated hardware and audio focus that separated it from ordinary smart devices.
