Sony NW-ZX100HN 128GB Hi-Res Walkman Digital Music Player (Silver)

The silver NW-ZX100HN Walkman from Sony is a high-resolution digital music player featuring audiophile quality playback with Bluetooth compatibility, 128GB of internal storage, and a lightweight, highly rigid aluminum frame. The Walkman uses the S-Master HX digital amplifier, which was developed to provide high resolution playback utilizing a mastering-quality digital amplifier for a wide frequency response, while minimizing distortion and noise. Other enhancements include an upgraded audio pathway by filling the VIA hole in the printed circuit board with copper to help lower the impedance and stabilize the power line of the circuit, which facilitates a firm bass sound, bright high ranges, and clear vocals.
