Sony introduces the ZX1 to Europe
NWZ-ZX1 Walkman
Enjoy High-Resolution Audio while you’re out and about with the Walkman® ZX1. Every single part, material, and feature of the ZX1 has been crafted by Sony engineers to realise the ultimate High-Resolution Audio experience on the move.
Sony’s S-Master HX Audio Amplifier reduces distortion and noise at wider frequency ranges, while DSEE HXTM up-scales existing sound files to near High-Resolution quality – making you feel as if you’re really there at the recording studio or concert. Whatever you’re listening you, unmatched mobile sound quality is further assured by Clear Audio+TM technology[ii] by bringing together the expertise in digital signal processing technologies that Sony has cultivated throughout its history.

And for even more revealing sound on the move, specially-selected precision components are teamed with thickened internal connecting cables and a super-rigid aluminium chassis. No compromise has been made to ensure absolute clarity of sound – including the use of extra-large ‘OS-CON’ power supply capacitors to maintain superb frequency response and minimise noise at the amplifier output stage. On top of this, the Walkman® ZX1 offers plenty of options for your listening pleasure. High-Resolution music files can be played in WAV, FLAC, Apple Lossless, and AIFF formats.
The new range High-Resolution Audio products from Sony are on sale in Europe from March 2014.
