Sony NWZ-ZX1 Walkman® with High-Resolution Audio and 128GB Storage. 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. Hear detailed, authentic sound on the move with High-Resolution Audio. With higher sampling and bit rates than CDs, High-Resolution Audio gives a wider dynamic range, for crisper highs, richer lows, and greater subtleties. This Walkman lets you enjoy your favorite music in PCM (WAV/AIFF), as well as lossless formats like FLAC (192kHz/24bit) and ALAC. Uniquely developed for High-Resolution Audio, S-Master HX digital amplifier reduces distortion and noise through a wide frequency range. That enables detailed reproduction of high frequency sound, ensuring fidelity to its original source. The Digital Sound Enhancement Engine (DSEE) upscales your compressed digital music files (MP3, ACC, ATRAC, and WMA) to CD quality. By restoring the high-range sound lost in the compression process, DSEE reproduces your digital music files in rich, natural sound, closer to the quality of the original recording.
