The gold-plated NW-WM1Z Walkman from Sony is a high-resolution digital music player featuring audiophile-quality playback with Bluetooth compatibility, 256GB of internal storage, and a solid-sculpted oxygen-free copper body. 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 four wire braided cables engineered with KIMBER KABLE, FT CAP (high-polymer capacitor) that works to regulate power flow, and DSEE HX upscaling technology, which uses an algorithm to analyze your music and replace any lost information when needed. Additionally, the NW-WM1Z utilizes a DC Phase Linearizer that works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match six phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound.

The player supports music files up to 384 kHz/32-bit rate and DSD Native playback (11.2 MHz) and is compatible with the following formats; AIFF, WAV, ALAC, MP3, WMA, AAC, and FLAC. Additional storage is available via optional microSD card. The built-in rechargeable battery offers up to 30 hours of high-resolution playback (FLAC 96 kHz/24-bit) and 33 hours of MP3 playback (128 kbps). The Walkman ships with a USB cable and a leather case.

Gold-Plated, Oxygen-Free Copper Chassis Design: The Signature Series Hi-Res Walkman is fully encased in a high-grade gold-plated oxygen-free copper chassis. Widely used in instrument manufacturing, the copper lends the player its unique natural, acoustic sound. Its conductivity and raw strength reinforce the Walkman with impressive audio performance.

Supports a Variety of Audio Formats: Practically every Hi-Res file format has met its match with 32-bit 384 kHz PCM bit-to-bit playback and Native DSD support up to 11.2 MHz. Whatever the acronym - from PCM to DSD and beyond - the Sony Signature Series Hi-Res Walkman is prepared to play it.

Expanded Compatibility with Headphones: The Signature Series Hi-Res Walkman features the new JEITA stereo balanced headphone jack and supports balanced (4.4mm) and unbalanced (6.3mm, 3.5mm) connections for maximum sound performance and increased output.

Engineered with 4-Wire Braided Kimber Kable: Made using advanced braiding techniques, the four wire braided cables engineered with KIMBER KABLE are handcrafted to seamlessly handle high power and deliver ultimate sound performance.

Expanded Memory: The Signature Series Hi-Res Walkman packs in 256GB of built-in file memory, so that you never run out of music. Plus, never run out of space for your music library and store files in the highest quality with the microSD slot.

Hours of High-Resolution Playback: Keep the music playing as long as you are, with up to 33 hours of non-stop High-Resolution Audio playback.

Touchscreen: The fully responsive touchscreen and classic interface design have been tailored to meet the needs of the most passionate audiophiles. Simple side-key control enables you to control your music with ease.

Hi-Res Quality Bluetooth Wireless Sound: The Sony Bluetooth LDAC codec takes your music streaming to a new level. With 3x that data transmitted, LDAC provides and enhanced wireless listening experience with near Hi-Res quality.

Upscaling of Compressed Files: The DSEE HX builds on our proprietary DSEE technology, upscaling compressed audio files to a level that's closer to High-Resolution Audio. By restoring the subtleties of the original recording that are lost during the compression process, DSEE HX delivers a rich, studio-quality audio experience for all your music.

High Quality Precision Clock: Timing jitter degrades the digital audio signal, creating an unevenness and introduces distortion into the sound. A large, low-phase noise oscillator precision clock provides a timing signal to all the parts of the digital audio system, so each process can be triggered at the right moment.
