Sony / NW-WM1ZM3

Sony’s “NW-WM1ZM3” is a flagship Walkman featuring a gold-plated, high-purity oxygen-free copper chassis. It is equipped with an S-Master HX digital amplifier, two large-capacity solid polymer capacitors, and a 5.5-inch display. The device supports high-resolution audio playback for up to 33 hours via a balanced connection, and offers Wi-Fi connectivity and compatibility with Android apps.

■ High-precision machined, gold-plated oxygen-free copper (OFC) chassis with a direct-coupling structure
・ The main chassis is crafted from 99.99% pure (4N) oxygen-free copper (OFC), while the rear chassis uses 99.6% pure oxygen-free copper—both finished with a direct gold-plating process. A direct-coupling structure, in which both chassis components are secured using low-resistance, gold-plated screws, enhances ground stability. This design delivers a transparent sound, powerful bass, an expansive soundstage, and smooth, beautifully extended mid-to-high frequencies.

■ "S-Master HX" for faithful reproduction of the original sound, featuring three types of "look-ahead" noise shapers
・ Equipped with the "S-Master HX" digital amplifier—developed exclusively for the Walkman—this system supports native DSD format playback and enables both balanced output and high-power output. It also incorporates a "look-ahead" noise shaper (with three selectable modes) that predicts and controls quantization noise, resulting in a powerful, dynamic bass that responds rapidly to changes in the music, alongside a clear, precise response.

■ Two high-capacity solid-polymer capacitors, inheriting the power supply philosophy of the DMP-Z1
・ Featuring two high-capacity solid-polymer capacitors designed to handle rapid fluctuations in power demand. Drawing from the power supply philosophy of the DMP-Z1, dedicated capacitors are assigned to the digital and audio circuits respectively. By absorbing digital circuit noise locally, the design prevents interference with the audio circuitry, ensuring tight, well-defined bass and vocals with a lifelike, tangible presence.

■ Power supply design for instantaneous energy delivery, featuring meticulous hand-soldered OFC wiring
・ Carefully selected components, including large-capacity solid-polymer capacitors, ensure a stable power supply, enabling instantaneous energy delivery and a rich, expansive dynamic range. By paying meticulous attention to every detail—such as using hand-soldered OFC (oxygen-free copper) wiring—the device delivers powerful, tight bass, exceptional resolution, and an expansive, immersive soundstage.

■ Large 5.5-inch High-Definition Display and Long-Lasting Battery (Up to 33 Hours)
・ Equipped with a large, high-definition 5.5-inch touch display, the device offers excellent visibility and intuitive, smooth operation. Its long-life battery supports up to 33 hours of continuous high-resolution playback (96kHz FLAC) while maintaining superior sound quality (*using the music player app, with a balanced connection).

■ Wi-Fi Connectivity and Seamless Streaming via Android Apps
・ With built-in Wi-Fi and an Android-based platform, you can access a wide range of apps. From your favorite streaming services to downloading your personal music library, you can enjoy diverse musical content with high-quality sound, exactly the way you want.

■ A Premium Design Rooted in Tradition, Featuring Sony’s Proprietary Audio Processing
・ The design—which carries on the iconic headphone jack and side-button layout of the WM1 series—is combined with carefully selected acoustic components, offering both a premium user experience and a sophisticated, distinguished aesthetic. Furthermore, Sony’s proprietary audio processing technologies bring out the full potential of various music sources and genres.
