One Signature Sound
Elevating the high-resolution sound experience from one you listen to, to one you can feel.
Despite oxygen-free copper (OFC) being notoriously difficult to machine process, the WM1ZM2 features a gold-plated OFC chassis – just like its predecessor. This time though, OFC purity has been upgraded to 99.99% (four nines), offering even greater benefits in terms of audio quality and high rigidity. Bass notes are clear and powerful, the atmosphere is more expansive, and mid to high range sounds linger beautifully.
S-Master™ HX digital amp technology, independently developed for Walkman®, is compatible with the Native DSD format, and supports balanced and high power output. It reduces distortion and noise across a wide range of frequencies, for rich and full-bodied sound, further enhanced by new high quality sound lead-free solder.
Taking inspiration from the DMP-Z1, our flagship digital music player, the WM1ZM2 features an even stronger power supply than its predecessor, both in the analog block and the digital block.
Adopted as battery assist for the amplifier block, the newly developed large solid high polymer capacitor offers large capacitance and low resistance. Able to instantaneously supply large amounts of power, it can accurately output signals by preventing sudden falls in voltage. This contributes to powerful and accurate bass sound, as well as clear vocals.
Custom-made for Sony and tuned by Sony engineers, FT CAP3 is adopted for all bypass capacitors in the audio block power supply. Drawing on know-how cultivated in high-end home audio development, it has helped to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.
An OFC milled block covers the digital block, helping both to strengthen digital ground and improve noise shielding from digital block elements such as the application processor and memory devices. The result is a clearer sound that appears to rise up from silence.
The high polymer capacitors within the WM1ZM2 are used to strengthen the power supply of the amp block for unbalanced output, enhancing low-range reproduction performance for a more expansive listening experience.
Replacing the conventional laminated capacitor, winding inductors in the digital block power supply contribute to a pure sound.
To achieve the evolution in sound quality on the WM1ZM2 we not only upgraded a number of parts but also assembled them in the best possible layout.
The wiring material from the amp base to the balanced headphone jack has been upgraded to thick KIMBER KABLE®, just like on the flagship DMP-Z1 music player. This helps to shut out external noise, transmit high quality audio signals, and achieve powerful and smooth sound quality.
Two compact low-phase-noise crystal oscillators ensure precision clock stability at sampling rate multiples of 44.1kHz and 48kHz. The crystal electrode piece is formed with gold vapour deposition for enhanced electric characteristics and improved instrumental separation. This helps remove a veil and reduce noise to realise clear, open sound reproduction.
The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.
This is the first time Sony has used reflow solder containing gold, and it features extensively across the circuit board surface – so the overall effect is significant, including improved sound localisation and a wider sound space.
The exceptional conductivity of gold ensures absolute minimum signal loss. For clearer sound and vocals, a premium, audio-grade lead-free solder with a small amount of gold connects the circuit of the WM1ZM2 to the battery.
The printed circuit board uses low dielectric material to realise accurate signal transmission, while the via holes are filled with copper to further reduce impedance. The result is a wide sound space with clear, bright sound.[A] Normal via [B] Filled via
By dividing the Audio block (highlighted in red) and the Power/Digital block (in blue), the circuit board layout has been optimised to ensure sound quality is unaffected by digital interference.
The WM1ZM2 features a range of sound processing technologies to help you get the most out of your music, whatever the source.
PCM (Pulse Code Modulation) audio is resampled into an 11.2MHz DSD (Direct Stream Digital) ultra-high-frequency 1-bit audio stream. The single-bit stream delivered to the DAC has a character far closer to that of analogue, giving you even more ways to enjoy your music.
The Walkman® features a balanced single plug, designed for the Ø4.4mm balanced connection cable. This separates left and right sound signals, while minimising signal transmission loss and resulting sound deterioration.
Take your digital music collection to another level with High-Resolution Audio. By capturing and reproducing digital audio at a higher rate than CD (24-bit/96kHz and beyond), High-Resolution Audio allows you to get closer to the original studio recording.
Supreme quality with 11.2MHz DSD native using balanced headphones and PCM 384KHz/32-bit support.
Enjoy High-Resolution Audio quality without wires thanks to LDAC, our premium wireless codec. With 3x the bitrate of standard BLUETOOTH® technology, you can enjoy a superior listening experience for all your music.
The Walkman includes MQA technology, which enables you to play back MQA audio files.
Equipped with a bigger display and featuring larger audio components, the WM1ZM2 balances functionality with iconic style.
Key design elements include the twin headphone jacks on the top and the intuitive side key, both inherited from its predecessor.
Supported by Android™ and compatible with Wi-Fi, the WM1ZM2 gives you even more freedom to enjoy music. Listen to your favourite streaming and music apps on your Walkman or connect to a PC to download tracks and playlists from your music collection.
Smooth and responsive, the large 5.0” (12.7cm) touchscreen display has been enlarged from its predecessor’s 4.0” (10.2cm) display and upgraded to HD.
Immerse yourself in your music with up to 40 hours of non-stop 96kHz FLAC High-Resolution Audio playback.
With the Walkman® Home Screen, you can customise the home display to suit your needs.
A USB Type-C® port, compatible with USB 3.2 Gen1, offers fast music file transfer and easy connectivity with a range of devices.
With 256GB integrated memory and an SD card slot, the WM1ZM2 lets you take even the biggest music collections on the go.
Immerse yourself in sound all around you. As real as if you are there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real. The WM1ZM2 lets you enjoy 360 Reality Audio.
Our products are not only designed to be stylish but also with the environment in mind. No plastic is used in the packaging material for the WM1ZM2, reflecting Sony’s commitment to reducing the environmental impact of our products and practices.
