Sony WM1AM2 Walkman Digital Media Player - NWWM1AM2

Model #:NWWM1AM2

Aluminium frame

An aluminum-alloy frame provides a highly rigid case that’s resistive to electrical noise and other interference for stable, high-quality sound.

Faithful sound reproduction

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.

An even stronger power supply

The WM1AM2 boasts an even stronger power supply than its predecessor, not only in the analogue block but also in the digital block—an idea inspired by our flagship digital music player, the DMP-Z1.

Large, solid high-polymer capacitor

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 clear, powerful and accurate bass sound, as well as clear vocals.

FT CAP3 (High-polymer capacitor)

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.

OFC milled block

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.

High-polymer capacitors

The high-polymer capacitors within the WM1AM2 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.

Film capacitors

High quality film capacitors deliver voltage with a linear response across frequencies, resulting in reduced distortion and noise.

Winding inductors

Replacing the conventional laminated capacitor, winding inductors in the digital block power supply contribute to a pure sound. 

Oxygen-free copper cable

A low-resistance oxygen-free copper (OFC) cable offers low distortion and superior channel separation.

Crystal oscillators

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 realize clear, open sound reproduction.

Fine Sound Register

The surface mounted Fine Sound Register ensures even, effective distribution of power to the circuit components, for consistent sound quality.

Newly developed reflow solder containing gold

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 localization and a wider sound space.

High-quality solder containing gold

The exceptional conductivity of gold ensures absolutely minimal 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 WM1AM2 to the battery.

Low dielectric circuit board and filled via

The printed circuit board uses low dielectric material to realize 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

Optimized circuit board layout

By dividing the Audio block and the Power/Digital block, the circuit board layout has been optimized to ensure sound quality is unaffected by digital interference.

DSD Remastering Engine

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.

DSEE Ultimate

Using Edge-AI (Artificial Intelligence), DSEE Ultimate™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. And the evolving algorithm now delivers even greater benefits for CD-quality (16bit 44.1/48kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range, it provides a richer, more complete listening experience.

Vinyl Processor

Give the warmth and character of vinyl back to your digital tracks. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise to deliver an authentic listening experience.

DC Phase Linearizer

Our DC Phase Linearizer works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match the phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound. Choose from six phase character settings.

Balanced connection

The Walkman® features a balanced single plug, designed for the Ø4.4 mm balanced connection cable. This separates left and right sound signals, while minimizing signal transmission loss and resulting sound deterioration. 

Every note as the artist intended

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/96 kHz and beyond), High-Resolution Audio allows you to get closer to the original studio recording.

11.2 MHz DSD Native/PCM 384 kHz

Supreme quality with 11.2 MHz DSD native using balanced headphones and PCM 384 KHz/32-bit support.

Hi-Res Audio Wireless

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.

For the discerning music listener

With its aluminum body, twin headphone jacks, and large 5.0‑in screen, the WM1AM2 has a high-end look and feel—so wherever you go, your music travels in style.

Distinctive rear section

The machine-carved aluminum rear frame offers high rigidity, contributing to clear, transparent sound reproduction. The inclusion of larger audio parts to enhance sound quality is evident in the distinctive rear section, which is noticeably thicker than its predecessor.

Analogue style

The volume UI on the WM1AM2 echoes classic analogue design—a nice little detail to further enhance your listening enjoyment. 

Wi-Fi lets you stream and download even more music

Supported by Android™ and compatible with Wi-Fi, the WM1AM2 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.

Large 5.0‑in display

Smooth and responsive, the large 5.0‑in (12.7-cm) touchscreen display has been enlarged from its predecessor’s 4.0‑in (10.2-cm) display and upgraded to HD.

Long battery life

Immerse yourself in your music with up to 40 hours of non-stop 96 kHz FLAC High-Resolution Audio playback.

Walkman® Home Screen

With the Walkman® Home Screen, you can customize the home display to suit your needs.
