Category : Wireless Speakers


Made for High-Resolution Audio

Enjoy the subtlest nuances of studio-quality sound in higher than CD quality with High-Resolution Audio. Passion for music unites every component from signal to speaker, so it feels like the artist is performing right in front of you. The NW-WM1A Walkman® also supports the very latest 384 kHz / 32-bit rate and DSD Native Playback.

Native DSD

The NW-WM1A supports native DSD audio files, which are sourced early in the production process. This means they retain all the authentic detail of the original recording.

S-Master HX

The new S-Master HX digital amp technology, independently developed for Walkman®, cuts distortion and noise across a wide range of frequencies for rich, full bodied sound.


DSEE HX upscaling technology uses an algorithm to analyze your music and replace any lost information, so that the quality is almost high-resolution level. Choose from 5 modes to bring out the best in your music. 

Incorporating the ø4.4 mm Balanced Standard Plug

Enjoy clear, precise, dynamic sound with balanced audio. With a new ø4.4 mm Balanced Standard Plug, noise picked up from the wire to the amplifier is reduced. The result—superior sound, delivered with clarity.

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.

Oxygen-free Copper cable 

A low-resistance Oxygen-free Copper cable offers low distortion and superior channel separation.

MELF resistors

Reduce noise and minimize distortion in the audio signal path with MELF type resistors. 

Streamlined power

The newly developed FT CAP (high polymer capacitor) works to regulate power flow, optimizing it for instant, clean power when needed.  

Perfect for everyday life

The NW-WM1A is designed to fit in with your everyday lifestyle. With its compact size and lightweight build, it's easy to grab when you're in need of some high quality music.
