Take music to the next level with the incredible fidelity of High-Resolution Audio and colours to suit your lifestyle. The NW-A55 is made with precision engineering and quality parts such as a rigid aluminium milled frame and audio-grade lead-free circuit soldering spiked with gold, for crystal clear sound. Improved DSEE HX restores compressed audio files, and you can stream over BLUETOOTH® with LDAC to preserve the detail in every track.
High-Resolution Audio compatible
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..
Premium, audio-grade lead-free solder containing gold
For clearer sound and vocals, new high-quality lead-free solder with a small amount of gold is used to connect the circuit of the NW-A50 to the battery. The exceptional conductivity of gold ensures absolute minimum signal loss.
Control your music with ease, through the intuitive side key buttons of the NW-A50. The play/pause, music-selection and volume buttons on the side panel are shaped and positioned for easy operation, even by feel alone.
USB DAC function makes music played from your computer sound even better
Use your NW-A50 Series as a USB DAC (Digital-Analogue Converter) by pairing it with a PC or Mac computer. When connected and activated using the supplied USB cable, the NW-A50 Series replaces your computer’s regular sound processing with its own, highly-tuned, hardware processing. Now, whether you’re at your home or office, in a coffee shop or commuting, you can always enjoy premium sound quality.
Store even more music with the SD card slot
Expand the already large memory of your NW-A50 with an SD card – pop one in the slot to enjoy endless playlists and even the biggest music collections on the go.
New DSEE HX AI analyses song type
Audio upscaling is improved even further by our new DSEE HX processor which intelligently recognises instrumentation and musical genres. Realism and liveliness of different instruments, including the human voice, are inherently characterised by high frequency harmonics. By identifying instruments, and the relative energy of the audio, our enhanced DSEE HX can accurately rebuild audio lost during digital compression, for a full fidelity experience even with heavily-compressed audio formats.
Rigid aluminium milled frame
A rigid premium aluminium milled frame provides superior rigidity for low impedance and clear, stable sound and solid bass.
NFC™ One-touch for instant connectivity
Near Field Communication (NFC™) and BLUETOOTH® technology make connecting to your music fast and easy. Just touch your NFC™-enabled device to your NW-A50 Series for a quick, seamless connection, then start streaming.
Listen for longer with up to 45 hours' battery life
Perfect for commuting or when you want to enjoy your music all day, when fully charged you can enjoy up to 45 hours of music playback.
Playback screen and playlist naming within the UI
The intuitive UI of the NW-A50 lets you play, search, fast forward and repeat easily and seamlessly. Listen to your favourite tracks in the way you want to by using the options on the playback screen to easily create and name playlists.
S-Master HX™ delivers High-Resolution audio in maximum quality
Optimised for High-Resolution Audio, S-Master HX™ amplifier reduces distortion and noise, allowing you to enjoy all the subtleties in your music.
Circuit board with gold-plate for powerful bass
The NW-A50 has onboard plate and contact springs which directly connect the circuit board and aluminum milled frame, and they’re both plated with gold. The results are powerful bass and a clear mid-range.
Stylish curved design
With a premium, curved aluminium body, the NW-A50 is ergonomic to hold and fits in the palm of your hand.
LDAC™: for the transmission of High-Resolution Audio content
Enjoy your music at greater than CD quality with LDAC™ wireless audio transmission. LDAC uses a conventional BLUETOOTH® connection, but transfers at a maximum data transfer rate up to 990kbps – approximately three times that of other audio profiles. The result is enhanced wireless listening that's much closer to the artist's intention.
Give back the warmth and character of vinyl to your digital tracks and get lost again in the richness of the melodies and dynamics of your favourite albums. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise deliver an authentic listening experience.
A choice of equaliser presets and custom levels
For authentic tone and sound that matches the music category you’re listening to, the NW-A50 has a choice of equaliser presets. Or use the Custom levels to create your own equaliser sound.
BLUETOOTH® Receiver mode to give your smartphone music a boost
Stream music through the NW-A50 via Bluetooth® and a smartphone connection and give all your music an NW-A50 boost. Favourite tracks will benefit from S-Master HX™ and DSEE HX upscaling, as well as Vinyl Processor and equaliser.
