Key Features
Rigid aluminium milled frame
A rigid premium aluminium milled frame provides superior rigidity for low impedance and clear, stable sound and solid bass.
Evolved buttons
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.
Stylish curved design
With a premium, curved aluminium body, the NW-A50 is ergonomic to hold and fits in the palm of your hand.
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.
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.
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.
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.
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.
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.
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.
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.
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
