  • Colours in harmony.The new h.ear range comes in colours to suit your lifestyle perfectly.The tones work with a spectrum of hues and different colours. Try them with your favourite outfit and it all just works – effortless harmony.

  • 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.

  • 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. 

  • 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.

  • Digital noise cancelling for fewer distractions. When used with compatible IER-NW500N/NE headphones, the NW-A50 Series' digital noise cancelling reduces the ambient noise you would normally hear from your surroundings. Microphones built in to the headphones work with the digital noise cancelling engine to cut out unwanted sound.

  • 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.

  • Vinyl Processor. 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.

  • 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.

  • 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.

  • 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.
