Hear your colours
Bring harmony into your life with the colours of the h.ear range. Available in five unique shades, each one fits seamlessly with your style and your world.

Find your style. Step up your sound.
With a premium handy design, the NW-A50 delivers the incredible fidelity of High-Resolution Audio, plus audio upscaling with enhanced DSEE HX and vinyl processor.

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.

Truly authentic sound with High-Resolution Audio
Feel as if the artist is performing right in front of you with higher-than-CD quality High-Resolution Audio, which faithfully reproduces even the subtlest nuances of studio-quality sound.

DSD playback
Experience the natural sound and intense detail of DSD audio formats, thanks to the NW-A50 Series' high-quality PCM conversion.

Audio upscaling with new DSEE HX
Bring even heavily-compressed audio formats back to a full fidelity experience with our advanced DSEE HX processor, which uses AI to accurately analyse song type, instrumentation and musical genres.

S-Master HX™ optimised for High-Resolution Audio
Enjoy all the subtleties in your music with S-Master HX™ which delivers High-Resolution Audio in maximum quality, with reduced distortion and noise.

Rigid aluminium milled frame for improved sound quality
The premium aluminium milled frame provides superior rigidity for low impedance and clear, stable sound and solid bass.

Advanced solder containing gold for clearer sound
The exceptional conductivity of gold ensures absolute minimum 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 NW-A50 to the battery.

Gold plated circuit board and contact springs for low impedance
The onboard plate and contact springs of the NW-A50 that connect the circuit board to the aluminium milled frame are both plated with gold. The results are powerful bass and a clear mid-range.

Stylish curved design, evolved buttons
Ergonomic to hold, with a premium, curved aluminium body, the NW-A50 fits in the palm of your hand. Intuitive side key buttons let you control your music with ease. The play/pause, music-selection and volume buttons on the side panel are shaped and positioned for easy operation, even by feel alone.

Better BLUETOOTH® streaming
LDAC™ uses a conventional BLUETOOTH® connection, but transfers at a maximum data transfer rate of 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. Full aptX™ HD audio compatibility is available with a firmware update.

Noise cancelling quietens external sounds
Want to be alone with your tunes? Activate noise cancelling, and the compatible IER-NW500N/NE headphones work with the NW-A50 Series to block out external sounds.

Ambient Sound mode lets essential audio in
When you're using the compatible IER-NW500N/NE headphones, activate Ambient Sound mode and you'll hear external sounds along with your music.

Music played from your computer sounds even better with USB DAC function
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.

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.
