Battery Life — Continuous Playback Music Notes:

The values shown in this topic are the approximate battery life when content is played continuously at the default settings. Even if the player is turned off for an extended period, a small amount of battery power is still consumed. Battery life may vary depending on volume settings, conditions of use, and ambient temperature. The battery is consumed considerably when the screen is on. The battery life may become about 70% shorter when some of the sound quality settings are active.

Stylish curved design

With a premium, curved aluminum 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.

S-Master HX™ delivers High-Resolution Audio in maximum quality

Optimized for High-Resolution Audio, S-Master HX™ amplifier reduces distortion and noise, allowing you to enjoy all the subtleties in your music.

New DSEE HX AI analyzes song type

Audio upscaling is improved even further by our new DSEE HX processor which intelligently recognizes instrumentation and musical genres. Realism and liveliness of different instruments, including the human voice, are inherently characterized 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 aluminum milled frame

A rigid premium aluminum milled frame provides superior rigidity for low impedance and clear, stable sound and solid bass.

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 on-board 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.

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.

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 990 kbps — approximately three times that of other audio profiles. The result is enhanced wireless listening that's much closer to the artist's intention.

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 cancelation for fewer distractions

When used with compatible IER-NW500N/NE headphones, the NW-A50 Series' digital noise canceling reduces the ambient noise you would normally hear from your surroundings. Microphones built in to the headphones work with the digital noise-canceling engine to cut out unwanted sound.3

USB DAC function makes music played from your computer sound even better

Use your NW-A50 Series as a USB DAC (Digital-Analog 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 in the office, in a coffee shop or commuting, you can always enjoy premium sound quality.

BLUETOOTH® Receiver mode to give your smartphone music a boost
