Colors in harmony The new h.ear range comes in colors to suit your lifestyle perfectly . The tones work with a spectrum of hues and different colors. Try them with your favorite outfit and it all just works in effortless harmony.

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, the 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 absolutely minimal 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.

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 in higher-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 cancelation reduces the ambient noise you would normally hear from your surroundings. Microphones built in to the headphones work with the digital noise cancelation engine to cut out unwanted sound.

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. Whether you're at home or in the office, in a coffee shop or commuting, you can enjoy premium sound quality.

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. Favorite tracks will benefit from digital to audio conversion and DSEE HX upscaling, as well as Vinyl Processor and equalizer.

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.

Store even more music with the microSD card slot Expand the already large memory of your NW-A50 with a microSD card-pop one in the slot to enjoy endless playlists and even the biggest music collections on the go.

Vinyl Processor Give the warmth and character of vinyl back to your digital tracks, and get lost again in the richness of the melodies and dynamics of your favorite albums. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise to deliver an authentic listening experience.

A choice of equalizer 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 equalizer presets. Or use the Custom levels to create your own equalizer sound.

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 favorite tracks in the way you want to by using the options on the playback screen to easily create and name playlists.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
