Features
High-Resolution Audio for uncompromised sound
Experience digital music to the fullest with High-Resolution Audio. By capturing music at a higher rate than CD, increasing both audio samples per second and the bit-rate accuracy of each sample, High-Resolution Audio offers an uncompromised rendition of an artist’s music. Savour every breath and subtle movement for a truly emotional experience.
Noise canceling headphones put your music centre-stage
The NW-A20 series includes exclusive Noise canceling headphones , so you can shut out the sounds of the world around you. Choose from a number of settings, depending on your environment, and immerse yourself deeper into the music as Noise canceling offsets ambient noise, for a more engaging listening experience.
DSEE HX restores your music files
Go beyond CD quality. DSEE HX builds on our proprietary DSEE technology, upscaling compressed audio files to a level that’s closer to High-Resolution Audio. By restoring the subtleties of the original recording that are lost during the compression process, DSEE HX delivers a rich, studio-quality audio experience for all your music.
S-Master HX digital amplifier: utmost sonic purity
Enjoy the best High-Resolution Audio experience with the S-Master HX digital amplifier. Using a simplified and fully digital signal path, S-Master HX reproduces the subtleties and wide frequency range of high resolution formats. Unlike conventional amplifiers, it maintains the digital signal until right before the speaker output, eliminating distortion — for High-Resolution Audio, just as the artist intended.
ClearAudio+ enriches your music
Unique to Sony, ClearAudio+ automatically adjusts sound settings for an enriching listening experience. By bringing together expertise in digital signal processing technologies, ClearAudio+ is able to optimise audio formats to deliver a consistently clear, high-quality sound, whatever music you’re into.
Highest quality Bluetooth streaming: LDAC
Developed by Sony, the Bluetooth® LDAC codec takes your music streaming to a new level. It supports up to three times greater bitrate than typical Bluetooth® streaming. 96 kHz sampling rates and more efficient coding for CD-quality wireless sound.
One-touch listening to play instant music
NFC (Near Field Communication) technology removes the need for wired connections and complex setup sequences. Simply touch your NFC-enabled smartphone or other device* to the on-body N-mark and start your music. No NFC? No problem. You can also pair the devices manually in Bluetooth® settings. *See compatible devices
Improved battery life for longer listening
Never run out of power when you're on the move. The NW-A20 holds enough charge for up to 50 hours of MP3 playback, or up to 30 hours of High-Resolution Audio playback, so you don't have to worry about finding a charger when you're out and about.
Multiple music formats
The NW-A20 series supports High-Resolution Audio formats as well as popular formats like MP3, WAV, AIFF, WMA, AAC, HE-ACC, FLAC, and ALAC.
