SONY / NW-ZX707

The ZX series, SONY / NW-ZX707, inherits the technology of the flagship model and has further evolved. We have generously introduced high-quality technology to achieve high-quality sound that goes beyond the conventional ZX.

■The ZX series inherits the technology of the flagship model and has achieved further evolution.
・We have generously applied the flagship high-quality technology that we have cultivated to date, achieving high-quality sound that goes beyond the conventional ZX. An oxygen-free copper cutting block is used for the aluminum cutting casing and inside. Equipped with a large-capacity solid polymer capacitor in the FTCAP3 and main power source for further power enhancement. Furthermore, by inheriting various high-quality sound parts, such as using high-quality solder with gold added to the reflow solder parts, the clarity, expressiveness, spaciousness of the sound, and the strength of the bass have been further improved. We strived to create a sense of realism and presence as if you were listening to a live performance right in front of your eyes.

■Supports DSD native playback (up to 11.2MHz) (*2) and high output
・Supports DSD native playback (up to 11.2MHz) and linear PCM playback (up to 384kHz/32bit). In addition, the maximum practical output is 50mW + 50mW (16Ω) when unbalanced and 230mW + 230mW (16Ω) when balanced. Achieving high sound quality that maintains details from low volumes to high volumes, realistically reproducing the powerful bass energy and speed, as well as the delicate atmosphere. You can experience it with a thrilling sense of reality.

■Equipped with the sound processing unique to a dedicated music device: “DSD Remastering Engine” and “DSEE Ultimate”
- Equipped with a DSD remastering engine that uses Sony's proprietary algorithm to convert all PCM sound sources to DSD signals equivalent to 11.2MHz without losing the amount of information in the original data (*1). In addition, it is equipped with ""DSEE Ultimate,"" which uses AI (artificial intelligence) technology that learns a huge amount of song data to analyze the scene of the song in real time and upscale it to optimal high-resolution (*2) high-quality sound. Expand the bits and increase the sampling frequency to a maximum of 192kHz/32bit equivalent. Using AI technology, it automatically identifies songs and improves the reproduction of minute sounds. The evolution of the AI algorithm has also improved the upscaling performance of CD-quality sound sources (44.1kHz and 48kHz/16bit). In addition to being connected via wired connection or using the W.Music app, it is also compatible when connecting wirelessly or using a streaming service. You can enjoy all kinds of sound sources with high-resolution (*2) high-quality sound that reproduces minute sounds.

■Improved battery life by adopting a new platform
- Achieved power savings by adopting a new platform. In particular, power consumption during standby and when using music streaming services is greatly reduced. Continuous playback is possible for up to 25 hours (*1) when using the music playback app ""W. Music"" and up to 22 hours (*2) when using the music streaming service app (offline mode). As a dedicated music device, we strive for battery performance that allows for comfortable and long music playback.

■Usability and stylish new design pursue comfort as a dedicated music device
・In pursuit of comfort as a dedicated music device, the adoption of a 5.0-inch display and a UI specialized for music playback make it possible to perform operations such as selecting songs more smoothly. What's more, the new, luxurious and stylish design allows you to enjoy high-quality sound even when you're out and about.
Also, with Android (TM) 12.0 installed, you can download various apps from the Google Play (TM) store. It also supports high-resolution streaming, so even when using a streaming service that provides high-resolution music, you can play it with the high sound quality that only a dedicated music device can provide. You can enjoy the artist's breathing and the vividness of the instruments.
