Sony NW-ZX707 Walkman Hi-Res Audio WALKMAN ZX Series 64GB
Release date: January 27, 2023

High-end streaming WALKMAN that inherits the technology of the flagship model and achieves further evolution

ZX series inherits the technology of the flagship model and achieves further evolution
The ZX series has realized high sound quality that goes beyond the conventional ZX model by fully utilizing the flagship model's high sound quality technology cultivated up to now. An aluminum machined chassis and oxygen-free copper machined block are used inside. For further power supply reinforcement, large-capacity solid polymer capacitors are installed in FTCAP3 and the main power supply. Furthermore, by inheriting various high-quality sound parts, such as the use of high-quality solder with gold added to the reflow solder section, sound transparency, expressiveness, sound expansion, and bass power are further improved

S-Master HX" high-performance full digital amplifier for high-resolution playback
Supports DSD native playback (up to 11.2MHz) and linear PCM playback (up to 384kHz/32bit). It also delivers a practical maximum output of 50mW + 50mW (16Ω) for unbalanced connection and 230mW + 230mW (16Ω) for balanced connection. High sound quality that maintains detail from low to high volume is realized, and along with the powerful sense of energy and speed of bass, even the subtle sense of air is reproduced realistically. (Not valid for wireless listening (Bluetooth (R) connection).

Acoustic processing that can only be achieved with a dedicated music player
The SD Remastering Engine uses Sony's proprietary algorithms to convert all PCM sound sources into a DSD signal equivalent to 11.2 MHz without losing the information content of the original data. DSEE Ultimate, which uses AI (Artificial Intelligence) technology that learns from a vast amount of music data, analyzes the scene of the music in real time and optimally upscales the sound to high-resolution level quality. DSD native playback is supported only with a balanced connection. DSD native playback is supported only with a balanced connection; with an unbalanced connection, playback is converted to linear PCM. When "DSEE Ultimate" is turned on for both wired and wireless connections (extended up to 192kHz/32bit); when connected wirelessly (Bluetooth(R)) using the LDAC codec, playback is possible at up to 96kHz/24bit.

Improved battery life by adopting a new platform
The new platform has realized power saving. In particular, power consumption in standby mode and when using music streaming services has been greatly reduced.

Stylish new design and usability that pursues comfort as a dedicated music device
The 5.0-inch display and music playback-specific UI make it possible to select songs and operate the device more smoothly. In addition, the new stylish design with a luxurious feel allows users to enjoy high-quality sound even when they are out and about.

Balanced output for complete left/right sound separation
Balanced output completely separates left and right signals, allowing sound signals to be output without grounding. Crosstalk (interference between left and right signals), which adversely affects stereo perception, is reduced to the absolute minimum, reproducing low distortion and delicate sound with little noise.

High rigidity and low impedance with machined aluminum housing
The combination of an aluminum machined housing with excellent rigidity and oxygen-free copper plates has realized a significant reduction in impedance. This enables clear and powerful low-frequency reproduction.
