Upgraded Components for an Enhanced Sound

Sony has've upgraded many of the internal components so that the ZX700 series now has components you’d expect from the highest-grade player, to give it a dramatic evolution in sound quality.

Large Solid High Polymer Capacitor

Adopted as battery assist for the amplifier block, the newly developed large solid high polymer capacitor offers large capacitance and low resistance. Able to instantaneously supply large amounts of power, it can accurately output signals by preventing sudden falls in voltage. This contributes to clear, powerful and accurate bass sound, as well as clear vocals.

FT CAP3 (High Polymer Capacitor)

Custom-made for Sony and tuned by Sony engineers, FT CAP3 is adopted for all bypass capacitors in the audio block power supply. Drawing on know-how cultivated in high-end home audio development, they help to improve sound expression and create a smoother sound, with a wider sound space, more transparency, and tighter bass.

Large Coil for Balanced Output

To supply the optimum balanced output signal from the digital amp, a larger, 8mm coil is used as the L-C filter. By incorporating flat conductive wire, Sony has've achieved lower distortion and lower resistance, which creates an improved sound resolution across all frequencies.

OFC (Oxygen-Free Copper) Milled Block

An OFC (Oxygen-Free Copper) milled block covers the digital block, helping both to strengthen digital ground and improve noise shielding from digital block elements such as the application processor and memory devices. The result is a clearer sound that appears to rise up from silence.

Faithful Sound Reproduction

S-Master™ HX digital amp technology, independently developed for Walkman®, is compatible with the Native DSD format and supports balanced and high-power output. It reduces distortion and noise across a wide range of frequencies, for rich and full-bodied sound, further enhanced by new high-quality sound lead-free solder.

Film Capacitors

High-quality film capacitors deliver voltage with a linear response across frequencies, resulting in reduced distortion and noise.

High Polymer Capacitors

The high polymer capacitors within the NW-ZX707 used to strengthen the power supply of the am unbalanced output, enhancing low-range reperformance for a more expansive listening experience.

OFC Cable

The low-resistance Oxygen-Free Copper (OFC) cable is used for internal headphone connection, offering low distortion and superior channel separation.

Optimized Circuit Board Layout

By dividing the Audio block (highlighted in red) and the Power/Digital block (in blue), the circuit board layout has been optimized to ensure sound quality is unaffected by digital interference.

Balanced Connection

The ZX700 series features a balanced single plug, designed for the Ø4.4mm balanced connection cable. This separates left and right sound signals, while minimizing signal transmission loss and resulting sound deterioration.

Sound Processing

Sony's unique sound processing technology gives you more ways to enjoy more different types of music than ever before.

Long Battery Life

With a long battery life, you can immerse yourself in more of your music, with up to 25 Hours of 44.1kHz FLAC playback, up to 23 Hours of 96kHz FLAC High-Resolution Audio playback, or up to 22 hours with music apps.

Premium Design

The milled aluminum frame and clear 5.0" (diag.) screen give the ZX700 series an elegant feel, while remaining small enough to be completely portable.

Distinctive Rear Section

The inclusion of larger audio parts to enhance sound quality is evident in the distinctive rear section.

Analog Style

The volume UI on the ZX700 series echoes classic analog design – a nice little detail to further enhance your listening enjoyment.

Hi-Res Audio Wireless

Enjoy High-Resolution Audio quality without wires thanks to LDAC, Sony's premium wireless codec. With 3x the bitrate of standard Bluetooth® technology, you can enjoy a superior listening experience for all your music.

360 Reality Audio

Immerse yourself in sound all around you. As real as if you were there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real.

USB Type-C™ Port

Bluetooth® and aptX™ HD

Connect wirelessly with Bluetooth and you’re ready to go. aptX™ HD audio compatibility is available.

DSEE Ultimate

Using Edge-AI (Artificial Intelligence), DSEE Ultimate™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. And the evolving algorithm now delivers even greater benefits for CD-quality (16 bit 44.1/48kHz) lossless codec audio. Restoring acoustic subtleties and dynamic range, it provides a richer, more complete listening experience.

Vinyl Processor

Give the warmth and character of vinyl back to your digital tracks. Enjoy subtle reproduction of the low-frequency resonance, tone-arm resistance and surface noise to deliver an authentic listening experience.

DC Phase Linearizer

Sony's DC Phase Linearizer works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match the phase characteristics of various types of analog amplifier to deliver a purer, more analog-like sound. Choose from six-phase character settings.

Sound great but compatibility to improve
I upgraded from F886, ZX700 sound great on both 3.5mm and 4.4mm headphone jack with my Shure se846.

It would be great if the combability can improve with iPhone. Although, ZX700 is android based, can easily install streaming apps, I would appreciate if it can serve as DAC for iphone. I have tried the DAC mode with my iPad Pro with USB-C port, it work fine. Unfortunately, when I plug-in the lightning otg cable with my iPhone 13 Pro Max / iPhone 11 Pro Max, my iPhone showed that ZX700 uses too much power. I have look for any setting to solve this, seems no options for ZX700 not charging from the iPhone connected.

I have asked the professional portable audio gear stores, some other clients have the same problem and cannot resolve. This combability issue is not purely Sony's problem, but I hope option for "not charging from connected device" would available when connected to iPhone as well, or some other ways to solve this problem in coming update.

Upgrade Necessity
No other Sony portable audio matches the fidelity of this one, especially while using the Sony XBA-Z5 earbuds(modified). Looking ahead,and from purchasing music on line, I can see how expensive adding music becomes over time. I figure the next logical step is to subscribe (for a monthly fee) --- while still using the Micro-SD card for back-up, is to go with Pandora or SXM (Sirius), maybe any reliable streaming service that can absolutely be counted on for 100% guaranteed connectivity --- A MUST at $10 -11 month.

Enjoyable & High Quality Music Player
I am again grateful to Sony for releasing this product. It's an enjoyable experience. I had the NW ZX-507 previously but the larger screen & updated form factor of the NW-ZX707 make it feel like more than just an upgrade to that player but in a different class.

I do not use IEMs, I use headphones. I tried this with the Sony MDR-H600A (Wired to 4.4MM Balanced - Sounds great), the Sony MDR-Z7M2 (Wired to 4.4MM Balanced, these are 70MM - required about 90 on the volume but it works with this device). Master & Dynamic MW65's on Bluetooth. With all of those, this device sounds excellent. Tried a few genres, Jazz, vocal & EDM genres. I would like to see in a software update a few DSPs (or at least presets for the equalizer)

Battery Life
I can't imagine getting the full 20 hours, but in the 12 days since I've had this I haven't run out of battery during the day. What I have seen is that using the 3rd party music app (i.e. Youtube Music / Spotify) will use more battery than the stock music app. There is a setting to restrict background operations because if you install 3rd party apps then those could consume battery.

I like the screen when playing Youtube music, it looks good. You can't compare it to a phone because it has it's own look.

It's a bigger/heavier device than a smartphone. Feels solid.

This is for someone who wants a dedicated music device & has a collection of HiRes music or uses a HiRes streaming service such as Qobuz. I personally have owned devices from other manufactures & would recommend Sony because it just works better. An example would be how a competitor's device's WiFI was slow because it did not work with 5G or how their bluetooth didn't have enough distance. These are things that just work correctly on the Sony players.

Best player I have owned so far
A mid-high tier DAP which checks all the boxes in terms of sound reproduction, battery life and aesthetics. I have owned Sony's older players (ZX1, WM1A, ZX507, A105) but the ZX707 is a pleasure to use even during my commutes and travel.
