Sony NW-ZX707 Walkman® High-resolution portable digital music player with Wi-Fi® and Bluetooth®

Features

Overview: The Sony NW-ZX707 is a Walkman ZX-series digital music player, capable of playing high-resolution audio files up to 32-bit / 384kHz. The NW-ZX707 has Wi-Fi for direct downloads, and Bluetooth Audio Streaming. The device is equipped with balanced (4.4mm) and unbalanced (3.5mm) outputs for headphones. The unit features a 5.0" high-definition LCD screen, and an internal 64 GB flash memory. You can add even more memory by inserting an optional microSD card.

Supported Audio Formats: The NW-ZX707 Hi-Res Walkman can support multiple digital audio formats:

Construction: The NW-ZX707 is precision-engineered and constructed with high-quality materials and upgraded components for superior sound quality. It has a rigid milled aluminum frame which shields the internal circuitry from electrical noise. Internally, the NW-ZX707 uses high quality film capacitors in the amplification stage, helping the unit to deliver powerful bass and wide expansive instrumentals and vocals. The circuit board layout separates the audio block from the power/digital block to minimize digital interference that will compromise sound quality. To minimize signal loss, the circuit board also uses audio-grade, lead-free solder with a small amount of gold for optimal signal transfer.

Headphone Outputs: The ZX707 is equipped with two headphone outputs: a 4.4mm standard balanced output and a 3.5mm stereo mini output. The balanced output has an extra connection (L+, L-, R+, R-) compared to an unbalanced connection (L+, R+, Gr), which fully separates the left and right channels, which minimizes signal loss and fuller sound. The unit's digital amplifier uses a larger 8mm coil for the unit's balanced output which lowers distortion and resistance for improved sound resolution.

Side-mounted Controls: The unit has a row of physical controls along the right edge of the player. Buttons include music playback controls (play/pause, skip forward (hold down for fast forward), skip backward (hold down for fast rewind), Volume up, Volume down, and Power. A sliding Hold switch locks the playback operating buttons and volume controls to avoid accidental commands.

Display: The digital audio player has a high-definition 5.0" TFT color display (1280 x 720 pixels) with touch screen controls. The unit even features a special Cassette Tape playback screen to commemorate the Sony Walkman portable music player.

USB-DAC Function: Connecting the player to your computer via USB allows you to enjoy the digital music content on your computer with the same sound quality as the player. The computer's Digital-to-Analog Converter (DAC) is bypassed, and the Walkman's much higher quality DAC is utilized. You can use any of the player's sound adjustments to shape the sound quality of the output. There are desktop applications that are recommended for use with the USB-DAC function: Music Center for PC (Windows) and Hi-Res Audio Player for Mac (Mac). You must turn off the USB-DAC function before using the ZX707 as a music player again.

Android Operating System: The user interface of the NW-ZX707 is supported by Android 12.0. You can set up a Google Account, or use an existing account, to use services provided by Google. When connected to a Wi-Fi network, you can purchase music content, including hi-res audio, from other online music services. The Home Screen has a "dock" for displaying shortcuts. Swiping up from the bottom of the screen displays the All Apps screen. The unit features the following pre-installed apps:

• Music Player: The Music Player app lets you play music content stored on the player, either transferred from your computer or purchased from online music services.
• Sound Adjustment: This app lets you adjust the sound coming from the headphone outputs. This app is particularly useful when playing music from apps other than Music Player.
• Sony Headphones Connect: Headphones Connect is used for registering and setting up your headphones.

Memory: The NW-ZX707 has a 64 GB built-in internal memory for storing your high-resolution music files. If more storage is needed, there is a slot for an optional microSD memory card. Based on an average of 4 minutes per song, the built-in memory can hold the following number of songs:

Wi-Fi: You can connect the NW-ZX707 to a Wi-Fi network to download music to the player, stream music, and update the system software. The device works on either 2.4 GHz or 5 GHz band, and uses WEP/WPA/WPA2 encryption.

Bluetooth: With built-in Bluetooth 5.0, you can stream your music files wirelessly from compatible devices up to 30 feet away. The NW-ZX707 supports LDAC, which uses the conventional Bluetooth connection, but transfers data at up to 999 kbps. That's three times the transfer rate of other audio profiles, which results in higher fidelity. In addition, the unit supports aptX, aptX HD, AAC, and SBC.

Sound Quality Settings: You can adjust the sound quality with the following Sound Quality Settings:

• 10-band Equalizer/EQ Presets: You can adjust the sound at 10 individual EQ bands at 31Hz, 62Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz. The adjustment can be made from -10 to +10dB, and saved as Custom 1, Custom 2, or Custom 3 presets.
• DSEE Ultimate™: DSEE Ultimate uses an algorithm to analyze the music, and automatically replace the "lost" information. DSEE Ultimate (Digital Sound Enhancement Engine) gives your highly-compressed music files new life so they sound almost as good as true Hi-Res Audio quality. DSEE Ultimate can be turned on or off, as desired.
• DC Phase Linearizer: This function makes low frequency phase characteristics more similar to a traditional analog amplifier. It can be turned on/off, as desired.
• Dynamic Normalizer: The Dynamic Normalizer can moderate the change in volume between tracks to minimize the difference in volume level. It can be turned on/off , as desired.
• Vinyl Processor: The Vinyl Processor can add the character of vinyl recordings to your digital recordings with subtle reproduction of the low-frequency resonance, tone-arm resonance, and surface noise.
• DSD Remastering: This function converts a PCM signal to a DSD signal to reproduce sound quality close to analog. Can only be used when you connect headphones to the 4.4mm balanced headphone jack.

Rechargeable Battery: The NW-ZX707 has a built-in Lithium-Ion rechargeable battery for exceptional stamina. After a 3.5-hour full recharging time (via USB power), the unit's estimated battery life is as follows:

USB-C Port / System Requirements: The bottom-mounted USB-C port (USB 3.2 Gen1 compliant) lets you connect the player to your computer for charging the battery, and transferring music content (using the included USB Type A to USB-C cable), or play back the music on your computer through the USB-DAC function. Downloadable software is available for use with the NW-ZX707: Music Center for PC (Windows 11, Windows 10) or Android File Transfer for Mac (macOS 10.7 and higher).
