Enjoy true DSD playback with the Sony NW-ZX300 Walkman Digital Music Player, offered here in a silver finish. This Walkman supports playback of DSD, AAC, WMA, FLAC, ALAC, and MP3 audio files. It features 64GB of internal flash memory and supports microSD cards. The NW-ZX300 also boasts a 3.1" TFT color LCD touchscreen with an 800 x 480 resolution. Its built-in rechargeable battery provides up to 30 hours of continuous audio playback on a full 5.5-hour charge.

This Walkman utilizes several audiophile-friendly technologies, including support for 1-bit DSD playback up to 11.2 MHz, as well as DSEE HX upscaling. Sony's wireless codec, LDAC, delivers a higher bit rate than standard Bluetooth, so you can enjoy an enhanced listening experience with a compatible pair of wireless headphones. You can also pair the Walkman with other compatible devices over conventional Bluetooth with NFC.

The NW-ZX300’s proprietary operating system works with Mac and Windows computers, and utilizes a simple drag-and-drop process for quickly moving songs from your computer library to the Walkman. Also, you can use the NW-ZX300 as a USB DAC, circumventing your computer’s sound card and achieving better sound in the process through the unit’s S-Master HX amplifier.

Hi-Resolution Amplifier

Optimized for High-Resolution Audio, the S-Master HX amplifier reduces distortion and noise, allowing you to enjoy all the subtleties in your music.

True DSD Playback and Support

Enjoy sound quality higher than PCM, thanks to the Direct Stream Digital audio codec, designed specifically for high-resolution audio. This 1-bit format can deliver a more natural and detailed sound. The result is clear and crisp.

DSEE HX Upscaling

DSEE HX builds on Sony's 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 aims to deliver a rich, studio-quality audio experience for all your music.

4.4mm Balanced Connection

In addition to the standard 3.5mm connection, the NW-ZX300 features a 4.4mm balanced plug, designed for Sony's balanced connection cable. This supplies compatible headphones with fully discrete left and right channels, unlike conventional headphones that share a ground wire. The result is better external noise suppression and improved stereo imaging, as well as more headroom for powerful sound delivery.

Aluminum Milled Frame

A rigid aluminum milled frame provides strong resistance to electrical noise, ensuring a clear, stable sound.

Precision-Engineered Build

The circuit board has been engineered for efficiency. The layout from the battery to the audio block minimizes the power loop, making the power supply stable. This results in a clear sound with solid low end. Other precision-engineered components include high-quality film capacitors for a linear response across frequency, lead-free solder on the circuit board and the S-Master HX chip (CXD-3778GF), resulting in an efficient electronic connection.


You can use this device as a USB DAC (digital-analog converter) by pairing it with a Mac or Windows PC. When connected and activated using the supplied USB cable, the unit replaces your computer's regular sound processing with its own hardware.

MQA Support

This device is fully compatible with MQA, furthering its functionality when it comes to lossless music.

LDAC Transmission

LDAC uses a conventional Bluetooth connection, but transfers at a maximum data transfer rate up to 990 kbps-approximately three times that of other audio profiles. The result is a wireless listening experience capable of streaming PCM files with high sample rates.

Long Battery Life

The NW-ZX300 holds enough charge for up to 30 hours of 128 kbps MP3 playback, or up to 26 hours of 96 kHz/32-bit FLAC High-Resolution Audio playback, so you don't have to worry about finding a charger when you're out and about.

Matte Glass Screen

A touch-sensitive matte glass screen allows smooth fingertip control with fewer fingerprints.

Expandable Memory

Want to store more music on your Walkman? Pop in a microSD card (available separately) for additional memory.

Handy Buttons for Quick Control

The play/pause, music selection, and volume buttons on the side panel are shaped and positioned for easy operation.
