Sony NW-ZX300

When you hold the Sony NW-ZX300 Walkman in your hand, the heft of the milled aluminum casing lets you know this is a quality portable music player. The Walkman's powerful digital-to-analog converter (DAC) renders high-resolution files in their native resolution for pristine, better-than-CD sound.

Plus, the player's USB port lets you use the built-in DAC to play high-resolution sound from your computer through your headphones. (You can download high-res tunes from sites like HDtracks).

Advanced circuitry for high-res sources

The NW-ZX300 is compatible with high-res DSD files (up to 11.2MHz), PCM-based files (up to 32-bit/384kHz), Apple Lossless, and other formats. Sony's built-in Digital Sound Enhancement Engine can help MP3 and other lossy file formats sound fuller. Pair this Walkman with a great set of headphones, and you might discover details in your favorite tunes you've not heard before.

Ample storage for high-res files

The NW-ZX300 comes with 64GB of built-in storage — enough for over 1,000 CD-resolution songs. If you need more memory the player's microSD card slot can accommodate up to a 128GB card. That gives you up to 192GB of storage.

Bluetooth® compatible for wireless listening

This player offers high-quality aptX® playback as well LDAC Hi-Fidelity wireless music streaming to compatible products. The better your headphones, the more detail you'll hear.

Advanced features for high-performance audio

The milled casing isn't just for looks — the aluminum shields the player's circuitry from electrical noise. High-quality film capacitors ensure uniform frequency response for low distortion. The player is also MQA-compatible. If you're a TIDAL subscriber, you can enjoy your music through this innovative high-resolution format.

The player has a traditional 3.5mm stereo headphone minijack and a 4.4mm balanced output jack. With compatible headphones, this balanced output gives you superior stereo imaging, with fully discrete right and left channels.

Exquisite sound. Use it with Focal Elegia's and just get lost in the music. Easy to operate and load music onto as well. Doesn't have streaming capabilities, but can be used as DAC/amp and stream via smartphone or tablet. Very happy with product and support from Crutchfield.

Pros: Sound, battery life, ease of use.

Cons: No direct streaming

Great DAP when used to its full potential

Marco from Washington, DC on 9/7/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

I wanted a self-contained DAP that had expandable memory, didn't rely on Wi-Fi in order to function, and had a balanced output to which I could connect my balanced headphones. The Sony NW-ZX300 really fit the bill. It's a great little portable device that has excellent sound quality and a long-lasting battery. When I bought it, I already owned a pair of Sony's MDR-1000x wireless headphones that I felt weren't being used to their highest potential. Using the player's LDAC codec with my wireless hadphones was a revelation -- punchy and detailed and sooo much better than AAC or aptX. Of course, the MDR-1000x's can't match the fidelity of a high-quality wired headphone, but using the player's LDAC codec gets you a lot closer to it. Speaking of wired headphones, once I got a headphone cable for my Hifiman Edition X v2 terminated in a 4.4 mm balanced plug, listening via the balanced output (with high gain) sounded even better. The Sony's equalizer and DSEE HX function are great to have, but I think the Sony sounds best with music as-is (via the Direct Source option). This DAP started me buying CDs again, in addition to buying downloaded Hi-Res music. I bought a lot of music I liked (from Tidal) so I could listen to it on the Sony DAP. If you don't already have a great FLAC and HiRes music collection, you should invest in them to get the most out of this player. If your music collection consists of MP3 or AAC, I think the Sony NW-ZX300 is an expensive option not worth getting.

Pros: Excellent sound (w/FLAC & Hi-Res music) Balanced output option Can be used as an USB DAC Long-lasting battery Expandable memory

Cons: Takes a while to charge fully Sony software for the player is pokey Screen smaller than it should be (newer Sony DAP uses all space) Proprietary cable Amp not powerful enough to fully drive higher-impedance headphones

Great sounds

Music sounds great thru this device. It's a nice portable music player for those on the go, that want to hear music at its finest. On the bad side, it takes some research to figure out more than just playing some songs. The blu tooth sync is forgetful in my vehicle too.

Pros: Sound clarity.

Cons: Blu tooth vehicle snyc.

Exceptional sound reproduction with balanced tones!

Must properly break in! I was hesitant to purchase this for as many negative reviews I'd seen over its lack of "punch", bass, dynamic sound, and more. Upon using it the first time my impressions were the same. I was prepared to return it. However, there is a "Guide to High Quality Sound" in the device settings which clearly detail the requirement for proper break-in. The tutorial explains that this device uses new, proprietary polymer capacitors, which must be broken in. It says, "The electrical characteristics of these capacitors become stable after about 200 hours of use, reaching the point where they produce the highest quality sound." Furthermore, this a requirement is for each headphone port in that there are different capacitors for both. For the capacitors to break in, headphones must be plugged in and powered at normal volume for the process to be achieved. I took the bait... I purposed to not make any decisions to return until the chronometer on my Walkman achieved 200 hours of playback time. Knowing I had a return window to work within, I simply plugged in headphones each night, and set the Walkman to "Play" overnight until after a few weeks I'd achieved the coveted 200 hour mark. The difference was night and day! I'm willing to bet most early reviewers did not allow for proper break-in and made rash judgments based on non-optimal functioning of the non-broken-in capacitors. I'm thoroughly enjoying it in the car, for air t

Pros: - warm, dynamic tones - plays virtually every known digital format - great battery life - comprehensive user and listening features - broad range for usage

Cons: - break-in period required, and is an absolute must in order to experience full potential - User interface is a bit antiquated (think decade-old iPod UI) - touchscreen not opertional for powering on/off the device, nor waking screen fro sleep during usage. In order to toggle the screen on and off you must depress the Power button on the side of the device. Not a major problem - merely an inconvenience and not consistent with other modern smart devices.

Very good DAP

Graeme from Las Vegas, NV on 3/25/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Solid product. Nicely designed. I wanted something that would be comfortable in my gym shorts and this fits the bill with nicely rounded corners and not too heavy. File transfer is very straightforward (drag and drop). Sound is clean and accurate on my 16 bit files transferred from CD's however I was hoping for more separation. But amazing sound from purchased 24 bit files. No discernible hiss. Will definitely benefit from being paired with the correct IEM's.

Pros: 24 bit files sound amazing

Cons: Re-building a music library with HD files can get expensive!

Does this player have the ability to store and play Tidal albums in offline mode in the same way that Apple and Android devices do?
[ Vlad  Jul 25, 2018 ]
4 answers
No. This player does not have any Wi-Fi capabilities. You are limited to playing music stored on the player.
[ Marc  Jul 26, 2018 ]
No, the Sony NW-ZX300 isn't able to connect to the internet. You can however use this as a DAC on your computer while streaming MQS from Tidal. Also as far as I can tell you can't use it as a DAC with an iPhone.
[ JELANI  Jul 26, 2018 ]
There is no network connectivity - no app-based streaming, etc. It is more like a classic iPod. Files must be manually managed, transferring from a PC or Mac using either the free Sony software or by simply dropping and dragging files to the player while connected via the included USB cable. I don't know enough about Tidal to answer your question directly. If Tidal allows you to download files and transfer them to an external device then I don't see why it wouldn't work. But, is they are copyright protected and prevent from downloading to a PC or Mac I'm not sure it would work. What works well is adding files from CDs (ripping to FLAC or ALAC using the software of your choosing - i.e. iTunes), adding files from Hi-Res audio purchase sites like Hdtracks, Qobuz, 7digital, etc., or adding DSD files either purchased or ripped from Super Audio CDs (SACDs).
[ Josh  Jul 25, 2018 ]
Not that I'm aware of.
