Sony Walkman NW-A306 In-Depth Review – Hi-Res Audio for the Budget Audiophile

The Sony Walkman brand started in 1979 with personal battery powered cassette players. That was genesis for the portable audio industry, one of the first personal audio player small enough to fit in your pockets. The boom in the stereoscopic headphone industry can also be attributed to that.

In 2001, Apple brought their famous iPod to market. When that launched, the iPod became the household name for portable audio. All the other brands, including Sony’s Walkman, had to take a backseat.

Today, something like an iPod is ‘old-fashioned’. You can store lossless audio files and even play them on a modern smartphone. There are many streaming platforms today as well offering you music and even podcasts at the same time.

For all of these, you trade audio quality for convenience. Proper audio processors will make your smartphones bigger. Your streaming platforms use highly compressed audio for better economy, latency, and efficient storage.

For audiophiles and purists though, convenience is a hindrance to purity and greatness. A dedicated media player is always the way to go. Sony’s Walkman is still one of the biggest brands in this space. In the Walkman stables, there are also options to fit different budgets.

One of their latest additions to the Walkman family is the NW-A306, a mid-range media player for enthusiasts. It packs Android 12, like a smartphone. It is an extra device in your gear bag that will set you back MYR 1,599. In that case, is this relevant? Is it even worth the asking price?

It looks like a rather compact and thick smartphone. Thanks to Android 12, it feels like an actual smartphone. Unlike a smartphone though, this has more buttons than the usual on/off an volume rocker buttons.

The front of the device is a glass plane protecting a 3.6-inch LCD panel and Sony branding at the bottom. The camera-less ridged back plate with a Walkman badge carved into it is aluminium. The ridge is meant to improve grip, we think. We reckon that a cheap silicon case would do a better job.

The sides are also aluminium like the back plate. On the right side of the device is where all your media and volume control buttons are. There is also a ‘hold’ toggle to prevent accidental presses. The entire device speaks quality and feels rigid, durable.

You can only get the NW-A306 in boring ol’ black. It is not meant to attract attention though. We would go so far to say that the Sony NW-A306 is meant to be subtle and stealthy.

Hardware

Sony does not mention the sort of processor inside the device. It is made with audio in mind though. For that, Sony has several effects processors inside for better audio reproduction and immersive effects.

Features

You can upload MP3 files in the thousands, which would be a waste. You want FLAC or WAV format in the NW-A306 to get the best out of it. If you can, you want DSD format audio for it.

Android 12 Interface

Sony NW A306 11

Android is a familiar interface. Everything is intuitive and where you expect to find them. Even if it is not the most updated Android 13, it is familiar and simple to work with.

You still get Bluetooth and WiFi, but that is about it for connectivity. You will not be able to customize too much in terms of your back, recent apps, and home button too. But they are there, like a regular Android.

You can access Google Play Store. You can install Netflix and Prime Video, but you watch movies at HD resolution and on a miniscule screen, we do not recommend it. You can install other media players for it if you want alongside Spotify and Tidal.

DSD Audio Playback

All the NW-A306’s hardware goes into supporting one of the best lossless audio formats you can get. While technically you do not lose too much audio artifact through 32-bit FLAC and WAV formats, you still lose some artifact thanks to limited sampling rate at up to 384 KHz. That is not the case for DSD format.

The specific DSD format the NW-A306 plays is up to DSD 256, or DSD 11.2 Mhz. Whichever way you look at it, 11,289,600 Hz is plenty more than 384,000 Hz, meaning you get a lot more detail in your audio. FLAC and WAV formats offer better depth though. At up to 32-bit, you technically have much higher volume floors offering more powerful and full low-end sounds. Even then, 1-bit DSD 256 format audio contains somewhat more detail and with the right headphones, you might prefer it.

The difference is marginal and might not sound too different over untrained ears. You also need quality headphones with neutral and balanced drivers to tell the difference. Sony does not include any earphones with the NW-A306.

Direct, or Processed

Sony NW A306 03

The amount of customization and upscaling you can get from Sony’s media player is nothing short of astonishing. If you thought that Sony’s wireless headphones do well in upscaling audio, you might want to try one of these with a decent pair of headphones.

You get DSEE Ultimate, DC Phase Linearizer, Dynamic Normaliser, Vinyl Processor, and if you are too lazy to find out what you like; you get ClearAudio+ to cleverly transform your music listening experience via a single toggle. If you do not like any of those upscaling artifacts, you can even get to bypass all of Sony’s filters and effects via Direct Source mode or tune it to your personal preference with a 10-band equalizer.

We are not going to go into the technical bits of each effect that Sony offers. All you need to know is that each effect offers a different enhancement to your audio and some of them are pretty self-explanatory. Vinyl processor for example, offers a vinyl like listening experience which adds some warmth and reverb into your audio. We simply turned on ClearAudio+, which will turn off access to every other individual effect.

ClearAudio+ offers Sony’s DSEE Extreme, and other clever AI based effects to enhance your audio from a single toggle. You get more details in your music and the algorithm boosts your volumes a little too. Without ClearAudio+, we set the media player at more than 80% volume. With ClearAudio+, we only need to turn it up to 75% at the maximum.

Sony’s clever DSEE and ClearAudio+ does not just work for the regular DSD or FLAC audio you put into your media player. It also works for the music streaming apps like Spotify and Tidal. You can turn on Hi-Res streaming and the NW-A306 will cleverly upscale your output to 192kHz/32-bit quality.

Your Portable DAC

If you plug it into your PC via a USB cable, you might see a DAC mode on offer. It is not the straightforward plug-and-play solution we expected though. You want to have Sony’s Music Center app for your PC, or Hi-Res Audio Player for Mac. On PC, you are limited to 32-bit 48kHz input/output, which is not quite Hi-Res. Once you have your app installed, and you plug in your device to the PC or Mac via USB, and then select USB DAC mode, you must go into the Walkman app and find “USB DAC” button on the main library screen. Only once you activate DAC mode from there then only you can start enjoying it as your DAC.

With the NW-A306 as your DAC your music listening experience is transformed and you really feel like you are listening to a completely different device even with Tidal and Spotify. You get a much wider sound stage and improved dynamics. Your highs and lows are more distinct and plenty more detailed. You even get deeper lows and better volumes out of your PC.

There is a small matter of delay though. Pressing play on your Tidal or Spotify player takes about a second for the action to turn into audio. It is negligible for music, but it may not be ideal for Gaming or Movies.

Bluetooth Audio + LDAC + Qualcomm aptX HD

Sony NW A306 04

Unlike plenty of traditional media players, the Walkman can be used with Bluetooth enabled headphones. It is not just Sony’s headphones though. You can use it with any Bluetooth headphones. We tested it with the Sony WH-1000XM4.

The WH-1000XM4 is not a Qualcomm device with aptX HD chip. Instead, it works with Sony’s proprietary LDAC for the best possible Bluetooth audio experience. If you do have any other headphones that supports aptX HD though, you can work with the media player.

While it is Bluetooth enabled, the sound quality is only as good as Bluetooth 5.0 allows it to be. It also highly depends on the version and calibration of the Bluetooth gear. We think that using a wireless set-up with the NW-A306 is not the best. It is convenient though.

360 Reality Audio

The NW-A306 is marketed to be capable of 360 Reality Audio. The effects of the surround sound are highly dependent on your listening gear too. You want to have a compatible set-up for this. The WH-1000XM4, for example, is sufficiently capable.

We can also only get 360 Reality Audio music and audio from Tidal at this time. That also means that you have to rely on using Tidal to take advantage of 360 Reality Audio. The Walkman app refuses to play 5-channel FLAC and DSD audio files.

We spoke about 360-Reality Audio at length when we reviewed the WH-1000XM4. In that case, we are not going to elaborate on the 360 Reality Audio experience here. In short, we like it.

Performance – There is a Difference

Sony NW A306 17

The NW-A306 is not a gimmick. Even at this price range, there is an actual difference between listening to audio with this media player over your modern smartphones. That does not only come from us.

We pitted the NW-A306 against a modern smartphone, the Samsung Galaxy S21 Ultra, and used Tidal as the benchmark. We used a Shure SE535 in-ear monitor earphones on both devices with custom cable from KZ. For the Samsung Galaxy S21 Ultra, we used a USB Type-C to 3.5mm DAC adapter from UGreen.

Smartphone Versus NW-A306

Even with Tidal, there are differences. You get slightly more dynamic range from the NW-A306 than you get on the smartphone. Volumes do not necessarily differ all that much between the two devices, but you get more granular control over volume with the media player. There are also slightly more details in the music on the NW-A306.

Just so that we eliminate any fanboy bias, we let others test the NW-A306 against the smartphone. Most are not able to define the difference, but they preferred the listening experience from the Sony media player. While there are differences, they are so marginal that most might consider it negligible.

Going Hi-Res

Sony NW A306 08

Once we get to FLAC and DSD files though, the media player makes more sense. Those who have tested the media player with FLAC and DSD audio reports that you get a significant boost in sound quality. Most of them also prefers DSD audio formats than FLAC. To be fair, we could only get our hands on 24-bit/192kHz FLAC files at the maximum while the DSD files go up to 11.2MHz at 1-bit.

With FLAC, WAV, and DSD format audio, you are getting a tremendous amount of detail pumped into your ears. You get a full sense of width and depth of the dynamic range with these files. You are technically getting CD quality sounds and better. Audio is not just accurate; it also sounds great and clean.

Some Electronic Interference

It is not perfect though. There is still some electronic hiss that goes through to the headphones. You are likely going to put your audio levels at about 70 – 75% volume and the hiss is noticeable at those volume ranges. Once you start playing your music though, the hiss disappears behind the music.

Only 10-Band?

You can switch off ClearAudio+ to select the effects you want and tune your audio via the 10-band equalizer. We think that Sony could give us more than 10-band in their equalizer option for even more control. This is still better than what you get with your Sony Music app on your smartphone though.

Battery Life

Sony says you can get 36 hours of non-stop music playing time with MP3 music. If you play DSD 11.2MHz files exclusively, you only get 14 hours of playback time. This is also considering that you are using a wired 3.5mm jack headphone. That easily covers an entire flight from Kuala Lumpur to London for example.

In our tests, we have not been able to extend the battery life to 14 hours while playing FLAC and DSD files. We estimated that the battery can last up to 10-12 hours in a single full charge at least in our test with music played through the Walkman app. We do recon that you can get about 14 hours of playback time out of it though if you keep your screen turned off while playing music.

The Sony NW-A306 – You Do Not Need it, But You Kind of Want It

Sony NW A306 02

At MYR 1,599, it is not what we will call a budget or even sensible buy. While it does sound better than the regular ol’ smartphone, it is marginal if you are only relying on music streaming platforms like Spotify and Tidal. To most, the difference is not enough to justify spending MYR 1,599 for an extra piece of kit to carry. The tiny HD resolution display is not exactly the best to enjoy Netflix and Video Prime on. To source for FLAC or DSD files is an effort too.

When you make the extra effort though, the NW-A306 makes sense. You get an elevated music experience over smartphones. It is no larger than a modern smartphone, making it rather portable. You have the convenience of wireless headphones but spending extra money on a great pair of wired headphones gets you an uncompromised listening experience. You can even use it as a DAC for your PC. If you can appreciate all of that, MYR 1,599 now seems more reasonable.

Is it relevant? We think it is. It is made for those who do not want to compromise too much on sound quality – audiophiles. It is for those who want to keep their devices separate from each other by function. It is for those who want no distraction from their music, a sort of separation between work and enjoyment.

At MYR 1,599, this NW-A306 is reasonably accessible. There are going to be other costs that is attached to buying this music player. You are going to have to spend more on a decent pair of wired headphones. You are also going to be spending a little bit of money on your music collection. Thing is, if audio quality is everything to you, it is worth it.
