Sony WF-1000XM4 Evaluate: Merely Elegant

Sony’s newest flagship wi-fi earbuds are right here and the WF-1000XM4 arrive with excessive hopes of being one of the best you should purchase, taking up Apple, Bose and lots extra. 

In addition to a brand new, extra compact design, the XM4 have a ton of recent good options together with Ambient Sound Management and Communicate-to-Chat. 

Design & Construct 

10% smaller earbuds 
40% smaller case 
IP4X water resistance 

In case you are accustomed to Sony’s earlier earbuds, you’ll discover that the XM4 introduce an overhauled design. Gone is the elongated oval form of the WF-1000XM3, changed with a round bud with a bump on the aspect the place the ear tip protrudes. 

I’ve examined the black color however you’ll be able to select silver for those who like, with each sporting a gold trim. Importantly, they’re 10% smaller than the earlier gen and weigh 7.3g every.  

I favor the brand new form – which is designed to suit the ear cavity – however there are smaller/lighter earbuds on the market, so anybody with small ears may discover them to be slightly cumbersome. You get three sizes of suggestions within the field, and they’re a reminiscence foam sort materials to attain a snug and air-tight match. 

I discovered the buds to sit down in my ears fairly properly and though I’ve considerably unusually small ear canals, the smallest measurement of tip was enough. The XM4 by no means fell out, even when chasing my canine across the backyard, which stunned me. 

Once you intentionally take away the buds, sensors will guarantee the music is robotically paused after which resumed if you put them again in. 

On the surface of the buds are touch-sensitive buttons that work rather well and though it’s not a better score, the IPX4 water resistance needs to be sufficient for most individuals, that means they will deal with splashes and sweat. 

Just like the buds, the case has been shrunk, though much more at 40% smaller. It’s an excellent little case with an LED on the entrance, USB-C on the again and wi-fi charging. I discovered getting the buds out and in easy.  

Lastly, it’s good to see eco-friendly packaging right here of which 99% is created from recycled and sustainable supplies. There’s no plastic in sight. 

Sound High quality 

6mm drivers 
LDAC with Hello-Res Audio Wi-fi 
DSEE Excessive 

Sony has confirmed that measurement isn’t the whole lot by sticking with 6mm drivers when you may get earbuds with drivers twice the dimensions, and even larger. Nevertheless, it truly is what you do with it that counts right here because the WF-1000XM4 sound nothing in need of breathtaking. 

The agency says they “reproduce a dynamic sound regardless of their small measurement, and the excessive compliance diaphragm reproduces a wealthy bass vary.” and I’m in no place to argue contemplating how good they sound. 

Hidden beneath the stealthy shell is a number of tech to make this occur together with Sony’s Built-in Processor V1 which, partly, reduces distortion. The XM4 assist the LDAC codec which might switch thrice extra information than standard Bluetooth and permits Hello-Res Audio Wi-fi. You’ll need to connect with a tool that additionally helps LDAC, thoughts, though that is not too troublesome because it’s obtainable on telephones working Android 8.zero or later. For iPhone customers, the XM4 helps AAC.

DSEE Excessive (Digital Sound Enhancement Engine) expertise means the earbuds can upscale compressed audio in real-time. 

I examined the XM4 earbuds with a variety of gadgets and audio sources and so they merely sound wonderful no matter you resolve to hit play on. The audio high quality is wealthy, crystal clear and balanced. 

Moreover, they assist 360 Actuality Audio which is Sony’s spatial audio expertise for a encompass sound expertise. Simply word that you just’ll want to make use of a streaming service that helps it like Deezer or Tidal with the proper subscription plan. 

The app can assist you discover the suitable ear-tip measurement by testing the match and there’s an EQ if you wish to customise the sound. 

Noise Cancelling & Good Options 

Ambient Sound Management 
Customisations galore 

Sound high quality is one factor, however many individuals will probably be shopping for the XM4 for the lively noise cancelling (ANC) and different good options. And let me inform you, Sony has not held again right here. 

As we’ve turn into accustomed to with Sony headphones, the noise-cancelling expertise is insanely good and arguably one of the best you may get. The one wi-fi earbuds that I’ve examined that come shut are the Bose QC Earbuds. 

Nevertheless, the WF-1000XM4 include so many additional good options that they actually stand out from the gang. 

After all, you get issues like an ambient mode to listen to your environment with an adjustable degree (20 ranges to select from, no much less) and wind discount on the principle mode, however there’s a lot extra right here with the identical options of the over-ear WH-1000XM4 packed into earbuds. 

The principle function is known as Ambient Sound Management and might robotically regulate the profile relying on the place you’re or what you’re doing. For instance, ambient sound will probably be engaged if you begin strolling and noise cancelling if you keep nonetheless – these are outlined as actions with working and transport having presets. 

Sony has additionally enabled particular areas to be registered akin to your workplace, a café you frequent or the gymnasium. Within the Headphone Join app, you’ll be able to register locations from discovered areas or simply set your individual through a map. And like a number of issues within the app, for those who don’t like both actions or areas may be switched off and you’ll customise nearly the whole lot with fine-tuning for those who like. 

It nearly goes with out saying that the headphones assist digital assistants – Alexa and Google – however there are nonetheless extra good options to speak about, with discuss being an apt phrase.  

Communicate-to-Chat does what it says on the tin, so the earbuds can detect if you’re talking with a purpose to each pause your music and change to ambient mode if it’s not already on. Speaking to somebody I do know, I’d somewhat take no less than one bud out, however I can think about them being helpful for conditions like ordering a espresso earlier than getting a prepare when your arms are full and it’s troublesome to take away an earbud. 

Battery Life & Charging

One space that hasn’t had an improve in comparison with the final mannequin is battery life with Sony touting a complete determine of 24 hours – that is eight from the buds after which an extra 16 from the charging case. 

Whereas there are earbuds that may go longer, these figures are nonetheless very respectable and, maybe crucially, are higher than Apple and Bose rivals. And people numbers are with ANC on so with it of the XM4 can final a formidable 36 hours. 

In my testing, the battery life held up very properly typically getting round one hour per 10% of juice even with ANC on – albeit sitting in my pretty quiet workplace. 

As talked about earlier the case now has Qi wi-fi charging making it simpler to high them up. Quick charging means you may get an hour of playback from a brief five-minute cost. 


As you may anticipate, Sony’s flagship earbuds include a flagship worth. At £250/US$280, they’re dearer than their predecessors however match rivals just like the Bose QC Earbuds and AirPods Professional. 

They’re obtainable direct from Sony or a variety of shops within the UK together with Amazon, Currys PC World, Argos and John Lewis. 

Within the US, you should purchase them from Amazon, BestBuy and Newegg.

You’ve obtained to have the money to splash, however for those who do you then actually can’t get higher than the Sony WF-1000XM4 for wi-fi earbuds. Though I can perceive the argument of AirPods Professional for iPhone customers. 

Nonetheless, the XM4 are price contemplating it doesn’t matter what cellphone OS you’re loyal to. The brand new design is extra compact and lighter and that’s actually simply the tip of the iceberg. 

On high of top-notch sound high quality and noise cancelling as commonplace, the XM4 are packed to the rafters with further tech and good options. Ambient Sound Management can robotically change between completely different modes as you progress or arrive at a selected location.
