Sony WF-1000XM4 evaluation: What goes within the ear, stays within the head

Sony fees a whopping $279 for its new WF-1000XM4 wi-fi earbuds! The vastly convoluted mannequin identify that makes it tough to reference in on a regular basis dialog is nonetheless probably the most extremely rated wi-fi earbuds round. As as to whether I can sing equally constructive tunes about it after per week of day by day use, why not discover out in my evaluation?


  • Excessive-quality sound
  • Nice ANC efficiency
  • Has LDAC and DSEE Excessive features
  • Very straightforward and handy to make use of
  • As much as 12-hour battery life


  • Slot in ear takes just a little getting used to
  • No AptX (HD) help
  • Sony must revamp their app
  • 360 Actuality Audio is cool to have however impractical

Conclusion: The very best could also be costly

The Sony WF-1000XM4 is without doubt one of the most anticipated in-ear Bluetooth earbuds with ANC that you may decide up in June 2021, or if I dare enterprise, for the entire 12 months! That is how I might sum up the conclusion in a single sentence. You could be stunned at how a lot I gush in regards to the quite a few positives that these Bluetooth earbuds provide, in addition to Sony’s consideration to element.

Make no mistake about it: Sony’s new top-of-the-line wi-fi earbuds sound good, they ship ANC on par with the over-ear different WH-1000XM4 and carry all the premium options that one would count on from a high-end audio machine in 2021. As well as, the battery life is superb whereas it has additionally made progress by way of design with a extra compact charging case.

Nonetheless, I do really feel that the WF-1000XM4 didn’t all the time match properly in my ears. I additionally really feel that Sony’s app appears quite dated and wishes a refresh, in any other case, it could tarnish the premium really feel just a little bit. Nonetheless, I might strongly suggest you decide up the WF-1000XM4 when you’ve got $280 to spare for wi-fi earbuds which are as small as a glove of garlic, which additionally will increase the chance of them getting misplaced when you’re not cautious. 

Design & sporting consolation: Match not all the time optimum

The Sony WF-1000XM4 will be thought-about because the wi-fi model of its basic in-ear headphones.
This implies the earbuds are held in your ears through earplugs with out a retaining clip of any kind. A single earbud ideas the scales at barely lower than 7 grams, whereas the included charging case weighs 41 grams. The case has shrunk in measurement in comparison with its predecessor.

What I preferred:

  • Trendy design
  • Smaller charging case
  • Excessive-quality workmanship
  • IPX4 certification

What I disliked:

  • Match isn’t all the time optimum (extra on this under)
  • Ear ideas protrude far into the ear

Visually talking, you may discover a distinction between the WF-1000XM3 and the WF-1000XM4. Sony has managed to forge a brand new path for itself by making the spherical and round design an iconic and immediately recognizable one. Herein lies the issue: there is not a lot wiggle room in the case of making it stand out from the remainder of the group. Whether or not you just like the design or not, is in fact, a matter of style.

What can’t be denied, nevertheless, is that Sony has shrunk the charging case. Though the person earbuds are quite massive in measurement, the case measures simply 6.5 x 3 x 3.5 centimeters (W x D x H). With a weight of 41 grams, it’s hardly noticeable in my pockets or my hipster chest bag. Its bulkier predecessor truly made you conscious of its presence everytime you carried it round, which could be a superb factor when you’re much less cautious together with your belongings. 

If it begins to rain whereas sporting them, you too can go away the WF-1000XM4 in your ear with none worries. They’re protected towards water splashes primarily based on the IPX4 normal, and thus, making them appropriate as sports activities headphones. Sporting it on my jogging route after three laps, the in-ear Bluetooth earbuds proved immaculate in delivering music and podcasts whereas I pounded the pavement.

Sporting consolation

And that brings us to the matter of sporting consolation, which did not fairly fulfill me at first. By default, Sony inserted the medium-sized earbud ideas which had been most likely too massive for my ear canals. It may be the explanation as to why they saved falling out, to not point out I additionally struggled with ear ache.

Since I could not obtain a safe match, I stuffed the earbuds additional into my ears the place they will need to have ended up too deep within the course of. What is bound to amuse the youthful era is the truth that I made a decision to downgrade the information by one measurement. Do take be aware that Sony’s app additionally gives a operate to find out the optimum earbud tip measurement. 

Regardless of counting on the app’s suggestion, I nonetheless do not feel one hundred pc assured strolling round with the WF-1000XM4 in my ears. It could be a matter of desire, however the stem design full with silicone ideas of the Oppo Enco X makes me really feel safer when I’m biking and operating. Maybe the concern of shedding them stems largely from the excessive worth of the WF-1000XM4. 

TL;DR: Sony produced a wonderful piece of eye sweet with the WF-1000XM4. For those who do not just like the design, you possibly can a minimum of be completely happy a few smaller charging case. Sporting consolation could possibly be higher for my ears, however that is a matter of style. Kudos for Sony’s environmentally pleasant packaging. Arigato gozaimasu, Sony-San!

Sound: I’m now spoiled

Throughout the Sony WF-1000XM4 lie 6-millimeter drivers accompanied by high-performance neodymium magnets.
They cowl a frequency vary of 20 to 40,000 Hertz when you make use of the high-quality LDAC audio codec. As well as, the earbuds help the DSEE Excessive normal with a 96-kHz sampling charge at 990 kilobits per second.

What I preferred:

  • Highly effective and customizable sound
  • Excessive-quality audio codecs (LDAC & AAC)
  • 360-degree sound put a giant smile on my face

What I disliked:

  • No AptX (HD)
  • 360-degree sound characteristic will not be used typically
  • 5-band equalizer solely and bass optimization

With high-quality drivers and the appropriate Bluetooth codecs, Sony has created the perfect circumstances for high-quality sound on paper. Whereas Apple equips its personal music streaming service with a lossless characteristic and its personal AirPods don’t essentially characteristic the mandatory technical necessities for this, the WF-1000XM4 are technically outfitted for Tidal, Amazon Music HD, and different comparable providers. That is attributed to LDAC and occurs to be Sony’s very personal Bluetooth codec. Assist for AptX, nevertheless, has been dropped this time round, because it was final provided by Sony with the WH-1000XM3. Apple followers, nevertheless, could have a smile on their faces with the AAC codec.

In my evaluation, I subscribed to the premium music streaming service Tidal, which streams in MQA format at as much as 4,608 kilobits per second at 96 kHz and in 24 bits. On Android 11, you possibly can ship the excessive streaming high quality to the earbuds because of LDAC earlier than optimizing the sound additional with Sony’s DSEE Excessive. Whereas LDAC ensures notably “dense” knowledge when listening to music, DSEE Excessive optimizes the replica of the frequency responses which are misplaced when compressing the unique sound supply.

The outcome? Spectacular sound high quality, which can also be aligned to Spotify Premium and with out LDAC. The WF-1000XM4’s drivers ship loads of energy throughout all conditions, and with just a few tweaks to the equalizers in Sony’s app, you’ll adapt the earbuds properly to your listening habits.

On Spotify, you will discover my evaluation playlist for headphones and earbuds, the place I break it down additional into a number of genres. Regardless of the sound high quality being constant throughout genres, I nonetheless discovered myself gravitating in direction of jazz with Chick Corea entertaining me more often than not throughout the complete week. If I had been to take pleasure in metallic à la Gojira or Tyler, the Creator’s juicy hip-hop beats additionally sounded stylish. By the way in which, he launched a brand new album on the day this evaluation was revealed, so this is a listening tip when you’re into metallic! 👌

360 Actuality Audio is spectacular, however hardly ever used

One characteristic that I do not wish to go away unmentioned is Sony’s 360 Actuality Audio. This characteristic is greatest in comparison with Apple’s 3D sound or in fact, Dolby Atmos. The purpose is to ship a sensible encompass sound expertise to a pair of snoozy stereo earbuds. As a way to activate the characteristic, you may have to take a photograph of your ears together with your smartphone.

Sony will then analyze your ear construction and calculate how spatial sound would enter your ears. The truth that practical encompass sound can also be doable with stereo headphones has been recognized a minimum of because the digital haircut primarily based on binaural sound recordings, which will be heard on YouTube.

Sony additionally simulates encompass sound primarily based in your ear form, and once more, it wants the suitable audio supply to realize optimum outcomes. Amongst different issues, Tidal helps 360-degree audio recordings. Once you unbox the earbuds, you possibly can activate a free trial on Tidal, Deezer, or nugs.internet through a coupon, albeit with solely 20 tunes obtainable within the Tidal catalogue. Sadly, that is not sufficient for Sony’s expertise to make the leap from tech demo to on a regular basis use.

Deezer’s devoted 360 app presents a complete lot extra, however the streaming service additionally prices $14.99 for the HiFi model. So after the three months of the free trial through Sony’s coupon, it finally ends up as costly enjoyable.

That is to not say Sony’s tech demo is not enjoyable and entertaining although. I discovered myself grinning in my condominium whereas listening to Foo Fighters’ Everlong (on Tidal). That is one thing about this expertise that triggered one thing in me that I’ve by no means felt in a really very long time. For those who had been to shut your eyes whereas listening to it, you’d actually sink into the music because it occurs round you. That is particularly apparent after months of lockdown with out reside music, and that is in some way very cool.

Sound is adjustable because of a 5-band equalizer

I additionally must level out the positives of Sony’s sound optimization through its equalizer. Though you solely have a 5-band equalizer at your disposal, this can be very potent. As well as, there’s additionally bass optimization and 10 presets to select from along with two customized settings.

Primarily based on an evaluation of your listening to, corresponding to utilizing the superb Soundcore app, is one thing that Sony misses out on. Essentially talking, nevertheless, I want to criticize the Sony app right here. As an app companion for such an costly audio product, I discover Sony’s app to be just too old style and cumbersome to make use of.

Sure, the app shines with a variety of features and with a little bit of familiarization, you will discover your method round. However the app is just too old style in its interface and would not provide a very good consumer expertise for my part. Perhaps you are not too bothered by this, however after reviewing the Soundcore Life Q35, Sony’s app stands out negatively compared.

TL;DR: The Sony WF-1000XM4 is technically and acoustically sound. In on a regular basis use, fashionable requirements corresponding to DSEE Excessive and LDAC are notably spectacular, offering the high-quality drivers with the mandatory materials to point out off its functionality. All in all, they’re as near Hello-Fi headphones so far as wi-fi Bluetooth earbuds are involved.

Noise cancellation: On par with Sony’s over-ear fashions

In fact, Sony additionally outfitted its WF-1000XM4 with lively noise cancellation.
Along with the passive attenuation because of its foam earplugs, Sony additionally depends on its new V1 processor to ship out much more exact and latency-free anti-noise. There is a transparency mode too, which will be enabled routinely when you so need.

What I preferred:

  • ANC could be very efficient total
  • Ambient Sound Management works properly

What I disliked:

  • No adjustable ANC ranges and works solely together with ambient sound
  • Transparency mode could be very inclined to wind
  • Ambient Sound Management has annoying notifications by default

Sony is already skilled in the case of ANC (Lively Noise Cancellation), persistently making it to the highest of greatest ANC lists, particularly in its over-ear headphones. What the Sony WH-1000XM4 does, additionally, you will get hold of in an identical type with the in-ear fashions. For my part, the earbuds do not actually have to cover behind the over-ears in the case of ANC anymore.

For instance, in the case of noise, visitors sound is nearly fully filtered out. For those who had been to modify backwards and forwards between the transparency mode (Ambient Noise Management) and ANC, you’ll obtain an impression as when you had been dipping your head underwater. That is just about typical for all ANC headphones and earbuds, nevertheless, sudden noises are additionally suppressed in a much less efficient method.

Strictly talking, Sony would not provide a gradual regulation of ANC. As an alternative, you possibly can regulate the effectivity of the noise cancellation by enabling transparency mode. Sony has dubbed it as “Ambient Sound Management” and it presents one other actually cool consolation characteristic right here.

Earlier than I let you know in regards to the wonders of Adaptive Sound Management, right here is another factor that I disliked about it. Though Sony presents a mode to cut back wind noise, it comes via very strongly in transparency mode. When driving my bike, I needed to flip off Ambient Sound as a result of the wind noise was too loud.

Adaptive Sound Management

However now for the cool characteristic, as with “Ambient Sound Management”, the Sony app acknowledges the actions of your smartphone. In doing so, the app will routinely change between just a few modes. For instance, when you’re sitting at your desk within the workplace, the ANC will fully block out the noise from annoying colleagues.

For those who had been to stand up and do not wish to miss any flirting alternatives in your technique to the bathroom, the earbuds will routinely change to “strolling” mode and activate transparency mode with an non-compulsory concentrate on voices. The complete mechanism aggravated the heck out of me at first, as there was all the time a notification delivered to my smartphone and my music would go quiet briefly. You may flip the sound notification off although, and you too can configure areas with fastened settings when you do not want ANC corresponding to if you find yourself at residence.

TL;DR: Sony’s in-ear Bluetooth earbuds not solely does ANC very properly, however additionally they added intelligent options alongside the way in which. The Adaptive Sound Management isn’t the world’s first, nevertheless it nonetheless is aware of the right way to ship. The one factor I want to see is healthier regulation of the ANC with out transparency mode, as that is fairly inclined to wind noise.

Battery life: As much as 12 hours – or a full Rush music

You may hearken to music with the WF-1000XM4 for 12 hours at a stretch, so long as you deactivate ANC.
With noise cancellation enabled, the runtime drops to roughly eight hours. The charging case which additionally helps wi-fi charging incorporates sufficient energy to ship one other 16 hours with ANC and one other 24 hours with out. Sony has additionally conveniently considered together with a quick-charging characteristic besides.

What I preferred:

  • Superb battery life total
  • Fast-charging and wi-fi charging supported
  • Discreet “battery low” announcement

What I disliked:

  • Earbuds run out of juice at completely different occasions as a result of their particular person fees

For those who’ve learn my quick introduction above in regards to the record of professionals and cons, you’d already know every little thing in regards to the Sony WF-1000XM4’s battery life. Having a battery lifetime of as much as 12 hours is excellent within the in-ear Bluetooth earbuds market, and even with ANC enabled, you’ll make it via a full workday.

Do you wish to go for a fast jog and see that the headphones are operating on empty? You may add an hour of music enjoyment in a matter of simply 5 minutes because of Quick-Charging. This spectacular characteristic is rounded off by the inclusion of handy wi-fi charging. When it comes to battery life, the one adverse factor that I might have observed is the person earbuds generally have completely different battery ranges. In on a regular basis use, nevertheless, this isn’t an issue.

TL;DR: Runtime of as much as 12 hours is certainly a powerful level! The truth that Sony additionally considered handy options corresponding to fast charging and wi-fi charging rounds off the entire thing. Kudos!
