Sony’s flagship earbuds are its best yet, boasting a new design, a more natural sound and beefed-up ANC. While the tips and fit could be improved, they’re the buds to which most rivals currently aspire.

The Galaxy Buds 4 Pro are the best wireless earbuds that Samsung has made yet. They sound detailed and clear, with an admirable feature set and a comfortable, appealing build.

Samsung is up for the challenge. The Korean brand showcased a real determination to compete in the premium wireless space with the previous Galaxy Buds 3 Pro, and now hopes to go one further with its fourth-gen follow-up, the just-released Samsung Galaxy Buds Pro 4. This is the most almighty of challenges for the flagship buds, but if they can trouble the class leaders, we’ll know that Samsung has truly arrived on the premium wireless scene.

They’re not, however, cheaper than their Samsung rivals. The Galaxy Buds 4 Pro are very much a premium pair of earbuds, but their £219 / $249 / AU$399 tag sees them significantly undercut Sony’s flagships. The fourth-gen model didn’t see a price hike over their third-gen antecedents, either, which is a nice touch from Samsung.

Apple rip-offs this time around. The vertically placed ‘Blade Lights’ of the third-gen model have also gone, replaced by a sleek metallic stem covering which just gives the fourth-gen iteration a more premium aesthetic.

The Galaxy Buds 4 Pro have had their IP rating boosted from IP53 to IP57, granting protection against dust ingress and immersion in water up to a metre deep for around 30 minutes. That’s a more robust certification than the Sonys, which can only muster an IPX4 rating for general protection against splashes of water rather than full immersion.

Fit-wise, we generally find the Samsung earbuds comfortable and easy to get along with. The removable eartips are angled in slightly to allow for a more secure seal, with the stems helping to add a counterweight and keep everything locked into place. Samsung offers an ear-fit test via the companion Wearable app, confirming whether you’ve obtained an adequate seal with a quick scan of your ears.

Sadly, we feel let down that you only get three sizes of tip from which to choose, as the provision of small, medium and large options just seems so miserly for a pair of flagship wireless earbuds. We’d also note that some of our wearers struggled to keep the Samsung buds in place during more strenuous activities, so they may be less suited to running or sporting endeavours than more active-focused alternatives.

Touch controls on the Samsung Galaxy Buds 4 Pro are employed by a predominantly pinch-and-hold system, whereby you give the stems a squeeze to control operations such as playing and pausing tracks or switching noise cancelling modes, or swipe up or down on the exterior of the stem to increase or decrease your music’s volume.

Sony’s WF-1000XM6 rivals are a similarly bold departure from what came before, and the design is certainly distinct from the more traditional bud and stem design of the Galaxy Buds 4 Pro.

Open that rather chunky monolith of a charging case and you’ll see that Sony has altered both the look and the feel of the earbuds when compared to the outgoing model, sporting a more rectangular, boxy aesthetic.

Aside from improving noise cancelling and call quality (more on that later), the XM6s’ configuration is designed improve in-ear comfort, yet as we found during our testing, that might depend on who is using them.

That firm eartip material has returned for the sixth-gen iteration, and while it will suit some ears just fine, we still have multiple team members who simply cannot get to grips with how Sony’s latest buds fit inside their ears.

Sony does offer a handy air pressure fit test in the Sound Connect app, as well as four eartip sizes (extra small, medium and large) over the three offered by Samsung. Still, an extra large option wouldn’t have gone amiss for those users with larger ears, especially given how tricky the fit of the premium buds can be for some wearers.

Touch controls are on board for the XM6, and we’re pleased to report that we find them responsive and well-integrated during our tests. As is the case with the Buds 4 Pro, you can customise their configuration via their respective companion apps.

Decent, if not perfect, performances on both sides. We imagine that most users will find the Buds 4 Pro to be easier to get along with fit-wise, and they are more robust in terms of their IP rating, but they do lose a point for their meagre array of tip sizes.

iOS users get no app support at all.

For Sony users, you’ll be operating your WF-1000XM6 via the Sound Connect app (available for both iOS and Android), a platform which plenty of settings when it comes to the number of customisation options and device metrics it provides – including a the handy speak-to-chat mode, which lowers music volume when it recognises you are speaking to someone.

The Samsung buds provide support for the brand’s ‘360 spatial audio’ with head tracking, both of which require a Samsung device in order to work and can be toggled on or off via the accompanying app.

The tech works admirably, and unquestionably provides a more spacious and open experience than when listening in standard mode. Head tracking is also effective, even if it does suffer from the usual gripe of having a very slight delay whenever the sound moves from one earbud to the other.

For the XM6, support for Sony’s 360 Reality Audio is on the menu, aiming for a similar effect of granting a more immersive, three-dimensional soundfield. You will require a scan of your ears, as well as a compatible streaming service with these tracks (which are different from Dolby Atmos recorded tracks), such as Amazon Music Unlimited, to make use of the tech.

How about battery life? Samsung’s wireless flag-bearers grant seven hours from the buds and a total of 30 with the case when ANC is turned off. Switch noise cancelling on, and those numbers will drop to roughly six hours from the buds and a total of 26 hours with the case. By comparison, battery life for the WF-1000XM6 comes in at eight hours from the buds and a total of 24 hours with the case, with ANC on.

The Galaxy Buds Pro 4s’ big trump card comes via their compatibility with Samsung’s exclusive proprietary SSC UHQ hi-res codec, granting transmission of up to 24-bit/96kHz music files over Bluetooth via newer Galaxy devices.

We used a Galaxy S25 smartphone to get the most out of our test buds’ sonic capabilities, though we’re assured that the S24 and S23, as well as the newer generations of the Z Flip/Fold phones also offer compatibility with SSC UHQ.

Bluetooth support for the Sony WF-1000XM6 comes courtesy of standard SBC and AAC alongside Sony’s own LDAC codec for hi-res transmission up to 32-bit/96kHz, and you’ll also need a compatible source device in order to access it. Most Sony Xperia phones, such as the Xperia 1 VI and Xperia 1 VII, do offer LDAC support.

It’s a a close run thing on the general features front, with both pairs tending to match each other blow for blow when digging into their admirably large bags of tricks.

quad array of microphones in each earbud works to tremendous effect, isolating you from outside noise while putting speech to the forefront of any conversation. The Sonys also throw their Adaptive NC Optimiser into the mix, which automatically adapts the ANC algorithm to your fit and for the environment you’re listening in.

The resultant noise cancelling performance is exceptional. In full ANC mode, Sonys are superb at how naturally and subtly they isolate us from all kinds of exterior sounds, presenting us with a clean, rumble-free background through which our music can more easily shine when outdoors, on our commute or even on a plane.

Even when you sink to the noisy recesses of London’s underground network, the XM6 are able to dim down the low-end and midrange noise so they are much less intrusive.

A good effort from Samsung, but Sony is the clear winner here on both counts.

Good as the Galaxy buds are, the Sony WF-1000XM6 remain the benchmark-setters. Pitched in an even battle, the XM6 are a clear improvement over their rivals, as well as pretty much any other earbuds you’ll find at this level.

These are, by our measure, the best Sony buds yet. The WF-1000XM6 are as detailed and insightful as we’d expect, yet they also ooze a natural warmth and rich tonality which gives them immense appeal. If you found their predecessors just a touch analytical or dispassionate, that relative defect has been admirably rectified with the compellingly entertaining XM6.

Perhaps what we admire most about the WF-1000XM6 is their expressiveness and outstanding dynamic handling. The Sonys just sound so natural and believable as they tease out dynamic strands and fluctuations with remarkable insight and agility, giving music a three-dimensional, engrossing appeal that has us entranced no matter the tunes we play.

This is where the XM6 really distance themselves from their Samsung contemporaries, and while the Galaxy Buds 4 Pro are admirably spacious and clear, the Sony’s hugely expressive, authentic delivery makes them a considerably more involving option. For getting you to feel the heart and soul of your music, it’s the Sony buds every time.

The WF-1000XM6 are excellent across the frequency range, too. As we said in our review, they deliver “crisp highs all the way down to tightly controlled and textured lows”, and have “a grasp of bass notes and deliver layers of texture which the old model can’t quite replicate. The Sonys exhibit all the bass power and weight you could ask for, but it’s the way the notes are controlled and defined which really sets them apart from their rivals”.

Yes, the Galaxy Buds 4 Pros’ performance when making use of their specific Samsung SSC UHQ codec does narrow the gap somewhat, but it’s not enough to mask their relative limitations when put head-to-head with the best that Sony has to offer.

For sound performance, the WF-1000XM6 are in a class of their own.
