5 Cheap Harbor Freight Alternatives To Expensive Milwaukee Products

Published

on





If you want professional-grade power tools, you’re going to have to pay a premium price. At least, that’s how it goes with many of the top power tool brands. And of that bunch, few brands come with higher prices than Milwaukee. The brand certainly has its fans, but there’s no way around it: Milwaukee leverages its good reputation to justify charging high-end prices for its power tools. As tool prices climb across the industry, more and more people would probably appreciate a way to get Milwaukee power tool performance without Milwaukee power tool prices.

If that’s you, you might want to check out Harbor Freight. In recent years, this hardware store has greatly expanded its lineup of professional-grade equipment through its in-house brands like Hercules. In fact, their Hercules line is meant to compete directly with higher-end tools sold by brands like Milwaukee… all while keeping prices much, much lower than the big-name brands. To show you what we’re talking about, we’ve found five of the best Harbor Freight alternatives to Milwaukee’s more expensive versions.

1. Hercules random orbit sander

No matter if you’re doing some woodworking, a home renovation, or finishing a furniture project, you’re probably going to need to do some sanding. Cordless random orbit sanders are one way to do so. The Hercules 20V Brushless Cordless 5-inch Random Orbit Sander sells for $54.99 at Harbor Freight, which undercuts the price of the Milwaukee Tool M18 brushless 5-inch random orbit sander, priced around $149 at Home Depot.

And even with that cost difference, the Hercules model is still built with many of the same modern performance features expected of a Milwaukee-type tool. Its brushless motor gives you variable-speed control capable of delivering up to 12,000 orbits per minute. When paired with a Hercules 5 amp-hour battery or larger, the sander can deliver up to 40 minutes of continuous operation. The sander also includes an ergonomic rubberized grip to reduce vibration, and it uses an eight-hole dust collection system paired with a dust bag to help keep your work surface cleaner.

2. Hercules hammer drill/driver

Hammer drills are a cornerstone tool for both construction professionals and home renovators, especially when projects involve drilling into masonry, concrete, or other dense materials. And while Milwaukee has options for you (like the M18 FUEL hammer drill), you can expect to pay upwards of $229 at places like Home Depot. Meanwhile, Harbor Freight has the Hercules 20V Brushless 1/2-inch Compact Hammer Drill/Driver for $79.99 instead.

This tool can give you up to 1,200 inch-pounds of maximum torque, so you can drive large fasteners or drill holes into dense materials like it’s nothing. It’s also capable of up to 32,000 blows per minute in hammer mode. That rapid percussive action helps the drill break through concrete and masonry more efficiently than a standard drill ever could. Under typical conditions, Harbor Freight says the Hercules can drill up to 110 holes in concrete on a single charge.

3. Hercules trigger-grip angle grinder

Angle grinders are another popular power tool that people might look to Milwaukee for. For example, the 15-amp large-angle grinder from Milwaukee Tool sells for $299 at Home Depot. Compare that to the Hercules 15-amp 7-inch/9-inch Trigger-Grip Angle Grinder going for $129 at Harbor Freight. That’s more than 50% savings if you’re willing to swap the popular red tool for this lesser-known blue one.

The Hercules grinder is powered by a 15-amp motor that can produce speeds up to 6,500 revolutions per minute. You also get a trigger-grip handle for more leverage and control compared with traditional side-handle-only grinders. The handle includes an optional lock-on function that lets the tool run longer without you constantly applying pressure to the trigger. The Hercules grinder also includes tool-free guards for both 7-inch and 9-inch grinding wheels. It’s all protected by an all-metal aluminum gear case with a reinforced plastic housing to reduce that annoying vibration.

4. Hercules reciprocating saw

Reciprocating saws are a must-have for demolition, remodeling, or rough-cutting applications. Milwaukee’s M18 FUEL reciprocating saw costs $249 at Home Depot. That’s not the brand’s most expensive power tool, to be clear, but it’s still not cheap. The Hercules 20V Brushless Cordless Reciprocating Saw, however, is priced at $79.99 at Harbor Freight, which is quite a steep price drop.

The saw can deliver up to 3,000 strokes per minute via its variable-speed trigger. It also uses a pivoting shoe with three depth adjustment positions to give you more control over the cut. (Beyond the extra control, adjusting the shoe means extending the blade life by exposing different parts of the blade during repeated cuts.) Blade changes are nice and easy thanks to a keyless single-action mechanism that lets you swap things out without any additional tools. The reciprocating saw also includes a super safe electric brake that stops the blade immediately after the trigger is released.

5. Hercules right angle drill

Right angle drills are great for working in those tight spaces where traditional drills just won’t fit. But if you want one from Milwaukee, you’ll have to pay $329 for it at Home Depot. On the other hand, Hercules can get you a 20V Brushless Cordless 1/2-inch Variable-Speed Right Angle Drill for only $94.99 at Harbor Freight. It’s one of the most dramatic differences between Milwaukee and Hercules pricing that we’ve seen.

It comes with a variable-speed trigger for adjustable drilling speed based on the material you’re drilling. (That’ll also help prevent the drill from overheating and avoid any bit damage that can come from switching between softer materials and denser wood or construction lumber.) It also includes a built-in LED work light that shines on the drilling area. All in all, you’re looking at more than 120 holes drilled per battery charge. Combine that with the fact that it’s a third of the price of the Milwaukee version, what’s not to like?

Elon Musk announces Terafab project he claims will be the ‘largest chip manufacturing facility ever’

Published

on

Elon Musk has announced the Terafab project, a joint venture between Tesla, SpaceX and xAI, to build the “largest chip manufacturing facility ever.” In his usual grandiose fashion, Musk claims Terafab is the next step towards harnessing the power of the sun and creating a “galactic civilization.”

Musk, CEO of all three companies, announced plans for the Terafab in a livestream on X. As the name implies, the project’s ultimate goal is to produce a terawatt of computing power each year so that it can match the companies’ growing demand for chips. Musk explained during the livestream that he’s grateful to existing supply chain partners like Samsung, TSMC and Micron, but the current capacity of chip manufacturers only adds up to about two percent to what Tesla and SpaceX needs in terms of future computing power needs.

“We either build the Terafab or we don’t have the chips,” Musk said during the event. “And we need the chips so we’re going to build the Terafab.”

The Terafab project, estimated to cost at least $20 billion, will start with the Advanced Technology Fab in Austin, Texas, where Tesla is already headquartered. Musk said that the two types of chips will be produced in the Terafab: one for terrestrial purposes, like to power Full Self-Driving or Optimus robots, and another more high-powered, durable chip to be used in space. If you’re wondering what Musk has in store for space, the SpaceX CEO filed an application with the Federal Communications Commission to launch a million satellites to create an “orbital data center” earlier this year. As promising as this sounds, it’s worth noting that Musk has previously overpromised and underdelivered on other projects, like the Hyperloop, a $40,000 Cybertruck and fully autonomous driving.

Cursor admits its new coding model was built on top of Moonshot AI’s Kimi

Published

on

AI coding company Cursor launched a new model this week called Composer 2, which it promoted as offering “frontier-level coding intelligence.” 

However, an X user posting under the name Fynn soon claimed that Composer 2 was “just Kimi 2.5” with additional reinforcement learning — Kimi 2.5 being an open source model recently released by Moonshot AI, a Chinese company backed by Alibaba and HongShan (formerly Sequoia China). 

As evidence, Fynn pointed to code that seemed to identify Kimi as the model.

“[A]t least rename the model ID,” they scoffed.

Advertisement

It was a surprising revelation, since Cursor is a well-funded U.S. startup that raised a $2.3 billion round last fall at a $29.3 billion valuation, and is reportedly exceeding $2 billion in annualized revenue. Also, the company didn’t mention anything about Moonshot AI or Kimi in its announcement.

However, Cursor’s vice president of developer education Lee Robinson soon acknowledged, “Yep, Composer 2 started from an open-source base!” But he said, “Only ~1/4 of the compute spent on the final model came from the base, the rest is from our training.” As a result, he said Composer 2’s performance on various benchmarks is “very different” from Kimi’s.

Robinson also insisted that Cursor’s use of Kimi was consistent with the terms of its license, a point the Kimi account on X repeated in a subsequent post congratulating Cursor, where it said Cursor used Kimi “as part of an authorized commercial partnership” with Fireworks AI.

“We are proud to see Kimi-k2.5 provide the foundation,” the Kimi account said. “Seeing our model integrated effectively through Cursor’s continued pretraining & high-compute RL training is the open model ecosystem we love to support.”

So why not acknowledge Kimi upfront? Beyond any potential embarrassment in not creating a model from scratch, building on top of a Chinese model might feel particularly fraught right now, with the so-called AI “arms race” often framed as an existential battle between United States and China. (See, for example, Silicon Valley’s apparent panic after Chinese company DeepSeek released a competitive model early last year.)

Cursor co-founder Aman Sanger acknowledged, “It was a miss to not mention the Kimi base in our blog from the start. We’ll fix that for the next model.”

Europe’s top funding rounds this week (16 -22 March)

Published

on

A quieter week by headline standards, but one that reveals a great deal about where European venture capital is quietly concentrating: AI agents for physical industries, agritech automation, and the growing operator-to-VC pipeline.


What the week of 16-22 March delivered was something different in texture rather than volume: smaller rounds, more specific theses, and a pattern of investment that points more clearly at where European capital is actually building conviction. AI agents entering complex physical environments.

Agricultural automation that finally has the engineering to match its ambitions. A new generation of European VC funds drawing on operators who have scaled the continent’s own companies.

1. Upvest – $125M Series D | Berlin, Germany

Upvest has raised $125 million just a year after its last round, pushing its valuation to €640 million from €360 million.

The company says its system helps biotech teams unify fragmented trial data, surface insights, flag anomalies, and manage operational risks in regulated environments. The round follows a €3 million seed in 2024 and marks a bigger bet on AI tools that do more than store data.

6. Kupando – €10M Series A | Schönefeld, Germany

Kupando has added €10 million to its Series A, bringing the round to €23 million as it pushes its lead drug, KUP101, into a Phase 1b trial. The German biotech is developing an innate immunity therapy for advanced solid tumours and drug-resistant infections, a less crowded path in immunotherapy.

The funding suggests investors believe the science is finally ready to move from preclinical promise into patients.

7. eternal.ag – €8M seed | Cologne, Germany

Eternal.ag, a greenhouse robotics startup founded by former Honest AgTech co-founder Renji John, has raised €8 million. Based in Cologne and Bengaluru, the company is building autonomous harvesting systems for greenhouses, starting with tomatoes.

10. Reson8 – €5M pre-seed | Amsterdam, Netherlands

Reson8, an Amsterdam startup building speech AI for Europe’s linguistic complexity, has raised a €5 million pre-seed round led by Balderton Capital.

The company’s platform supports more than 20 European languages and adapts to industry jargon, accents, and speaking patterns without retraining. Its focus is on high-precision sectors such as healthcare, logistics, legal, and finance.

11. BBLeap – €5M | Rijen, Netherlands

BBLeap, a Dutch agritech startup focused on precision spraying, has raised €5 million in a round led by ESquare Capital, with backing from Yield Lab Europe and existing investors.

Do you want to build a robot snowman?

Published

on

Nvidia’s GTC conference had everything: trillion dollar sales projections, graphics technology that can yassify video games, grand declarations that every company needs an OpenClaw strategy, and even a robot version of the beloved snowman Olaf from Disney’s “Frozen.”

On the latest episode of TechCrunch’s Equity podcast, TechCrunch’s Kirsten Korosec, Sean O’Kane, and I recapped CEO Jensen Huang’s keynote and debated what it means for Nvidia’s future. And yes, a big part of our discussion focused on poor Olaf, whose microphone had to be turned off when he started rambling.

Even if the demo had gone flawlessly, Sean might still have had some reservations, as he noted these presentations always focus on “the engineering challenges” and not the “really messy gray areas” on the social side.

“But what happens when a kid kicks Olaf over?” Sean asked. “And then every other kid who sees Olaf get kicked or knocked over has their whole trip to Disney ruined and it ruins the brand?”

Read a preview of our conversation, edited for length and clarity, below.

Anthony: [CEO Jensen Huang] was basically saying that every company needs to have an OpenClaw strategy now. I think that is just a very grand statement that’s meant to be attention grabbing; I think it’s also interesting coming at this kind of transitional moment for OpenClaw. 

The founder has gone to OpenAI. So it’s now this open source project that potentially can flourish and evolve beyond its creator, or it could languish. If companies like Nvidia are investing a lot into it, then [it’s] more likely that it’ll continue to evolve. But it’ll be interesting to see a year from now, whether that looks like a prescient statement or everyone’s like, “Open what?”

Kirsten: In the case of Nvidia, it costs them nothing in the grand scheme of things to launch what they call NemoClaw, which is an open source project, which they built with the OpenClaw creator. But if they don’t do something, they have a lot to lose. So really that message to me, the way I translated it when Jensen was like, “Every enterprise needs to have an OpenClaw strategy,” it was, “Nvidia needs to have a solution or strategy for enterprises, because if it’s successful, it is another way or another pathway for Nvidia to be part of numerous other companies.” So doing nothing is a greater risk than doing something that doesn’t go anywhere.

Advertisement

Sean: The real question here is why have we not talked about what is clearly the end game for Nvidia, and the thing that is going to turn it into the first $100 trillion company, which is an Olaf robot.

Anthony: How could I forget?

Kirsten: Anthony, just go to the end of the two and a half hours to watch this.

So, the Olaf robot comes out, and this is something that Jensen loves to do. He loves to have these demos and some of them go better than others. It is also to demonstrate Nvidia’s technology in robotics, and I don’t know if Olaf was actually speaking in real time or if it was programmed — it felt a little programmed, or it had specific keywords that it used.

Advertisement

But the greatest part about it is that they had to cut its mic at the end because it just started rambling and speaking to the crowd. And then it went over to its little passageway and was slowly lowered. And you could see it on the video. It was still talking, but no mic.

Sean: Now we just need to give this little robot a wheelbase. And I know the perfect founder who can provide it. 

I mean, these demos are always silly. I don’t want to get up on my soapbox, because I know that we’ve talked about this a little bit earlier this week, but this was an impressive demo up until the moment where it fell a little bit short.

This is another really good example, though, of [how] robotics is a really interesting engineering problem and a really interesting physics problem and a really interesting integration problem, and all of this stuff, but this was presented as, in partnership with Disney, and it’s supposed to be the future of Disney parks and things like that: You’re going to be able to walk around and see Olaf from “Frozen” and take pictures of them and everything.

Advertisement

But these efforts never consider — or certainly don’t put front and center in events like this — all the other things you have to consider when you roll stuff out like this. There’s a really good YouTuber, Defunctland, that did a really good video about this — four hours long, not too long — about the history of Disney trying to get these kinds of robotics into their park, these automatons.

The engineering challenges are really interesting and it’s fun to see that history, but it always comes back to the same question of: Okay, but what happens when a kid kicks Olaf over? And then every other kid who sees Olaf get kicked or knocked over has their whole trip to Disney ruined and it ruins the brand?

There’s just so much on the social side of this. And that sounds silly, but this is the question that we’re kind of asking about humanoid robots, too. There’s so much hype about all this other stuff and we just don’t really hear as much conversation about the really messy gray areas on the social side of these things, and also just integrating them into people’s lives. We only ever really hear about the engineering challenges — which again, are really impressive.

Kirsten: I have a counterpoint and then we have to get to our next [topic]. This is a job creator, because Olaf will have to have a human babysitter in Disneyland, probably dressed up as Elsa or something else. You can imagine that actually, what we’re doing is creating jobs [with] this engineering experiment.

Watch this moonwalking humanoid robot impress with lifelike agility

Published

on

A new video (above) out of South Korea features the field tests and interaction capabilities of KAIST Humanoid v0.7, developed at the Korea Advanced Institute of Science and Technology (KAIST).

The impressive humanoid robot was developed at KAIST’s Dynamic Robot Control & Design Laboratory (DRCD) and deploys actuators and other technology that was developed in-house.

In the video below, you can watch the bipedal bot walk, jog, and jump in an incredibly human-like way. It also shoots a soccer ball toward a goal (disappointingly there’s no robot goalkeeper there to challenge it), and performs a perfect moonwalk along astroturf. And it was the moonwalk that created a bit of a buzz in the comments accompanying the video.

“Moonwalk was flawless,” wrote one, while another commented, “Okay all of this was impressive, but you convinced me with the moonwalk.”

Advertisement

In its robotics work, KAIST deploys Physical AI, a form of AI technology that enables machines to understand and act in the physical world, helping to explain why robots such as the KAIST Humanoid v0.7 appear to move in such a human-like manner.

Instead of just “thinking in words” like typical AI, Physical AI gives machines a sense of space and timing in real environments.

Under KAIST’s broader collaborative intelligence initiative led by Young Jae Jang, the approach trains robots and systems to learn continuously through simulation and real time feedback, rather than relying only on enormous historical datasets.

Essentially, Physical AI merges brain and body by tightly integrating software intelligence with hardware such as motors and sensors so that the machines do not only compute, but also act, react, and collaborate in complex environments, whether as part of fully automated factories or in humanoid robots doing something like kicking a ball.

Advertisement

Engineers are refining the KAIST Humanoid v0.7 with the aim of enhancing its mobile and dexterous capabilities, thereby building on its existing walking and dynamic movement skills. By further integrating AI with mechanical hardware, it plans to get the robot to perform more complex tasks like carrying items or operating machinery, bringing Physical AI to real-world humanoid robot applications.

KAIST is one of South Korea’s top universities and is often compared to top global tech schools like MIT in the U.S. Founded in the early 1970s to drive Korea’s scientific and technological growth, KAIST focuses heavily on research in fields such as AI, robotics, physics, and engineering.

    Clearer calls with Samsung smartphones

Introduction

Every year there’s a new Samsung Galaxy smartphone, and more often than not, alongside them is a new pair of headphones – in this case, it’s the Galaxy Buds Pro 4.

The Galaxy Buds Pro 4 don’t receive as much fanfare as the smartphones (in this case the Samsung Galaxy S26 Ultra), less the headline and more a sub-header; but similarly to how Apple approaches its true wireless pairs, the Galaxy Buds are a partner to the smartphones rather than an entity that exists on its own.

Advertisement

The Galaxy Buds have been getting better – aside from the strange burst of designs a few years ago – are these the best yet?

Advertisement

Design

  • Plush level of comfort
  • IP57 rating
  • White, black and pink gold finishes

Samsung has toned down the AirPods-vibe though, at the end of the day, these are a pair of stem-based wireless earbuds – there’s not much you can do with the actual design.

But Samsung has tried and the Galaxy Buds 4 Pro do look nice, the silver ‘real metal blade’ finish of the stem feels suitably premium. Comfort levels are very good. I’ve worn these for hours and not felt any discomfort. Small, medium and large ear tips are provided, with medium as default.

I do, however, find that the seal for these earbuds can come loose while walking. Even munching on food can cause the fit to loosen and require a push back in.

Samsung continues with gesture/pinch controls. I’ve never been a big fan and I can’t say the Galaxy Buds 4 Pro have persuaded me to think otherwise. I find it fiddly, and often when I’ve tried to play/pause a track I’ve ended up lowering the volume. I often just use the controls in-app than use the onboard controls – it’s much easier for me.

The charging case differs from the Galaxy Buds 3 Pro and is different from the Galaxy Buds 4 launched alongside the Pro version. Compared to the 3 Pro, this new case is more compact but also slightly taller – the see-through case is a nice visual touch. Rated at IP57, these earbuds put out a stiff hand against water, dirt and dust (more so than most premium true wireless), though the case doesn’t sound like it has any protection.

Colours come in white and black, but buy directly from Samsung and there’s the option of a Pink Gold (which looks like it costs the same).

Noise-Cancellation

  • Galaxy AI-supported features
  • 26 hours battery life with ANC
  • Galaxy Wearable app for customisation

In general, the Galaxy Buds 4 Pro’s adaptive noise-cancellation is good, very good even, especially in terms of how consistent the performance is.

Whether I’m on the Victoria Line, a train, a bus, an aeroplane, the DLR or walking outside with traffic going past, the level of quiet and calm has always been very high. The barometer I have with ANC headphones is whether I need to raise the volume to mask more noise and I never felt the need to do that with the Galaxy Buds 4 Pro.

Cars are reduced to hums, the Underground is no longer a constant noise machine, and compared to the Galaxy Buds 3 Pro, these do thin out noise better.

But against the Sony WF-1000XM6, Bose QuietComfort Ultra Earbuds 2 and Technics EAH-AZ100, they’re just a step beyond the Samsung, with more noise peering in when wearing the Galaxy Buds 4 Pro during a pink noise test. They’re not too far off though.

The transparency mode sounds clear – big and broad in terms of what you can hear, and it sounds natural enough, though again perhaps not to the same levels of Sony and Bose produce.

Call quality is very good. With Samsung Galaxy phones there’s a Super Clear Call feature that enhances clarity and reduces noise, but even using a OnePlus smartphone the performance was very good.

Background noise was reduced and though my voice did sound muffled – at times it was hard for the other person to hear some words – but overall the performance is good for use when you’re outside.

Features

  • Galaxy smartphone exclusive features
  • Wear app for non-Galaxy smartphones

The Galaxy Buds 4 Pro aren’t short of features, though you’ll need to have a Galaxy smartphone to get the most out of them, especially one that’s been updated to the One UI 8.5, as that has access to features not present in previous versions.

Like with Apple’s AirPods, the Galaxy Buds’ UI is built into the Samsung smartphone UX, but for everyone else, you’ll need to download the Galaxy Wear app.

Wirelessly there’s Bluetooth 6.1, which brings some enhancements over Bluetooth 5 (everything is just better, in simple terms), and I’ve found the connection to be strong wherever I am (and that’s without a phone that supports Bluetooth 6). Instability and interference have barely been an issue.

The headphones support an interesting array of codecs for the Bluetooth fans out there, with SBC, AAC, LC3, and Samsung’s own SSC and SSC-UHQ, the latter acting as Samsung’s high quality codec of choice against Sony’s LDAC and Qualcomm’s aptX. SSC is only available on Samsung Galaxy phones though.

You can toggle it on in the app/settings and it lets loose 24-bit/96kHz audio over a Bluetooth connection – though don’t take that to mean it’s lossless. It’s very likely to be lossy (which means detail is lost).

There’s 360 Audio with Head Tracking that builds on top of immersive audio formats such as Dolby Atmos music. The head tracking works well when listening to Sarah Kinsley’s Truth of Pursuit and Brent Faiyaz’s Other Side on Tidal, but there’s possibly the slightest lag when moving my head and waiting for music to respond.

Otherwise, I’m rather impressed in terms of clarity – immersive audio tends to sound less detailed and softer but the Galaxy Buds 4 Pro do a good job of keeping clarity levels high.

There are Head Gestures for accepting and rejecting calls (just added to One UI 8.5). and Earbud fit test (much less annoying than the Sony Sound Connect version): customisation of controls, battery life indicators and swapping through noise-cancelling modes, EQ options and Audio Broadcast (Auracast by another name). There are voice controls (mainly through Bixby) and accessibility controls if needed.

Want to translate words from a different language? You can read a transcript of what the earbuds hear, translated to your language via Galaxy AI, speaking of which, Samsung seems to have calmed down the AI narrative and rightly so. I don’t need to be told about AI, I just need it to work in the way it’s meant to.

You can switch to nearby devices without having to jump into pairing mode, though the fine print indicates these need to be connected to your Samsung account. With that in mind, Bluetooth multipoint is a slight mystery in that it is supported (with Samsung devices) and isn’t (with anything other than Samsung). I can’t have the Galaxy Buds 4 Pro connected to a Galaxy smartphone or OnePlus model at the same time.

Lose the earbuds and you can locate them through Samsung Find, although it seems to think I’m not in my house but next door – close enough I suppose. The Adapt Sound feature is not what I initially thought it’d be. It tunes the sound for how old you are, boosting frequencies based on your age. You can add a personalised sound profile by going through audio tests to determine your hearing.

Battery Life

  • Six hours per charge
  • Wireless charging

Samsung claims the Galaxy Buds 4 Pro are capable of six hours with ANC on, which doesn’t sound the most progressive (and isn’t), with a total of 26 hours with the charging case (without ANC it’s 7 and 30 hours).

Perhaps Samsung have erred on the safe side but I’ve found battery life pretty strong. An hour’s listening saw both earbuds fall to 87%, which would put the Galaxy Buds 4 Pro at around 8 hours, not six.

There’s fast-charging for those in a fix, and wireless charging support as well.

Sound Quality

  • Clear, detailed, spacious sound
  • Wide soundstage
  • Balanced, warm approach

Not too dissimilar to the Galaxy Buds 3 Pro, the Galaxy Buds 4 Pro feature a two-way speaker that’s been redesigned from before.

There’s now a wider woofer alongside a precision tweeter, with the aim of delivering deep, textured sub-bass to extended highs with a “faster transient response, a rich midrange body and sharp detail”. Each driver has its own amplifier, which should lead to reduced distortion.

Paired with a non-Galaxy smartphone and the results are… fine. The Galaxy Buds 4 Pro sound on the rich side but the bass isn’t the most assertive, the highs don’t come across as the brightest and they’re not the most dynamic or energetic sounding pair I’ve ever heard.

Some of the traits carry over when paired to a Galaxy smartphone, but to unlock the highest level of performance from the Galaxy Buds 4 Pro, you need to toggle on the SSC-UHQ feature. With that, these earbuds ascend to a higher level.

Which is not to say they match the Sony WF-1000XM6, which beat the Galaxy Buds 4 Pro for insight, detail and energy, but they have qualities of their own that aren’t to be dismissed.

The soundstage is very wide. Bass never hogs the limelight but I’d vote for having a bit more depth and energy to the low frequencies. With a track like Hard Life’s Skeletons, the bass performance leaves me wanting a bit more in terms of energy.

But it’s the clarity of these earbuds that impresses, as well as the natural tone they strike whether it’s with more upbeat K-pop tracks like ILLIT’s Magnetic or slower, more downtempo tracks like Amy Winehouse’s Back to Black – the wide soundstage, crisp tone to highs and levels of insight and detail with vocals stand out.

Andreas Ihlebæk’s Come Summer is a track I play to try and catch headphones out – the highs sound bright, but it can expose a lack of precision and detail, sounding soft and almost too bright if headphones get it wrong. The Galaxy Buds 4 Pro stay on the right side of balanced, bringing brightness and variation to the highs while maintaining higher levels detail and clarity.

However, are the Galaxy Buds 4 Pro better sounding than the Galaxy Buds 3 Pro? Initially there’s a question mark around that. The approach both take is similar but the Galaxy Buds 4 Pro eke out a little more insight and detail from tracks, administering a slightly more natural tone. It isn’t enough to necessarily trade the older model for the newer ones, but if you’re coming from the Galaxy Buds 2, this level of sound is a jump up

Should you buy it?

No Samsung Galaxy phone? Then much like with the Galaxy Buds 3 Pro, there’s not much point even glancing at these headphones.

Final Thoughts

I had to have a good think in terms of how to approach the scoring for these headphones. They are better paired with a Galaxy smartphone, in particular the Ultra series, and the way Samsung markets these headphones, there’s little reason to buy them if you’re not a Galaxy owner.
 
So the score relates to the experience you’d get with a Galaxy smartphone, much like AirPods work best with an iPhone.
 
The Galaxy Buds 4 Pro sound good, they could be a little more bolder and exciting but I’ve enjoyed them. It’s not quite Sony WF-1000XM6 or Status Pro X level, but for Samsung owners with the SSC-UHQ codec enabled, they’re a good listen.
 
The noise-cancelling impresses, the fit is comfortable, battery life is solid and the call quality is good. Overall, this is a strong effort from Samsung, and their best true wireless earbuds yet.

From Sydney to South Lake Union: VR startup Vantari brings its ‘flight simulator for healthcare’ to Seattle

Published

on

Vantari, a virtual reality startup that builds “flight simulator” software for doctors and nurses, has officially moved its headquarters to Seattle as it ramps up work with health systems and device makers across North America.

CEO and co‑founder Nishanth Krishnananthan relocated from Australia to Seattle two years ago and recently officially established the company’s headquarters in the Emerald City.

The inspiration for Vantari came from his own experience as a surgical doctor in Australia and seeing how poorly procedural training prepared clinicians for real emergencies. He wondered why healthcare didn’t use the same training tactics as the aviation industry.

Founded in 2017, Vantari now works with more than 50 organizations in North America, Australia, and the UK. Customers include major academic medical centers such as Harvard, Yale, and Mount Sinai, and the company has established new “centers of excellence” with Seattle University and the University of Washington’s anesthesiology department.

Hospitals and universities use off‑the‑shelf Meta/Oculus headsets connected to laptops. Clinicians log in, select their specialty and procedure, and then perform the steps in a fully virtual environment mapped to college and best‑practice guidelines. An AI facilitator inside the headset guides users step‑by‑step, answers questions, and scores performance, while supervisors can later review the logged session data.

VR controllers mimic the feel of inserting catheters, puncturing tissue, and adjusting equipment. Vital signs change dynamically in response to each action.

The company has a library of procedures, ranging from anesthesia to critical care to cardiology. It has also patented an ultrasound system inside VR that allows trainees to perform imaging and guidance as part of the procedure. Many scenarios are co‑developed with device makers such as Boston Scientific, JNJ, and Sonosite.

Vantari’s VR software includes an ultrasound system that allows users to perform imaging and guidance during a mock procedure.

Vantari’s business runs on a B2B SaaS model, offering annual licenses and hardware bundles. Vantari also signs contracts with medical device and pharmaceutical companies, which co‑develop modules on the platform and design virtual versions of their devices. A third revenue stream comes from industry and accrediting bodies that co‑develop content.

To date, Vantari has raised about $7 million, largely from Australian VCs, family offices and high‑net‑worth doctors and physicians. Last year it raised $2 million from Seattle‑area backers SpringRock VC and Alliance of Angels.

Krishnananthan said the move to Seattle makes it easier to serve U.S. customers and attract additional capital from American investors. He also pointed to the strength of local tech giants and medical institutions — including Amazon, Microsoft, Seattle University and the University of Washington — as well as nearby medical device firms.

The team is roughly 18 people, split about 50/50 between Australia and the U.S., with most employees working remotely.

Looking ahead, Vantari wants to go beyond static content and is building an AI scenario builder that would let hospitals generate their own protocols and procedures on the platform. Krishnananthan’s long‑term vision is to use the interaction data it collects to create what he calls a “Google Maps of surgery,” offering live, mixed‑reality guidance during real procedures so clinicians receive step‑by‑step support at the bedside, rather than just training in a headset.

“That’s like the big North Star that I want to get to,” he said. “It’s a lot more accessible now with the technology advancements that are happening.”
