The best earbuds we’ve tested for 2025

The best earbuds we’ve tested for 2025

It’s hard to buy a bad pair of wireless earbuds these days, and with constant discounts and deals wherever you look, now is as good of a time as any to splurge on the pair you’ve been eyeing. The market has come a long way since the early era of true wireless earbuds when we had to deal with mediocre sound quality and unreliable performance, all for the sake of ditching cables. Things are much different now. After several product generations of learned lessons, companies like Sony, Apple, Samsung, and others are releasing their most impressive earbuds to date.

You can get phenomenal noise cancellation and sound quality in the premium tier of earbuds if you’re willing to spend big. But those aren’t always the most important criteria for everyone: maybe you’re looking for the perfect fitness earbuds or for a set that works just as well for Zoom calls as for playing your favorite playlists and podcasts.

Tech companies are increasingly making their earbuds work best with their own products through exclusive features and functionality, so that’s another thing to consider as you shop around. If you want a perk like head-tracking spatial audio, you’ll need to use AirPods with an iPhone, Samsung buds with a Samsung phone, and so on.

With dynamic, rich sound and the best ANC available, the QC Ultra Earbuds are a terrific pick if you want to listen to your music in peace.

What I’m looking for

Whether you’re using earbuds to check out a newly-released album on Spotify, as motivation at the gym, or to tune out distractions around the office, they must deliver on the key metrics of sound quality, noise cancellation, voice call performance, and more. We spend many hours putting our picks through the paces. This includes quiet listening sessions that reveal their full detail, overall fidelity, and dynamics. We also take these buds out into the real world — on rush hour subway commutes, around busy cities, and in crowded cafes — to gauge their connection strength and determine how effectively they can quiet the world around you. We test them on video calls at work and by calling friends and family, who provide blunt feedback on how their mics sound. And importantly, with earbud makers often reserving certain software tricks for their own preferred ecosystem, we see how the earbuds fare when used across multiple platforms.

No matter how they sound, what good are earbuds if you don’t enjoy wearing them? Ears come in all shapes and sizes, so the comfort factor is highly subjective. Most of our picks include several sizes of ear tips; usually they’re silicone, but some companies use foam (or both). Again, which you like better comes down to personal preference. Silicone tips are more common, but foam can expand to fill more of your ear for a better seal. The most important tip I can offer is to try different-sized tips in each ear: you might find that one of your ears needs something bigger or smaller than the other.

Just like with comfort, we all have our own inclinations for what we want from sound quality. Some people are bass-heads who can’t live without a thumping low end. Personally, I care more about dynamics, clarity, and definition from the music I’m listening to. I want vocals to ring through naturally and instruments to be well separated in the sound stage. I look for earbuds that can bring out the subtle details in my favorite songs.

What was once a luxury feature is now the status quo. Many of our top picks include active noise cancellation to help quiet the raucous outside world. Whether you’re trying to concentrate at the office or rest while traveling, noise cancellation can be a huge help. However, some people hate the “plugged up” feeling of earbuds and prefer open-style buds that help maintain full awareness of their surroundings.

Most earbuds these days can reach between five and six hours of continuous battery life with ANC enabled. Some models can exceed that (and over-ear headphones tend to last much longer on a charge), but the convenience of being able to just pop your earbuds back into their case for more juice makes the tradeoff easier to live with.

Even if you don’t intend to use your earbuds for fitness purposes, there’s always a chance of getting caught out in the rain while wearing them. At minimum, you should be looking for earbuds that offer IPX4 water resistance. This safeguards them from splashes of water (and sweat), so they should be cut out for the hazards of daily life.

The best overall wireless earbuds

$248

The Good

  • Smaller, more comfortable design
  • Upgrades to ANC and sound quality
  • Much clearer voice call performance

The Bad

  • Glossy texture can make them harder to remove from case
  • Sony’s bonus features aren’t as seamless as those of its competitors
  • Potential battery longevity concerns

Noise cancellation: Yes / Battery life: 8 hours (ANC on) / Water resistance: IPX4 / Bluetooth codecs: LDAC, AAC, SBC / Multipoint: Yes / Works best with: Android, iOS, Windows, macOS / Ear tips: Foam (XS, S, M, L)

Just like their predecessors, Sony’s WF-1000XM5 earbuds have again topped our recommendations for the overall best noise-canceling earbuds. Thanks to their larger drivers, the audio quality is more detailed and dynamic than before while still retaining the warmth and clarity that made the WF-1000XM4 so enjoyable. Sony has also further improved its ANC and is nearing the same territory as Bose’s QC Earbuds II. These earbuds do a terrific job of eliminating background noise. Battery life can stretch to eight hours of continuous listening with noise cancellation turned on.

Some people found the XM4 to be bulky and uncomfortable, so this time around, Sony has managed to shrink the XM5 by 25 percent. Like before, the company includes foam-style tips that expand in your ears to create an excellent seal — and now there’s a fourth (extra small) set of tips in the box.

On Android phones, the 1000XM5 support Sony’s LDAC codec for higher-quality music playback. And they’re capable of dynamic head tracking spatial audio through supported video apps like Netflix. But even if you’re not using LDAC (or have an iPhone), these are up there with the very best audio-focused premium earbuds — including Sennheiser’s Momentum True Wireless 4, only with substantially better noise cancellation. They’re also capable of multipoint Bluetooth connectivity, so you can pair them with two devices at the same time.

It’s worth noting that there were many reports of battery issues with the 1000XM4 over time as those earbuds aged, but Sony claims to have rectified that problem with the new model by tweaking the charging algorithm.

$79

The Good

  • Standout color and design
  • Very compact carrying case
  • Great performer for the price

The Bad

  • Limited retail availability
  • Plastic case can show scuffs

Noise cancellation: Yes / Battery life: 5.5 hours (ANC on) / Water resistance: IP54 / Bluetooth codecs: LDAC, AAC, SBC / Multipoint: No / Works best with: Android, iOS, Windows, macOS / Ear tips: Silicone (S, M, L)

When looking at Nothing’s Ear (a) earbuds, it’s easy to focus all your attention on the catchy yellow color or their fun, super compact carrying case. But at their $99.99 price, the company’s entry-level earbuds provide a ton of features, including active noise cancellation, a low-latency mode for gaming, multipoint Bluetooth pairing, and a decent IP54 dust and water resistance rating.

And the sound quality you get outperforms my usual expectations for this price point. They’re not quite on par with Nothing’s higher-end Ears, but you do get expressive, very enjoyable audio — and you can customize the EQ further in Nothing’s mobile app.

The best noise-canceling earbuds

$285

The Good

  • Most powerful ANC you’ll find in earbuds
  • Lively, rich sound
  • Stabilizer fins are easier to apply

The Bad

  • Immersive Audio drains battery
  • Still no multipoint in 2023
  • Wireless charging requires $49 case

Noise cancellation: Yes / Battery life: 6 hours (ANC on) / Water resistance: IPX4 / Bluetooth codecs: AAC, SBC, aptX Adaptive / Multipoint: Yes / Works best with: Android, iOS, Windows, macOS / Ear tips: Silicone (S, M, L)

Bose’s QuietComfort Ultra Earbuds are the most powerful noise-canceling earbuds on the market. Of all our top picks, they do the best job at offering peace and quiet from the cacophony of daily life and putting you in a private bubble with your music playlists or favorite podcasts.

A photo of Bose’s QuietComfort Ultra Earbuds.

The QC Ultra Earbuds are extremely similar to 2022’s QC Earbuds II in terms of design, fit, and sound. Audio quality is rich and dynamic, delivering more bass thump than, say, Apple’s AirPods Pro. And by switching to a two-piece ear tip / stabilizer fitting process, Bose’s latest flagship buds should fit a wider range of ears more comfortably. The Ultra also introduce a new Immersive Audio mode, which is Bose’s take on spatial audio.

The best earbuds for sports and working out

$249

The Good

  • Huzzah! Wireless charging!
  • Adds ANC, transparency modes, spatial audio
  • Slimmer ear hook, smaller case
  • Adds heart rate
  • Great sound
  • No price hike

The Bad

  • Case is still a chonker
  • Heart rate is not that useful for iOS users

Noise cancellation: Yes / Battery life: 8 hours (ANC on) / Water resistance: IPX4 / Bluetooth codecs: AAC, SBC / Multipoint: No / Works best with: Android, iOS, Windows, macOS / Ear tips: Silicone (XS, S, M, L, XL)

After a long wait, Beats finally introduced the Powerbeats Pro 2 in early 2025. They carry forward the signature ear hook design of past Powerbeats earbuds, but improve upon the original Powerbeats Pro in several key ways. Beats added active noise cancellation and a natural-sounding transparency mode to the Pro 2; the first-generation pair lacked both. The earbuds themselves are lighter, too, and the charging case is noticeably smaller.

The Powerbeats Pro 2 also feature heart rate monitoring thanks to built-in sensors on each earbud. You might already have a fitness tracker, chest strap, or smartwatch for this purpose, but if not, you can use these with compatible apps like Nike Run Club, Runna, Ladder, Slopes, Open, Peloton, and YaoYao. The downside is that they can’t simultaneously play music and broadcast heart rate to gym equipment when paired to an iOS device, rendering the Pro 2 a better heart rate monitoring alternative for Android users than iPhone users.

The Powerbeats Pro 2 remain rated IPX4 for water resistance. While that’s not as robust as some other fitness-focused buds, it should be sufficient to survive sweat and outdoor runs in various conditions. The earbuds still offer easy-to-use physical buttons and a dedicated volume rocker, so it’s easy to control them in the middle of a workout.

If you’re an iPhone owner, the Powerbeats Pro 2 earbuds include Apple-only features like dynamic head tracking for spatial audio, auto device switching, Find My integration, and more. For Android users, Beats has an app that packs in a smaller subset of these functions.

The best earbuds for iPhone owners

$199

The Good

  • Much better noise cancellation
  • Improved sound quality and clarity
  • Unrivaled hearing health features

The Bad

  • Unchanged design
  • Sound is better but not top tier

Noise cancellation: Yes / Battery life: 6 hours (ANC on) / Water resistance: IPX4 / Bluetooth codecs: AAC, SBC / Multipoint: No / Works best with: iOS, Windows, macOS / Ear tips: Silicone (XS, S, M, L)

For those invested in Apple’s ecosystem, the second-gen AirPods Pro bring an appealing mix of top-notch noise cancellation and refined sound compared to the original pair. As always, they also include numerous features (spatial audio, audio sharing, automatic syncing across iCloud devices, etc.) that make them an ideal companion to the company’s other devices. They’re also the only AirPods that come with different sizes of ear tips for a customizable fit — including an extra small option.

The AirPods Pro have a compact case that supports wireless charging. Setting them up is as simple as holding the open case near your iPhone. The earbuds are lightweight and fit snugly in most ears. Their force sensor pinch controls are easy to get down, and with the second-gen model, Apple added swipe-based volume controls. The AirPods Pro have traditionally ranked among the best wireless earbuds when it comes to voice call quality, and the second-gen earbuds don’t disappoint. Their ANC is improved over the original model and is now right up there with Sony, and their transparency mode has gained the ability to quickly damper sudden, loud noises that might happen around you.

Where the AirPods Pro stand out is with their Apple-only features like head tracking for spatial audio, automatic device switching, extensive Find My support, and so on. The charging case now features a built-in speaker and a U1 chip for pinpoint location tracking, and the latest AirPods Pro have better sound and noise canceling capabilities than the original model. Plus, they retain their deep integration with Apple’s hardware ecosystem.

In the fall, Apple also rolled out an impressive set of hearing health features for the second-gen AirPods Pro. They’re now able to serve as clinical-grade hearing aids for people with mild to moderate hearing loss and protect your hearing in loud environments; you can even take a hearing test to assess your own level of hearing loss.

The best earbuds for Samsung Galaxy phone owners

$190

The Good

  • Terrific sound quality
  • Crisp, natural transparency / passthrough mode
  • Voice commands are simple and so useful
  • Good voice calls

The Bad

  • Uninspired design
  • Midtier noise cancellation performance
  • No true multipoint

Noise cancellation: Yes / Battery life: 6 hours (ANC on) / Water resistance: IP57 / Bluetooth codecs: Samsung seamless, AAC, SBC / Multipoint: No / Works best with: Android, Windows, macOS / Ear tips: Silicone (S, M, L)

Samsung’s Galaxy Buds 3 Pro ditch the company’s more discreet designs of the past for a stemmed style that’s similar to AirPods and any number of other wireless earbuds. Boring? Maybe, but thanks to that change, I’ve found them to be more comfortable and provide better stability than the Buds 2 Pro. The sound quality is even better than before — and it was already excellent. These are right up there with Sennheiser and Technics from an audio fidelity standpoint.

The Buds 3 Pro are also a standout performer when it comes to call quality. And my favorite thing about these earbuds are the hands-free voice commands that don’t require you to say any specific wake phrase beforehand. You can just say “volume up” and / or “next song,” and it happens.

But they’re not perfect: the Buds 3 Pro lack multipoint connectivity, so they can’t connect to two devices at the same time. Just like Apple, Samsung prefers to automatically hop between products within its own walled garden ecosystem. Some people might consider this a dealbreaker, but I’ve still enjoyed the earbuds plenty without it.

The best earbuds for Google Pixel phone owners

A hands-on photo of Google’s Pixel Buds Pro 2 earbuds.A hands-on photo of Google’s Pixel Buds Pro 2 earbuds.

$189

The Good

  • Smaller and lighter design is supremely comfortable
  • More powerful noise cancellation
  • Crystal-clear transparency mode
  • Very pleasant and detailed sound quality

The Bad

  • ANC can’t quite match Bose
  • Google still refuses to add higher-quality Bluetooth codecs, limiting overall fidelity
  • Gemini Live feels more feeble than futuristic

Noise cancellation: Yes / Battery life: 8 hours (ANC on) / Water resistance: IP54 / Bluetooth codecs: AAC, SBC / Multipoint: Yes / Works best with: Android, Windows, macOS / Ear tips: Silicone (XS, S, M, L)

With the Pixel Buds Pro 2, Google has addressed most of the downsides of the original pair. They’re far smaller and lighter than the chunky first-gen Pixel Buds Pro. And there’s a small nub on the buds to help lock them in place even during intensive activities like running or exercise.

Google’s active noise cancellation still isn’t on the same tier as Bose, but the transparency mode on the Buds Pro 2 is among the very best you’ll find. It offers a crisp, natural passthrough for the outside world when needed. Multipoint support is included, and Google’s latest earbuds eke out impressive battery life that surpasses most competitors.

A hands-on photo of Google’s Pixel Buds Pro 2 earbuds.

Got a Pixel phone? With the Pixel Buds Pro 2, you can have lengthy conversations with Google’s Gemini AI while your phone stays in your pocket. Features like head-tracking spatial audio and Clear Calling are also exclusive to those within the Pixel ecosystem. If that’s you, the Pixel Buds Pro 2 are a big step up from the previous buds in a much smaller package.

The best earbuds if you own both Apple and Android devices

$170

The Good

  • Better sound, ANC, and battery life than Studio Buds
  • Standout translucent case option
  • Improved voice call performance

The Bad

  • ANC and transparency fall short of second-gen AirPods Pro
  • Doesn’t offer all Apple ecosystem tricks
  • No wireless charging or in-ear detection

Noise cancellation: Yes / Battery life: 6 hours (ANC on) / Water resistance: IPX4 / Bluetooth codecs: AAC, SBC / Multipoint: No / Works best with: Android, iOS, Windows, macOS / Ear tips: Silicone (XS, S, M, L)

Beats’ Studio Buds Plus are an upgraded, better-performing revision of the Studio Buds released in 2021. This time, the company has made the noise cancellation more powerful while also improving the quality of the transparency mode and extending battery life. If you’re going for style points, it doesn’t get much cooler than the translucent color option. These earbuds are very tiny and rank up with the best in terms of overall comfort.

A photo of Beats’ translucent Studio Buds Plus earbuds.

What’s interesting about the Studio Buds Plus is that they use a proprietary chip that allows them to support native software features on both iOS and Android. Plenty of earbuds offer companion apps on each platform, but in the case of the Beats, they work with both Apple’s Find My and Google’s Find My Device. You also get simple one-tap pairing, no matter which operating system you’re using.

The drawback to this dual-ecosystem life is that Apple customers don’t get all the usual bells and whistles that come with AirPods or even the Beats Powerbeats Pro 2; you lose out on audio sharing, head tracking spatial audio, and other tricks. Wireless charging and an ear detection sensor (for auto-pause when a bud is removed) are also MIA, which stings a bit considering the price.

The best earbuds for sound quality

$231

The Good

  • Fantastic sound quality
  • Improved day-to-day reliability
  • Auracast-enabled

The Bad

  • Too pricey for some
  • Noise cancellation does the job, but isn’t anything special
  • Long-term durability remains to be seen

Noise cancellation: Yes / Battery life: 7.5 hours (ANC on) / Water resistance: IP54 / Bluetooth codecs: AptX Adaptive, AptX, AAC, SBC / Multipoint: Yes / Works best with: Android, iOS, Windows, macOS / Ear tips: Silicone (XS, S, M, L)

Sennheiser’s Momentum True Wireless earbuds have always sounded fantastic; that’s never been the issue. But previous models in the series have been tainted a bit by bugs, unsteady performance, and battery reliability problems. The fourth-gen pair finally gets that part right while continuing to offer tremendous, detailed sound quality that stands above nearly all competitors. They’re a joy to listen to. The active noise cancellation can’t compete with the likes of Apple, Sony, and Bose, but if you care more about lush, intricate sound, the MTW4 won’t disappoint in the slightest.

That copper finish is pretty nice.

These earbuds come with optional wing tips to help keep them securely locked in your ears. That could prove helpful for running or when hitting the gym. Sennheiser allows for plenty of EQ customization using its mobile app, and the Momentum True Wireless 4 support a range of Bluetooth codecs, including AAC, SBC, AptX, and AptX Adaptive. Sennheiser has also promised that they’re LE Audio and Auracast-ready for when those features become more widespread.

The best earbuds for voice calls on iPhone

A hands-on photo of Apple’s AirPods 4 wireless earbuds.A hands-on photo of Apple’s AirPods 4 wireless earbuds.

$119

The Good

  • Upgraded sound quality
  • Voice isolation can noticeably improve call clarity
  • Deep Apple ecosystem integration

The Bad

  • No wireless charging
  • No built-in speaker on the case
  • No proper multipoint

Noise cancellation: Optional / Battery life: 5 hours / Water resistance: IP54 / Bluetooth codecs: AAC, SBC / Multipoint: No / Works best with: iOS, Windows, macOS / Ear tips: None

Apple’s AirPods 4 come in two different versions, with a higher-priced option that includes active noise cancellation and wireless charging. But sound quality is identical on both sets, and equally as important in this case is that the same can be said of voice call clarity.

On the AirPods 4, there’s a new “voice isolation” feature — enabled by default — that uses machine learning both on the earbuds and your iPhone to eliminate distracting background noise on your end so that you come through clearly to whoever you’re speaking with.

A hands-on photo of Apple’s AirPods 4 wireless earbuds.

Photo by Chris Welch / The Verge

Overall call quality is excellent with the AirPods 4. And beyond that, compared to the third-gen model, you can expect upgraded audio quality (with richer bass), new ways of interacting with Siri through head movements, and yes… there’s a USB-C connector on the included charging case, as opposed to a Lightning port.

The AirPods still have a one-size-fits-most hard plastic form factor, so I recommend trying them before committing to a purchase. However, Apple says it used more than 50 million data points to further refine the contours and overall stability of its latest earbuds. So, if previous models worked well for you, these seem like a safe bet. The only question is whether you feel like spending a little more to gain ANC, a transparency mode, wireless charging, and a built-in speaker for Find My location tracking.

The best earbuds for voice calls on Android

  • Terrific sound quality
  • Crisp, natural transparency / passthrough mode
  • Voice commands are simple and so useful
  • Good voice calls

The Bad

Noise cancellation: Yes / Battery life: 6 hours (ANC on) / Water resistance: IP57 / Bluetooth codecs: Samsung seamless, AAC, SBC / Multipoint: No / Works best with: Android, Windows, macOS / Ear tips: Silicone (S, M, L)

Sony’s unconventional LinkBuds were our longtime pick for the clearest voice calls on Android, but we haven’t had the chance to review their successors. For now, the aforementioned Galaxy Buds 3 Pro are an easy-to-recommend choice. The built-in “voice pickup unit” detects the movement of your mouth to help isolate your voice from background noise and keep conversations clear.

The advantage of stemmed earbuds is that they position the mics closer to your mouth.

The Buds 3 Pro have proven dependable for me during video chats on Google Meet, and people have been able to hear me without issue, even when I’m answering a quick call on the street.

What every U.K. AI startup wants to know these days is, how can I get office space in King’s Cross?  

The area is so hot that a VC firm allegedly recently won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support” founders, “including helping them source office space when needed,” the firm told me when asked about the rumor, declining to confirm or deny any details. 

The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there. 

This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.  

Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.  

Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?  

“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.” 
 
Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.  

There are around 3,600 AI startups in London, which, together, have raised around $12.1 billion out of the $14.8 billion raised in the city since late July, according to Dealroom. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to the real estate firm Knight Frank. With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me. 
 
That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.  

Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.  

Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a $3.3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.  

“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me.  That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.  

Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.  

Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a .3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.  







“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

Top founders want to stay 

Simon Kohl, founder of Latent Labs, has offices in King’s Cross and San Francisco. The London office, at the moment, is growing faster, and he’s more bullish than ever on the ecosystem, he said. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said.  Look around and you are likely to see Wayve testing its autonomous cars. Founded in 2017 by co-founder Alex Kendall, the unicorn is one of London’s biggest success stories.  

“Ten years ago, building a frontier AI company from London felt like an unusual choice,” Kendall told me. “Now it feels like an obvious one.” Wayve moved into King’s Cross in 2018 looking for a space that could double as a garage — “a rare combination in Central London,” Kendall said. He has watched the ecosystem mature around him — and it’s now evident that a startup can stay in London, raise serious capital, hire world-class AI talent, and remain globally competitive, he said.  Down the street from Anthropic’s new 158,000-square-foot office is the AI agent builder Sierra and the AI video platform Synthesia. 

Laura Gonzalez Florez, Synthesia’s chief of staff and head of people, says the company moved into its glossy new office building a year ago to accommodate its growing team. They were drawn to the area for the same reason as everyone else: “It’s very close to the airport … very close to where a lot of investors are,” she said.

Around two-thirds of Synthesia’s engineers are remote, Gonzalez Florez said, letting the company tap into an affordable, international, and diverse talent pool and helping it scale faster. “From London, we can hire and work, without any problem, people from anywhere, from Slovenia to Portugal,” she said.  

Unsurprisingly, London’s AI boom is also causing a talent war.U.K. AI job postings have skyrocketed in the past few years, per data from PwC. When Anthropic announced it moved into town earlier this year, it listed, for example, a salary range of £260,000 to £630,000 for a machine learning research engineer when the average salary in London for the same role is around £102,000. Some founders in the U.K., like those in Silicon Valley, are being forced to raise more and bigger rounds to keep up. 

“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” Zain Ali, founder of the King’s Cross-based AI legal firm Centuro, told me. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”

What every U.K. AI startup wants to know these days is, how can I get office space in King’s Cross?  

The area is so hot that a VC firm allegedly recently won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support” founders, “including helping them source office space when needed,” the firm told me when asked about the rumor, declining to confirm or deny any details. 







The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there. 

This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.  

Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.  

Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?  

“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.”  Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.

The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there. 

This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.  

Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.  

Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?  

“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.”  Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.  


There are around 3,600 AI startups in London, which, together, have raised around .1 billion out of the .8 billion raised in the city since late July, according to Dealroom. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to the real estate firm Knight Frank. With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me.  That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.  

Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.  

Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a .3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.  







“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

Top founders want to stay 

Simon Kohl, founder of Latent Labs, has offices in King’s Cross and San Francisco. The London office, at the moment, is growing faster, and he’s more bullish than ever on the ecosystem, he said. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said.  Look around and you are likely to see Wayve testing its autonomous cars. Founded in 2017 by co-founder Alex Kendall, the unicorn is one of London’s biggest success stories.  

“Ten years ago, building a frontier AI company from London felt like an unusual choice,” Kendall told me. “Now it feels like an obvious one.” Wayve moved into King’s Cross in 2018 looking for a space that could double as a garage — “a rare combination in Central London,” Kendall said. He has watched the ecosystem mature around him — and it’s now evident that a startup can stay in London, raise serious capital, hire world-class AI talent, and remain globally competitive, he said.  Down the street from Anthropic’s new 158,000-square-foot office is the AI agent builder Sierra and the AI video platform Synthesia. 

Laura Gonzalez Florez, Synthesia’s chief of staff and head of people, says the company moved into its glossy new office building a year ago to accommodate its growing team. They were drawn to the area for the same reason as everyone else: “It’s very close to the airport … very close to where a lot of investors are,” she said.

Around two-thirds of Synthesia’s engineers are remote, Gonzalez Florez said, letting the company tap into an affordable, international, and diverse talent pool and helping it scale faster. “From London, we can hire and work, without any problem, people from anywhere, from Slovenia to Portugal,” she said.  

Unsurprisingly, London’s AI boom is also causing a talent war.U.K. AI job postings have skyrocketed in the past few years, per data from PwC. When Anthropic announced it moved into town earlier this year, it listed, for example, a salary range of £260,000 to £630,000 for a machine learning research engineer when the average salary in London for the same role is around £102,000. Some founders in the U.K., like those in Silicon Valley, are being forced to raise more and bigger rounds to keep up. 

“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” Zain Ali, founder of the King’s Cross-based AI legal firm Centuro, told me. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”

Why Remote Server Access Is a Common Attack Vector

Every cloud server exposes at least one remote access point – usually SSH on port 22 – and that port is scanned constantly by bots looking for weak credentials. Password-based login is the most common way a system can be attacked by brute force, and it is quite common with a standard setup that the system is left in a state where an admin/user of that system – “root user” – can log in directly by guessing the user ID and the password combination. Add in shared team credentials, forgotten firewall rules from old projects, and staging servers left publicly reachable, and it’s clear why misconfigured remote access – not zero-day exploits – is behind most cloud server compromises. The fix is simple, though you’ll need to do some setup yourself instead of trusting the default setting.

How to lock down SSH access in the right way

The best way to secure remote access is through a series of small improvements rather than one major overhaul. The following is a real working method:

  1. Switch to SSH key authentication, then turn off password login completely in the same location: sshd_config. Keys are far harder to brute-force than passwords.
  2. Disable root login over SSH and require a non-root user with sudo privileges instead; this is a security advantage that even without any change, one key compromising would limit the impact.
  3. Change the default SSH port away from 22 to cut down on automated scanning noise (not a security measure on its own, but it reduces log clutter).
  4. Restrict access by IP using your firewall or security group, allowing SSH only from known office or VPN IP ranges rather than the entire internet.
  5. Add a VPN as a connection layer for anyone accessing servers from outside a trusted network – a VPN like Planet VPN’s free VPN service can encrypt the connection between a remote worker’s laptop and the server before SSH traffic ever leaves their device, which matters especially on public wi-fi or shared networks.

Every step you take closes the doors that the attacker may open slightly, and when you combine everything, you would have a door to a series of locked gates.

Why Do I Need a Bastion Host?

When it comes to teams working with many servers, deploying a bastion host (jump box) may be a clean and effective way to solve the long-term problem. With this method, you only expose SSH to the bastion, and the other servers accept it only when it’s from the bastion’s internal IP. This centralizes logging and makes auditing access far simpler.

Using a virtual private network (VPN) and a bastion host together is perfectly fine – and many solutions use both: a safe way to access the private network via a VPN, followed by use of a bastion host to restrict which servers can be accessed. Some teams may decide to forgo the bastion because they don’t have the manpower to manage one, and so use a combination of a VPN and a set of firewall rules that still quite a bit lowers the exposure, but without the extra effort.

Mistakes Leading to Leaving Cloud Servers Open

The Mistakes That Cause Leaving Cloud Servers Open: Even the safest development teams may have slip-ups from time to time. One of the most frequent is leaving staged, or test servers with relaxed firewall rules equivalent to those of the production environment – hackers don’t concern themselves with which environment they first land on. Another frequent error is reusing the same SSH key on several servers and clients, causing one hacked laptop to compromise all servers that key has access to.

Another common human error is not removing or changing access when someone leaves the team, so stale credentials remain valid and accessible. At last, putting trust in the strategy of “security through obscurity” – meaning one thinks that setting up the unusual port or hiding the hostname from the public is actually sufficient security – creates a wrong impression of security. This is mostly true; in reality, modern-day attackers scan all ports anyway, and there is no way to hide from them.

System Administrators Guide to Secure Remote Access 

Prohibit SSH password logins totally and depend exclusively on key-based authentication

  • Surely no one wants to type in the password every time; because of this, use only key-based authentication 
  • Deter the user from logging in as root by default and instead use the sudo command to do root tasks
  • A firewall or security group rule can provide great help with IP address-based restrictions on SSH logins 
  • For access that comes from untrusted sources or external networks, use a secure tunnel like a vpn or bastion host
  • Periodically change SSH keys and inspect access lists
  • Maintain records of login attempts and detect brute-force attacks as quickly as possible

Frequently Asked Questions

What is the principal means by which cloud servers suffer break-ins through remote access?

By far the biggest reason why this can happen is unauthorized password-based SSH logins that have been cracked by brute force. The scenario is most likely to develop where the administrator allows root login via password and leaves the default port open.

Sufficient security measures for the server via SSH keys: Do you think it is safe to rely only on key authentication? 

It is true that SSH keys drastically decrease the danger of a successful brute-force attack. However, if there is only key authentication on the server, there are still risks – the server administrator can always enable root login or disable the IP-based login restrictions. So it is recommended to always have these three in the server configuration: disabled root login, restricted access to known IPs, and rotating the keys regularly as the main components of meaningful protection. 

Is it really necessary to set up a separate VPN network while I am able to connect via SSH keys? 

A VPN gives extra security by first encrypting your computer traffic before it reaches your network, where the SSH connection will be used. This is mostly important when working on untrusted networks – like public wi-fi – where there is a threat of a potential hacker in your local network looking at your data.

Bastion host vs VPN as methods of accessing the server? 

The bastion host works by funneling SSH sessions from many users through a single, carefully monitored server point while the rest of the network (and mostly the servers) remains protected from the internet. At the same time, a vpn will fully encrypt the communication between the user and the corporate network or servers. The combination is very common among larger security teams as a part of the defense-in-depth principle. 

How often should SSH keys be rotated? 

The ideal period to change your SSH keys depends on the security practices of your organization, but generally a good practice is to change SSH keys between 90 and 180 days, or in the case that the user who had access with the key leaves or is no longer able to be contacted, such as when a team member leaves.

Why is only changing the port number for SSH enough to secure that port?

Changing the port reduces automated scanning noise in your logs but isn’t a real security control on its own — port scanners check all ports, so it should never replace key-based auth and firewall rules.

Protection against unauthorized remote logins to your cloud server is a matter of SSH key-based authentication, a strict security policy on the firewall, two-factor authentication, and a secure communication channel – no individual component will give adequate protection by itself. The major risk point in breaches is not the server but the open door to remote login. To patch that vulnerability, you need a series of countermeasures, not a magical setting.

However, if there is only key authentication on the server, there are still risks – the server administrator can always enable root login or disable the IP-based login restrictions. So it is recommended to always have these three in the server configuration: disabled root login, restricted access to known IPs, and rotating the keys regularly as the main components of meaningful protection. 

Is it really necessary to set up a separate VPN network while I am able to connect via SSH keys? 

A VPN gives extra security by first encrypting your computer traffic before it reaches your network, where the SSH connection will be used. This is mostly important when working on untrusted networks – like public wi-fi – where there is a threat of a potential hacker in your local network looking at your data.

Bastion host vs VPN as methods of accessing the server? 

The bastion host works by funneling SSH sessions from many users through a single, carefully monitored server point while the rest of the network (and mostly the servers) remains protected from the internet. At the same time, a vpn will fully encrypt the communication between the user and the corporate network or servers. The combination is very common among larger security teams as a part of the defense-in-depth principle. 

How often should SSH keys be rotated? 

The ideal period to change your SSH keys depends on the security practices of your organization, but generally a good practice is to change SSH keys between 90 and 180 days, or in the case that the user who had access with the key leaves or is no longer able to be contacted, such as when a team member leaves.

Why is only changing the port number for SSH enough to secure that port?

Changing the port reduces automated scanning noise in your logs but isn’t a real security control on its own — port scanners check all ports, so it should never replace key-based auth and firewall rules.
