The answers to today's Connections, game #518, are…

• YELLOW: BARREL-SHAPED CONTAINER CASK, CYLINDER, DRUM, TANK
• GREEN: GUIDE PILOT, SHEPHERD, STEER, USHER
• BLUE: N.F.L. TEAM MEMBER COWBOY, JET, RAM, RAVEN
• PURPLE: THINGS THAT SWING GOLFER, PENDULUM, SALOON DOORS, SWING

• My rating: Easy
• My score: Perfect

I can't help thinking it's a bit of a cop out for the NYT to include the word SWING in a group where the answer is, um, SWING. I mean come on! This was the purple group, too, so supposedly the hardest of the four.

Admittedly, the others were easier still. Blue – the second toughest – was N.F.L. TEAM MEMBER, and even a UK soccer/cricket fan such as myself could spot that COWBOY, JET, RAM and RAVEN were the answers. Green, meanwhile, was simply four things that were all BARREL-SHAPED CONTAINERs: CASK, CYLINDER, DRUM and TANK. My finger hovered over the submit button with that one, because I thought it couldn't possibly be as easy as that. But it was, and for once I completed this game with no trauma.

What is NYT Connections?

NYT Connections is one of several increasingly popular word games made by the New York Times. It challenges you to find groups of four items that share something in common, and each group has a different difficulty level: green is easy, yellow a little harder, blue often quite tough and purple usually very difficult.

On the plus side, you don't technically need to solve the final one, as you'll be able to answer that one by a process of elimination. What's more, you can make up to four mistakes, which gives you a little bit of breathing room.

It's a little more involved than something like Wordle, however, and there are plenty of opportunities for the game to trip you up with tricks. For instance, watch out for homophones and other word games that could disguise the answers.

It's playable for free via the NYT Games site on desktop or mobile.

Strands is the NYT's latest word game after the likes of Wordle, Spelling Bee and Connections – and it's great fun. It can be difficult, though, so read on for my Strands hints.

The answers to today's Strands, game #252, are…

• JUMP
• CIVIL
• STRONG
• BUSINESS
• BIRTHDAY
• LEISURE
• SPANGRAM: WELLSUITED

• My rating: Moderate
• My score: 2 hints

I find myself disagreeing with the NYT's choice of theme hint fairly often. This is possibly unfair, because as I know from experience it can be a very tricky thing to think of a clue that is helpful without giving the game away. But even bearing that in mind, the choice of 'Nice fit' here seems slightly misleading. After all, 'nice fit' works perfectly well for the spangram, WELLSUITED, and for some of today's answers – for instance LEISURE and JUMP. But it doesn't work for CIVIL or BIRTHDAY at all; these are types of suit, yes, but they aren't a 'nice fit' in any way. STRONG can be – if something is your strong suit, it is a good fit for you. But CIVIL in particular… no, it needed a different clue here.

That set me on the wrong path here, and I needed two hints to establish that yes, all of the answers were types of suit. Once I knew that it was pretty easy to find the others. And maybe that's why it's best that the hint did throw me off the scent – because without that I'd have probably had yet another perfect game, and that gets boring after a while…

Anker Nebula Mars 3: two-minute review

If you’ve been looking for a projector you can wow your friends with, the Anker Nebula Mars 3 might be the one. Despite looking like a monster-sized flashlight, the Nebula Mars 3 is a portable projector designed for use both on the go and at home. To that end, it has a built-in battery that lets it operate at full brightness for upwards of two hours, plus the Android TV smart TV platform for streaming and fairly beefy speakers, though they regrettably play in mono. It’s well constructed, and works effectively, letting you set it down and get up and running quickly.

Where the Anker Nebula Mars 3 really impresses is its brightness, which knocks it out of the park compared to most other battery powered examples of the best portable projectors. It’s not enough to challenge daylight, but it’ll sizzle at night. At just over $1,000, it has competition, and you can also find 4K models around that price, though few have the portability on offer here. You can also get better color from triple-laser options like the LG CineBeam Q or JMGO N1S Pro, albeit at a lower brightness for the LG and no on-the-go use for the JMGO.

If you’re planning to do most of your viewing at home, it’s probably worth getting a projector that skips the battery and puts more effort into picture quality. But if you want a robust all-in-one theater you can tote anywhere, the Anker Nebula Mars 3 is a commendable option.

Anker Nebula Mars 3 review: price and release date

• Release date: July 2023
• Price: $1,099 (around £850 / AU$1,645)

The Anker Nebula Mars 3 launched in 2023 and is now readily available in the US for $1,099. It can occasionally be found for less, however, and was $50 off at the time of writing.

The Nebula Mars 3 features a sliding lens door and is IPX3 water resistant (Image credit: Future) Anker Nebula Mars 3 review: Specs

The Nebula Mars 3's rear-panel ports cover and flashlight feature (Image credit: Future) Anker Nebula Mars 3 review: design and features

• Built for portability and durability
• Convenient on-device controls
• Built-in speakers and Android TV operating system

The Anker Nebula Mars 3 follows Anker’s Nebula series design language, bearing considerable resemblance to the Nebula Cosmos 4K SE projector. That said, there are considerable differences that make the Nebula Mars 3 stand out.

This model is built for more of a rough-and-tumble, on-the-go lifestyle. It features a hardened case that can withstand half-meter drops and has IPX3 water resistance. The front has a sliding lens cover and the rear includes a rubber cover over the ports. A sizable, hard handle stretches across the top of the projector, extending from the front to the back. While it includes a remote control, the handle also has built-in controls for volume and navigation of the projector’s onboard operating system. Neither of these control options is quite perfect though, as the remote is fairly limited in what you can access with a single press and the built-in buttons lack many of the typical controls for navigating the projector’s Android TV smart TV interface.

A key part of the portable nature of the Anker Nebula Mars 3 is its ability to operate outdoors. To that end, the projector integrates a beefy battery geared up to run for anywhere from 2 hours at full blast to 5 hours in a dimmer Eco mode. To help you keep track of power, the handle has a ring of lights that display battery level. The projector can also double as a Bluetooth speaker or a flashlight. A three-speaker built-in audio system resides near the front. It can pump out a good deal of sound, though only in mono and the dynamics are fairly weak. Meanwhile, an LED light bar sits along the rear, stretching out above a large exhaust vent and below the port cover.

Since the Anker Nebula Mars 3 isn’t designed to have a permanent home, it has a small, adjustable stand underneath to help angle it up at projection surfaces wherever it’s ultimately set up. It also features a quick and effective system for automatically adjusting image focus, keystone, and framing.

The projector’s Android TV 11 smart TV system is a little dated, but still effective as a streaming platform. Like many other projectors, though, it doesn’t get the Play Store version of Netflix, instead relying on a sideloaded version that offers a generally sub-par experience. If you’re off the grid and don’t have internet, the projector has a USB-A port and supports local media playback.

To upgrade the audio experience, you can wire it up to external powered speakers using the AUX port or wirelessly pair it to a Bluetooth speaker.

• Design and features score: 4/5

The Android TV platform is used by the Nebula Mars 3 for streaming (Image credit: Future) Anker Nebula Mars 3 review: picture quality

• Good, but not exceptional picture
• Decent color and detail
• Enough battery power for a 2-hour-plus movie

The Anker Nebula Mars 3 features an LED DLP projection system rated for 1,000 lumens and 1080p resolution. That’s about what should be expected from a projector sitting at around $1,000.

Anker’s battery powered portable has a good-looking picture, but not an exceptional one. It isn’t the type of projector you’ll want if you’re viewing in a bright room, since its 1,000 lumens just aren’t enough to handle much ambient light. You might get by if you’re watching bright cartoons, but you really should be viewing with it in a dark space, and that extends to the outdoors as well. Controlling ambient lighting outdoors is even more difficult than indoors, and if you’re expecting a good viewing experience with lots of urban lighting present, you’ll be disappointed. That said, if you’re in a more rural area without much light pollution, the Anker Nebula Mars 3 should provide ample brightness after sunset.

The color you’ll get from the Anker Nebula Mars 3 is decent, but no match for triple-laser portable projectors like the LG CineBeam Q. It doesn’t feel utterly lacking or poorly managed, and a show like Ru Paul’s Drag Race still had plenty of visual spark when I viewed it. Colors have modest vibrance, but just don’t get the same level of pop I’ve seen from HDR-capable projectors reaching toward 100% coverage of the UHDA-P3 color space. The same is true of its resolution. At a projected image size of around 65 inches, the projector's 1080p image looks reasonably crisp, but go far above that and you will seeing more softness unless you sit further back. A larger image will also show an artifact of the projector’s DLP chip, which shows up as noticeable dithering (an effect like writhing small dots) when displaying dark colors over a large portion of the screen.

The projector has a motion smoothing setting buried slightly in the settings menu under the label MEMC that is set to on by default. While it can smooth out certain motions, it creates all sorts of distracting effects, especially in action sequences like those in Gladiator. It’s worth turning off, which results in more natural motion.

Many of the image trade-offs are a result of Anker needing to squeeze a battery in for the $1,099 price. And the battery makes it worth it. At full brightness, the Nebula Mars 3 was able to run for the entirety of a two-hour movie at 50% volume with a little over 20% charge to spare, which let it go for nearly 30 minutes longer. Annoyingly, if you’re nearing the end of your movie or show and the battery power starts to get low, your experience will be thoroughly interrupted by several low-battery warnings in a window that occupies a large portion of the display.

• Picture quality score: 3/5

A remote control is included, and there are also controls located on the projector's handle (Image credit: Future) Anker Nebula Mars 3 review: value

• Great for portable use
• Brighter than other compact portables
• Better options for picture quality, but not portability

The Anker Nebula Mars 3 is an interesting package. It’s not a great home theater projector for the money, as there are far more appealing options available in the same ballpark. But it’s an overall decent projector and a powerful portable one. The Nebula Mars 3 is quick to set up, and can run for hours at a time. It’s a knockout next to something like the Samsung The Freestyle 2nd Gen, which has a portable setup with an optional battery pack but isn’t nearly as bright.

A competent projector you can bring anywhere and easily get up and running is something special, and the Anker Nebula Mars 3 nails the concept. It’s built to withstand surprises and has clever elements (like the lens cover and waterproofing) that let you easily grab it and go without worrying about a protective case.

• Value score: 4/5

The carrying handle control buttons (Image credit: Future) Should I buy the Anker Nebula Mars 3?

(Image credit: Future) Buy it if...

You want an easy on-the-go projector: The key feature of the Anker Nebula Mars 3 is its ability to operate just about anywhere. Its handle is ready for travel and its battery lets it run for upwards of 2 hours at full brightness.

You’re rough with your gadgets: The Nebula Mars 3 isn’t indestructible, but it‘s a good deal more durable than other projectors. With hardware that can withstand 0.5-meter drops and rain, you can be a little more rough with this device.

You’re outdoorsy: The Nebula Mars 3 isn’t just a projector. It has a lamp that can come in handy at a campsite, and if you're not watching something, the built-in speaker can serve as a Bluetooth speaker. You can even use it as a power source for charging other electronics.

Don’t buy it if… 

You’re never taking it outdoors: The Nebula Mars 3 is decent, but not exceptional when it comes to home theater viewing. You can easily get a cheaper projector with equivalent picture quality.

You want a really big, bright picture: The Nebula Mars 3’s 1080p resolution and 1,000 lumens brightness don’t really cut it for big-screen viewing unless you’re not picky about picture detail and have a dark viewing space.

You want great built-in sound: The Nebula Mars 3 has some hard limits when it comes to audio. Its built-in speakers are regrettably mono and there’s no optical digital or eARC ports to tap into higher-quality sound devices.

LG CineBeam Q
The CineBeam Q is absolutely tiny next to the Anker Nebula Mars 3, and it’s nowhere near as bright, but benefits from a far more colorful projection system, 4K visuals, and a much better streaming platform. For viewing in the dark, it can work wonders.

Samsung The Freestyle 2nd Gen
Samsung’s The Freestyle 2nd Gen is a smaller, somewhat cheaper alternative, though that depends on any discounts. It has greater portability size-wise, but requires an external battery pack. Next to the Anker Nebula Mars 3, it’s kind of a toy projector.

(Image credit: Future) How I tested the Anker Nebula Mars 3

• Tested at home in multiple, real-world viewing conditions
• Presented the display with a variety of media and formats
• I have tested numerous projectors and displays over the last half-decade

I tested the Anker Nebula Mars 3 at home, in real-world conditions. This saw it faced with ambient light coming in from numerous windows, in-room lighting, as well as ambient noise that both the projector and speaker systems had to overcome. The projector was tested both against a bare, white wall and an Akia Screens CineWhite screen. It was presented with streamed content, both HDR and non-HDR.

My testing evaluates the projector’s performance with respect to its price and competition from other models I and colleagues at TechRadar have tested.

I have been testing projectors since 2021 and displays for even longer.

First reviewed: November, 2024

• New HPE fanless cooler cuts server blade power consumption by 37%
• The system uses direct liquid cooling, perfect for AI technologies
• The architecture is designed to be scalable dependent on business needs

Hewlett-Packard Enterprise (HPE) recently hosted its AI Day 2024 event, introducing the industry’s first 100% fanless direct liquid cooling architecture.

As artificial intelligence (AI) technologies continue to evolve, power consumption in next-generation accelerators has increased, surpassing the capabilities of traditional air-cooling methods.

Organizations running large-scale AI workloads are now searching for more efficient solutions to manage their infrastructure’s energy demands, and hPE has pioneered direct liquid cooling technology, which has become one of the most effective methods for cooling high-performance AI systems. This approach has allowed HPE to deliver seven of the top 10 most energy-efficient supercomputers on the Green500 list.

100% fanless direct liquid cooling addresses cooling challenges in AI systems

The new cooling system is designed to improve efficiency in several key areas, with HPE saying the fanless architecture reduces cooling power consumption by 90% compared to traditional air-cooling systems and offers significant environmental and financial advantages.

The system is built on four core elements. First, the system uses a comprehensive cooling design featuring an 8-element system that cools the GPU, CPU, server blade, local storage, network fabric, rack, cluster, and coolant distribution unit (CDU).

The second element is that the fanless cooler also offers high-density performance that supports compact configurations backed by rigorous testing, monitoring software, and on-site services to ensure smooth deployment.

Thirdly, for those with a mind for the environment, the new system uses an integrated network fabric that enables large-scale connectivity with reduced costs and power consumption for a more sustainable architecture. Lastly, the architecture runs on an open system design that offers flexibility by supporting various accelerators, allowing organizations to select solutions that best suit their needs.

The fanless architecture reduces cooling power consumption by 37% per server blade compared to hybrid liquid-cooled systems, not only lowering utility costs but also reducing carbon emissions and eliminating data center fan noise. Furthermore, the design allows for higher server cabinet density, helping organizations cut floor space requirements in half.

"As organizations embrace the possibilities created by generative AI, they also must advance sustainability goals, combat escalating power requirements, and lower operational costs,” noted Antonio Neri, President and CEO of HPE.

“The architecture we unveiled today uses only liquid cooling, delivering greater energy and cost-efficiency advantages than the alternative solutions on the market. In fact, this direct liquid cooling architecture yields 90% reduction in cooling power consumption as compared to traditional air-cooled systems."

• Power-over-Skin developed by researchers at Future Interfaces Group
• Technique transmits power to wearables using the human body
• Paves the way for battery-free devices powered through skin contact

Self-winding watches have existed for a century, but manufacturers are still searching for ways to make modern wearables battery-free. A new research paper from Carnegie Mellon University could have the answer: scientists have developed a technique to power the next generation of wearable tech via skin contact.

Researchers at Future Interfaces Group have found a way to deliver power to wearable devices through the human body. The method is called Power-over-Skin, and it could be the gateway to a future where the best smartwatches no longer need a built-in battery.

In simple terms, the method sends power from a single battery-powered transmitter worn on the body to a range of battery-free devices attached to the skin. Research has found that the human body effectively conducts 40 MHz RF energy, which is what Power-over-Skin relies on to distribute power through the skin.

Researchers Andy Kong, Daehwa Kim, and Chris Harrison found they could deliver power from a single transmitter across the whole body. They also found that the amount of power they could deliver depended on the proximity of the transmitter and receivers. For example, having a transmitter on the forearm with a receiver on the wrist netted higher microwatts.

In their tests, the researchers were able to power an LED earring, a calculator, and a Bluetooth ring with a joystick control. They also experimented with building transmitters into existing objects, including a smartphone, a VR headset, and a shoe. Because the skin connection is capacitive, it can also work through clothing, such as having a transmitter in your pocket.

Skin in the game

The benefits of Power-over-Skin are several. By eliminating built-in batteries, wearable devices could be made much smaller and lighter, unlocking the potential for various versatile applications. One mentioned in the research paper is a slimline medical patch that monitors health metrics. Because there’s no battery to replace, it could, in theory, stay on a patient indefinitely.

Another net gain from Power-over-Skin is that sharing power from a single transmitter source instead of fitting individual wearables with their own batteries reduces the resources required from an environmental perspective.

As the technology develops, refinements should lead to greater efficiency in power delivery. While it’s unlikely that Power-over-Skin will be able to provide enough energy to run high-power devices, it seems reasonable to assume the technology will be leveraged on the likes of smartwatches and fitness trackers in the near future.

In conducting their tests, the researchers proved that Power-over-Skin can run microprocessors, digital displays, and wireless communication modules, albeit ones optimized for the technology. With the right placement of the transmitter and receiver and improvements in component efficiency, there are many possibilities for future wearables.

One concern will be whether using the body as a conduit for RF energy has any negative side effects on a wearer’s health. A factor addressed in the paper is the need to avoid hotspots, where RF energy passes through a small contact area.

According to the research, no participants encountered discomfort or pain during testing. Assuming that there are no complications from long-term exposure, Power-over-Skin could mark a massive shift in how wearables are designed and powered.

• Samsung to release 400-layer NAND chip for AI data centers
• New BV NAND tech boosts density and minimizes heat buildup
• Plans for 1,000-layer NAND by 2030 to expand capacity

Samsung is working to launch a record-breaking 400-layer vertical NAND flash chip by 2026, reports have claimed.

A report by the Korea Economic Daily says Samsung’s Device Solutions (DS) division aims to advance the NAND flash market with its cutting-edge V10 NAND, designed to meet surging demand in AI data centers.

The company’s memory roadmap, as outlined in the report, shows plans for an advanced 10th-generation NAND that will utilize bonding technology to separately build memory cells and the peripheral circuitry on different wafers, later fusing them into a single chip. Known as bonding vertical NANDFlash (BV NAND), this new approach minimizes heat buildup and maximizes both capacity and performance, creating what Samsung has described as a “dream NAND for AI.”

1,000 layers by 2030

The BV NAND design, boasting a 1.6x increase in bit density per unit area, supports ultra-high-capacity solid-state drives (SSDs) ideal for AI applications.

Samsung’s current 286-layer V9 NAND chips marked a significant milestone, but the 400-layer V10 is expected to redefine capacity limits, potentially breaking the 200TB storage threshold for ultra-large AI hyperscaler SSDs, while improving energy efficiency.

For future releases, world’s largest memory chipmaker plans to introduce 11th-generation V11 NAND in 2027 with a 50% faster data transfer speed, further optimizing performance for high-demand data storage needs.

Samsung’s ambitious NAND roadmap extends even further, with plans for chips exceeding 1,000 layers by 2030, KED reports. This advancement aims to keep Samsung at the forefront of the high-capacity NAND market, where demand is spurred by AI applications that require expansive storage solutions to process vast volumes of data.

In the DRAM sector, Samsung aims to release sixth-generation 1c DRAM and seventh-generation 1d DRAM by the end of 2024, targeting use in high-performance AI chips. According to the Korea Economic Daily report, the company also has plans for sub-10 nm 0a DRAM by 2027, using a vertical channel transistor structure for greater stability and efficiency.

Sonos Arc Ultra review: Two minute review

The Sonos Arc Ultra is the new flagship in Sonos’ soundbar line-up, and it takes everything that was good about the original Arc and cranks it up to the next level. Better Dolby Atmos effects, better bass, better speech clarity, better connectivity.

The Sonos Arc Ultra is a huge step up for music quality over the original Sonos Arc, and while it’s less of a jump up from the original with movies, it’s still a clear and obvious improvement, and ranks among the best soundbars.

Is it worth upgrading from the original Sonos Arc? I think that’ll depend on how much of a cinephile you are; I really appreciated the improved sound balance and the clearer speech, and the obvious improvement to Dolby Atmos effects positioning, and found it hard to go back – but the original Sonos Arc is no slouch, and more casual viewers may find the difference to feel less essential.

The Sonos Arc Ultra keeps the original’s biggest flaw, which is not having any HDMI passthrough port in an era when HDMI ports are becoming a bit of a premium, and effectively all its key rivals offer this. The lack of DTS is also a shame, but won’t be a big problem for most people. I still thoroughly recommend the Sonos Arc Ultra, but it just may not be the best fit for your setup because of its HDMI limitation.

For those wondering about Sonos’ app, I had no problems setting it up, playing with different configurations, and changing settings.

I’m reviewing the Sonos Arc Ultra as a single soundbar here, though I have tested it with the Sub 4 and rear speakers, and I’ll talk about that experience too.

I think the Sonos Arc Ultra gives you the best cinematic experience you can get from a single-unit soundbar for under $1000 / £1000. However, in the UK, you can get the Samsung HW-Q990D for around the same price during sales events, and if you’re happy having a four-box surround system, you’ll get a far more immersive experience. And Sony’s Bravia Theater Bar 9 is a key competitor around the world – it's a single-box soundbar like the Arc Ultra, but it offers the missing HDMI port, and with 4K 120Hz support, no less. It officially costs a lot more than the Sonos Arc Ultra, but sales season discounts bring it down to around the same price. It’s even bigger than the Arc Ultra, though.

(Image credit: Future) Sonos Arc Ultra review: Price & release date

• Released on October 29, 2024
• Priced at $999 / £999 / AU$1,799

The Sonos Arc Ultra is priced pretty well at $999 / £999 / AU$1,799, considering that other flagship one-box soundbars can be far higher, such as the $2,399 / £1,990 / AU$3,999 Devialet Dione, or the $1,399 / £1,399 / AU$1,795 of the Sony Bravia Theater Bar 9.

Obviously, it's not cheap, and you can find the Samsung HW-Q800D for significantly less, but that's not a one-box soundbar, and building high-quality sound into a single unit that isn't huge (which the Devialet Dione especially is) is hard. For a premium soundbar, the Arc Ultra is competitive.

Much like the original Sonos Arc, this is a Dolby Atmos soundbar with HDMI eARC connectivity, Sonos multi-room wireless support, and optional voice control from Alexa or Sonos’ own more limited voice assistant.

The biggest new feature is the Sound Motion driver, which delivers big bass performance from a small speaker, and a generally improved speaker setup that now promises 9.1.4 channels of sound, compared to 5.0.2 from the original Sonos Arc.

There’s also Bluetooth connectivity in the Arc Ultra, which is a first for a Sonos soundbar, but is now standard on the best Sonos speakers at last, including the recent Sonos Era 100 and Sonos Era 300.

Naturally, the Sonos Arc Ultra works with Sonos’ Sub options (including the new Sub 4 as well as older models) and you can connect it to rear speakers for a real surround sound setup. The Arc Ultra is the first Sonos soundbar that doesn’t work with the Sonos Play:1 or Play:5 speakers – but it still works with Sonos One, Sonos Five, the Era models, or with two wired speakers connected to a Sonos Amp.

Sonos’ TruePlay room-tuning tech is here, and it’s finally available on Android in a new ‘quick’ version, which is also available on iOS. This new version will probably be preferable for a lot of people because it’s much easier. It uses the Arc Ultra’s own mic array to test your room using a series of pet-alarming tones, to adjust the system’s sound for better precision and Dolby Atmos surround effects. On iOS, it still asked me to hold my phone where I sit for a set of measurements there first, which is what the full TruePlay system does – but then I didn’t have to walk around the room waving my phone up and down.

The biggest flaw in the Sonos Arc is the lack of any HDMI passthrough ports. Most premium soundbars have more than one HDMI port – one to connect to your TV, and then at least one other that passes video through to your TV, so that you don’t lose the use of one of your HDMI ports for connecting consoles or other video boxes. This is doubly annoying in the majority of TV models available today, which only have two HDMI 2.1 ports for 4K 120Hz support at most, and the HDMI eARC is usually one of those ports, so you’re losing one of the most important ports. (Many LG and Samsung TVs have four HDMI 2.1 ports, so this is less of a problem, and in 2025 far more TVs will have four HDMI 2.1 ports thanks to a new chip from MediaTek – but that doesn’t help TVs today.)

Even ignoring the type of ports, four video devices is not an uncommon amount for people to want to connect to a TV here in 2024, and yet if you have the Sonos Arc Ultra, you can only connect three.

It’s so frustrating, given that it was a complaint I had about the original Sonos Arc when that launched in 2020. I’ve spoken to Sonos about the topic, and the company’s stance has been that HDMI passthrough adds complexity and it wants its soundbars to be as simple as possible. But that only holds true if someone doesn’t then have to deal with the headache of what a good solution is if they want to connect more devices than they have ports free, once the Arc Ultra is connected. I think Sonos has simply off-loaded the complexity to users. With an HDMI passthrough port, I’d have been seriously looking at giving the Arc Ultra a five-star rating overall.

The other notable issue is a lack of DTS decoding. This is not a big problem if your TV or playback device will decode DTS-HD to LPCM, as many will. I had a great time playing DTS-HD Blu-rays while testing the Sonos Arc, and getting the big, powerful, high-quality sound I was expecting. The lack of DTS:X is the more annoying part for purists, especially with it now used on Disney Plus for some movies, but it really isn’t a dealbreaker for the vast majority of people.

The Sonos Arc Ultra works with the audio-swap feature of the Sonos Ace headphones, so you can watch anything that plays on your TV with great spatial audio on the headphones to avoid disturbing others in the house – our Sonos Ace review has more on how well that works, but it’s not affected by the Sonos Arc Ultra's performance, so I won’t go into it here.

• Features score: 4 / 5

I tested the Arc Ultra on its own, and with Sonos' complete Dolby Atmos setup. (Image credit: Future) Sonos Arc Ultra review: Performance

• Excellent dynamic range
• Very strong Dolby Atmos effect
• Very clear speech and detail

In my opinion, the Sonos Arc Ultra is the best-sounding single-box soundbar you can get for under $1,000 / £1,000. It delivers fulsome balance and exciting sound with clear speech, and superb height and width. The Devialet Dione maybe does this all better as a single-unit soundbar, but at around twice the price and twice the size, it’s a harder sell in several ways.

Dolby Atmos surround effects don’t seem like they’re coming from behind you, inevitably, but they do feel like they reach you when there are movement effects in particular. Height channels have motion and precision, despite being part virtual – Sonos claims four channels of overhead sound, but there are only two drivers, with the width drivers combining with the height drivers for a sense of four channels, and it works well.

Sound is layered very impressively in Dolby Atmos, with a sense of 3D positioning across the whole space in front of you.

Everything is an improvement over the original Sonos Arc. It’s not quite night and day, but it’s a clear step up anyway. That especially goes for speech clarity and Dolby Atmos effects in movies, with everything feeling just more expansive and more in the room than from the older soundbar.

I tried Sonos’ new and upgraded speech enhancement tools for the Arc Ultra, and they’re very effective, but they affect the sound balance (as do all such tools), and I found that I really didn’t need them anyway on the Arc Ultra. It’s a bit unoriginal to say that the speech in Christopher Nolan movies is hard to hear, but I tested the old and new Arc with them, and there was a big jump in legibility on the Arc Ultra that meant they really weren’t hard to follow any more (generally).

Surprisingly, the new bass driver didn’t create that big an effect compared to the original Sonos Arc in movies that already ramp up the bass, but it does help to make the sound feel fuller in general. It makes the bass that the Arc Ultra can generate better connected through to the mid-range, so the overall balance in low-end-heavy scenes is stronger – and just excellent overall. There’s a good dispersal of the bass so that it doesn’t feel too directional, and the impact is really pleasing for such a relatively compact soundbar.

The Sound Motion bass speaker did really jump out during music though. This actually was a night and day difference from the original Arc, with a massive improvement across the whole frequency range. For music, the original Arc sounded unclear and subdued compared to the Arc Ultra at the same volume. Having said that, I would still put the Arc Ultra essentially on par for music quality with the Sonos Era 300, which is half the price. It’s easier to fill out that sound when you can be thick and tall, unlike a soundbar.

Running TruePlay tuning helps the Dolby Atmos and finer details to come through more clearly, so I absolutely recommend it. There wasn’t a clear difference between the quick version and the full version in my setup, so as I mentioned above, the quick version should be all that most people need to bother with.

To repeat myself from the start of this section, I think the Arc Ultra delivers the best-value cinematic experience from a single-box soundbar. It’s the best combination of a demure design, effective sound reproduction and 3D effects, and a reasonable price given what it can do. More expensive soundbars may do better, but the audio package here is excellent.

I’m reviewing it as a single unit for all the scores here, but I also tested it with a Sub 4 and Era 300 speakers in Sonos’ full-power ultimate system. I also tested it with a Sub 4 only, and then slotted it and the Sub 4 into my existing setup using my Sonos One rear speakers.

Make no mistake – despite the Sound Motion tech being very impressive for bass, the Sub 4 adds a whole new dimension of bass you can feel, in frequencies the soundbar alone simply can’t touch. You will literally get more from your movies with a big sub, though obviously for a premium of $799 / £799.

In the full elite surround mode, with Era 300 units behind as well, you can really feel the overall power of the system. Even with one sub (you can connect a second to more fully spread the bass around) you can feel the power of the low frequencies everywhere, with excellent fullness through to the mid-range, and a clear separation of higher frequencies from that mix. It’s a really well-connected whole system, and testing against the Samsung HW-Q990C, I say you get a more satisfying overall sound profile from the Sonos setup. However, not by that much, considering you’ll pay a lot more for the Sonos system – it kind of proves why Samsung’s top-end soundbars are five-star products among the best Dolby Atmos soundbars. Still, for those with the ear, I think the Sonos system’s sound is superior.

Even with my Sonos Ones as rear speakers, I felt like I was getting a different sound profile from the rears (post TruePlay) than with my Sonos Arc and Sub Mini that I usually have. They felt punchier and with a little more bass added to them, perhaps to match the broader sound profile the bar is capable of compared to the original Arc. I feel that swapping the Arc for the Arc Ultra in my setup would be an upgrade, albeit one that I would enjoy as someone who’s obsessive over sound and setups – perhaps someone more casual about home theater wouldn’t find it to be as good value.

• Performance score: 5 / 5

The concave volume control matches other recent Sonos releases. (Image credit: Future) Sonos Arc Ultra review: Design

• Very well made and subtle
• Some key buttons hidden at the back
• Shorter but wider than original Arc

The Sonos Arc Ultra is 18% smaller by volume than the original Sonos Arc, according to Sonos, and this manifests in it being less tall (which is very welcome) and less deep (also welcome for those with chunky TV stands, though it’s still somewhat deep because it has a chunky bar across the back). However, it’s actually wider than the Sonos Arc. It’s still good for TVs of 55 inches and up, though, and the shorter height can make a real difference with some TVs.

It comes in black and white, and the overall look is very simple and classy. A hard, curved grille covers the entire thing, and it’s good at just disappearing into the room, which is what most people will want. The new design seems to pick up fingerprints worse than the old one, so be warned if you’re fastidious and have handsy kids.

The button for activating Bluetooth pairing mode is on the back, which is inconvenient for a soundbar, especially if it’s wall-mounted. You can pair from the Sonos app instead, but it would be better still if the Bluetooth button was on top, for maximum flexibility – especially since the button layout here was redesigned anyway, including moving volume over to the right, for whatever reason. In the middle, you still have buttons to play/pause, and skip tracks.

The switch to kill the voice control mics is also on the back, and is turned on by default, so the privacy conscious should remember to hit this before getting it situated. Also on the back is an Ethernet port, and then the power and HDMI ports are on the sides of the bit port cutaway on the rear – just like the original Arc.

The Arc Ultra is wall-mountable and works on the same mounts as the original Arc, which is nice for upgraders – though some of the mount may be visible, due to the change in size.

• Design score: 4 / 5

• Use Sonos app to get started
• TruePlay is now easier, and very useful
• Once connected to the TV, very little effort needed

If you have read or watched anything about recent Sonos releases, you will have seen strong opinions about the new Sonos app. We can’t post a video covering Sonos without a cascade of comments saying no one should ever buy Sonos again because of the state of the software. At launch, earlier in 2024, the app was missing a lot of features, and a lot of people had problems accessing or making changes to their systems.

At the time of writing this review, Sonos says that it has added 90% of the missing features back in, and is still committed to updates every two weeks to address bugs and performance while adding the remainder of the features.

I had no problems at all setting up the Arc Ultra at home through the app, making the settings adjustments I needed, and then adding/breaking multiple different surround setups while I tested different configurations of Sonos setups.

I did have trouble setting the surround system up in our office testing rooms, where the connection between the components would drop regularly – but this is pretty common on our office Wi-Fi outside of Sonos. I’ve had a problem getting Samsung’s soundbars to connect to register on the SmartThings app, and it can be difficult with smart home tech, so I don’t blame Sonos for this – but it’s only fair to note it if I’m going to dig into the experience. At home, on my normal mesh router setup, I had no problems at all.

The usability of Sonos’ soundbars continues to be a slightly mixed bag – I think if you designed an app for controlling a soundbar as its first priority, rather than playing music as its first priority, you probably wouldn’t bury settings like the Speech Enhancement that far down in the settings.

I’d love to see Sonos change how it approaches its Now Playing screen when you’re connected to HDMI, so it puts more emphasis on making settings available to you instead of a lack of artwork.

But setting it up was smooth, and most people won’t need to go back into the app, especially if you won’t connect other devices. As I mentioned, I found the speech clear enough without using the enhancement, and I didn’t think the EQ needed adjustment. TruePlay will be suggested as part of the setup too, and it worked with my remote (over HDMI-CEC, but infrared is also enabled by default) out of the box with no tinkering required.

• Premium, but competitive price
• As good sound as you can get for the price
• Surround-ready products available around the same price

The Sonos Arc Ultra isn’t cheap, but if you want powerful, expansive, clear Dolby Atmos sound from a single inoffensively-designed soundbar, you can’t do better for the price – as long as you’re not tight on HDMI ports.

You can get a full surround setup for a similar price to this, but the core Sonos Arc Ultra is designed for people who don’t want to deal with having four boxes including a hefty subwoofer. And I think it’s the best, most cinematic single box you can add to your TV for the price, making it very strong value.

But as I say, if you’re already filling your HDMI ports, that value is harmed, because the Arc Ultra may create a new problem for you. For the price, it should really offer you the solution.

• Value score: 4 / 5

Should I buy the Sonos Arc Ultra? Buy it if...

You want the best sound from a single-unit soundbar
At this price, and without extra satellite speakers, nothing beats what the Sonos Arc Ultra can do.

You want clearer speech and Dolby Atmos cinematic effects
The Arc Ultra is a big step up over the Arc for dialogue, and boosts Dolby Atmos positioning skill at the same time.

You want Sonos' extra skills
Part of a multi-room music system? Check. The ability to add other speakers in the future to improve the sound? Check. TruePlay room tuning? Sound check.

Don't buy it if...

You're short on HDMI ports
No HDMI passthrough really could be a dealbreaker.

You want the best value sound and could have more than one box
The Sonos Arc Ultra is very good value for a one-box system, but if you can live with more hardware, you can get bigger sound for the price.

You're a home theater purist about DTS
Sonos' continued lack of DTS support will irk those those with physical media in DTS:X.

Sonos Arc Ultra review: Also consider

Sony Bravia Theater Bar 8
We didn't rave about this soundbar overall in our Sony Bravia Theater Bar 8 review, but it's cheaper than the Sonos Arc Ultra and offers 4K 120Hz HDMI passthrough, so it might be the most practical option for some people – or its more expensive sibling, the Sony Bravia Theater Bar 9 is the beefier-sounding option, but is pricier than the Sonos.

Sonos Beam 2
Want to go even more compact and have Sonos' options for expansion? The Beam 2 delivers surprisingly full sound for such a compact soundbar, and supports Dolby Atmos, but not with anything like the effectiveness of the Arc Ultra. But it's half the price, so swings and roundabouts – definitely read our Sonos Beam 2 review if you want to know more.

Samsung HW-Q990D
Look, if you can find this full Dolby Atmos surround system for close to the Sonos Arc Ultra's price, know that it will give you a truly mind-blowing Dolby Atmos home theater experience – as long as you can live with four boxes instead of one. We gave it five stars in our Samsung HW-Q990D review.

How I tested the Sonos Arc Ultra

• Tested over a week
• Tested at home, in my usual setup
• Tested with Sonos surround configurations

For the crucial portion of this review, I used the Sonos Arc Ultra at home, in the same setup where I usually use the original Sonos Arc, so I had a good point of direct comparison. I directly compared the sound of the two bars to gauge the difference, but mostly I just used the Sonos Arc Ultra for my normal viewing, which included 4K Blu-rays and streaming. I listened in both lossless quality and compressed, as well as in Dolby Atmos, regular 5.1 surround sound, and in stereo.

As mentioned above, I tested the Sonos Arc Ultra on its own mainly, but also tried it with the Sub 4, and then with the Sub 4 and different Sonos rear speaker options.

I also tested a Sonos surround setup for a short time compared to the Samsung HW-Q990C in TechRadar's TV testing rooms. On our corporate Wi-Fi systems, I had connections problems that meant I couldn't do longer-term comparisons; at home, I use a Google Nest Home mesh Wi-Fi system and had no problems with the Sonos app or network connectivity.
