We first heard the Focal Mu-so Hekla at CES 2026 in Las Vegas, and even in the less-than-ideal acoustics of a hotel suite in Sin City, it made a strong case for itself; wide, controlled, and far more composed than most “one-box” solutions pretending to be high-end. Fast forward to AXPONA 2026 in Chicago, and Focal and Naim doubled down, dropping the Hekla into a mock living space embedded inside their sprawling ballroom setup, surrounded by much of their product range, and letting it breathe in a more realistic environment.

And right from the start, they’ve been very clear: don’t call it a soundbar. After spending time with it in both settings, that stance holds up. Yes, it lives under a TV and replaces a rack full of gear, but the intent is different. This is a performance-first, all-in-one wireless speaker built around Naim’s Pulse platform, not a convenience play dressed up with Atmos logos. Call it what you want, but if you’ve actually heard it, you’ll understand why they push back.

Wait. If It’s Not a Soundbar…How Does This Thing Work?

Named after Iceland’s Hekla volcano, the Focal Mu-so Hekla isn’t chasing the usual lifestyle brief. Focal and Naim built this around output and control first, with the convenience piece trailing behind. Inside is a 15-driver array firing forward, sideways, and upward, backed by Naim’s Pulse platform and Focal’s ADAPT room correction—technology that first showed up in the Focal Diva Utopia. The goal is straightforward: create a believable, room-specific soundfield from a single enclosure without leaning on smoke and mirrors.

Setup doesn’t waste your time. ADAPT runs through the app with a short calibration routine; basic room inputs, a few test sequences, done. From there, Sphere Music and Sphere Movie modes adjust how the system presents content rather than just piling on effects. In practice, it works. Dolby Atmos material has real width and height, and it doesn’t collapse into a front-loaded blob. It’s immersive enough that you start checking for speakers behind you. There aren’t any. Bass digs deeper than expected; down to around 30 Hz within 3 dB, so it doesn’t feel incomplete out of the box.

That said, you’re not locked into a one box life sentence. You can add a subwoofer, two in fact, and while Focal would clearly love for you to keep it in the family, the system isn’t that rigid. If you already own something from SVS or another brand, it’s not going to throw a tantrum. Adjust it properly and you’ll get more scale and weight without breaking the core presentation.

Day-to-day use is where it keeps things grounded. Streaming, internet radio, voice control, smartwatches; it’s all here, but none of it gets in the way. The large physical volume dial handles the basics without forcing you into an app every five minutes. It also works as a hub within the broader Mu-so ecosystem, letting you link additional Mu-so speakers throughout the home for a proper multiroom setup. One box under the TV if you want simplicity, or a full-house system if you don’t.

The enclosure feels considered without trying too hard. The Focal Mu-so Hekla uses brushed, anodized aluminum with a mix of brushed and bead blasted finishes that give it some texture without overdoing it. Focal is clearly sticking to the same playbook as the Focal Diva Utopia; clean lines, solid materials, and a sense that everything is there for a reason. It’s refined, but not in a way that calls attention to itself or tries to win design awards at the expense of usability.

The circular control panel sits slightly raised and activates via proximity, offering direct access without disrupting the overall layout. Its form references the Hekla volcano, including the white top surface, but it remains integrated into the design rather than drawing attention to itself. If you are familiar with the Naim Uniti Series of network amplifiers, the design choices will feel very familiar.

The front grille is finely perforated to maintain acoustic transparency while keeping the visual presentation understated. Around back, Naim incorporates its signature heat sink structure, which manages thermal performance while also housing wireless connectivity.

Bluetooth here is strictly one way traffic. The Focal Mu-so Hekla will happily receive from your phone, tablet, or computer, but that’s where it stops. No sending audio out to headphones, no Auracast, and no aptX Lossless. If you were hoping this would double as a wireless hub for late night listening, it won’t.

Inside the Focal and Naim ecosystem, things open up. Multiroom and Party Mode work across compatible streamers through the app, and the latest App 8.0 update folds in a proper radio player with thousands of internet stations, including Naim Radio. It’s a cleaner, more integrated approach than juggling third party apps that may or may not behave.

If you want to take it beyond the room, you still can; just not directly from the speaker. Focal Bathys and Focal Bathys MG can tap into those same stations by streaming from your phone over Bluetooth.

Immersive Sound That Actually Fills the Room Without Rear Speakers

What stands out immediately is how composed the Focal Mu-so Hekla sounds with both stereo and multi channel material. There’s no sense of it reaching or overextending to create the illusion. Surround mixes, whether film or music, are presented with control. Effects move when they’re supposed to, not because the system is trying to impress you. Everything stays anchored. Imaging doesn’t drift. It holds its shape.

That’s what makes it work. The sense of space is real, not inflated, and it scales in a way that’s unusual for a single enclosure. In the Focal and Naim demo space at AXPONA, which was packed well beyond what it was designed for, the presentation still filled the room without collapsing. You could see it on people’s faces. That moment where they stop talking and start paying attention.

Low end was clearly influenced by the size of the space, but it still carried weight and control. Not overblown, not thin. Just enough to keep everything grounded. Vocals stayed locked in, with real presence and body, while the top end had the kind of detail and energy that cuts through without getting sharp. It doesn’t try to overwhelm you. It just stays in control and lets the mix do the work.

The pricing is what makes you stop and look twice. At $3,600, the Focal Mu-so Hekla lands in a spot that doesn’t quite follow the usual script. The Naim Uniti Atom isn’t that far behind in price, and that’s a component system starter. This is everything in one chassis. Most curious.

So who is this actually for? Not the person chasing separates and a rack full of gear. This is for someone who splits their time between music and movies and refuses to compromise on either. Someone who wants access to the major streaming platforms, cares about sound quality, but also values a clean room and fewer cables. The kind of buyer who wants it to just work, and work well without turning setup into a weekend project.

And physically, it fits. It won’t look out of place under a 75-inch TV. If anything, the scale of the soundstage makes the footprint feel justified. It sounds bigger than it looks. Much bigger. For a company that sells two-channel systems that can ascend into the $250,000 range or even higher — the Mu-so Hekla is rather strong bargain at a show that didn’t offer very many.

The robot uses Bluetooth to communicate with your phone and uses 2.4-GHz Wi-Fi to connect directly to your home network for over-the-air updates (but not real-time management). Onboarding requires connecting to a temporary network on the device and bridging it to your home network, a quick process that gave me no trouble during setup. Firmware updates will likely be available, but note you’ll need to check the Device Information menu for them. Mammotion didn’t proactively push or suggest any updates during my testing, and these over-the-air updates often required multiple attempts to install successfully.

The app is decidedly limited, allowing you to select from the standard four operating modes and make a few small additional adjustments, including configuring the maximum speed of the robot and opting into a couple of beta features. These include a “Turbo Cleaning” mode that increases the power of the suction at the expense of battery life, and an option to improve the way the unit cleans steps and platforms. (Why this feature isn’t always on is a mystery.)

Leaves Left Behind

Throughout my test runs, I saw fairly consistent performance results. The Spino E1 offers acceptable cleaning capabilities, though it’s far from perfect. With synthetic leaves, the unit averaged a cleanup rate of only about 80 percent, leaving behind a significant amount of material uncollected. This material wasn’t just isolated to corners and steps; it was scattered all around the pool. I also noticed the unit cleaned steps and platforms well, but it struggled heavily with obstacles, particularly at the waterline.

I saw similar results with organic debris, and the E1 struggled particularly with smaller particulate matter like dirt. On one run, I could best describe the pool as looking a bit like some of the debris had been smeared around on the pool floor instead of sucked up into the debris basket. All of this is unusual and suggests not that the unit has coverage issues, but rather that the device simply may be underpowered.

Good news: The Turbo Cleaning mode available through the app was visibly more effective and bizarrely did not impact battery life at all. The bad news is that this option, still in beta, has to be manually activated in the app before each run of the robot. Hopefully, Mammotion will simply make Turbo Mode the default soon.

When finished, the Spino E1 climbs the pool wall and waits by the waterline for collection—at least momentarily. The problem is that the robot doesn’t push a notification via the Mammotion app to alert you when a cleaning cycle is done, and since the robot has to run its propulsion jets to float, you only have a limited time (about 10 minutes) before the battery dies and the robot sinks. A hook is included in the box to aid with pole-based retrieval in this event.

Morgan Dreiss, a copy editor in Orlando, has severe ADHD that they say requires them to always be “doing at least three things at once.” The result? A daily average screen time of 18 hours and 55 minutes.

“I’m reading a book or playing a game pretty much from waking to sleeping,” Dreiss tells WIRED. What they read comes from the library app Libby, so the books count toward overall screen engagement. Dreiss currently keeps their phone’s autolock feature disabled so they can continuously run a mobile game that pays out $35 for every 110 hours logged. (They’ve earned about $16 so far.)

For years, studies have brought forth worrying data about the potential negative effects of excessive screen time on both physical and cognitive health. Concerns over the neural development and mental health of young people glued to their phones have led to major legislative and courtroom battles; recently a jury found Meta and YouTube liable for designing their platforms with addictive features.

While the question of whether one can be clinically “addicted” to something like social media remains a subject of fierce contention, there seems to be a broad consensus in this decade that people would be better off scrolling less. On the more extreme end, there are virtual communities that share strategies for ditching smartphones and digital detox retreats where no notifications can find you.

Yet there are those, like Dreiss, who resist the emerging common wisdom about reducing screen time. You might call them “screenmaxxers.” It’s not that they necessarily have some totalizing concept of their habits; journalist Taylor Lorenz is likely in the minority of screenmaxxers eager to put the screen directly inside her brain, as she recently confessed to WIRED. It’s just that, for various reasons, they’re on their devices pretty much all the time, and they don’t see that as a problem whatsoever.

Part of the equation, of course, is work. Corina Diaz, 45, who lives in a remote forested region of Ontario, Canada, works in video game marketing and does influencer management for a game publisher. “So, a lot of screen time,” she says.

Diaz met her husband online in 2005 and had a child three years ago—her screen time increased when she was awake at strange hours because of her newborn, she says.

But Diaz has sought friendships online since the 1990s, when that meant availing herself of tools like Internet Relay Chat and bulletin board systems. “I’ve always felt screens, phone or otherwise, connected me to things I care about,” she says. “In particular, niche social groups that don’t have great mainstream visibility.” Now that she lives two and a half hours outside Toronto, the closest major city, her screen is “a bit of a connection lifeline,” she says.

Daniel Rios is in a similar position. A computer programmer, he lives in the South American country where he grew up after having lived abroad for years. Most of his friends moved away and didn’t return.

As a result, Rios keeps in touch with people over Discord, his primary social outlet. Not living in a city, he doesn’t go out all that much, and screens fill his days—though he says it’s “hard to quantify” exactly how many hours it all adds up to. “When I’m not working at the [desktop] computer, I’m playing at the computer or watching TV,” he says. “If I’m not at the computer, I’m looking at my phone. If I’m not doing any of the above, and I’m out of the house, I’m still probably listening to something on my phone.”

For decades, the ERP “playbook” was a familiar exercise in endurance: organizations would mobilize an army of consultants, brace for years of disruption, and spend millions on a monolithic system designed to last a decade.

Success was binary, the system either switched on, or it didn’t, while adoption and agility remained secondary concerns. But as we enter the AI era, this traditional model has reached a breaking point.
