I was blown away by JBL's new Cove wireless speakers. They're finally available in Australia - and with a 20% discount via our coupon code.

I was blown away by JBL's new Cove wireless speakers. They're finally available in Australia - and with a 20% discount via its coupon code. JBL's new Cove M1, Cove P1 and Cove X1 wireless speakers were announced just over a month ago, and are now available to buy in Australia. The trio marks JBL's latest attempt to take on the likes of Sonos in the multi-room audio market, and having recently had the chance to see and hear the new speaker range up close, they certainly put up a decent fight. The trip share some interesting features: they can each be used as standalone units, or paired with a second unit of the same model for stereo sound. They can also be integrated into a wider home audio system alongside compatible JBL products, including the company's Bar Mk2 soundbars and Bluetooth-only speakers. And for any TechRadar Australia readers interested in the new models, you can save 20% thanks to an exclusive JBL AU coupon code. The range up close. In ascending order of size and power, the new trio comprises the Cove M1, Cove P1 and Cove X1. All three models are Wi-Fi enabled, with support for Google Cast, AirPlay 2, Spotify Connect, Tidal Connect, Qobuz Connect and Roon Ready. And, of course, they can also connect via Bluetooth. The Cove P1 and Cove X1 gain Dolby Atmos support too, while the P1 has the added benefit of being truly portable, thanks to its built-in battery. One immediate advantage is that you can use a pair as rear surrounds, connected to a Bar Mk2 soundbar, without having to worry about running power to them. Battery life is a claimed 14 hours on a single charge. If you do have access to power behind your seating position, the Cove P1 sits on a USB-C-powered charging base, similar to the Sonos Play - a pair of speakers which can also be used as battery-powered rear surrounds with the Beam Ultra soundbar. Another useful feature demonstrated to me was the P1's portability. Say you're watching sport on the main TV with the P1 acting as a rear surround speaker, but decide to move the party outside. You can simply ungroup the P1 from the home theatre setup, pick it up and take it with you. Once outside, press and hold the heart-shaped Moment button on top, and the P1 will resume playing the most recent content, so you don't miss any of the action. As for hardware, the Cove M1 has three 20mm tweeters and a single 4-inch woofer, with a total output of 110W. The Cove P1 gets three 30mm tweeters and a single 20mm tweeter to handle Dolby Atmos duties, along with the same 4-inch woofer, with a total output of 120W. The larger X1 gets four 30mm tweeters and two 90 x 120mm woofers, delivering a total of 200W. JBL wants to simplify multi-room audio. One of the main points JBL emphasised during my demo was ease of use. The company told me it recognises that one of the biggest barriers preventing consumers from investing in multi-room audio is the perception that it will be too difficult to get up and running. In response, JBL has developed the JBL One platform, which handles initial setup, speaker grouping and playback controls. During my demo, adding speakers to a network appeared relatively easy, with step-by-step instructions provided within the app. All available speakers are displayed on one screen, and you can select which ones you want to group together. One feature I found particularly neat is how quickly and easily you can remove individual speakers from a group to use them on their own. In my experience with Sonos, separating grouped speakers to use them as standalone units hasn't always been as straightforward as it should be, so JBL's approach is certainly welcome. Of course, I'll need to spend time with the JBL speakers in my own home before making any firm conclusions about how it compared with the likes of Sonos. A missing piece of the JBL puzzle. The Cove speakers slot neatly into a gap in JBL's lineup. The company is the king of Bluetooth speakers - just see its guide to the best Bluetooth speakers in Australia as proof - and it already has a comprehensive selection of soundbars. The Authentics speakers (the Authentics 200 currently tops its list of the best wireless speakers) are similar in that they're designed for home use, but they can't be used with other JBL speakers, and their retro styling may not be to everyone's taste. If the Cove speakers sound like a good fit for your home, you can save 20% thanks to its exclusive JBL Australia coupon code. Your unique code can be used on any full-priced item on the JBL Australia store, so you could even set yourself up with a complete home theatre system for less. JBL's new Cove M1, Cove P1 and Cove X1 wireless speakers were announced just over a month ago, and are now available to buy in Australia. The trio marks JBL's latest attempt to take on the likes of Sonos in the multi-room audio market, and having recently had the chance...

Sonos rolls out new Beam Ultra soundbar and Ace Ultra headphones.

Sonos rolls out new Beam Ultra soundbar and Ace Ultra headphones. Emma Wheaton | 01 Oct 2026 Sonos is betting on a new generation of home cinema and personal audio products in the premium consumer market as it launches the Beam Ultra soundbar and Ace Ultra headphones. The launch, which comes alongside a major update to its software platform, sees two new products arriving to expand Sonos' home theatre and headphone offerings. The company has positioned the devices as part of a more connected audio ecosystem, allowing sound to move between compatible products while keeping the company's focus on multi-room listening. The Beam Ultra retains the fairly compact sizing of the existing Beam but introduces a different acoustic architecture. Sonos says the soundbar delivers true 7.1.2 Dolby Atmos, with nine Class-D amplifiers and five tweeters. Two side-firing horn-loaded mid tweeters are designed to create greater stereo separation, while the system uses room-tuning technology to adapt its sound to its surroundings. Sonos has also introduced AI Speech Enhancement, which can be adjusted through the Sonos app to make dialogue easier to hear. And a Night Sound mode can reduce the intensity of louder effects while keeping quieter details. The Beam Ultra can connect via Wi-Fi, Bluetooth and HDMI eARC, and can be expanded with Sonos' wireless subwoofers and surround speakers. Sonos describes the product as a soundbar that can also become part of a larger home theatre system. The Ace Ultra is the second generation of Sonos' over-ear wireless headphones. The new model has a redesigned Sonos-engineered driver, adaptive ANC, spatial audio, Dolby Atmos support and up to 35 hours of battery life with ANC enabled. It also features USB-C and 3.5mm connections. A key feature for existing Sonos customers is Headphone Linking, which allows compatible audio to move between the headphones and Sonos home theatre products. That includes the ability to switch television audio from a soundbar to the headphones, allowing, for example, users to continue watching or listening to something without disturbing others. The Ace Ultra also has replaceable ear cushions and a replaceable battery, according to Sonos, while the company has increased the number of microphones and expanded its equalisation controls compared with the first-generation Ace. The launch comes as Sonos attempts to build momentum around its hardware and software ecosystem. The Beam Ultra and Ace Ultra arrive alongside Sonos 27, a major update to the company's audio operating system. According to Sonos, the platform is intended to make its connected system more capable across speakers, headphones and home theatre products. The Sonos Beam Ultra is priced at $1,099 and the Sonos Ace Ultra headphones cost $699.

Acme Revival sues Sonos over access to repair resources.

Acme Revival sues Sonos over access to repair resources. Complaint alleges Sonos failed to provide Acme Revival with parts, manuals, software, firmware, tools, and other resources needed to independently repair Sonos digital audio products. Denver, CO - Denver-based Acme Revival has filed a lawsuit against Sonos, Inc., alleging violations of Colorado's Consumer Repair Bill of Rights Act and the Colorado Consumer Protection Act. The complaint, filed September 16, 2026, in Denver District Court, concerns Sonos-branded digital audio products and Acme Revival's efforts to obtain the parts, documentation, embedded software, firmware, tools, diagnostic information, and other resources needed to diagnose, maintain, and repair the products independently. According to the complaint, Acme Revival has received approximately 45 requests from owners seeking diagnosis, maintenance, or repair of Sonos products. Acme alleges that it has been unable to accept, complete, or fully perform certain requested repairs because necessary repair materials have not been made available. The complaint states that, beginning around July 14, 2026, Acme made 14 separate written demands through Sonos' public-facing support channels and channels provided for legal communications while seeking access to repair parts and other resources under Colorado's Consumer Repair Bill of Rights Act. Acme alleges that Sonos either failed to respond to those requests or advised Acme that it was unable to provide the requested repair parts or resources. According to the complaint, on August 25, 2026, Sonos offered a paid replacement option and stated that it was unable to provide repair parts or resources for the product at issue rather than providing the repair materials Acme had requested. The complaint further alleges that Acme sent another written demand for repair access on August 31, 2026, and followed up on September 9 after receiving no response. According to the complaint, Sonos had not responded to the August 31 demand or the September 9 follow-up as of September 11, 2026. Acme alleges that Sonos did not provide a process through which it could order or otherwise obtain qualifying repair parts and resources on fair and reasonable terms. The complaint also alleges that Acme was not directed to a contractor making required parts available on Sonos' behalf. According to the complaint, Sonos manufactures or causes Sonos-branded digital audio products to be manufactured and participates in United States sales, support, service, warranty, legal, and repair-access functions associated with those products. The lawsuit also seeks to determine Sonos' obligations concerning particular repair materials associated with its products. The complaint alleges that Sonos possesses, uses, controls, or can obtain certain resources related to the hardware, software, firmware, digital functionality, diagnostics, maintenance, repair, updating, activation, or restoration of Sonos products. Acme states that the precise ownership, availability, and control of particular repair materials within Sonos' product and service operations are matters primarily or uniquely within Sonos' possession and knowledge and are expected to be addressed through discovery. Colorado's Consumer Repair Bill of Rights Act requires manufacturers of covered digital electronic equipment to make certain repair documentation, parts, embedded software, firmware, tools, and related resources available to owners and independent repair providers on fair and reasonable terms and costs. The complaint alleges that qualifying Sonos products are consumer digital audio equipment that depend, in whole or in part, on embedded digital electronics to function as intended. Depending on the model, the products may contain speakers, processors, circuit boards, wireless communication hardware, power supplies, charging components, connectors, embedded software, firmware, and other electronic or mechanical components. Acme alleges that its requested repairs concern the electronic, mechanical, software, firmware, and related consumer functionality of those products. The lawsuit applies its claims under Colorado's repair statute only to products that meet the statute's requirements, including applicable requirements relating to when the equipment was first manufactured, sold, or used in Colorado. According to the complaint, Sonos publicly provides product support and warranty services and offers manufacturer-controlled repair or replacement options for qualifying defective products. The complaint also cites Sonos' sale of Certified Refurbished products, which Sonos represents undergo testing and carry the same warranty as new products. Acme alleges that these activities support an inference that Sonos possesses, uses, or has access to technical, diagnostic, service, warranty, replacement, or other resources relevant to identifying and addressing defects in Sonos products. The complaint does not allege solely from Sonos' warranty or replacement services that Sonos necessarily possesses every particular component, schematic, tool, or document requested by Acme. According to the complaint, directing an independent repair provider toward a paid whole-device replacement does not itself make qualifying repair materials available or satisfy an otherwise applicable statutory obligation to provide repair resources on fair and reasonable terms. Acme alleges that Sonos' repeated failure or refusal to provide the requested repair materials through its support and legal channels reflects an ongoing repair-access practice rather than a single isolated interaction. According to the complaint, restricting access to qualifying repair resources can limit independent repair options and competition and may channel product owners toward manufacturer-controlled warranty service, replacement devices, or purchasing another product rather than repairing an existing one. Acme alleges that it has suffered lost repair revenue and profits, wasted diagnostic, intake, research, administrative, and communications time, lost present and future repair opportunities, and harm to customer relationships and goodwill. The complaint further alleges that the approximately 45 repair requests received by Acme demonstrate actual consumer demand for independent repair services involving Sonos products and that additional owners are likely to require diagnosis, maintenance, or repair as the products continue to be sold, supported, and used. Through the lawsuit, Acme Revival seeks declarations concerning which Sonos products are covered by Colorado law, whether Sonos qualifies as a manufacturer under the statute with respect to those products, and what qualifying repair resources Sonos must provide. Acme also seeks a declaration that directing an independent repair provider solely toward paid whole-device replacement or the purchase of another product does not itself satisfy a covered manufacturer's obligations under Colorado's Consumer Repair Bill of Rights Act. The lawsuit seeks permanent injunctive relief that, if Acme prevails and the court determines the statutory requirements apply, would require Sonos to make qualifying repair materials available on fair and reasonable terms and costs and maintain a reasonable and functional process through which Acme can request, order, access, and receive those materials. The requested relief also includes identifying any contractor through which qualifying materials are made available on Sonos' behalf, maintaining a functional communications process for repair-access requests, providing required updates to qualifying documentation, embedded software, firmware, or tools, and refraining from treating paid whole-device replacement as a substitute for statutory repair access where Colorado law requires such access. Acme also seeks actual damages or other damages available under the Colorado Consumer Protection Act, attorney fees, costs, interest, and other legal or equitable relief available under Colorado law. The complaint states that Acme may seek three times its actual damages if bad-faith conduct is established by clear and convincing evidence as provided by statute. The case is Acme Revival, Inc. v. Sonos, Inc., Case No. 2026CV33349 The allegations have not been adjudicated, and Sonos will have an opportunity to respond.

Sonos Beam Ultra review: Atmos soundbar sits in the price/sound sweet spot.

Sonos Beam Ultra review: Atmos soundbar sits in the price/sound sweet spot. By Chris Davies Sept. 22, 2026 10:15 am EST Add SlashGear on Google: Strange to think it's actually been five years since Sonos launched Beam (Gen 2). The intervening period has not only seen expectations for soundbars get more intense, but options for spatial audio - in music and video - more commonplace. With 5.1.2 support, the second-generation Beam could only pretend to deliver full Dolby Atmos, however; 2026's Sonos Beam Ultra has true 7.1.2 complete with upward-firing drivers. At $699 it's positioned above the $499 Beam (Gen 2), but below the $1,099 Arc Ultra. Like those models, Sonos offers it in either matte black or white. Soundbar aesthetics generally skew sober - it's the screen you're meant to be watching, after all - and the Beam Ultra is reasonably surreptitious. At almost 30-inches across it's about 4-inches wider than Beam (Gen 2), and it's very slightly deeper too. Sonos offers a $69 wall mount, or you can simply place it on your TV stand. Regardless, you'll want to make sure there's nothing interfering with the upper drivers (there's a Simulated Overhead Sound mode, using the front drivers for situations where there's less than 4-inches of space over the soundbar, but I'm not sure why you're buying Beam Ultra if you aren't going to take full advantage of its Atmos capabilities). Setup is simple, and there's a new Sonos 27 app. Sonos includes a power cable and an HDMI cable; you'll need to plug the latter into an HDMI eARC port on your TV. There's no optical audio adapter, as you get with the old Beam, but there is a USB-C port that supports line-in with an optional adapter. Inside, there's support for WiFi 6 (up from WiFi 4 before) along with Bluetooth 5.3. Setup is straightforward: plug in the HDMI cable and follow the app's instructions. After about five or ten minutes - depending how long the inevitable firmware update demands - audio from the TV is coming out of the soundbar. There's native 7.1.2 Dolby Atmos support, courtesy of five tweeters for the high and mid-ranges: a pair of side-firing horn-loaded mid tweeters for better stereo separation, one for the center channel for things like speech, and two upward-firing tweeters for the overhead parts of the soundtrack. Four low-profile woofers handle bass. Running through Trueplay tunes the Beam Ultra to the specific acoustics of the room it's in, using microphones in the soundbar itself (which can be disabled with a physical switch on the back); you can also manually tweak bass, treble, and loudness in the Sonos app. That software was recently revamped as part of the Sonos 27 push. It means the Beam Ultra will work with new Sonos Fabric features like Headphone Link - as launched on the new Ace Ultra headphones - but also generally tidies up the UI and makes it easier to see what's playing and where. As always, you can combine Beam Ultra into a speaker group for synchronized music playback in multiple zones. A welcome improvement in surround sound options. Night Sound trims the intensity of louder sounds while boosting quieter ones - making movies easier to listen to at night, without waking the rest of the house with sudden explosions - and there's also optional AI-powered speech enhancement that promises to spot human voices in the soundtrack and boost their clarity. As with other Sonos soundbars, though, you can augment all that with other speakers. If you want more bass, for example, a Sub or Sub Mini can be wirelessly paired. Likely more common are a pair of dedicated rear surround speakers. You'll need a matching pair of Era 300, Era 100, Sonos One, Sonos One SL, Sonos Five, or Symfonisk (Gen 2) speakers, or third-party speakers hooked up to a Sonos Amp; adding them is as simple as identifying them in the app. New, though, is the welcome ability to use select portable Sonos speakers as rear surrounds: it's part of what the company calls Sonos Fabric. At the moment that means a pair of Sonos Play or Move 2 speakers: once you identify them as the rear channels in the app, placing them - with line-of-sight to Beam Ultra - behind you sees the soundbar automatically identify them and route the audio accordingly. If you need them elsewhere, you can simply pick one (or both) up, and the soundbar will take over full TV audio duties. It's impressively seamless. If you have a pair of Sonos Ace or Sonos Ace Ultra headphones, you can use TV Audio Swap to wirelessly route the soundbar audio to the headphones instead. Dolby Atmos availability remains the pinch point. A soundbar is probably the easiest set-and-forget way to dramatically improve movie night. Once installed, for the most part the Beam Ultra just works: thanks to HDMI-CEC you can adjust its volume using the TV remote (or do so in the Sonos app). There's optional voice control, along with buttons on the top to adjust volume, play/pause, track skip, and to put the soundbar into Bluetooth mode (to play music directly from a phone or other Bluetooth source). Whether you get real Dolby Atmos - as in, with height data and the rest - is a little more complicated, since it depends on the content provider, your streaming device of choice, and your TV. Netflix, for instance, has Atmos support but only for select shows; you also need to subscribe to the most expensive Premium plan. Amazon Prime Video has Atmos titles in its catalog, but you have to subscribe to the Prime Video Ultra option. Disney+ has Atmos titles, but again, you'll need the more expensive "No Ads" package to get that audio. None of that is Sonos' fault, and it's a situation shared by all Atmos-capable soundbars. It's still a possible source of frustration, though, not to mention an added expense: a year's subscription to Netflix Premium and Disney+ Premium, for example, will cost you more than $500. That's not far off the price of the Beam Ultra itself. And while Atmos content is growing steadily, the majority of titles still don't support it. Beam Ultra sounds great, Atmos or otherwise. Find a compatible movie or TV show - Sonos' app flags whether you're listing to actual Dolby Atmos - and the Beam Ultra sounds great. On its own, with no extra speakers or subwoofer, there's a broad and crisply delineated soundstage, with a genuine sense that some of the soundtrack is coming from overhead. Obviously the space you're in will play a big role in that effectiveness: the soundbar is bouncing those overhead channels off the ceiling. The same goes for the side channels, which again expect to be bouncing off the side walls. Trueplay tuning can offset some of the impact of a less-rectilinear space, but it's not magic. In the right room, with the right content, Beam Ultra sounds fantastic. The soundtrack envelops you, not just from behind as Slashgear is familiar with from regular surround sound, but the sides and overhead. It's tech which flatters some genres more than others, undoubtedly - there are typically fewer helicopters whizzing past in arthouse movies - but with a thoughtful mix it's absolutely an improvement. You can adjust the height level of the overhead portion in the Sonos app. Sonos doesn't do simulated height effects that aren't present in the original mix (whether that's stereo or 5.1 surround), but that doesn't mean it's leaving any drivers idle. And it does undeniably sound more fulsome and expansive than the Beam (Gen 2) whether supplied Atmos or otherwise. The older soundbar's simulated version just can't keep up, and nor can its lesser driver count when the volume is cranked. Spatial audio isn't limited to video, of course: there's also spatial music, which is provided - again, on select tracks - through services like Apple Music. How it actually sounds is, I've discovered, very much a case of personal taste, and can vary on a track by track basis. Some spatial music mixes work better than others, and at times I find I do prefer the regular stereo. Still, there's no denying that the Atmos version is more encompassing and (for better or worse) more immersive. Sonos Beam Ultra verdict. Compared to the Sonos Arc Ultra I typically rely on for movie playback, the Beam Ultra is down on power and drivers, plus lacks full 9.1.4 support. That said, while I could crank the bigger (and much more expensive) soundbar louder, I hit the limits of comfort in the room before I felt like the Beam Ultra was really lacking. Sonos recommends its newest soundbar for "mid-size living rooms" 250-350 square feet in size, and that's before you add things like a rear surround speaker pair. I suspect that's not an uncommon situation, and arguably the greater strength of Beam Ultra is how it better bridges the gap between the Beam (Gen 2) and the Arc Ultra. Until now, if you wanted true Dolby Atmos support, Sonos' most expensive soundbar has been your only option. Add a couple of dedicated rear surround speakers - even smaller ones, like Era 100 SL - and you're looking at around $1,500. Meanwhile, you could get a Beam Ultra and a pair of Era 100 SL for about the same as the Arc Ultra alone. Compared to Beam (Gen 2), meanwhile, the improvements are more than just Dolby Atmos. It's a louder, better-sounding soundbar for both TV audio and music, and the addition of Bluetooth only makes it more flexible. For a lot of people, for whom Arc Ultra was overkill (however tempting), Sonos Beam Ultra will be sitting in a soundbar sweet spot.
