Hackers access GitHub, download codebase in Grafana Labs breach

Published

on

The hackers have since demanded a ransom payment from Grafana Labs to prevent the release of its codebase.

US software company Grafana Labs has confirmed a breach in which hackers gained access to the organisation’s GitHub system after stealing a private token and downloaded the company’s codebase.  

A provider of an open-source and visualisation web app with 25m users and more than 7,000 customers, including Anthropic, Bloomberg, Nvidia, Microsoft and Salesforce, Grafana Labs has a presence in more than 40 countries. 

In a statement posted on LinkedIn, Grafana Labs said, “Our investigation has determined that no customer data or personal information was accessed during this incident, and we have found no evidence of impact to customer systems or operations.

“We immediately initiated forensic analysis and we believe we’ve identified the source of the credential leak. We have since invalidated the compromised credentials and implemented additional security measures to further secure our environment against unauthorised access.”

The intruder or group – whose identity has yet to be confirmed – sent Grafana Labs a payment demand, threatening to release the stolen code. However, the organisation has refused to comply with the request.

Grafana Labs said, “Based on our operational experience and the published stance of the Federal Bureau of Investigation, which notes that ‘paying a ransom doesn’t guarantee you or your organisation will get any data back’ and only ‘offers an incentive for others to get involved in this type of illegal activity’, we have determined the appropriate path forward is to not pay the ransom.”

The company also stated that as part of its standard security practices, it will share information as part of a post-incident review once the investigation is complete.

Earlier this month, Taiwanese electronics manufacturer Foxconn confirmed a cyberattack affecting its North American operations, after a hacking group claimed to have stolen 8TB of data from it. Nitrogen claimed that the extracted files included confidential instructions, internal project documentation and technical drawings related to projects involving Intel, Apple, Google, Dell, Nvidia and other companies.

And prior to that, Instructure, the parent company behind Canvas, the education management platform reportedly hacked by ShinyHunters, reached an agreement with the cyber gang in which the group has returned stolen data, deleted copies and agreed not to extort client institutions affected in the hack – for unknown compensation.

Alleged Scattered Spider hacker extradited to the United States

Published

on

Spider hacker

A dual United States and Estonian citizen has been extradited to the U.S. to face charges alleging he was a member of the Scattered Spider hacking collective.

19-year-old Peter Stokes (who used the online handles “Bouquet,” “Spencer,” and “Jordan”) was arrested in Finland on April 10 while attempting to board a flight to Japan at Helsinki’s airport and is accused of having helped extort millions of dollars from multiple high-profile companies worldwide.

According to court documents, Stokes was involved in at least four Scattered Spider breaches (including a March 2023 hack of an online communication platform, when he was 16 years old) that led to victim companies being asked to pay millions of dollars in ransoms.

The list of victims breached with the suspect’s help also includes an unnamed multibillion-dollar “luxury item retailer” in May 2025, when the hackers allegedly called the company’s IT helpdesk, posing as employees, to reset credentials and gain access to administrator accounts.

While the threat actors demanded an $8 million ransom, claiming to have 100 gigabytes of stolen data, the company refused to pay. However, it still incurred over $2 million due to operations disruption and remediation costs.

Stokes now faces charges of fraud, conspiracy, and computer intrusion and has remained in custody after appearing in federal court in Chicago on Tuesday.

​”The criminal complaint charges Peter Stokes with membership in Scattered Spider, a hacking group that has been involved in over 100 network intrusions, resulting in more than $100 million in ransom payments and millions more in damages to the victims,” said Assistant Attorney General A. Tysen Duva on Wednesday.

“Scattered Spider has repeatedly targeted U.S. companies, extorting employees, inflicting millions of dollars in losses, and disrupting essential operations,” added Assistant Director Brett Leatherman of the FBI’s Cyber Division.

Scattered Spider (also tracked as 0ktapus, Octo Tempest, Scatter Swine, UNC3944, and Muddled Libra) emerged in 2022 as a loosely knit hacking collective mainly composed of teenagers and young adults from the United States and Great Britain.

They are known for using a blend of social engineering, targeted multi-factor authentication (MFA) bombing (aka MFA fatigue), and SMS credential phishing attacks to steal user credentials and sensitive documents for extortion leverage after breaching their targets’ networks.

According to prosecutors, they commonly use the Genymobile Android emulator during their MFA attacks and have also deployed DragonForce encryptor in ransomware attacks against UK retail companies.

Scattered Spider’s list of victims includes many high-profile organizations, including Caesars, MGM Resorts, Riot Games, DoorDash, Reddit, MailChimp, Twilio, Allianz Life, Transport for London (TfL), multiple UK retailers such as Co-op, Marks & Spencer (M&S), and Harrods, and, more recently, WestJet and Jaguar Land Rover (JLR).

Apple is very confident about the iPhone Ultra foldable it seems

Published

on

Apple appears to be growing increasingly confident in its first foldable iPhone. A new report claims the company has raised its production plans for the long-rumoured iPhone Fold to 10 million units for the remainder of 2026.

That’s according to Nikkei Asia, which previously reported that Apple was targeting between seven and eight million foldable iPhones this year. The new figure aligns more closely with an earlier 11 million-unit claim from leaker Digital Chat Station.

If the latest estimate proves accurate, it could signal that Apple is preparing for a much bigger launch than many expected.

Previous rumours suggested manufacturing challenges around the foldable display, hinge and internal circuit board could limit production. However, increasing orders would indicate those issues may now be under control.

Advertisement

The report also offers another clue about timing. Since the 10 million figure covers Apple’s 2026 production plans, it adds weight to speculation that the iPhone Fold could still debut alongside the rest of the iPhone lineup in September instead of slipping into 2027. Some rumours have suggested it could be delayed. That said, Apple could still unveil the device this year and delay shipments until later if production runs into problems.

Advertisement

Foldables are also likely to become a much bigger part of the wider market next year. Separate industry estimates suggest Apple’s first foldable could account for 29% of global folding display orders in 2026. This would put it close to Samsung’s projected 31% share and ahead of Huawei’s estimated 24%.

The report arrives alongside broader claims about Apple’s production strategy. The company is said to be planning more than 220 million iPhones across its entire range in 2026. At the same time, Apple is asking suppliers to reserve additional iPhone 17 components to reduce the risk of shortages.

Advertisement

Apple’s launch schedule could also look a little different next year. Rumours continue to suggest the standard iPhone 18 may move from its traditional September slot to spring 2027. This could leave more room for premium models, including the iPhone Fold.

For now, Apple’s foldable plans remain unofficial. But increasing production targets from around eight million to 10 million units suggests the company is becoming more confident. Its first folding iPhone could be one of its biggest launches in years.

Bose Lifestyle Ultra Speaker: Two-minute review

It may not always be among the first brands to get a particular type of product to market, but you can usually rely on Bose to have done a proper job by the time it gets around to it. And on paper, that seems to be exactly what’s happened with this new Lifestyle Ultra Speaker — it’s priced and specified to meet the market-leaders head on, and has one or two points of difference to try and make its case even stronger.

The looks, for instance, are just distinct enough from the usual ‘cylinder of sound’ design to stand out in a showroom. The specification, which includes a 38mm mid/high driver angled to fire upwards through the top of the cabinet, promises authentic spatial audio performance where many a rival relies on digital sound processing in an effort to achieve the effect. And the appearance of Alexa+ as a voice assistant marks the first time a non-Amazon product is using the technology.

How To Claim A WhatsApp Username

Published

on

Get ready to navigate a free-for-all of social media handles.

Earlier this week, Meta announced that its popular messaging platform WhatsApp would introduce usernames. These handles can replace people’s phone numbers, allowing them to keep that personal contact info more private if they wish. The username feature is not active yet, and it will see a global rollout over the coming months. 

However, reservations for usernames are now open, and already there’s been a scramble for people to secure how they want to be known to their friends and family as well as to the app’s broader community. If you want to have the same tag on all your platforms, you’ll want to act quickly. Here’s what you need to know to lock down your WhatsApp username.

Advertisement

How to reserve a username

For now, the username reservations are only available on the mobile versions of WhatsApp. If you keep your app updated, you may receive a notification when usernames are available for you to reserve. If you think you missed the notification or just want to get to the menu on your own, here are the steps to take:

For iPhone

  • Tap the You button
  • Tap your profile
  • Pick “Create Username” or “Reserve Username” (The option may vary based on the stage of the rollout.)
  • Tap Save > Done

For Android

  • Tap the three-dot menu
  • Tap Settings
  • Tap your profile
  • Pick “Create Username” or “Reserve Username” (Again, what you see depends on what’s available to you.)
  • Tap Save > Done

Restrictions on WhatsApp usernames

As with most other social networks, your username must be unique. That means no matter how much you might want to be known as GlitterQueen4Eva, if someone else snatches that title first, you’ll need to come up with an alternative. The only way you might be lucky enough to grab an already-taken username is if that person opts to change what they have reserved, which can happen. Once a claimed handle has been changed or deleted, that name goes back up for grabs after 14 days. Meta hasn’t specified how many times a person will be allowed to change their handle, but a limit will be applied at some point.

Advertisement

In the above menus, if you don’t want to create a new ID for yourself, you’ll see an option to use your same username from Facebook or Instagram. Assuming nobody else has already snagged it, you can lock that name down. You may want to go with an original name for WhatsApp if privacy is your goal for a username.

In more practical terms, a username must be between three and 35 characters. They can contain lowercase letters, numbers, underscores and periods. You won’t be allowed to have a username of all numbers, and “restricted words or phrases” also won’t be permitted.

Advertisement

Use common sense to avoid scams

Meta has some measures planned to ensure that messages are coming from people you know, such as an authorization key for people contacting you by username for the first time. However, there are concerns that putting unverified names to accounts could increase the odds of scammers convincing their targets that they are somebody else. While Meta won’t be allowing just anyone to claim that they’re Beyoncé or Tim Cook, the company hasn’t explained if or how it will check for copycats. Although it’s safe to assume the real Taylor Swift won’t suddenly message you desperate for money, social media scams have cost unsuspecting people billions of dollars in the US alone.

Meta is already facing pushback against the global rollout in India. Reuters reported that the Indian government is calling for Meta to freeze the rollout until it can provide additional justifications for the feature and how the company will combat the elevated risks of fraud. India is the largest market for WhatsApp with more than 500 million users.

Opera rolls out Paste Protect feature to fight ClickFix attacks

Published

Opera rolls out Paste Protect feature to fight ClickFix attacks

Opera has introduced Paste Protect, a security feature designed to block ClickFix-style attacks that trick users into executing malicious commands through social engineering.

ClickFix is a widely used technique where victims are deceived into copying dangerous code or commands to the clipboard and then executing them in the command-line interface.

Typically, the ruse is a verification process or some form of problem-fixing instructions. However, they are only designed to trick the target into performing dangerous actions.

image

The commands execute with the user’s privileges, bypassing existing security defenses, and many times lead to the delivery of information-stealer malware.

The method is to popular with threat actors that Apple recently introduced a security feature designed specifically to detect risky pastes in the Terminal and block them before alerting the user.

Advertisement

Opera’s approach with Paste Protect is similar: it blocks harmful commands before they are copied to the browser clipboard.

The new security mechanism leverages Hijack protection, introduced in 2021, which can detect attempts from external applications to replace copied content (e.g., URLs or bank account numbers) with malicious alternatives, as well as a new component called Injection protection.

Injection protection blocks potentially harmful commands before they reach the clipboard, regardless if the action is initiated by the user or a website they visit.

Opera says it uses platform-specific detection rules to scan copied content for patterns commonly associated with malicious scripts and commands, supporting Windows, macOS, and Linux.

Advertisement

When Paste Protect detects suspicious clipboard content, it blocks the copy operation, displays a warning, and shows a red security indicator in the browser’s address bar.

“If a potential threat is detected, the copy action is automatically blocked,” describes Opera.

“You’ll see a popup explaining what happened, and a red warning icon will appear in the address bar.”

In such cases, users can view the first 120 characters of the blocked script, and they can approve the process of copying it after a 5-second timeout.

Users will also have the option to create allow-lists with trusted websites to minimize the friction from repeated blocks by Opera’s new security system.

“If you really know what you’re doing, for example if you’re a developer who regularly copies scripts or commands from trusted sources like GitHub, you can also set trusted websites where it’s allowed to copy scripts by selecting “Always allow from this site” in the popup,” explained Opera.

Paste Protect is enabled by default in the latest Opera release, and users can manage it through Settings → Privacy & Security → Paste Protect.

As a general recommendation, users should avoid executing commands they found online that they don’t fully understand and treat all such prompts with suspicion.

3 Silverado Engines You Should Steer Clear Of

Published

on





Ever since it entered the market in 1999, the Silverado has been the flagship truck for Chevrolet, constantly going toe-to-toe with the likes of the F-150. Priding itself on all-around practicality with plenty of comfort inside to match, the full-size Chevy has long offered one of the most versatile selections of trim levels, which is even more so the case for the newer models. Throughout the truck’s life, we’ve also had the choice between a few different engine types, which is perhaps the most crucial choice of all. Not only does it dictate how capable the truck can be, but in the Silverado’s case, some engines ring louder alarm bells than others.

Since the Silverado has been around for a while, and the newest models get plenty of praise for being reliable, but that wasn’t always the case. There are plenty of reports and data from owners to give us an idea of which engine options have the most issues, and despite the difference in construction, many fall victims to the same problems.

Advertisement

2014-2018 5.3L V8

For the 2014 model year, Chevrolet introduced a revitalized version of the Silverado, bringing nearly every aspect of the truck up to current standards. It sported a meaner look atop the new platform, but perhaps the biggest change was under the hood, with a selection of entirely new engines available. These were the first of the Ecotec3 engines, and while some, like the 4.7L V6, don’t have as many overall issues, the same can’t be said for the mid-spec 5.3L V6 engine. Unfortunately, the problems of the 5.3L remained relevant throughout the generation, until 2018. It’s certainly worth checking any 2014-2018 model years for these issues.

Advertisement

On CarComplaints.com, the 2014 model year comes out ahead for being the most troublesome. Electrical issues and build quality help out with that, but the engine itself is another major pain point. Specifically, the active fuel management system that was used in this engine is well-known for causing all sorts of issues. Owners report overly excessive fuel consumption, which can subsequently cause larger failures that’ll cost a hefty amount to fix. Another problem directly related to the AFM system is the lifters failing, which comes up plenty of times on the NHTSA website. Engine failure can easily follow. As this active fuel management system was used on every one of these engines from 2014 to 2018, you may want to avoid it, unless it’s been disabled permanently.

Advertisement

2019-2024 6.2L V8

Moving into the 2019 generation of Silverados, Chevrolet opted to keep the engines from prior models and giving them a few updates. A couple of new engines were also introduced, but looking at the reported issues for these Silverados, it’s the existing V8 that proves to be the most troublesome. In place of the AFM system found in the previous generation, a new iteration, the dynamic fuel management system, was designed to refine its performance. While it may have done so, it wasn’t issue-free. Far from it, in fact.

On top of the potential DFM issues that cause similar problems to those found in older engines, things got much worse for 6.2L-powered Silverados built between 2021 and 2024. A massive recall was put out for every Chevrolet that uses this L87 V8, not just the Silverado, due to crankshaft failures and faulty connecting rods. On the NHTSA website and CarComplaints.com, there’s no shortage of reports for this problem, often mentioning the notorious knocking leading to major engine failures if left untreated. A few specific instances also mention crank bearing issues for 6.2L Silverados built before the recall.

Advertisement

2007-2013 5.3L V8

While the engines introduced in the 2014 generation had their fair share of issues, it was the (previous) second generation and its problems that forced to GM try to fix the active fuel management. As a result, we think you should keep clear of the 5.3L engine that was used for the Silverado between 2007 and 2013. On the flip side, the smaller 4.3L V6 doesn’t have anywhere near as many complaints as the 5.3L, nor does the larger 6.0L, despite the latter also using the AFM system.

The majority of the submitted complaints for Silverados built between 2007 and 2013 revolve around excessive oil usage. Owners also reported cam and lifter failure soon after noticing the oil levels drop dramatically, as well as issues with the spark plugs. Similar to the ’14 to ’18 model years, this is an engine you should only consider if the AFM system has been deactivated, to save yourself from potential engine failures.

The Dune keypad device can be your meeting controller and more

Published

on

My biggest pet peeve with meeting apps is that each one has a different shortcut for muting your mic or turning off your webcam. It’s hard to remember which keys do what when you’re mid-meeting and trying to make a point or ask a question. I always wanted a physical, universal button for mute and camera control — something I could hit without thinking. Project Mirage’s Dune, a tiny, three-key aluminum keypad — about the size of a stick of gum — that plugs into your MacBook’s USB-C port, does just that.

The $119 gadget has three buttons, and it changes context based on what app you are looking at. For instance, in meeting apps and sites, it could be toggle mic, toggle video, and bring window to the front. For Excel or Sheets, it could be copy, paste, and undo. For Chrome, it could be refresh, jump to URL bar, and paste. You get the gist. Developers can also use it with apps like VS Code or GitHub to merge, approve, or close a pull request.

The startup builds each unit to match your specific Mac model, so it sits flush against the laptop with no gap underneath. If your ports are already in use, you can connect it through a dongle instead. Dune has no battery and needs no separate charger — it draws power straight from the MacBook.

Advertisement

Currently, the startup supports M2 Air or later and M1 Pro or later models of MacBook running macOS 15 Sequoia or a later version.

The device looks and feels nice, but I felt the keys had more resistance. Right now, it is easy to push a key by mistake. A few times, I mistakenly unmuted myself or killed my camera because my hand brushed the device while reaching for a water bottle or coffee mug. It shouldn’t be this easy to press a key.

Dune ships with a companion app for configuring shortcuts, either per-app or system-wide. Within a given app, you can assign a Dune key to a keyboard shortcut, a command, or a link that opens an app or URL.

Image Credits:Project Mirage

Through the app, Dune also syncs with your calendar and surfaces your next meeting a few minutes before it starts, so you can join, dismiss, or send an “I’m running late” message with one tap.

If you want deeper customization, you can write and run your own Python script. If you don’t code, Dune has an easy integration with Claude Desktop: You describe the shortcut you want in plain language, and Claude writes it and assigns it to a key for that app — no manual setup required.

Advertisement

I built a shortcut that, whenever I’m on a startup’s website, pulls up a quick brief on the company: its competitors, investors, and questions I might ask if I booked a meeting with them. For anyone whose job involves sizing up companies quickly — investors, founders, operators — it’s a task tailor-made for Dune. I also built one that converts images to JPEG so I can upload them quickly to WordPress or social platforms. Both were easy to build and needed no manual configuration, though getting a shortcut fully working still takes some back-and-forth with Claude, including debugging once you actually run it.

The app also has a marketplace, from where you can explore skills made by other Dune owners. If the marketplace takes off, it could become core to Dune’s growth and retention strategy — hardware as a thin front end for a Claude-powered skills ecosystem, where each new skill gives owners one more reason to stick around.

However, at the moment, there are only limited skills. Plus, there is no way to test out a skill without assigning it to the hardware button — ideally, the app would let you preview a skill before committing it to hardware. The startup also needs to proactively add more of its own suggested skills for different apps to its users.

Project Mirage’s device retails for $149 after its introductory price expires, and it’s a solid pick for anyone productivity-minded. MuteMe covers just mute/unmute, and Stream Deck offers business-focused macros, but Dune is easier to customize on both hardware and software.

ULTRASONE Launches Four Signature Headphones and the NAOS MICRO USB DAC, With S-Logic Still Doing Its Own Thing

Published

on

ULTRASONE has launched its largest product push to date, introducing four new wired headphones alongside the compact NAOS MICRO USB DAC. Rather than recycle one familiar platform with a new finish and some fresh adjectives, the German headphone maker is covering five distinct use cases: open-back listening, studio monitoring, compact audiophile listening, bass-heavy portable use, and better desktop or mobile source hardware.

The new lineup includes the Signature QUANTUM, Signature AERO, Signature MASTER PRO, Signature RAYVO, and NAOS MICRO. Preorders are open now, with deliveries expected to begin in September 2026. Wunderbar. The German national team probably wishes these had been available for the flight home after its rather early World Cup exit.

The Bavarian Headphone Brand That Put Space First

Founded in Bavaria in 1991, ULTRASONE has spent more than three decades building headphones for listeners who wanted something other than the familiar Sennheiser, Beyerdynamic, or AKG approach. The company established itself first in professional audio and DJ circles with its HFI and PRO ranges, before moving further into high-end consumer territory with its limited-edition Edition series.

The key to the brand’s identity has always been S-Logic. Rather than placing the driver directly in front of the ear canal, ULTRASONE positions it off-center so that sound reaches the outer ear first. The idea is to use the pinna, which helps people locate voices and instruments in real space, to create a broader and more speaker-like image inside a pair of headphones. It is not a subtle design choice, and neither are the results. Some listeners love the larger, more diffuse presentation; others find it unconventional. ULTRASONE has never seemed especially troubled by that.

Advertisement

The company’s reputation in high-end audio was cemented by models such as the Edition 9, Edition 8, Edition 10, and later Edition 15. These were not designed to disappear into the background. They combined premium materials, ambitious pricing, and a distinctly spatial sound that made them favorites among listeners looking for an alternative to the more conventional reference headphone hierarchy. The Edition 8, introduced in 2008, became one of the company’s best-known models by proving that a luxury closed-back headphone could work both at home and on the move without looking like studio equipment borrowed from 1987.

ULTRASONE also developed its ULE, or Ultra Low Emission, shielding system, which uses mu-metal protection around the drivers to reduce electromagnetic emissions. That feature has always been part engineering, part brand signature, but it underlined the company’s willingness to pursue headphone design from angles that other manufacturers generally ignored.

Signature QUANTUM Leads the New Lineup

ultrasone-signature-quantum-headphones
Ultrasone Signature Quantum

The Signature QUANTUM (€999) is the most clearly defined audiophile model in the group. It uses ULTRASONE’s 40mm GTC driver, previously found in the more expensive Edition 15 and Founders Series, with a gold and titanium-coated diaphragm, S-Logic5 spatial technology, and both single-ended and 4.4mm balanced LUMINOX cables in the box.

It is a closed-back, foldable design with 40-ohm impedance, 103dB sensitivity, and a claimed 6Hz–44kHz frequency response. At 364 grams without its cable, the QUANTUM is not pretending to be a featherweight travel headphone, but it is clearly intended to work beyond the listening room thanks to its passive isolation, aluminum hard case, and compact form factor.

ULTRASONE Signature QUANTUM Specs:

  • Headphone type: Wired, closed-back, foldable
  • Driver: 40mm GTC dynamic driver with gold-and-titanium-coated diaphragm
  • Technology: S-Logic5; Symmetrical DDF; Balanced Audio
  • Impedance: 40 ohms
  • Sensitivity: 103dB
  • Frequency response: 6Hz–44kHz
  • Weight: 364g, without cable
  • Ear pads/headband: Sheepskin-covered memory foam
  • Cables: 3m LUMINOX 3.5mm cable with screw-on 6.35mm adapter; 1.5m LUMINOX 4.4mm balanced cable
  • Other: Swivel ear cups; detachable screw-lock cable connectors; aluminum hard case

Open Back, Studio, and Bass Focused Alternatives

Ultrasone Signature AERO

The Signature AERO (€399) is the open-back option, built around a 45mm graphene driver and positioned for listeners who prioritize space, air, and detail with acoustic music, jazz, classical, and more carefully recorded pop. It looks like the model most likely to appeal to existing open-back headphone listeners who want a more spacious presentation without wandering into four-figure flagship territory.

ultrasone-signature-master-pro-headphones
Ultrasone Signature MASTER PRO

The Signature MASTER PRO (€799) takes the professional route. It features a newly developed 40mm titanium driver, LUMINOX internal wiring, and two high-end LUMINOX cables. ULTRASONE is pitching it toward engineers, producers, musicians, and studio owners who need a neutral and revealing tool for mixing, mastering, and critical listening. That is a crowded field, and it will have to earn its place against Beyerdynamic, Focal, Austrian Audio, Sennheiser, and the usual suspects who have been living in control rooms for decades.

ultrasone-signature-rayvo-headphones
Ultrasone Signature RAYVO

The Signature RAYVO (€299) is the least subtle entry of the group, which is probably the point. It combines aluminum ear cups, a foldable DJ-ready chassis, S-Logic5, balanced connectivity, and a more energetic tuning intended for bass-heavy genres including electronic music, hip-hop, techno, rock, and pop. ULTRASONE is not trying to sell this one as a mastering tool. Thank heaven.

NAOS MICRO Brings Dual DAC Hardware to the Mix

ultrasone-naos-micro
Ultrasone NAOS Micro USB DAC

The NAOS MICRO (€169) is an ultra-compact USB DAC with dual Cirrus Logic CS43131 converters, 3.5mm and 4.4mm headphone outputs, PCM support up to 32-bit/384kHz, and native DSD256 compatibility. ULTRASONE also describes it as providing dedicated headphone amplification, making it more than a basic USB-C adapter for listeners using laptops, tablets, or smartphones with wired headphones.

That could make it a logical companion for the new Signature lineup, particularly for anyone who wants balanced connectivity without dragging a desktop stack into a hotel room. ULTRASONE has not yet published detailed output-power specifications or U.S. pricing, however, so the real-world driving capability remains a question worth saving for an actual test.

ULTRASONE NAOS MICRO Specs:

  • Type: Compact USB DAC/headphone amplifier
  • DAC section: Dual Cirrus Logic CS43131 DAC chips
  • Outputs: 3.5mm single-ended and 4.4mm balanced headphone outputs
  • Format support: PCM up to 32-bit/384kHz; native DSD256
  • Construction: Aluminum-and-glass housing
  • Intended use: Smartphones, tablets, laptops, and compact hi-fi systems
  • Still unconfirmed: Price, output power into specific loads, gain settings, dimensions, weight, USB input type, and U.S. availability. 

The Bottom Line

ULTRASONE’s five-product launch is unusual because it is not built around one headphone platform dressed up for different audiences. The Signature RAYVO targets bass-heavy and DJ use, the open-back AERO focuses on spacious listening, the MASTER PRO goes after studio users, and the QUANTUM is the premium compact audiophile model. Across the range, ULTRASONE is leaning into its long-standing S-Logic spatial approach, balanced connectivity, and more specialized driver materials rather than chasing the same broad “reference” tuning with every model.

There is still plenty we do not know. The QUANTUM has the most complete specification sheet, but ULTRASONE has not yet published full technical data, U.S. pricing, or confirmed American dealer availability for the entire range. The NAOS MICRO is also intriguing, but without output-power figures it is impossible to say how it will stack up against the iFi GO bar, Questyle M15i, FiiO KA17, or Cayin RU7.

The headphone competition is equally specific. The AERO will face open-back models from Sennheiser, Meze, Beyerdynamic, and Austrian Audio; the MASTER PRO will have to contend with studio standards from Beyerdynamic, Focal, Shure, and Austrian Audio; and the QUANTUM enters a premium closed-back market dominated by Dan Clark Audio, Denon, Focal, Meze, and Audeze.

The differentiator is not merely a graphene or titanium driver. It is ULTRASONE’s attempt to offer a clearly different spatial presentation across multiple categories. Whether that translates into a real competitive advantage will depend on the tuning, comfort, durability, and how it performs.
