Every month seems to bring new sets of earbuds with longer battery life, new features, and more compact designs. As such, we can’t list everything we like. But if you’re still hunting, here are some other recommendations.
Nothing Ear (a) for $59: It has taken a lot for me to recommend a pair of ostensible AirPods Pro clones as the best earbuds for most people, but that speaks to just how much I actually like the Nothing Ear (a). These stylish little yellow earbuds come in a sleek, clear charging case, and they have excellent sound and decent noise cancellation for under $100 retail. I liked how easily they paired with Android and iOS devices and that the lightweight, compact design helped them stay comfortable during longer listening sessions. The larger, more expensive Nothing Ear are also good, but they don’t quite match the Ear (a)’s svelte figure.
Status Audio Pro X for $239: The multi-driver array inside these cool-looking earbuds from little-known brand Status Audio helps them rise above the rest when it comes to audio quality. A dynamic driver down low pairs with a set of Knowles balanced armatures for upper mids and highs, providing a ton of musical separation between instruments, and offering some of the best detail down low that we’ve heard in a pair of buds so far. The warm EQ works well with pop music and acoustic music alike, and the Pro X support Sony’s LDAC Bluetooth codec for near-lossless streaming quality. We compared them with the best from Sony, Bose, Sennheiser, and Technics, and found that the Pro X hold their own valiantly, with only the call quality coming in a touch below what others have to offer.

Technics EAH-AZ80 for $165: Technics’ follow-up to the fantastic EAH-AZ80 provides trickle-down driver technology from the brand’s hi-fi in-ears, the EAH-TZ700. The result for the AZ100 is even richer and more detailed sound that digs deep into instrumental textures to reveal new dimensions in old songs. The buds add new features like Dolby-powered Spatial Audio and Bluetooth LE Audio support for futureproofing, along with old favorites like three-device multipoint pairing and mildly improved noise canceling. The slimmer design isn’t as ergonomic as the AZ80 to my ears, but they’re still comfy, and battery life of up to 10 hours per charge with ANC lets you listen long past Bose and Apple buds. —Ryan Waniata
Beyerdynamic Amiron 300 for $150: These premium earbuds from Beyerdynamic look nondescript and sound fantastic, but they lack any of the superlative qualities of the buds on the list above. If you’re after a clean-looking pair of headphones with fantastic vocal definition, they’re worth considering.

Audio-Technica ATH-CKS50TW2 for $159: These buds from Audio Technica boast 15 hours of battery life with noise canceling on, which is the longest we’ve tested in a pair of earbuds. Despite a somewhat bulky appearance, they actually remain very ergonomic, with multiple pairs of included eartips to guarantee a good fit. A cool magnetic feature allows you to clip the buds together when they’re not in their wireless charging case to engage standby mode. These aren’t the best-sounding buds for the money, nor do they have the best noise reduction, but if you want a pair that will last you throughout multiple workdays (or one really long one), these are a great option. (Note: These have been in and out of stock on Amazon.)
Soundcore Space A40 for $45: While they’re no longer on our main list, the Space A40 are still some of my favorite buds for the money, providing good features, clear sound, and excellent noise canceling for their price class. They also look polished, with only their lack of auto-pause sensors betraying their low price.
Samsung Galaxy Buds 2 Pro for $100–$200: The Galaxy Buds 2 Pro are getting older, but they’re still among the best buds to pair with a Samsung phone. They don’t have the multi-device connectivity of our top pick for Android users, and their five-hour battery is looking pretty short these days, but they provide excellent sound quality, IPX7 waterproofing, and a distinctive design that doesn’t just ape the AirPods Pro. That makes them well worth considering on sale.

Sony Linkbuds Fit for $200: Sony’s Linkbuds Fit offer rich and punchy sound, naturalistic transparency mode, and a light and comfy fit, helping them live up to their intent as a “wear anywhere” solution. They provide some solid features, but skimp on battery life with just 5.5 hours per charge, and their noise canceling is just OK. Their oddly unresponsive touch controls and reliance on flimsy silicone sleeves further diminish their value, but they’re still Sony buds and could be worth nabbing on a good sale.
Montblanc MTB 03 for $395: These earbuds are priced out of reach for most buyers, but if you’ve got the cash, you’ll be rewarded with a luxury experience worthy of the brand. Montblanc has called in some heavy hitters from the audio industry to design and voice these buds. The result is a small, comfortable, and quite flashy-looking pair of wireless earbuds that sound really impressive.
As a general rule, you should avoid earbuds that don’t support the Bluetooth 5.0 standard (or higher), or don’t offer at least five hours of battery life—more like six these days. Batteries in wireless headphones degrade over time, so the better your battery life is at first, the more tolerable it will be in two to three years.

Apple AirPods (Previous or Current Gen) for $119–$170: These headphones do some things well, we just don’t like them all that much. (Read our latest review.) They get OK battery life, come in a compact case, and work well for calls, but they don’t fit all ears well, and since they don’t have ear tips or wings, you’re out of luck if they’re loose. The priciest model adds noise canceling, which works about as well as you’d expect for a pair that doesn’t offer a proper seal. Want clear music, good noise canceling, and advanced features made for iPhones for less than the AirPods Pro 3? Get the AirPods Pro Gen 2, which sometimes cost more (and sometimes less) but are legitimately great.
Beats Solo Buds for $70: These are lackluster in virtually every possible way, especially when it comes to features for the money. Their best traits are their micro-size and big battery, but that’s about it. It’s odd, because we like other headphones from the brand, but these just don’t keep pace. The best we can say is they are cheap.
We’ve seen this category go by many names: true wireless earbuds, truly wireless earbuds, completely wireless earbuds, fully wireless earbuds, wirefree earbuds, etc. These days, if a pair of earbuds connects to your phone/computer via Bluetooth and has no cord that connects the left bud to the right, we just call them wireless. Wireless sets typically come with two popcorn-sized buds, each with a battery inside, and a charging cradle that carries extra battery power and keeps them safe when you’re not wearing ’em. Some wireless earbuds have a cable or neckband that connects the two buds together, usually found on workout buds from brands like Shokz.
Ridding yourself of all cords can feel liberating, but these do come with issues, such as limited battery life (don’t buy any with less than five hours), confusing controls, and reliance on a charging case. They’re also easier to lose than traditional earbuds, and replacing one bud can be expensive. That said, this is one of the most innovative categories in tech, offering a flurry of new features from heart rate monitors to OTC hearing aid functionality, with more added in each new generation. These days features like noise canceling and transparency mode are standard, while the burgeoning open-ear category offers a more natural way to keep aware of your surrounding.
We test headphones and earbuds the way that we live. We take them to the gym, wear them around offices, travel with them, and generally try to use them as we anticipate potential buyers will use them. If a pair advertises dust or water resistance, we test that. We drop-test cases and test cables, charging times, and battery life, and we note everything we find exceptional to our readers.

While we do not typically use a set playlist of music to test each pair, we aim to test acoustic, rock, hip hop, pop, country, and a variety of other genres with every pair of headphones, ensuring offer a good perspective on sound signature across genres and volumes. For noise reduction, we test the headphones in real-world environments and note our findings. When possible, we attempt to have headphones worn by a variety of people with different head and ear shapes, to ensure we’re thinking about the widest audience possible.
Over the past two years, I have noticed that when I teach students about any issue in the U.S. or around the world, they express noticeable apathy and disinterest. When our current president was elected, I asked a Latina student how she felt, and she said she likes him because he will “teach her how to make money.” When I pushed back on this and brought up undocumented immigrants, she responded by saying, “Hold up. I’m a citizen, that’s not my problem.”
Recently, a similar problem came up with another student who is Black; he responded to our discussion on genocide by saying he “doesn’t care” and “only wants to make money.”
I care deeply about my students. For me, the apathy and individualism I’m seeing from them are legitimate and concerning. In their eyes, the only things that make life easier are money and power. I feel for them, but what breaks my heart is that this money and power are not, and historically have never been, in the hands of people like my students. Historically, opportunities for marginalized folks have come from working together as a community to fight for the lives and resources we need.

But as of late, I don’t believe our schools are structured to facilitate meaningful opportunities for our students to organize and build community. I am grateful that I was trained to be a content expert in English Language Arts using the most recent research, such as grading for equity, culturally responsive teaching and universal design for learning (UDL). From a curricular standpoint, the practices each of these frameworks offers have helped me create some memorable moments of enduring understanding. Still, these extreme times necessitate more than thoughtful rubrics, scaffolded assignments and culturally representative instruction. I worry that no amount of revelatory critical theory will galvanize my students, most of whom are working-class, to see the value of intellectual rigor.
As the years go on, and our political climate becomes more polarized, I, too, am breaking down. I am increasingly focusing on myself just to survive. If this is my story, with the opportunities I’ve been given and the books I’ve read, then my students are definitely experiencing this tenfold. And on top of that, they come to school to shuffle around between classes, sit down at desks, and learn information that we tell them will free their minds, but then they leave and the conditions don’t change.
The traditional factory schooling model is no longer holding up, and I believe it will one day collapse under the weight of its own obsolescence. When that happens, how do we create an educational experience that centers empathy and galvanizes action? While I don’t necessarily have an answer to this question, I think it’s worth exploring some ideas.
Bringing in Community-Based Organizations
Community-based organizations that support students after school in learning how to organize should be empowered to come to the classroom and lead workshops regularly. The end goal should be students leaving the building on several guided field trips to demonstrate, protest and volunteer.
Advertisement
The challenge with this approach is that I believe it should be done weekly during school hours. If working-class students can’t organize or volunteer due to the innumerable responsibilities they face once they leave our school building, then the only time we have with them to get involved will be during school hours. Therefore, it is our responsibility to create opportunities for community engagement.
Organizing as Project-Based Learning
While project-based learning is an exceptional approach to producing work, what would it be like for students to organize? They pick an issue, and we teach them how to rally for that cause by canvassing, visiting people affected by it or conducting interviews. The goal here is to produce an organizing plan for a cause that interests them. The grade comes from the success of the process, but the work is geared toward addressing social issues in real ways and not just reading about them.
School-Wide Practices
What if, every year, students were expected to organize in some capacity and produce reflections that explicitly ask them to explain how their empathy has increased through their organizing? The only way I see schools continuing is if they are transformed into sites of resistance — thinking hubs for revolutionary action — that takes place during school hours. We cannot, under these current conditions, presume that our students have the time, energy and resources to think about anything we teach them once the bell rings for dismissal.
Teacher Preparation
Teacher education programs would have to be transformed so that, in addition to content mastery, we are trained on how to organize and teach organizing. If schools do not become sites of resistance, I don’t see a future in which our young people will think of school as anything other than a chore they must take on to survive in a world built to keep them feeling small. Unless we teach them their power through collective action, they will grow to facilitate the same dangers that led to their individualism.

I often think about Gil Scott-Heron’s words, “The revolution will not be televised.” When asked what this meant, he responded, “The revolution has to happen here,” pointing to his head. The most valuable learning happens when no one is watching.
Personally, one of my greatest achievements in life has been learning to love myself as I am. But it took years of reading books that explained to me how and why the world was set up to make me hate myself. I came out the other end feeling better about myself — all because of reading and writing. But at the end of the day, I am bound up in the same system of exploitation and poverty that makes my students focus exclusively on themselves. Books freed my mind, but they did not free me from my conditions.
Our ancestors taught us that the structures in place were not built for our most marginalized. As a result, they organized. They saw each other as the resources needed to be free, and more often than not, they did it outside the classroom.
I am increasingly disillusioned by the concept and reality of a classroom as a site of transgression, when the structure of school itself ensures that any transgression can only exist in the mind and not manifest in the real world. The only way to transgress within this schooling system is to create structured, meaningful opportunities to step outside the four walls of our classrooms. We cannot simply read about revolutionary action; we must become it.
The ills of social media are pretty well-known, and the impacts are so well-documented that Meta, YouTube, and TikTok are now facing a lawsuit for making their platforms addictive. Australia has already banned social media for teens under 16 years of age, and multiple other countries are considering similar restrictions. And let’s face it: social media can lead you into a doomscrolling spiral that is an utter waste of time and energy.
Enter Pankaj Tanwar, a developer who just created a Chrome extension that will make you scream at your computer in order to unblock social media sites. “A productivity tool that blocks social media websites and makes you say embarrassing things to unlock them,” says the extension’s description on Google’s web store. But screaming at your PC or Mac is not the whole solution.
This is pretty cool
ScreenshotNadeem Sarwar / DigitalTrends
First, you must hit the loudness threshold while screaming, “I am a loser.” Next, you must increase the tempo of your embarrassing scream to unlock the time for which a blocklisted site becomes accessible. Based on how desperately loud you are, you might unlock a few seconds or minutes worth of social media surfing time.
I tried. I failed.
The open-source tool is aimed at students, at-home workers, and basically any person with a computer who gets distracted quickly and ends up losing valuable time to mindless X or Instagram browsing. By default, the extension blocks X, Instagram, and Facebook. However, if you have other digital vices, ahem, you can simply add the URL and block those sites, too.
I desperately needed it
Nadeem Sarwar / DigitalTrends
Once you set up the extension, which also works well in other Chromium-based browsers such as ChatGPT Atlas, you will run into a full-screen blocker every time you try to visit the distracting sites. There’s even a visualizer where you can see the loudness levels of your screen, and a timer underneath that shows you the duration for which the sites will be unlocked.
This won’t be the first project of its kind. Rhys Kentish, a software engineer at a UK-based company, developed an app called Touch Grass that will require you to go out, literally touch grass, and click a snapshot as evidence to unlock distracting apps on your phone.

As far as the “Scream to Unlock” browser extension goes, well, I desperately needed a solution like this. I visit X and Reddit for research and news gathering, but often end up wasting too much time getting distracted by random posts and rabbit holes. Thankfully, the little honor that I have left stops me from shouting at my PC and waking up my cat.

Apple is keeping the entry level for iPhones at $599, according to Bloomberg‘s Mark Gurman. In the latest Power On report, Gurman said that the iPhone 17e is “due imminently” and will keep the same price as its predecessor.
Considering we’re about a year away from the iPhone 16e’s announcement, we’re due for a successor to Apple’s more affordable smartphone. According to Gurman, Apple upgraded the new budget-friendly iPhone with MagSafe charging and the A19 chip that’s seen in the iPhone 17 base model. The iPhone 17e will also get Apple’s latest in-house cellular and wireless chips, Gurman reported.
In our review of the iPhone 16e, we weren’t particularly sold because of its limited camera capabilities, particularly when compared to the iPhone 17‘s release a few months later. However, for the same $599 price, Apple’s iPhone 17e is getting a few notable upgrades and will compete with Google’s Pixel 10a. More specifically, Gurman expects Apple to target the emerging economies and enterprise demographics with the iPhone 17e. While Apple faces a lot more competition in overseas markets, iPhone sales have been experiencing a resurgence in China. Apple is even forecasting strong sales for iPhones across Asia, especially in China and India.
On January 26, 2026, an astronaut on the International Space Station looked earthward and captured a view of the Grand Canyon that few people have ever seen. A fresh layer of snow from a few days of flurries clings to the canyon’s rim, framing the huge abyss in stark white against the deep red-brown rock below. The Colorado Plateau looks like a flat canvas sprinkled with dust, while the canyon itself, carved out by the Colorado River over millions of years, plunges into darkness.
Sunlight floods in from the bottom right, throwing lengthy shadows up the canyon walls. These shadows occasionally play a devious trick on you. Flat plateaus might appear high and almost like mountain peaks because most people believe light enters from above. However, the snow on the higher land puts the record straight, telling your eye that the snowy pieces belong on the higher edges, not the valley level. The South Rim is roughly 7,000 feet tall, whereas the North Rim is much higher at 8,000 feet. And you can notice the contrast in the coating of white that remained after the storm passed.

Warmer air at ground level inside the canyon converted the same precipitation to rain. Phantom Ranch received only 0.06 inches, while the canyon’s margins were holding onto several inches of fresh fall. Winter averages are 58 inches on the South Rim and 142 on the North Rim, so a light dusting like this is not unusual. But from up high in orbit, the contrast is everything, as the snow highlights every twist and curve of the canyon margins, transforming a recognizable landmark into something like to a map of its own elevation lines.
The astronauts on Expedition 74 captured this photo with a Nikon Z9 at 400mm as part of routine Earth observation missions from the station. The files were processed at Johnson Space Center, trimmed, and contrast adjusted to bring out the details without getting too fancy. The archives contain two versions of the photograph, both of which are high enough resolution to show the road along Desert View Drive, which was briefly closed owing to ice during the flurry.
The Winter Olympic Games have begun, and once again the sport of curling is set to draw in scores of new converts.
Although dominated by Sweden, Canada, Switzerland, and Scotland, many eyes during the 2026 Winter Olympics will be on the team from host country Italy thanks to Stefania Constantini and Amos Mosaner, the reigning Olympic and world curling champions in mixed doubles.
Regardless of which country takes home the gold, the real attention during the Olympics this year might be on the cool gadgets curlers use. Somewhat similar to a game of shuffleboard played with brooms and stones, curling has seen some pretty interesting advances in the gear that’s used on the ice.
In addition to raw skill and strategy, here’s everything you need to know about the state of the sport.

Scottish Stones
Nearly every curling stone—the round rock that slides down the ice—comes from the same place: Ailsa Craig. The 99-hectare island site in the Firth of Clyde inlet on Scotland’s west coast is known for its granite, and by extension its ability to provide enough of it to outfit curlers the world over.
Each stone must weigh between 19.96 and 17.24 kilograms and is made from one of two varieties of Scottish granite, common green and blue hone. These two types are the most resistant to heat and humidity and to the cracks and condensation that can form thanks to the 28 meters of ice the stones slide on during competitions.
The stones used at the Olympics, as well as the World Championships, are produced by Kays of Scotland. Many curling stones also come from Canada Curling Stone. (The sport has seen a recent spike in popularity in Canada.) Both companies produce the stones using a meticulous process of grinding and polishing.
Broom Boom
In addition to the stones, the main tools necessary to curl are a broom and shoes—this is where advancements in gear really come to the fore. For one, there are scores of sensors and microchips that allow players to manage the power of their throws.

For another, there are new-and-improved brooms that allow sweepers to maximize their skills. More than anything, what curlers need to work a broom are dexterity, physicality, and coordination. But beyond that, good tools don’t hurt.
“Broom technology continues to be a major focus because the physical demands of the sport continue to evolve, and one of the biggest challenges is finding the right balance between weight, strength, and effective energy transfer,” says Dale Matchett, general manager at curling equipment company BalancePlus.
As with any kind of sporting equipment, quality depends on how much a team or player is willing to spend. Carbon fiber brooms are best for their combination of strength and lightness. Composite fiber works well for midrange players. Fiberglass is the cheapest option. The broom’s handle and bearing factor into its weight and sweeping efficiency.
NASA formally approves personal smartphones for government missions beginning with Crew-12
Artemis II will carry consumer phones alongside traditional spaceflight imaging equipment
Fast-tracked hardware approval marks a procedural shift inside NASA operations
NASA has confirmed its astronauts will now be allowed to carry personal smartphones on crewed missions, starting with Crew-12 and the delayed Artemis II flight.
Crew-12 is scheduled to travel to the International Space Station in mid-February 2026, while Artemis II is now expected to launch in March.
The policy change allows astronauts to use modern iPhone and Android devices during missions, marking a shift away from NASA’s long reliance on agency-supplied cameras.
Policy change expands crew access to personal hardware
NASA administrator Jared Isaacman said the decision was driven by a desire to give crews more flexible tools for documenting their experiences and sharing images and video with the public.
“We are giving our crews the tools to capture special moments for their families and share inspiring images and video with the world,” Isaacman wrote on X.
NASA leadership framed the move as more than cultural, and the agency had to fast-track the approval of modern consumer hardware for spaceflight.

They argue the same urgency will support future scientific research in orbit and on the lunar surface.

The swift adoption of capable hardware could matter more than strict adherence to legacy procedures.
“Just as important, we challenged long-standing processes and qualified modern hardware for spaceflight on an expedited timeline,” Isaacman added.

“That operational urgency will serve NASA well as we pursue the highest-value science and research in orbit and on the lunar surface.”
Until now, astronauts relied largely on Nikon DSLR cameras and GoPros, many of which were designed years ago – and while those devices remain capable, they lack the immediacy and versatility of modern smartphones.
Smartphones combine advanced sensors, image stabilization, ultra-wide lenses, and video features into a single device that astronauts already know how to use.

NASA believes that familiarity may allow crews to capture more spontaneous moments without interrupting scheduled mission tasks or relying on specialized equipment.
With smartphones available, future missions may generate far more informal imagery and video than previous expeditions.
The change raises the likelihood of more frequent updates from orbit and deep space, potentially making upcoming missions among the most thoroughly documented in NASA history.
However, the agency has not outlined specific limits on personal content creation, though mission safety rules still apply.

Smartphones have flown to space before, including on private SpaceX missions, so the concept is not entirely new, but what is different is NASA formally approving personal devices for flagship government missions.
While the agency describes this as “a small step in the right direction”, it reflects a willingness to reconsider conservative technology rules.
The long-term impact will depend on whether expedited qualification becomes standard practice or remains limited to low-risk hardware such as personal smartphones.
The Core Duo processor from Intel may not have been the first multi-core processor available to consumers, but it was arguably the one that brought it to the masses. Unfortunately, the first Core Duo chips were limited to 32-bit at a time when the industry was shifting toward 64-bit. The Core 2 Duo eventually filled this gap, and [dosdude1] recently completed an upgrade to a Macbook Pro that he had always wanted to do by replacing the Core Duo processor it had originally with a Core 2 Duo from a dead motherboard.
The upgrade does require a bit more tooling than many of us may have access too, but the process isn’t completely out of reach, and centers around desoldering the donor processor and making sure the new motherboard gets heated appropriately when removing the old chip and installing the new one. These motherboards had an issue of moisture ingress which adds a pre-heating step that had been the cause of [dosdude1]’s failures in previous attempts. But with the new chip cleaned up, prepared with solder balls, and placed on the new motherboard it was ready to solder into its new home.
Earlier this year Donut Lab caused quite the furore when they unveiled what they claimed was the world’s first production-ready solid state battery, featuring some pretty stellar specifications. Since then many experts and enthusiasts in the battery space have raised concerns that this claimed battery may not be real, or even possible at all. After seeing the battery demonstrated at CES’26 and having his own concerns, [Ziroth] decided to do some investigating on what part of the stated claims actually hold up when subjected to known science.
On paper, the Donut Lab battery sounds amazing: full charge in less than 10 minutes, 400 Wh/kg energy density, 100,000 charge cycles, extremely safe and low cost. Basically it ticks every single box on a battery wish list, yet the problem is that this is all based on Donut’s own claims. Even aside from the concerns also raised in the video about the company itself, pinning down what internal chemistry and configuration would enable this feature set proves to be basically impossible.
In this summary of research done on Donut’s claimed battery as well as current battery research, a number of options were considered, including carbon nanotube-based super capacitors. Yet although this features 418 Wh/kg capacity, this pertains only to the basic material, not the entire battery which would hit something closer to 50 Wh/kg.
Other options include surface-redox sodium-ion chemistry with titanium oxide. This too would allow for fast charging and high endurance, but Donut has already come out to state that their battery is not capacitor-based and uses no lithium, so that gets shot down too.

Combined with the ‘cheap’ and ‘scalable’ claims this effectively shoots down any potential battery chemistry and architecture. Barring some amazing breakthrough this thus raises many red flags, especially when you consider Donut Lab’s major promises for investors that should make any reasonable person feel skittish about pouring money into the venture.
Sadly, it seems that this one too will not be the battery breakthrough that we’re all waiting for. Even new chemistries like sodium-ion arestruggling to make much of inroads, although lithium-titanate shows real promise. Albeit it not with amazing power density increases that would make it better than plain lithium-ion for portable applications.
The Heat Pass Block first appeared in Samsung’s 2nm Exynos 2600, reportedly delivering a 16 percent improvement in thermal resistance. It’s a copper-based layer built directly onto the processor die, providing a direct pathway for heat to dissipate before it can radiate through surrounding components. Read Entire Article Source link
