How do you stand out as a new tech company when the dominant players have huge budgets, thousands of employees and decades of product R&D? That is Nothing’s challenge, and its first product, a pair of true wireless earbuds, makes a pitch for a simplified kind of tech, designed to stand out from the likes of Apple AirPods, Samsung Galaxy Buds and their myriad clones.

Design appears to be very important to Nothing, which has already published several blog posts dedicated to its philosophy and direction — and that’s before the company even launched anything. This is the result. The $100 Ear 1 buds feature active noise cancellation, touch controls, a wireless charging case and a particularly eye-catching see-through design, coming to the US mid-August.

This transparency — a design choice that I love — seemingly resonates with Nothing’s mission to make technology less obvious and more seamless. It makes a statement.

Engadget, Mat Smith

This styling extends to the charging case, which reminds me a lot of Apple’s old wired headphones that used to come packaged with iPhones. They also came in a half-transparent case. Nothing’s Ear 1 case is predictably more complex. The see-through shell has three indented bubbles that keep the buds in place. There’s a red dot both on the right headphone and its socket inside the charger.

Like most wireless earbuds, tiny magnets pull the buds into place, but this time they’re visible. Nothing apparently had to find suppliers to make sure its transparent design would work. The company needed glue that was either invisible or at least more aesthetically pleasing, and according to a spokesperson, these tiny, polished magnets were apparently hard to come by.

So yes, the Ear 1 is all about attention to detail. The case shuts with a satisfying thud, and the snippets of text across the hardware and even the companion app pay homage to retro technology — or perhaps computer interfaces on Alien. These feel like a tribute to see-through tech we’ve seen in the decades past. You might immediately think of those see-through Game Boys from the early ‘90s, but also Apple’s early 2000s eMac all-in-one PC, with transparent casing laid onto white and metal.

Surprisingly, the price is reasonable. These are sub-$100 earbuds, which would put them up against Beats’ latest truly wireless buds and make them cheaper than Apple’s entry-level AirPods. What do you get at this price, though?

While I haven’t had enough time to fully scrutinize sound quality, the Ear 1s sound decent, although there’s no spatial audio functionality which isn’t great for new headphones in 2021. Teenage Engineering, which worked with Nothing on these buds, was responsible for tuning the headphones. The sound is generally clear, but seems to lean toward the mid-range frequencies rather than treble and bass, though you can adjust the equalizer to ramp up either of those levels.

At this price, they predictably don’t stack up against more expensive earbuds like Sony’s WF-1000XM4 ANC buds or Apple's AirPods Pro. But, perhaps thanks to the silicone tips, they definitely sound better than the original AirPods. The Ear 1s are plenty loud, too.

Each bud weighs under five grams, making them lighter than those more expensive options, while still packing active noise cancellation — something Google’s similarly priced Pixel Buds A lack. After several months using the AirPods Pro, Nothing’s debut earbuds definitely feel more comfortable to me.

Despite the lightness, Nothing claims you should get four hours of listening with ANC on, and up to 5.7 hours (340 minutes) with ANC off. The case — which is wider but slimmer than most charging cases — can add up to a total of 34 hours of listening. There’s some fast-charge tech, too: After 10 minutes in the case you can get about another hour of listening time.

The case can be charged through USB-C or Qi wireless charging — another notable addition at this price. The earbuds are also rated IPX4 for sweat and dust resistance, so they can handle workouts that don’t involve too much rain or perspiration. There are touch controls on both buds, and you can slide your finger up and down the stem for volume control, while a single tap will play/pause and a triple tap will skip a track.

Nothing’s buds are compatible with both Android and iOS devices, and you don’t gain or lose anything depending on which mobile OS you prefer. That is, apart from fast pairing, which is coming to Android devices but isn’t yet enabled at the time of writing.

As much as I love the aesthetics of the Ear 1, my first impressions of these earbuds weren’t great. When trying to connect to my iPhone, pairing was a struggle. Once the buds were eventually connected to my phone, Nothing’s headphone app said that the fully charged case was empty — or not even detect it at all. Similar chaos ensued when I tried to shift pairing to my PC and Android phone. Bluetooth connections can be messy — this just seemed like a messier than it should be. The case itself seems to have its own Bluetooth profile, separate from the buds. That might be what makes pairing the headphones so frustrating.

Nothing’s companion app not only offers a different way to switch between noise cancellation modes, but also a way to reassign touch controls on the Ear 1. It’s a refreshing, uncomplicated app. Having wrestled with other headphone apps from Sony and the rest, though some audiophiles might find it a little restrictive.

There are four equalizer presets: balanced, more treble, more bass and voice. However, you can’t adjust the equalizer manually. The Ear 1 does offer a little more flexibility with noise cancellation with light and maximum settings you don’t often see on earbuds.

The Ear 1 has three high-definition mics for voice calls, with Nothing’s own “clear voice technology,” which utilizes algorithms that apparently help isolate and amplify your voice on calls. It should also help cut out wind noise.

I had a mixed experience with the Ear 1 for phone and video calls. With my handset, the three built-in mics coped with the noise of coffee shops and busy streets fine — in fact the people I talked to said my voice sounded particularly clear. When pairing with my Mac, however, audio quality seemed notably worse than other wireless buds and even the MacBook’s built-in mic.

The Ear 1 buds are an impressive debut device. Nothing’s first product launch is all about selling you on its cool — the company offered a limited run of hardware on StockX that seemed plainly targeted at Hypebeasts and early adopters. The design is compelling, and even the specifications are impressive at this price point. Nothing needs to improve on connectivity hiccups and sound quality if it wants to be mentioned in the same tier as Apple, Samsung and Sony, but it’s a bold start.

As part of new restrictions on sexual content, Google is banning what it calls "compensated sexual relationships (i.e. sugar dating)," from its Android app store, starting September 1st, 2021. Google’s wording on its inappropriate content policy isn’t live yet, but on Google Play, even now, there are plenty of sugar-daddy-style apps that fit this description, including Elite Millionaire Singles, SeekingArrangement and Spoil. (Many of these apps are already unavailable on iOS.)

This is unlikely to stop the existence of these apps and networks, however, but as is often the case with removed games and apps in the past, devout sugar daddies, mommies and their fans will be able to either sideload the app (without secure Google-approved updates) or use web apps on Chrome or their web browser of choice.

Nura's latest wireless earbuds sound truly unique

The Nuratrue brings automatic audio personalization to true wireless headphones.

James Trew / Engadget

Nura might be a relatively new name in headphones, but the personalized-audio specialist is already revealing its third model: the Nuratrue. They’re wireless earbuds you can tune precisely to your listening profile.

The ability to create personal hearing profiles is Nura’s whole thing, but according to James Trew, Nura’s is the simplest and most reliable. Just pop the buds in your ears, walk through the profile creation process in the app and the headphones do everything else. James really did hear the difference. Whereas “unpersonalized” buds may be technically balanced on a graph, when your hearing isn’t perfect, Nura can fill in the gaps. Continue reading.

If you have an older Amazon Kindle with 3G internet, take note that you may not be able to wirelessly access and download new content anymore starting in December. As The Verge reports, Amazon has sent out emails to owners with old Kindles, telling them that previous-generation devices will lose internet access after mobile operators transition from 2G and 3G networks to 4G and 5G.

The e-commerce giant listed the particular devices that will be affected by the switch in its FAQ page. It noted that the first- and second-generation Kindles, as well as the Kindle DX, won't be able to connect to the internet at all since they don't have WiFi connectivity to fall back on. The other devices in the list are the Kindle Keyboard (3rd Generation), Kindle Touch (4th Generation), Kindle Paperwhite (5th, 6th and 7th Generation), Kindle Voyage (7th Generation) and Kindle Oasis (8th Generation), all of which have WiFi connection.

You'll still be able to access your books on an older device and can do wired transfers if you want, though. And if you have a newer 4G or WiFi-only Kindle, you won't be affected at all. In its email, Amazon included a code customers can use to get $50 off a new Kindle Paperwhite or Oasis, along with $15 in eBook credits. You may want to check your inbox to see if you got the company's notice in case you've been looking to upgrade anyway.

Bang & Olufsen is no stranger to the true wireless game. The company has a number of wire-free models under its belt at this point, but there has been on glaring omission over the years: active noise cancellation (ANC). Today, B&O remedied the issue with its new Beoplay EQ earbuds. The pricey audio accessory not only offers the ability to reduce ambient ruckus, but earbuds also feature solid battery life, wireless charging and more. The only potential deal breaker is the price: $399 (£349/€399). 

Similar to flagship earbuds from the likes of Sony and others, Bang & Olufsen's "Adaptive Active Noise Cancellation" setup on the Beoplay EQ is powered by a dedicated ANC chip. This means the Bluetooth chip isn't pulling double duty. That component combines with a set of four microphones to continuously monitor your surroundings and automatically adjust ANC levels as needed. That's the "adaptive" bit. Two additional microphones are equipped with "retune noise reduction technology" that B&O says results in "crystal clear" calls. Mileage varies greatly on claims of voice quality when it comes to true wireless earbuds, so that description is definitely something that will need proper testing. When it comes to sound, the company's app offers a feature called Beosonic that allows you to fine-tune things as you see it. 

Bang & Olufsen

In terms of battery life, Bang & Olufsen says you can expect 6.5 hours on the earbuds themselves with two additional charges in the case. That case supports wireless charging and in true B&O fashion, it's made out of aluminum. The company included a quick-charge feature that gives you two hours of listening time in 20 minutes. To help you find the best fit, there are four sizes of silicone tips and one pair of Comply foam tips in the box. Lastly, the Beoplay EQ is IP54 certified, so they should withstand dust and water splashes just fine. That's enough to keep the earbuds working through your sweaty workouts. 

The Beoplay EQ will be available in most of the world August 19th in black and gold color options. The earbuds actually go on sale today in China and Japan, but only in black. Gold will be available in those countries next month.  

A new robot known as the Dominator has set a Guinness World Record for placing 100,000 dominos in just over 24 hours. Created by YouTuber and former NASA engineer Mark Rober, the Dominator is the result of more than five years of work. Rober had help from two freshmen from Stanford University and a Bay Area software engineer in creating the googly-eyed robot. The group programmed more than 14,000 lines of code, and outfitted it with components like omnidirectional wheels and 3D-printed funnels to create what Rober says is a “friendly robot that’s super good at only one thing: setting up a butt-ton of dominos really, really fast.”

Up against professional domino artist Lily Hevesh, the Dominator used its ability to lay down 300 tiles all at once to work about 10 times faster than a human. It took the robot about two hours to put down over 9,000 dominos.

While the Dominator is the face of the project, a lot of its efficiency comes from a separate sorting mechanism that consists of a Kuka robotic arm and almost three miles of Hot Wheels tracks. A series of conveyor belts ferry the dominions by color before the Kuka arm deposits them in the appropriate chute. When the Dominator visits the station for a refill, the lower platform slides away, instantly loading its 3D-printed funnels with all the dominos it needs to lay down 300 at once. In this way, downtime is kept at a minimum.

To put its final achievement in context, it would take a team of seven skilled domino builders about a full week to make the Super Mario Bros.-like mural the Dominator needed a little more than a day to complete.

There's still half a year to go before you start seeing Google Play's new safety section, which will show you an Android app's privacy information, in listings within the store. Google announced the upcoming feature that's similar to the Apple App Store's nutrition labels back in May. In a new post on the Android Developer blog, though, Google has given us a glimpse of what that section may look like. 

Within a listing, you will see a summary from the developer on what kind of data an app collects, so you can make a decision whether to install it or not. You'll also see safety details the developer chooses to highlight, such as whether an app encrypts your data, whether it's suitable for children and families and whether it's been independently validated against a global security standard.

Google

Further, you can tap the summary to see more details about the type of data an app collects and how it's used. It can show you whether an app collects location and contact data, personal information such as name and email address, as well as financial information. The section can also tell you whether the app uses your data for its features, for personalization or for other purposes. In addition, it can let you know whether you can opt out of getting your data collected or if giving an app access to your information really is necessary to be able to use it.

Google says the details might still change before the feature goes live, but all developers are required to provide a privacy policy for their apps and must provide accurate information for the safety section. Developers can start declaring privacy information in October and have until April 2022 to do so, but you'll start seeing the section pop up on Google Play sometime within the first quarter of next year. 

Snapchat is updating its in-app map to help users keep track of places they’ve visited, and where they may want to go next. An update rolling out today adds a new “Places” section to the map, with educated sections for recommendations, locations you’ve visited and “favorites” to remember.

The idea is similar to Foursquare (the original check-in based iteration), except “checking in” in this case consists of tagging a specific location in a Snap. Places you’ve tagged are automatically saved in your “visited” tab, but you can also manually add establishments to your “favorites” list. Interestingly, Snap is also using the new feature to generate recommendations. The “popular” section of the map will surface a list of personalized suggestions based on places you’ve been and what’s popular in your area.

Though the Snap Map has been around for years the company has been working to make it more useful — and more visible — within the app. The company gave the feature more prominent placement in a redesign last year, and plans to add Map Layers, a feature that allows third-parties like Ticketmaster to incorporate events and other content directly into the map.

Nura might be a relatively new name in headphones, but the personalized-audio specialist is already revealing its third model: the Nuratrue. As the name suggests, the latest member of the family is a true wireless set (and the company’s first model without a wired option). As you might expect, Nura’s flagship automatic hearing test (for sound tailored to your hearing) is here, along with many other features the company has already made synonymous with its brand. But with a smaller form factor, are compromises inevitable?

The Nuratrue ($199/£199) is a simplified version of the Nuraphone over-ears and the Nuraloop wireless (but tethered) sports buds. As mentioned, the audio customization feature is present, as is the “ambient” mode — which Nura calls “social mode.” There’s even Active Noise Cancelling and “immersion” mode, which simulates the feeling of being at a live event. The last two are a little simplified compared to their bigger siblings, though.

The original Nuraphone’s immersion mode delivers tactile bass with transducers creating a sensation of volume and presence similar to being in front of a large speaker. On the Nuratrue, it feels more like a bass “boost” feature you might find on an equalizer. Active Noise Cancellation on the Nuratrue works pretty well, but is tied to the social mode feature which means they are activated as a pair. This makes no real functional difference, but something to bear in mind. Battery life is estimated at six hours here and seems accurate, which can be extended to around 24 hours via the charging case.

James Trew / Engadget

If you were a fan of the Nuraloop, you might have expected the Nuratrue to be broadly the same, minus the connecting cable. But you’d be wrong. The new buds barely share any visual or physical DNA with their cabled sibling. Instead the Nuratrue has a much larger, circular body which sorta looks like you’re wearing “plugs,” but in the middle of your ear. This extra size might sound like a negative, but it makes them easier to touch (for controls) and likely helps keep them wirelessly connected to each other.

That “touchability” is important, as, like most TWS earphones, it’s how you’ll interact with them — in particular, for activating things like immersion or social mode. (ANC can only be toggled via the app it seems, and as mentioned disables social mode with it). In my testing with them the touch was more responsive than most other TWS headphones I’ve tried, especially the tricky double-tap which I find often requires a few attempts to register correctly. As with all Nura headphones you can easily assign different tasks to either side for both single and double taps, making it easy to have the controls you use the most at hand (or finger, technically).

Obviously, the main selling point here is Nura’s proprietary audio personalization. The ability to create personal hearing profiles is kinda Nura’s whole thing. It’s a feature you see on other brands, too, but Nura’s is the simplest and, in my experience, the most reliable. Mostly, because it doesn’t involve any subjectivity. Just pop the buds in your ears, walk through the profile creation process in the app and the headphones do everything else. Most other similar “tests” require you to tell the app how well/if you heard something. As someone who’s done more than their fair share of hearing tests, I always start imagining phantom sounds and worry that affects my results.

James Trew / Engadget

Cool features are… cool and all, but you probably just want to know how they sound? I guess the smart answer is, that will depend on your ears. The slightly more helpful answer is that, for me, the personalized audio definitely puts the Nuratrue above most of the TWS headphones I have tried. It’s not that they have better bass or polished treble, although those would be fair statements, it’s more that they feel neutral and balanced.

Whereas “unpersonalized” buds may be technically balanced on a graph, I know that my hearing isn’t perfect and thus might be slightly worse at certain frequencies. With Nura’s personalized tuning, it’s hard to know what frequency curve I am getting, or even if that’s what my hearing really “needs” but what I do know is that I like it!

Now, I guess I should also say that I am never sure just how effective Nura’s hearing test really is. The company claims that it uses otoacoustic emissions to determine the characteristics of your hearing. The same test is sometimes used to determine cochlear hearing loss in newborns. That said, every time I’ve been to an audiologist (which is more times than I would like) I have asked them about using OAE tests for headphones, and all of them have been skeptical it can be done on hardware at this price. When I asked Nura about this, they gave the following reply:

“The OAE signal produced by a person's ears is indeed faint - much like the signals of GPS satellites are faint by the time they reach the Earth's surface. That's why GPS-enabled devices of 20-15 years ago were much larger, less accurate, and took longer to acquire a signal than today's smartphones or even smartwatches. Similar advances in signal processing have enabled the huge improvement in GPS device performance and the quick & reliable measurements of OAEs in devices as small as Nuratrue.”

In short, the company claims that advances in technology have allowed for the test to be practical in small, consumer devices.

James Trew / Engadget

Back to the physical design briefly. It might not be for everyone, but it feels very much in keeping with Nura’s apparent mission to do things a little bit differently. I’ve never really found a TWS design that I think has fully cracked it (although Jabra’s Elite 75t comes close?), and that’s true here. But, as mentioned earlier, I do appreciate the large surface area for controlling playback or activating/deactivating the extra features. Extended wear remains comfortable, and the fit works well for my ears.

If I had one minor gripe, it’d be the maximum volume. It’s not low. In fact, for me, it’s more or less ideal for comfortable, extended use. It’s just that, “comfortable” is the maximum, so when a song comes on that I really love and I decide that, heck, I can crank this one up a bit before going back to normal levels… there’s nowhere to go. Again, this might not be an issue for you. I’ll be the first to admit I probably haven’t done my ears any favors over the years, but it was something I noticed fairly quickly in my time with the Nuratrue.

In an ocean of true wireless headphones, it’s hard to stand out. But Nura’s personalized audio is certainly enough to do just that. Of all the “customizable” headphones I’ve tried, Nura’s are still the ones to beat. And with the Nuratrue priced at least $80 cheaper than the flagship models from Sony, Sennheiser and Bose, that’s just another easy way for the company to garner attention.

The Nuratrue is available starting today.

The curse of buying new tech at the wrong time will get us all. In the last year, I’ve seen fellow Engadget employees buy a Nintendo Switch just before the OLED model broke cover, take the plunge with the iPhone SE just before the iPhone 12 mini was unveiled and make several more shopping missteps. Now, I might have done the same.

I picked up Sony’s vlogging camera, the ZV-1, earlier this month. I was looking for an agile video setup for the occasional time I have to record footage at Engadget without a skilled member of our video team. It’s very easy to make it work, with great face tracking capabilities and even a product showcase mode that helps me really show off whatever gadget I’m handling and I was happy with it. 

For a couple of weeks.

Sony

Then I heard the rumors that Sony was about to expand its vlogging camera family, and my heart sank. Here it is, then. The ZV E-10, a new vlogging camera that fuses the tiny frame of the ZV-1 with interchangeable lenses. 

The two major improvements seem to be a larger 24-megapixel sensor and an interchangeable mirrorless mount. The latter means you can use one of the 60-plus E-mount lenses, while that larger sensor should offer improved light sensitivity and a shallower depth of field. The ZV-E10 will launch by the end of August and will cost $700 for the body or $800 in a bundle with one of Sony's power zoom lens. The price is roughly level with how much I paid for the ZV-1 earlier this month. It’s probably too late to ask for a refund, right?

Cassie, a bipedal robot that's all legs, has successfully ran five kilometers without having a tether and on a single charge. The machine serves as the basis for Agility Robotics' delivery robot Digit, as TechCrunch notes, though you may also remember it for "blindly" navigating a set of stairs. Oregon State University engineers were able to train Cassie in a simulator to give it the capability to go up and down a flight of stairs without the use of cameras or LIDAR. Now, engineers from the same team were able to train Cassie to run using a deep reinforcement learning algorithm.

According to the team, Cassie teaching itself using the technique gave it the capability to stay upright without a tether by shifting its balance while running. The robot had to learn to make infinite subtle adjustments to be able to accomplish the feat. Yesh Godse, an undergrad from the OSU Dynamic Robotics Laboratory, explained: "Deep reinforcement learning is a powerful method in AI that opens up skills like running, skipping and walking up and down stairs."

The team first tested Cassie's capability by having it run on turn for five kilometers, which it finished with a time of 43 minutes and 49 seconds. Cassie finished its run across the OSU campus in 53 minutes, 3 seconds — it took a bit longer, because it included six-and-a-half minutes of dealing with technical issues. The robot fell once due to a computer overheating and then again after it executed a turn too quickly. Jeremy Dao, another team member from the lab, though, said they were able to "reach the limits of the hardware and show what it can do." The work the team does will help expand the understanding of legged locomotion and could help make bipedal robots become more common in the future.
