Ren Zhengfei, the founder of Huawei Technologies, said that the US forced Huawei to build its own technology. In other words, the US ban did that, as the company did not really have many options following a series of those bans.

Huawei founder believes the US forced Huawei to build its own technology

The company’s founder attended the ICPC (International Collegiate Programming Content) coding competition for university students, where he said that. He also talked with students about Huawei, technology in general, future goals, and a number of other topics.

At one point during the event, Zhengfei actually said that he believes Huawei can learn from the receptive culture of the US. He believes that it can make both Huawei and China advance in science and technology.

These were his exact words: “The US has set an example for all countries and companies worldwide on being open. If a country is closed off, it will fall behind”.

As many of you know at this point, the US sanctions landed in 2019, as security concerns were quoted. A number of additional roadblocks were set after that, though. Huawei is still blocked off from accessing tools to make chips and various other equipment.

Those bans forced Huawei to be self-sufficient

Huawei was forced to be self-sufficient, and it seemingly benefited the company in a way. Zhengfei said the following: “American technologies and tools are very good… [but] Huawei cannot use them; we had no choice but to create our tools. Open innovation and utilizing the advanced achievements of others is the true way forward for an enterprise”.

On top of everything, Huawei’s founder also highlighted the importance of AI. He said that artificial intelligence is becoming unstoppable. He said that if Huawei uses it in the right way, it could achieve a lot of success moving forward.

Huawei is expected to announce its 5nm processor made in collaboration with SMIC soon. That Kirin chip will be first used in the upcoming Huawei Mate 70 series.

Scientists have discovered a technique whereby light can be bent around corners, inspired by the way clouds scatter sunlight. This type of light-bending could lead to advances in medical imaging, electronics cooling and even nuclear reactor design.

Daniele Faccio at the University of Glasgow, UK, and his colleagues say they are shocked this type of light scattering wasn’t noticed before. It works on the same basis as clouds, snow and other white materials that absorb light: once photons hit the surface of such a material, they are scattered in all directions, barely penetrating at all and getting reflected out the way they came. For instance, when sunlight hits a tall cumulonimbus cloud, it bounces off the top, making this part of the cloud appear bright white. But so little light reaches the bottom of the cloud that this part appears grey – despite being made up of the same water droplets.

“The light bounces around and sort of tries to get in, and it’s bouncing off all the molecules and the defects,” says Faccio. “And eventually what happens is it just gets reflected back because it can’t get in. This is this scattering.”

To replicate this process, the team 3D printed objects from opaque white material while leaving thin tunnels of clear resin within. When light is shone at the material, it travels into these tunnels and is scattered – just as light is on snow or clouds. However, instead of scattering randomly in every direction until they are evenly dispersed, the photons are directed to return to the resin tunnel by the opaque material. The team put this to use, creating a range of objects that steer light in an organised way.

These 3D-printed objects are functionally similar to fibre optic cables, which route light along their length, but they operate on fundamentally different principles. Fibre optic cables steer light by infinitely reflecting internally. When photons attempt to leave a cable’s inner core of plastic or glass, they hit another material with a lower refractive index and are reflected back inside. In this way, light can be carried for kilometres at a time, even around bends.

The researchers say their material boosts light transmission by more than two orders of magnitude compared with solid blocks without the same clear tunnels, and also allows it to be directed around curves. This is much less efficient than fibre optic, and will therefore struggle to achieve the great distances that it does, but it is also very simple and cheap.

This method of light-bending could make use of existing tunnels of translucent material, such as tendons and fluid in the spinal column, to provide new ways to carry out medical imaging. Faccio says the exact same principle also works to direct heat and neutrons, and could therefore also find use in a range of engineering applications such as cooling systems and nuclear reactors.

“It wasn’t obvious that this would work at all. We were shocked,” says Faccio, who believes the phenomenon could easily have been discovered decades or even centuries ago. “It’s not like we’ve created or found some really niche, weird equation with some weird properties.”

Wireless headphones have become the go-to choice for so many people, and it’s easy to see why. They offer the freedom to move without tangled cables holding you back, and modern Bluetooth connections are more reliable than ever. On top of that, many wireless headphones deliver higher-quality sound than you’d expect, with impressive features like adaptive ANC (active noise cancelation) to block out distractions. Many wireless headphones now offer better battery life, too, giving you more uninterrupted playback whether you’re commuting, working out, or just kicking back with your favorite tunes.

Of course, some wireless headphones stand out from the rest, which is why Engadget has tested and reviewed the most popular options to help you find the perfect pair. Our picks are based on a mix of essential features like sound quality, ANC performance, comfort, and handy extras like companion apps for customization. Whether you’re after premium sound or a budget-friendly option, there’s a pair of wireless headphones for everyone.

How to choose the best wireless headphones for you

When it comes to shopping for a good pair of wireless headphones, the first thing you’ll need to decide on is wear style. Do you prefer on-ear or over-ear headphones? For the purposes of our buyer’s guide, we focus on the over-ear style as that’s what most noise-canceling headphones are nowadays. Sure, you can find on-ear models with ANC, but over-ear designs are much more effective at blocking sound. Speaking of noise cancellation, you’ll want to determine early on if you even want that. If you frequently crank up the beats in noisy environments, you’ll want to not only make sure it’s there, but also make sure it’s good, preferably with adaptive ANC. If you plan to use your new headphones in quieter spaces, skipping ANC can save you some money.

The next area to consider is features. We recommend trying to get the most bang for your buck, but as you’re shopping around you should determine which items are must-haves and what you can live without. And don’t take basic things like automatic pausing and Bluetooth multipoint connectivity for granted, as not all companies include them. We also suggest reading reviews to see how well a company’s more advanced features work. This will help you decide if those are something you’re willing to (likely) pay extra for. Keep an eye on better battery life estimates to avoid disappointment, as some manufacturers promise more hours than real-world testing delivers. And don’t be easily swayed by lofty promises about call quality without verifying them.

Sound can be subjective, so we recommend trying before you buy if at all possible. We understand this isn’t easy at a time when we’re doing most of our shopping online. But trying on a set of headphones and listening to them for a few minutes can save you from an expensive case of buyer’s remorse. We also recommend paying attention to things like Spatial Audio, Dolby Atmos, 360 Reality Audio and other immersive formats. Not all headphones support them, so you’ll want to make sure a perspective pair does if that sort of thing excites you. If you plan to use your headphones for other media besides music, checking for latency is also a must — some delay can impact playback for things like movies or games, even if most true wireless headphones now offer minimal lag.

How we test over-ear headphones

The primary way we test wireless headphones is to wear them as much as possible. We prefer to do this over a one- to two-week period, but sometimes embargoes don’t allow it. During this time, we listen to a mix of music and podcasts, while also using the earbuds to take both voice and video calls. Since battery life for headphones can be 30 hours or more, we drain the battery with looping music and the volume set at a comfortable level (usually around 75 percent). Due to the longer battery estimates, we’ll typically power the headphones off several times and leave them during a review. This simulates real-world use and keeps us from having to constantly monitor the process for over 24 straight hours.

To judge the best Bluetooth headphones, we focus on higher-quality audio by listening to a variety of genres and paying close attention to how each style sounds. We also test at both low and high volumes to check for consistency in the tuning. To assess the quality of phone calls, we’ll record audio samples with the headphones’ microphones as well as have third parties call us.

When it comes to features, we do a thorough review of companion apps, testing each feature as we work through the software. Any holdovers from previous models are double checked for improvements or regression. If the headphones we’re testing are an updated version of a previous model, we’ll spend time getting reacquainted with the older set. Ditto for the closest competition for each new set of headphones that we review.

Read our full Sony WH-1000XM5 review

Sony’s 1000X line has been our top pick for best wireless headphone for a long time now. Until another company can pack in as many high-quality features as Sony, and do so with a mix of excellent sound quality and effective ANC, the crown is safe. With the WH-1000XM5, Sony redesigned its flagship headphones, making them way more comfortable to wear for long periods of time. This is an important factor to consider when purchasing over-ear headphones. We also noticed in our tests that the company made noticeable improvements to the active noise cancellation, thanks to a separate V1 chip in addition to the QN1 that was inside the M4. There are now eight total ANC mics as well – the previous model only had four. This all combines to better block background noise and high frequencies, including human voices.

The 1000XM5 still has all of the features that typically make Sony’s top-of-the-line headphones showstoppers. That includes 30-hour battery life and crisp, clear sound with balanced tuning and punchy bass. A combo of touch controls and physical buttons give you on-board access to music, calls and noise modes without reaching for your phone. Speak-to-Chat automatically pauses audio when you begin talking, and like previous Sony headphones, the M5 can change noise modes based on your activity or location. Plus, this pair of headphones offers better call quality than most of the competition. The only real downside is that they’re $50 more than the WH-1000XM4 at full price ($400).

Pros

• Supreme comfort
• Great sound
• Powerful ANC
• 30-hour battery life

Cons

• More expensive than the M4
• Occasional audio issues on macOS

Read our full Bowers & Wilkins Px7 S2e review

An upgraded version of the Px7 S2, the Px7 S2e’s changes are mostly in the sound department. Bowers & Wilkins updated the digital signal processing (DSP) engine for improved performance when streaming music. The changes it introduced include support for up to 24-bit high-resolution streaming from compatible services. The company says it also re-tuned the acoustics for “unmatched detail, dynamics and spaciousness,” which is the more noticeable tweak compared to the previous model. Those promises hold true, too: the Px7 S2e are at the top of our test unit pile in terms of overall sound quality, just like the Px7 S2 has been since their introduction.

Bowers & Wilkins kept the rest of what was so great about the Px7 S2 as well. Reliable physical controls don’t lead to any frustration when you use them and the ANC performance is good enough to block out a lot of distractions. Factor in the refined design and overall comfort, and you’ve got a great pair of headphones that rival the best. The Px7 S2e still doesn’t have a lot of the more advanced features that Sony offers, but they sound so good you might not even notice.

Read our full review of the Bose QuietComfort Ultra

Bose’s unique take on spatial audio may be the headline feature on its QuietComfort Ultra Headphones, but the company didn’t overlook ANC on this model (Make no mistake — Sony takes the crown here for best ANC, but this Bose model is a close second.) Described as “the quietest quiet” available on any of its headphones yet, the ANC here is noticeably better than the Bose 700 and iconic QuietComfort Headphones. This is due in part to microphone enhancements that also improve call quality. The changes are especially apparent when dealing with the hard-to-combat frequency range of people talking. The company also offers presets that mix ANC, transparency mode and its spatial Immersive Audio, allowing you to quickly switch the sound to match your surroundings. And if that wasn’t enough, the touch controls make these over-ear headphones a breeze to use — so you get good noise cancelation, good sound and extra convenience bundled in this package.

While the spatial sound feature is a bit of a mixed bag, the stock tuning on the QuietComfort Ultra Headphones is still good – even before you switch on Immersive Audio. Bose has generally lagged the competition in terms of sonic prowess, but these over-ear headphones show that gap is narrowing. There’s a dash more bass to enhance a default sound profile that’s warmer, clearer and more inviting than previous Bose models, resulting in good sound overall. When Immersive Audio hits, it’s amazing and the audio quality is truly remarkable. But, the company is relying on signal processing rather than specially crafted content so the results vary.

Pros

• Excellent ANC
• Improved audio
• Clearer transparency mode
• Comfy

Cons

• Expensive
• Immersive Audio is inconsistent
• No USB-C audio

Back at CES 2022, Panasonic announced the EAH-A800: a new set of active noise canceling headphones under the iconic Technics brand. While most of the features are what you see on any number of wireless headphones, one figure stood out. The company says you can expect up to 50 hours of battery life on the A800, and that’s with active noise cancellation enabled. While we haven’t put them through the full review analysis, I have already tested them on a long flight. The ANC is impressive and they’re comfortable enough to avoid becoming a burden after several hours or many long listening sessions. Sound quality is also quite good (there’s LDAC support, too) and there are enough features here to justify the premium price tag.

Pros

• 50-hour battery life with ANC turned on
• Comfortable design
• Good sound quality

Noise cancellation: Yes | Multipoint: Yes | Battery life: 28 hours | Weight: 0.75 pounds | Water resistance: None

While Master & Dynamic is known for its design prowess, the company’s over-ear headphones were due for a refresh. With the MW75 that debuted in June, the company opted for a look that takes cues from its MG20 gaming headphones and mixes them with a combo of aluminum, leather and tempered glass. The company’s trademark sound quality returns with multiple ANC modes and ambient sound options for a range of situations. At $599, the high-end looks don’t come cheap, but if you’re looking for something beyond the pure plastic fashion of most headphones, M&D has you covered.

Other wireless headphones we tested

AirPods Max

Apple’s AirPods Max are premium, well-designed over-ear headphones that incorporate all of the best features you find on standard AirPods: solid noise cancelation, spatial audio and easy Siri access. However, their $550 starting price makes them almost prohibitively expensive, even for Apple users. There are better options available at lower prices, but if you can pick up the AirPods Max at a steep discount, they might be worthwhile for the biggest Apple fans among us.

Dyson On-Trac

The On-Trac headphones have an almost infinitely customizable design, and that’s what’s most unique about them. The sound profile offers some nice detail, but lacks dynamic range overall. ANC is average at best and there aren’t any advanced features that will make your life easier. Well, except for the hearing health monitor which is actually handy. All told, that’s not a lot in a set of $500 headphones.

Sonos Ace

The Sonos Ace is an excellent debut for the company’s first headphones. The combination of refined design, great sound quality and home theater tricks creates a unique formula. However, ANC performance is just okay and key functionality is still in the works for many users.

Sony ULT Wear

If most headphones don’t have the level of bass you desire, the ULT Wear is an option to consider. The low-end thump isn’t for everyone, but there are also plenty of handy features and a refined look to make the $200 set more compelling than many in this price range.

Sony WH-CH720N

While the WH-CH720N are a great affordable option, we prefer the Audio-Technica in the budget category. Sony’s cans are lightweight with good sound quality, but ANC struggles at times and they’re made with a lot of plastic.

Beats Studio Pro

The Studio Pro lacks basic features like automatic pausing, and multipoint connectivity is only available on Android. Moreover, they’re not very comfortable for people with larger heads. Overall sound quality is improved, though, and voice performance on calls is well above average.

Bose QuietComfort Ultra headphones

Bose’s latest flagship model has a lot to offer, but its trademark Immersive Audio feature can be inconsistent across different types of music. There’s still world-class ANC, excellent comfort and a clearer transparency mode, but for the price, the non-Ultra model is a better choice right now.

Master & Dynamic MH40 (2nd gen)

The MH40 are a great set of headphones if you favor crisp, clear and natural sound that isn’t overly tuned. This pair showcases the company’s affinity for leather and metal too, but limited customization and short battery life for non-ANC cans kept this set from making the cut.

Bowers & Wilkins Px8

The company’s trademark pristine sound is on display here, but the Px8 are more expensive and not nearly as comfortable as the Px7 S2.

Wireless headphones FAQs

How can you tell the quality of wireless headphones?

I typically look at three factors: design, sound quality and features. In terms of design, I’m usually looking to see if the build quality of the headphones feels cheap and plasticky. Plenty of companies use plastic, but they can do so in a way that doesn’t look or feel like budget models. For sound quality, I want to hear a nice, even tuning where highs, mids and lows are all well represented. No overly boomy bass or scooped out mids. I also want good clarity where you can pick up fine details and an open, immersive soundstage. Features is typically a distant third, but if a company doesn’t cover basic functionality (automatic pausing, transparency mode, multipoint Bluetooth, etc.) it can be an indication of overall quality.

How do I choose the best quality wireless headphones?

“Best” can be pretty subjective, but I always recommend going to a place where you can listen to the headphones you’re thinking about buying before you commit. Sometimes this isn’t possible, so you’ll want to check return policies. I also recommend doing some research to determine what your priorities are in a new set. Are you an audiophile who wants the best sound quality? Is powerful active noise cancellation (ANC) the most important? Would you rather have conveniences like automatic pausing?

Which brand has the best wireless headphones?

Sony consistently tops our list with its 1000X line. This is mostly due to the combination of sound quality, ANC performance and the truckload of features these headphones pack in. I’ll be the first to tell you that there are better sounding options and other companies, like Bose, offer more effective noise cancellation. But when you add everything up, no one comes close to the full slate of tools Sony puts in its premium headphone line.

Do expensive wireless headphones sound better?

Exorbitant price tags don’t mean better audio quality. Bowers & Wilkins’ headphones are on the high end for wireless noise-canceling models and they sound amazing. However, Audio-Technica’s M50xBT2 is much more affordable and doesn’t have ANC, but these headphones have a warm, natural sound profile that I find very inviting. At the end of the day, it will come down to personal preference, but you don’t need to spend a lot to find great headphones.

KOR Protocol, a Web3 infrastructure for creators featuring a range of AI-powered tools and interactive applications, has added artists Disclosure, Dixon and Imogen Heap join Deadmau5 and Richie Hawtin as advisers.

The KOR Protocol, whose initial developer is owned by Web3 gaming firm Animoca Brands, aims to improve how how intellectual property from music to other interactive art is managed, distributed, and monetized within artist communities.

British recording artist and Grammy award-winner Imogen Heap, electronic music icons deadmau5,
Richie Hawtin, and Disclosure, and masters of multimedia experiences Dixon, whose Transmoderna art collective is known for its immersive live-shows, will help oversee the direction of the protocol and advise on supporting artists, musicians, filmmakers, and developers in protecting their creations and engaging directly with their audiences.

Global recorded music revenues rose 10.2% in 2023 to $28.6 billion led by online streaming services, marking the ninth year of consecutive growth for the music industry. Yet despite the undeniable profits
made by global megastars like Taylor Swift or Ed Sheeran, the majority of artists struggle to make a
living from their music alone.

According to a survey by Xposure Music, just 11% of independent artists earn income solely through their music. A major issue is the low payout rates, which can be as little as $0.004 to $0.008 per stream. Additionally, streaming platforms like Spotify and Apple Music keep a significant portion of the revenue, with record labels also taking hefty cuts, leaving artists with a small portion of the pie.

KOR Protocol addresses this imbalance, changing how intellectual property is managed, distributed, and monetized, enabling artists and creators to receive fair pay for their work and engage directly with their fans and communities. Offering a unique infrastructure for creators with a range of AI-powered tools and applications, artists can easily create interactive experiences and release into new products that resonate with global fan communities. Adding such highly regarded world-renowned artists as advisors underscores KOR Protocol’s commitment to empowering creators with next-generation technology—and the best possible direction from leaders in their respective fields.

Heap is passionate about creating a decentralized database where songs act as services, giving direct access to all their details. Through her various initiatives, including Creative Passport and Auracles and collaborations with platforms such as KOR, she aims to open new opportunities and revenue streams for music makers, driving innovation in the industry. Electronic music icons deadmau5 and Richie Hawtin, known for their forward-thinking approaches to music and tech, have also previously explored the intersection of music, digital IP, and blockchain, cementing their advisory roles to help drive innovative content creation and fan engagement strategies.

Disclosure’s connection to remix culture will further help develop KOR’s vision of an ecosystem where artists can co-create and remix content without traditional limitations, reinforcing the platform’s mission to make the creation and management of music IP transparent, collaborative, and fair, and Dixon and his collective Transmoderna will be a leading guide on pushing the boundaries of immersive multimedia experiences, exploring the possibilities that arise from merging electronic music with transmedia art.

Inder Phull, creator of KOR Protocol, said in a statement, “This visionary team of artists are not only leaders in their fields but are passionate about creating new immersive experiences and fair compensation for artists. Under their expert guidance, KOR Protocol can provide the next generation of entertainment ecosystems for creators and fans alike.”

In addition to these artists, Ben Turner, co-founder of the International Music Summit and Association for Electronic Music, and Dean Wilson, CEO of Seven20 and manager of Deadmau5, will join the protocol as partners and advisors. Their extensive experience in the music and entertainment industries will help guide KOR Protocol’s development as a comprehensive platform for managing, distributing, and monetizing intellectual property.

Pixelynx, the first developer behind KOR Protocol was acquired by Animoca Brands, leaders in the Web3 and entertainment space. From IP registration, licensing, and royalty tracking to decentralized interactive content creation, KOR Protocol enables artists, developers, and fans to collaborate seamlessly shifting the paradigm of traditional IP management.
