I have tried the Huawei FreeClip 2, headphones with a still strange shape but surprising comfort

by

I’ve been using the Huawei FreeClip 2 for a couple of weeks. I put them on out of work obligation, but since then they have spent more time in my ears than I thought they would. That says quite a bit about these headphones. But, as almost always in life, there are asterisks. Huawei FreeClip 2 technical sheet HUAWEI FREECLIP 2 Earphone dimensions and weight 25.4 × 26.7 × 18.8mm 5.1g per earbud DIMENSIONS AND WEIGHT CHARGING CASE 50.0 × 49.6 × 25.0mm 37.8g sound 10.8mm driver NOISE CANCELLATION ANC Cancellation on calls with 3-microphone systems ‘Crystal-clear calls’ system Open-ear transparency mode microphones 3 Clear Voice battery 60 mAh per earbud 537 mAh in charging case USB-C charging 5V 1.5 A Wireless charging up to 3W Theoretical autonomy Up to 9 hours on a single charge Up to 38 hours with the case charged connectivity Bluetooth 6.0 Dual connection Quick pairing on Huawei with EMUI 10.0 or higher compatibility Android 8.0 or higher / iOS 13 or higher (to use the Huawei Audio Connect app) Standard Bluetooth connection without advanced features if the app is not used design Open-ear headset with C-shaped bridge design (arc that surrounds the ear) Bridge material: silicone + shape memory alloy Resistance IP57 (headphones) and IP54 (case) price 199 euros HUAWEI FreeClip 2 Wireless Bluetooth Headphones, Open Earbuds, All Day Comfort, Open-Ear Adaptive Listening, up to 38h Autonomy, iOS and Android, 42 Month Warranty, Black The price could vary. We earn commission from these links Design with personality and that requires personality The design, officially “C cross-bridge design” and unofficially “two pairs of cherries”they no longer feel like as risky a bet as they did in their first version. That first generation It made me ask a legitimate question.: Who is going to want to wear spheres hanging from a cable over their ear? This is how they will see you with them. Image: Xataka. Two and a half years later, after a wave of imitators of the format, it seems that the market has responded: people do want this. I personally still have my reservations: I don’t go through life hiding, but Yes, I like to go unnoticed, and with these headphones in my ears it is complicated. There is some look from someone who wonders if that is an earphone, a modern hearing aid, a piercing or what. Huawei has reduced the weight to 5.1 grams per earbud. The bridge that connects both parts uses liquid silicone with shape memory. And the tension is just right: they don’t press, they don’t slip. I have bent down to pick things up from the floor, I have run with them and I have spent long periods of time cleaning the house with them in my ears. They usually don’t move. But there is some ‘but’: Sometimes, for some reason (I guess we all have different ears), my left one would slip a little and I would have to adjust it. Are you going to wear a hood? Problem. Will you take off your sweatshirt? Problem. These helmets are not designed to stay there with that type of friction. Running with them is acceptable, but it is clearly not their ideal use, and in fact I did not feel like repeating the play. By the way, these headphones, like those of their first generation, They are exactly the same as each other, there is no left and right model.so it doesn’t matter how you put them on or how you store them in the case. That’s where the sound comes out to your ear. Image: Xataka. Open-ear comfort always sounded like an empty promise until now. These headphones fulfill it because they simply disappear. You really forget you’re wearing them. After hours with them I suddenly realized that they are still there. That’s how well they integrate, that’s how little they bother you. The sound, without any big fuss, it fulfills for the day to day, without further ado. The bass has presence thanks to a drivers 10.8 mm double diaphragm. They do not give the punch of closed headphones, but for an open design it seems acceptable to me. Voices over the phone remain clear, but the treble at high volumes sounds a bit sharp. With the ten-band equalizer you can do something. In short: they deliver, but no one expects miracles in detail and dynamics. The application to customize them and access some advanced features. Image: Xataka. What surprised me the most is controlling sound leakage at moderate volumes. Huawei incorporates a system that emits waves in inverted phase to cancel escaping audio. That is, the noise cancellation system, but towards the outside instead of inward. It works reasonably but not impressively. I listen to something with my wife and, if it is not at high volume, she assures me that she does not hear anything. I pass them on to her and confirm it. If I decide to increase the volume to around 80%, there is an obvious leak. I didn’t try the first FreeClipbut I remember seeing some complaints on this point. The problem has not disappeared but I think it has lessened. The battery is one of its strong points. Lasts up to nine hours of continuous real use. Seven or so most of the time. With the case you can chain charges up to about 38 hours in total. Very good figures for those who travel or spend the day working outside. Fast charging is another detail: ten minutes in the socket gives you three hours of autonomy. A unique appearance. Image: Xataka. The touch controls work on the cable that joins both parts. At first I didn’t understand why a natural gesture produced certain behaviors. Then I failed several attempts because I forgot where that wire was exactly. Afterwards you get used to it, but it is not a perfect system, it is not completely reliable because it requires a lot of precision. Swiping your finger on the … Read more

A cheese giant is slowly taking shape in Spain thanks to a key ally: Mercadona

by

The long list of Spanish companies that grow in the heat of Mercadona adds a new name: Entrepinaresa company dedicated to the production of cheeses and dairy products that started 40 years ago in Valladolid and today manages centers spread throughout Galicia, Castilla and Madrid, in addition to generating employment for something more than 1,500 people. Although the signature presume to be “the largest cheese manufacturer”since more than 20 years has a key alliance with Mercadona. And that is helping it expand. Why is it news? Because their 2024 accounts have just been released, a year during which Entrepinares managed to skyrocket both its turnover and its profits. The first section rose to the 665 million euros8% more than in 2023. As for the second, EBIDTA (earnings before taxes) reached 64 million, which represents an increase of 16%. Both indicators are partly explained by an increase in production: in 2024, 100 million kilos of cheese came out of the Entrepinares factories (8.3% more than in 2023) and around 35 million kilos of dairy products. In addition to being the main supplier of Mercadona cheeses, the company saw how it was reinforced its foreign activity, with exports to more than 50 countries. Is there more data? Yes. We know that the company dedicated 41 million to investments in search of greater efficiency, which raises the mobilization of resources for that purpose above the 140 million in the last four years. Thanks to this commitment, it has managed to gain a prominent place in the sector at a national level. In fact it leads the sectoral ranking of cheese manufacturers (at least based on turnover volume) prepared by elEconomista. Regarding staff and internal resources, the firm has more than 1,500 workers, collaborates stably with more than 700 farms and a large score of cooperatives and manages four production centers spread across Valladolid, Fuenlabrada, Villalba and Los Yébenes. Added to these are a logistics and packaging center in Valladolid and two other plants specialized in whey treatment located in Castrogonzalo (Zamora) and Vilalba (Lugo). Why is it important? Because of the data itself and its context. Entrepinares is not the only Mercadona supplier that has grown in recent years coinciding with the expansion of the Valencian chain, which has managed to strengthen its position in the market with a business share that It is already on its way to 30%. One of the clearest examples is that of the group Martinez Familywhich integrates several business lines and operates as a strategic supplier to Mercadona. It was recently revealed that the company will invest around 150 million euros between this and the next year to reinforce its Traditional Dishes facilities and keep up with Mercadona. Months before it had emerged that last year its billing increased by about 8% and its net profit 16%. Are there more cases? Yes. Another Mercadona supplier that has managed to grow is Ozturk Quebapa firm based in Toleado specialized in the production of kebabs and meat products that has been supplying the Juan Roig chain for years. Last year it invoiced around 63.8 million euros and this year it hopes to exceed 75. For now, in the first semester it reached 37.8 million. Its expansion is prior to the agreement with Juan Roig’s company and the firm exports to other nations, but Ozturk recognizes that “with Mercadona everything changes.” Mercadona’s leverage is also serving Sefood Group. Its subsidiary Leroy Processing Spain hoped in the spring to close this year with a turnover of 160 million euros30% more than last year. The company has been dedicated to the production of Japanese food for a few years and has managed to make Mercadona one of its main clients. The Roig chain also has among its suppliers: Profand and Panamar, Tarradellas House and Summer.

Drones revolutionized warfare in Ukraine, now they are going to do it all over the world with one final trick: changing shape

by

If something has become clear after these years of war in Ukraine, it is that drones are no longer a mere complement from the battlefield: they have become a such transformative technology like gunpowder or the Kalashnikov, and are entering a second, even more disruptive phase, driven by artificial intelligencethe miniaturization and the accelerated production. Their next landing is planetary. The second revolution. As we said, drones have gone from being tactical support to becoming a structural factor of modern warfare. Ukraine has shown that an inferior actor in means can degrade a great power with cheap swarms air, naval and land. At the same time, insurgencies, militias and states with few resources use the same logic to compensate for conventional disadvantages. The result, as we will see below, is a global diffusion of precision capabilities at low cost that reduces own risks, complicates defense and makes conflicts more accessible and resistant to resolution. War spine. The trajectory of drones goes from radio-controlled experiments in world wars to smart cruise missiles and platforms like the predator and the reaper in the “war on terror.” The recent turning point is Nagorno-Karabakhwhere an average country combined decoys and UCAVs with artillery to neutralize anti-aircraft defenses and dominate the air without powerful traditional aviation. Since then, the central lesson is that no need be a superpower: simply integrate drones, sensors and indirect fire intelligently to alter the tactical balance. Ukraine as a laboratory. In Ukraine, the drone design, testing and tuning cycle has been compressed to weeks. kyiv has scaled from imported platforms to its own industry that produces millions of unitscombining FPV, reconnaissance, long range and fiber optic guided systems to circumvent Russian electronic warfare. The proximity between workshops and front allows for rapid iterations on sensors, frequencies and flight profiles. Russia responds with mass production and specialized units like Rubikon. The front thus becomes an environment where each innovation is copied or counteracted in a very short time. Swarm globalization. The intensive use of drones has extended to conflicts with a lower media profile. In Africa, dozens of states and non-state actors have built-in armed UAV to internal wars, with markets dominated by exporters such as Türkiye and China. In Myanmar, rebels have converted commercial drones into a substitute for artilleryforcing army withdrawals. In Gaza, Hamas used them to blind Israeli sensors before raids. This shows that technology not only balances power relations, but also increases lethality and makes subsequent stabilization difficult. AI, ammunition and fire economy. The AI integration Drones transform the economy of combat: the cost per useful impact decreases and precision increases. Now there are kits software and hardware that allow existing platforms to locate, track and attack targets with limited human supervision. The practical effect is to reduce the need for classical artillery and increase the efficiency of fire, both on land as in sea. However, this does not eliminate the value of artillery or manned platforms, but rather shifts part of the fire load to systems more fungible and scalablewith clear implications for budgets and logistics. The new unmanned spectrum. And here comes one of the big changes, possibly the least expected. The drone family is expanding and transforming, changing shape and size: from nanodevices for close reconnaissance to enormous ships and underwater vehicles autonomous. The former allow discreet exploration in urban or closed environments, and the latter expand the presence on the surface and under the sea without embarking crews or assuming their risks. Between both extremes, ukrainian naval systems, Chinese XLUUV or AUV as the Ghost Shark redefine surveillance, anti-submarine warfare and area denial operations. The common pattern is to eliminate the need to protect lives on board, making it easier to accept high-risk missions and speed up production. A new generation of contractors. Companies like AndurilAuterion or Shield AI operate with startup logic: short development cycles, strong software integration and commitment to assuming own risk before winning large contracts. Some choose to control the entire chain (hardware and software), others to offer “operating systems” applicable to multiple platforms. This puts pressure on traditional, less agile contractors, and reconfigures the industrial ecosystemwith more mid-sized players competing in specific niches (loyal squires, swarms, mission software). The result is greater speed of innovation, but also more fragmentation of solutions. China, the US and the race. China part with advantage in commercial drones and transfers that leadership to the military fieldwhile investing very heavily in countermeasures after observing the performance of cheap drones in Ukraine. The proliferation of manufacturers of anti-drone systems and directed energy weapons indicates a strategic commitment to control both attack and defense. The United States, despite the accumulated experience, appears out of date in volume and in anti-swarm systems, with dispersed programs and irregular financing, which forces to emergency measures to accelerate purchases and use dual suppliers. This anticipates a long race in which quantity, cost and active defense weigh as much as the individual sophistication of each platform. Strategic limits. This point is often not taken into account. The destructive capacity of drones can lead to overestimating their strategic impact. From there what spectacular operations against high-value infrastructure do not always translate into lasting changes in the control of territory or in the political will of the adversary. Controllers like Radakin they underline that drones and algorithms do not replace the need for a coherent strategy or forces capable of occupying and holding ground. The temptation to build campaigns based on high-visibility specific hits can generate a dangerous gap between tactical success and strategic results. The era of eternal wars. All this breeding ground leads to a final scenario: by reducing costs and risks for those who prolong the combat, drones favor conflicts. no clear outcome. Statistics show fewer decisive victories and fewer peace agreements since the 1970s, while stagnant wars increase. In this context, drones provide continuous capacity for harm to actors who would otherwise be forced to negotiate or give in. The probable result is more long wars, distributed … Read more

We have centuries studying the different types of clouds. What tells us the shape and color of these atmospheric phenomena

by

The atmosphere of the earth hides about 12.9 billion liters of watermore or less. And a good part of that water is in huge clouds that we see fly over our heads as if nothing. These huge atmospheric objects captivate our imagination in childhood, but we often stop thinking about them during our day. Knowing them can help us pay attention to them. What is a cloud The clouds are essentially water, a lot of water. Steam -shaped water, small drops and Even small ice crystals that remain in suspension in the atmosphere. This water becomes visible when condensed, generating a contrast with the blue of the sky. The clouds circulate in the atmosphere dragged through the differences in pressure and the wind that they generate. They also move as a result of the land rotation itself, since the solid surface of the earth does not rotate in the same way as the atmosphere. The clouds can be of very different types that we classify according to certain conditions, such as the height to which they occur. For example, when the clouds are formed at surface height, we do not even usually refer to them as such, but as a fog. But the fog is still a type of cloud. How a cloud is formed The atmosphere keeps water vapor, small H2O molecules that are mixed with the other gases that make up the atmosphere. The amount of water that the atmosphere can store in the form of gas depends on factors such as temperature and pressure. There is a threshold from which the atmosphere Water “sat”and that is when this water can begin to accumulate. This accumulation is good when the amount of water increases or because atmospheric conditions make the threshold reduce, and implies that the molecules go from being a gas in suspension to form microscopic water drops. When these drops, still in suspension, accumulate, the clouds are formed. Types of clouds and characteristics The clouds are usually classified according to two fundamental characteristics: Your altitude in the atmosphere and its appearance. According to its altitude, three types of clouds are distinguished (with an additional case), groups that the State Meteorology Agency (Aemet) call of “high floor” (the highest altitude), of “middle floor” (intermediate altitude) and those of low floor (those of minor antura), to which we must add the clouds of vertical development. There are different terms with which referring to these clouds, for example we can speak sympleously of high, medium and low clouds. High floor clouds The high -floor clouds are those that are at heights between 5 and 13 kilometers on the ground, and include cirro, circoum and cirrostrates. Cirrus: According to Explain Aemetcirrus are clouds of the high floor, separate and “in the form of white and delicate filaments, or banks or narrow, white or almost white bands.” Cirrus. Piccolonamek, Commons. CIRCOUM: It is a thin layer of clouds, white and shadowless, “very small elements” in the form of grains or undulations. Circummers. King of Hearts. CIRROSTRATE: These clouds for their part acquire the appearance of a “cloudy veil”, also transparent and rather white, only that this type of clouds covers the sky, totally or partially, producing “halos.” Cirros and its characteristic halo. SeanMack Medium floor clouds The clouds of the middle floor are located at heights between two and seven kilometers, and can also be of various types: altocumulos, high, and nimbostratos. Altocúmulos: The altocumulus are already located at medium heights. It is a bank or cloud layer that can be white or gray. Its structure can varybeing formed by “tiles”, “rounded masses” or “rollers”, structures that, in turn, can be “partially fibrous or diffuse,” Explain Aemet. Altocumulos. Bidgee Altostrates: This layer of clouds usually has gray or bluish colors, it can also have a fibrous appearance, it is characterized by totally or partially covering the sky allowing to distinguish vaguely, but unlike cirrostrates, it does not produce halos. Altostrates. Famartin. Nimbostrates: These clouds form an already dark gray layer, with “appearance veiled by rainfall or snow precipitation”, rainfall that usually falls from it more or less continuously. Nimbostratos. Famartin. Low floor clouds The low floor clouds are those located at heights of up to two kilometers and can be of two types: strata and strata. Stratocumulous: Again clouds that can acquire a gray color, or, on other occasions, whitish with dark parts. Stratocumulous. DjClimber. Strata: Generally gray clouds, uniform base (relatively), which can produce drizzle. The halos in this cloud only occur when very low temperatures are reached. Strata. Couch-Scratching-Cats. Vertical Development Clouds Finally, vertical development clouds can also be of two types: clusters and cumulonimbos. Clusters: These are clouds that arise in isolation, dense and well -defined contours. These clouds develop vertically with the form of “protuberances”, “domes” or “towers.” Clusters. Piccolonamek. Cumulonimbos: Finally, the cumulonimbos are clouds that Aemet describes as “Amazacotadas and Dense”, of vertical development “in the form of a mountain or huge towers.” On his cusp, a top “smooth, fibrous or striated.” Cumulonimbos. NOAA/AOML/Hurricane Research Division. How much water is there in a cloud? The clouds are ethereal objects, “cotton” and with a density low enough to keep afloat at a certain height in the atmosphere. However, they are also huge, so the amount of water they can house is enormous. A few years ago, a group of researchers proposed answer the question How much water is in a cloud. The truth is that the answer can vary greatly since the volume of these atmospheric phenomena can be the most diverse. However, the team made an estimate based on a 0.5 grams of water per cubic meter of cloud. The team took as reference an average cluster, an cloud that would have a cubic shape and a kilometer long. The result: this imaginary cloud would contain about 500 tons of water. Larger clouds, of course, would be able to house an even greater amount of water.

The almost instantaneous load batteries and a shelf life close to eternity are taking shape. Thanks to quantum physics

by

Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge he has given us Modern Quantum Theory. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, quantum physics is present in much of modern technology. During the last five years several research groups, such as the PSL Research University (University of Recherche Paris Sciences et Lettres), which resides in Paris (France), or that of the University of Pisa, in Italy, have tried to use the basic principles of quantum mechanics to point A new generation of batteries. And the results are getting little by little. This is its starting point: they pursue to use overlap, entanglement and superabsorption to tear down the limitations that electrochemical batteries currently impose. The quantum storage of energy is an ideal that is increasingly closer The main difference between quantum batteries and conventional electrochemicals is that the latter depend on chemical reactions, while quantum devices seek to store energy in the quantum states of some particles, such as, for example, photons. It seems complicated, and it is, but the really important thing for users is that quantum batteries on paper can be loaded almost instantaneously, they will have a much higher energy density, and, in addition, their degradation will be minimal as the load cycles pass. Quantum batteries can store energy in a superposition of multiple energy states simultaneously It sounds wonderful. So much, in fact, that seems science fiction. However, it is very important that, as we have just seen, let’s not overlook that their principle of operation will be, if they finally come to fruition, very different from that of conventional electrochemical batteries. Existing theoretical proposals argue that quantum batteries They can store energy in an overlap of multiple energy states simultaneously, which should allow them to deliver a much greater energy density. In addition, your theory load will be much faster, even almost instantaneous, due to the collective quantum effects of the quantum units that make them up. The most amazing thing in this field is that the higher the capacity of the quantum battery, the faster it will load. It is an intuitive characteristic, it is true, but it is possible precisely thanks to the collective quantum effects I just talked about. However, this is not all. And it is that on paper the degradation that these batteries will experience during energy transfer will be minimal, so your useful life will be much greater than that of conventional batteries. Perhaps, even, almost eternal if we compare it with the longevity of the human being. So far all the work that researchers had carried out in this area had condensed in purely theoretical models, but this panorama has just changed. And it is that several scientists from the universities that I have mentioned in the second paragraph of this text have published an article very interesting in which they propose How to make a quantum battery. Your idea is to use superconductor circuits produced with materials that exhibit essentially zero resistance at low temperatures. They have not yet manufactured anything, so it is evident that the hardest work, the experimental, is still pending. But there is no doubt that this proposal invites us to tie the future of quantum batteries with reasonable optimism.

Celtics looked out of shape in Los Angeles and the Lakers passed them by

by

LaBron James celebrated his 21st. consecutive NBA All-Star designation with 20 points and 14 rebounds to lead the Los Angeles Lakers to a comfortable 117-96 victory over the Boston Celtics Thursday night, in a new edition of the greatest basketball rivalry. The first duel of the season between the two most winning and prestigious franchises in the NBA was actually an uneven game without much suspense in the Crypto Arena. The Lakers started quickly and built a considerable lead based on a magnificent first half, especially with solid defense and a barrage of three-pointers. A violent dunk by James was part of that first half totally dominated by the home team. Down by 19 points at halftime, The Celtics threatened with a reaction in the third period, approaching 12 points on multiple occasionsbut they never put real pressure. This time they did not present their best version, they lacked energy and shot very poorly from long distance (14 of 41 in triples). LeBron James extended his record of calls to the All-Star Games The Lakers (24-18) cooled down the game in the final period with consecutive mid-range baskets from a cool LeBron James, who hours before had added a little more history to his record by being named in the Western Conference starting five for the NBA All-Star Game along with Stephen Curry, Nikola Jokic, Kevin Durant and Shai Gilgeous-Alexander. James, 40, had already set the record for appearances in All-Star Games the previous season with his number 20 to surpass Kareem Abdul-Jabbar. Anthony Davis, star of the Lakers, manages to block the attempt of Kristaps Porzingis, of the Celtics. Los Angeles dominated the reigning NBA champion.Credit: Mark J. Terrill | AP Tatum and Brown were off for the Celtics Anthony Davis led Los Angeles with 24 points and Austin Reaves had 23. The Lakers made 15 of 35 3-point attempts, 11 of them in the first half. The lead was so big in the fourth quarter that even Bronny James came in to play a few minutes (0 points). For Boston (31-14), Kristaps Porzingis scored 22, but the star duo of Jayson Tatum and Jaylen Brown combined for just 33 points (12 of 31) before leaving the court early. The Lakers will now go on the road for six games and When they return to LA on February 6 they could have new faces on the roster. That day will be the deadline for trades in the NBA and the Lakers are expected to make moves to add at least one big man to help free Davis from center duties.
