Noise Buds F1 Review: Best TWS Under Rs. 1,200?


Noise Buds F1 hit the domestic market in May. These budget TWS earphones are claimed to be designed in India. They feature 11mm drivers and support Bluetooth 5.3 connectivity. The earbuds are rated IPX5 for water resistance. Along with the charging case, they are said to offer a total playback time of up to 50 hours. This impressive battery life is marketed as being paired with equally big sound, all within a suspiciously low budget. But do these budget earbuds truly live up to the claim?

Noise Buds F1 Design and Features: Light, Matte, Compact

  • Water and dust resistance – IPX5
  • Colours – Calm Beige, Carbon Black, Mint Green, True Purple

The Noise Buds F1 earphones come packed in a clamshell-style charging case with a matte finish on the top and bottom, while the sides are bordered with a glossy trim. The USB Type-C port is located on the right side, and at the front, there’s an LED indicator for pairing alerts or battery notifications. The case is light and compact, making it easy to carry around or slip into your pocket. Maybe don’t toss it in with keys or coins, as the matte areas are prone to scratches. You’ll likely need both hands to open the case. You could try with one, but like me, you might fail.

The touch sensors on each earbud are fairly accurate

 

Inside the case, the Noise Buds F1 earbuds are placed horizontally, both facing outward. They are rated IPX5 for water resistance. The inner side of the stem, which houses the charging connectors, has a glossy finish, while the other three sides feature the same matte texture as the case’s top. The earbuds come fitted with medium-sized silicone ear tips by default, which fit me best, relatively speaking. The box also includes small and large tip options, along with some literature, stickers, and a USB Type-A to USB Type-C cable.

The fit of the Noise Buds F1 is comfortable, all things (price range) considered. That said, after two to three hours of continuous use, I needed to take them off for a few minutes before I could use them again. These aren’t the best-fitting TWS earphones on the market, but they could make a decent workout companion, assuming your routine involves brisk walking rather than jumping jacks.

Noise Buds F1 Specifications: Few but Fruitful?

  • Driver – 11mm
  • Companion App – No
  • Gesture controls – Yes

The Noise Buds F1 offer Bluetooth 5.3 connectivity and support the SBC audio codec. These TWS earphones are equipped with 11mm drivers. There are glossy sections near the top of the stems where the fairly accurate touch sensors are located.

In the box, Noise packs two additional ear tip options

 

A single tap on the right earbud increases the volume, while a single tap on the left earbud decreases it. Double-tapping either earbud will pause or play a music track or video. Triple-pressing the left earbud takes you to the previous track, while the same action on the right skips to the next one. Pressing the right earbud four times activates the voice assistant on your paired device.

The Buds F1 also support a dedicated low-latency gaming mode. To activate it, press and hold either earbud for two seconds. A Megatron-like voice welcomes you with the battle cry “We Fight!” Repeating the same action exits the mode, this time with a “Game Over!” announcement.

The USB Type-C port is located on the right side

 

Admittedly, all these gestures can seem overwhelming at first. However, most of them are intuitive enough, and it won’t be long before you get used to them. Not “if,” because there’s no other option—the Noise Buds F1 lack a companion app to help manage these functions. Does that make them feel a bit lonely? Perhaps. But depending on your usage habits and needs, you may or may not feel the app’s absence.

Noise Buds F1 Performance and Battery Life: Promise Delivered

  • ANC – No
  • Battery Life – 8 hours (earbuds); 42 hours (case)
  • Fast Charging – Yes (claimed 150 minutes with 10 minutes charge)
  • Bluetooth – v5.3

Speaking of things that are absent—ANC. The pair of Noise Buds F1 headsets does not actively cancel noise. Passively? Some, not a significant amount. You will still be able to hear the TV in the next room, although it will be somewhat muffled. I do not mind, though, as I am aware of the friendship it offers my pockets instead. There will be compromises in this budget, and the lack of an app or active noise cancellation support is something I am happy to settle without.

During the review period, the earphones offered over 48 hours of total playback time

 

Now, back onto things that are present. Battery. The company does not reveal the size of the batteries it packs into the Noise Buds F1 earphones or their case. The earphones, together with the case, are claimed to last for up to 50 hours. It took me more than eight days to completely drain the battery, with an average of six hours of daily usage, resulting in over 48 hours of playback time. In simple words, they promise what they deliver, without much fuss.

The Noise Buds F1 earphones also offer a decent calling experience. Indoors, you are likely to face no problems with making clear calls. Once you step outside, even onto your windy terrace, the clarity dips significantly. But for a call-averse person like me, this is a non-issue.

Finally, let’s talk about the sound. For its price range, the soundstage that the Noise Buds F1 offers is decent—a big plus, because while it could be worse, there are hardly any better options at this range. The overall sound experience these earbuds deliver is boxy. The bass isn’t as punchy as what you might find in some other budget offerings. It’s passable at best for some, even if it felt squarely adequate to me. That said, the sound is relatively balanced, with mids and highs that are pretty stable. From Chaar Diwaari’s “Thehra” to Franz Ferdinand’s “Take Me Out,” you get a smooth and clear audio experience. Your favourite tracks may always sound like it is coming from the next room, but at least they are clear, not muddled. However, once you crank the volume up to 80 percent or higher, distortion becomes quite noticeable.

noise buds f1 gadgets360 review inline6 Noise Buds F1

The gesture controls on the earphones are mostly intuitive

 

The gaming mode on the Noise Buds F1 performs well. There’s little to no lag, and in games like Call of Duty: Mobile, sounds such as footsteps or gunshots come through clearly and distinctly. At this price point, they’re a solid option for casual gamers.

Noise Buds F1: Verdict

At Rs. 1,099, you’re obviously not getting a concert-like experience or anything close to a cinematic ambience with the Noise Buds F1. But if you’re anything like me and dread stepping out of the house without a headset, these are for you. Even if they don’t satisfy the audiophile in you, they’ll keep your brain busy enough to ignore the traffic or the crowd around you. And they last forever, if forever was almost nine days! A whole work week can pass you by, but a single full charge of these earphones will stay with you. Despite the lack of a companion app, they can be your trusty companion, especially if you’re on a shoestring budget.

Although if ANC is among your non-negotiables, these are not for you. You can instead check out the Noise Buds N1 Pro (Review), which offers a decent ANC performance at the given budget. They will cost you slightly more than the Buds F1, as they are currently retailing at Rs. 1,499. At Rs 1,799, you can also try the Redmi Buds 5C (Review), for effective ANC as well as app support.

Astronomers Discover 3I/ATLAS, Largest Interstellar Comet Yet Detected


Astronomers have discovered the third interstellar comet to pass through our solar system. Named 3I/ATLAS (initially A11pl3Z), it was first spotted July 1 by the ATLAS telescope in Chile and confirmed the same day. Pre-discovery images show it in the sky as far back as mid-June. The object is racing toward the inner system at roughly 150,000 miles per hour on a near-straight trajectory, too fast for the Sun to capture. Estimates suggest its nucleus may be 10–20 km across. Now inside Jupiter’s orbit, 3I/ATLAS will swing closest to the Sun in October and should remain observable into late 2025.

Discovery and Classification

According to NASA, in early July the ATLAS survey telescope in Chile spotted a faint moving object first called A11pl3Z, and the IAU’s Minor Planet Center confirmed the next day that it was an interstellar visitor. The object was officially named 3I/ATLAS and noted as likely the largest interstellar body yet detected. At first it appeared to be an ordinary near-Earth asteroid, but precise orbit measurements showed it speeding at ~150,000 mph – far too fast for the Sun to capture. Astronomers estimate 3I/ATLAS spans roughly 10–20 km across. Signs of cometary activity – a faint coma and short tail – have emerged, earning it the additional comet designation C/2025 N1 (ATLAS).

Studying a Pristine Comet

3I/ATLAS was spotted well before its closest approach, giving astronomers time to prepare detailed observations. It will pass within about 1.4 AU of the Sun in late October. Importantly, researchers can study it while it is still a pristine frozen relic before solar heating alters it. As Pamela Gay notes, discovering the object on its inbound leg leaves “ample time” to analyze its trajectory. Astronomers are now racing to obtain spectra and images – as Chris Lintott warns, the comet will be “baked” by sunlight as it nears perihelion.

Determining its composition and activity is considered “a rare chance” to learn how planets form in other star systems. With new facilities like the Vera C. Rubin Observatory coming online, researchers expect more such visitors in the years ahead. 3I/ATLAS offers a rare chance to study material from another star system.

NASA’s New Horizons Proves Deep-Space Navigation via Stellar Parallax



NASA’s New Horizons spacecraft carried out an unprecedented deep-space star navigation test while 438 million miles from Earth. Using its long-range camera in April 2020, it captured images of Proxima Centauri and Wolf 359, which appeared slightly shifted in the sky compared to Earth’s view – a striking demonstration of stellar parallax. It was the first-ever demonstration of deep-space stellar navigation. By comparing these images to Earth-based observations and a 3D star chart, scientists calculated New Horizons’ position to within about 4.1 million miles, only about 26 inches across the United States.

Stellar Parallax Test

According to the paper describing the results, accepted for publication in The Astronomical Journal, New Horizons’ camera imaged Proxima Centauri (4.2 light-years away) and Wolf 359 (7.86 light-years) on April 23, 2020. From the spacecraft’s distant vantage point, the two stars appear in different positions than seen from Earth – the essence of stellar parallax. By comparing those images with Earth-based data and a three-dimensional map of nearby stars, the team worked out the probe’s location to within about 4.1 million miles.

As lead author Tod Lauer explained, “Taking simultaneous Earth/Spacecraft images we hoped would make the concept of stellar parallaxes instantly and vividly clear”. He added, “It’s one thing to know something, but another to say ‘Hey, look! This really works!’”.

New Horizons and Future Missions

New Horizons, the fifth spacecraft to leave Earth and reach interstellar space, flew past Pluto and its moon Charon in 2015, sending home the first close-up images of those distant icy worlds. Now on an extended mission, the probe is studying the heliosphere.

New Horizons’ principal investigator Alan Stern called the parallax test “a pioneering interstellar navigation demonstration” that shows a spacecraft can use onboard cameras “to find its way among the stars”, in a statement. He also noted it “could be highly useful for future deep space missions in the far reaches of the Solar System and in interstellar space”

AI Designs Ocean Gliders Inspired by Sea Creatures to Boost Underwater Research Efficiency


Marine animals like fish and seals have long inspired ocean engineers due to their fluid, energy-efficient movements. Now, researchers are turning to these sea animals to create a new class of underwater gliders that requires very little energy, according to a team led by researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and the University of Wisconsin-Madison. They used artificial intelligence to design forms that slide through the water with less resistance, making long-term ocean exploration more efficient. These gliders, fabricated via 3D printing, promise better data collection on currents, salt levels, and climate impacts.

AI-Powered 3D Designs Create Energy-Efficient Underwater Gliders Inspired by Marine Life Forms

As per a study published on the arXiv preprint server, the team used machine learning to create and simulate numerous novel 3D glider shapes. By comparing traditional models—like submarines and sharks—with digitally altered versions, their algorithm learnt how different designs behaved at various “angles-of-attack.” A neural network then evaluated the lift-to-drag ratio of each shape, identifying those most likely to glide efficiently through water. These shapes were then fabricated using lightweight materials that minimised energy use.

In tests, two AI-generated prototypes—one shaped like a two-winged plane and the other like a four-finned flatfish—were built and tested both in wind tunnels and underwater. Key hardware was integrated with the gliders, including buoyancy control by a pump and a mass shifter to move the angle during displacements. The new gliders, with better shapes and lift-to-drag ratios, could travel farther on less power than traditional torpedo-shaped types.

The team added that what they are doing not only makes new types of designs possible but also reduces design times and cuts the cost since it doesn’t require physical prototyping. “This high degree of shape diversity hasn’t been investigated before,” Peter Yichen Chen, an MIT postdoc and co-lead author on the project, mentioned. He also noted that their AI pipeline allows testing forms that would be “very taxing” for humans to manually design.

The future plans are to produce slimmer and more manoeuvrable gliders and to improve the AI system with more configurable options. Intelligent bioinspired vehicles like these, the researchers say, will be essential in studying dynamic ocean environments that are changing quickly with the intensifying demands of industrial activity, ultimately offering more flexible and efficient ways for us to explore Earth’s last frontier.

Hubble Observations Give Forgotten Globular Cluster Its Moment to Shine


A striking new image captured by NASA’s Hubble Space Telescope has shed light on an underexplored gatekeeper of our galactic neighbours’ achievements and tragedies. Adorned with multi-hued stars, the spherical cluster glitters amid the expanse of stars in our Milky Way galaxy. This type of globular cluster is a very dense grouping of stars — about the same mass as 100,000 suns — that orbit all around the centre of their galaxy. Stars in a cluster are typically roughly the same age, as they formed from the same collapsing gas cloud. In this new view, stars show up in temperatures indicated in red and blue colours: red for colder and blue for hotter stars.

Hubble Maps Forgotten Star Cluster ESO 591-12 to Uncover Milky Way’s Ancient Stellar Secrets

As per a report from NASA’s Hubble team, ESO 591-12 was imaged during the Hubble Missing Globular Clusters Survey—an initiative targeting 34 Milky Way globular clusters that had never been observed by the space telescope. The aim is to construct a comprehensive database of the ages, distances, and stellar populations of all the galaxy’s known globular clusters and star formations. However, it has always been tough for telescopes on Earth to pick out individual stars in these densely populated regions, so Hubble’s high resolution has done much to finally be able to track the movements of stars to unlock their histories and formation.

The ESO 591-12 data are part of an ongoing study to improve knowledge of the formation and evolution of globular clusters in the galaxy’s bulge and halo. These star clusters are cosmic fossils that have preserved cosmic conditions from the primordial universe. Their work helps build a fuller narrative of the evolution of the Milky Way and how it has changed over billions of years.

This new image is a further example of how advanced space-based observing facilities are helping astronomers to excavate the contents of the dark and dusty skeleton cloaking the Milky Way and sculpt a better understanding of not only the universe’s evolution but also that of our cosmic home.
Each one tells part of the astronomical story, and Hubble is digging out new chapters to enrich the tale, such as probing data for clusters as much as ESO 591-12, which have been mostly neglected until now. This finding adds to our knowledge of the early universe by shining a spotlight on something that was in plain sight.

Very Massive Stars Blow Away Outer Layers in Powerful Winds Before Black Hole Collapse

Very Massive Stars Blow Away Outer Layers in Powerful Winds Before Black Hole Collapse


New research indicates that the most monstrously huge stars — those more than 100 times as massive as the sun — shed at least 20 times more matter before they collapse than previously thought to do so as they cool off to become black holes. These stars blow off a significant portion of their outer layers in quite powerful stellar winds over the brief but intense course of their lives, leaving behind low masses at the end. One benefit of this extreme mass loss is that it can account for observed strangeness in stars such as those in the Tarantula Nebula, providing new information on stellar evolution, black hole formation, and sources of gravitational waves.

Hurricane-like Stellar Winds Explain Extreme Mass Loss in Universe’s Most Massive Stars

As per a report from Space.com, researchers used sophisticated models and observations to learn that very massive stars give off winds so powerful they act more like hurricanes than gentle solar breezes. Their results agree very well with observations of WNh-type Wolf-Rayet stars in the Tarantula Nebula, which are hotter and more compact than would be expected by standard models. The improved models explain the very high temperatures at the surface and the stability of hydrogen, which address previous challenges.

One key subject in this study is R136a1 — the most massive known star — with a mass up to 230 times that of the sun. The researchers suggested that it either formed as a single star of around 200 solar masses or as a binary star system where the two stars had a combined mass of about 200 solar masses. In both such cases, the star must have lost a huge amount of mass early in its life, so the findings would call into question how it is that massive stars can live long enough to leave such a wreckage in the Large Magellanic Cloud.

The implications extend to black hole formation as well. More massive stellar winds erode more mass, resulting in the production of smaller black holes and decreasing the chances of creating elusive intermediate-mass black holes. This revision also enhances the matches of the model with the observed gravitational wave signal of a coalescing black hole binary.

Although the models are restricted to stars in the Tarantula Nebula, the researchers stress that in order for their findings to be considered universal, it is important to understand stars in different chemical environments as well. The results not only reshape predictions of black hole populations but may also adjust our understanding of how the most massive stars in the universe live — and die.

New Interstellar Comet 3I/ATLAS Speeds Through Solar System

Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event



For the first time, a team of astronomers has captured a clear image of a white dwarf star that exploded not just once, but twice, as a Type Ia supernova — a “double-detonation” that scientists hadn’t thought possible until now. The extraordinary observation could revise our long-held notions of how stars die, suggesting that some stars can explode as supernovas without ever crossing the Chandrasekhar limit, the minimum mass normally thought necessary for such an explosion. The astronomers employed the Very Large Telescope’s MUSE instrument to zoom in on the four-century-old supernova remnant SNR 0509-67.5, which sits 60,000 light-years away in the constellation Dorado, revealing evidence of two separate blasting catastrophes in its construction.

First Visual Proof Shows White Dwarfs Can Explode Twice Without Reaching Chandrasekhar Limit

As the researchers report on July 2 in Nature Astronomy, the team found a distinctive “fingerprint” in the debris of SNR 0509-67.5 in the Large Magellanic Cloud that the models predicted. White dwarfs—which are the dead stage of sun-like stars—usually blow up into Type Ia supernovas after they hit the Chandrasekhar limit by stealing matter from a neighbouring star.

However, this finding shows that the detonation can be launched at an earlier time. The explosion is likely to have a two-step origin, the team argues, with the initial blast being generated when an unstable layer of helium that the star had acquired exploded on its surface; the resulting shock wave then drove a second and main detonation.

“This physical proof of a double-detonation not only helps solve a long-standing mystery of what causes these explosions, but it represents the most visually compelling evidence for this origin.” Priyam Das, University of New South Wales, team leader and author.

Something is happening to Type Ia supernovas, the “standard candles” used to measure cosmic distances, because their brightness doesn’t fluctuate. But they have long mystified scientists with how they explode. Until this discovery, an explosion white dwarf that didn’t surpass the Chandrasekhar limit was only considered in theory.

This fresh visual evidence for the double detonation model further informs our knowledge of stellar evolution and also informs how we should interpret light from distant supernovas. More than its scientific implications, its discovery adds a colourful new page to the story of dying stars — stars that, as it now appears, will not go gently into that night but will light up the sky twice over in fantastic fireworks before vanishing from the cosmos.
