Fifty per cent off: Close to flagship-level ANC, now at a great price
It might have become a mainstream feature in headphones but the quality of Active Noise Cancellation (ANC) often fluctuates depending on their price. While you can get headphones with ANC for as little as Rs 2,000, the ANC on them often cancels out very little noise. If you really practical ANC – the type that blocks out a fair amount of external noise – then you generally need to spend in excess of Rs 10,000. Well, until recently. For, thanks to a price cut, the Sony WH-CH720 headphones are now available for well under Rs 10,000, a drop of almost fifty per cent from their original price. Sony launched the WH-CH720 in 2023 as its budget ANC offering. While the headphones were initially available at a price of Rs 9,990, their price shot up substantially in the days that followed, going up to Rs 14,990. And Rs 14,990 remains their official price even today. However, they are often available at much lower prices, going down to almost Rs 7,000 – Rs 7,500 on many e-retailers, most notably Amazon. At the time of writing this piece, the Sony WH-CH720 were available on Amazon for Rs 7,551 and at Rs 7,994 at Croma, which is close to half their official price and also come with bank offers that further reduce their price. For instance, at the time of writing, the WH-CH720 came with a Rs 1,000 flat discount on all bank cards on Amazon, making their price effectively Rs 6,500. We think that even at their official price of Rs 14,990, the Sony WH-CH720 are a pretty good deal. At almost half that price, they get into the steal category. And that is because even more than two years after their release, these headphones pack quite a punch. Their design has remained totally unchanged, although Sony has recently added a very eye-catching pink colour to the existing options of black, blue and white. Although made mainly of plastic, they have a very premium look to them and have a design very similar to the ULT range of bass heavy headphones Sony released in 2024 – round cups connected with a headband. At 192 grams, these are among the lightest ANC headphones we have ever used – some might say they are even too light, although they have a solid feel to them. Both earcups and headband have padding on them, although we would call it adequate rather than generous. The headband does not exert too much pressure on your head, allowing you to wear these for hours without any discomfort. Controls are through buttons (no touch touches) with volume and ANC controls on the left earcup and on/off controls on the right (with a USB Type-C port for charging and 3.5 mm audio jack as well). All in all, the WH-CH720 cut a very smart figure (the pink ones look stunning) and thanks to their light weight and cushioning, are very comfortable to wear. Mind you, there is no carrying case in the box, and as the earcups can only rotate 90 degrees, they cannot fold totally inwards, which makes them a little bulky. The Sony WH-CH720 sound very good too, if you are mainly seeking clarity and a relatively balanced output. The headphones come with 30 mm drivers, and while they do not have the bass-centric sound that many Sony headphones have (you can tweak this using the equaliser options available in the companion app), they sound pleasant enough for most mainstream hearing tasks, whether it is casual listening to music, podcasts and watching films and shows. The sound stage is not the widest, but for their current price, they are comfortably among the best wireless headphones out there in terms of audio quality, although they do not come with support for Sony's own LDAC format (they support the more mainstream AAC and SBC). This is not audiophile level sound, but then you do not get that from any set of ANC headphones at this price point. Volume levels are very good, with quality not getting compromised even at high volumes (we generally found ourselves using these at about 75 per cent volume). There is support for 360 degree sound, but that is available only through limited (and paid) apps. While their audio quality is good, the best reason for investing in the Sony WH-CH720 is their noise cancellation. Most sub-Rs 10,000 ANC headphones come with very basic ANC that cancel out some noise, but are of little use in really noisy conditions. The WH-CH720, however, deliver the kind of ANC that we are used to at much higher price points, and are close to what you get from premium flagships. They largely removed regular traffic noises and the hum of the metro and even killed a lot of the chatter in the cafes where we worked. What's more, they come with Adaptive Sound Control, which changes the level of ANC, depending on your location and activity. This detects four conditions – staying, walking, running and riding a vehicle and adjusts the noise cancellation accordingly: ANC is turned on in staying, and riding a vehicle, while it is reduced or removed altogether and ambient sound mode is activated when you are walking or running, letting external sounds come in. You can even change settings for different locations using the very handy companion mode. The ambient sound mode is very good too, and actually quietens other sounds and keeps voices louder. As we said, this is the kind of facility you get in flagship phones. Another highlight of the WH-CH720 is their battery life. Sony claims 35 hours of battery life with ANC and 50 hours without, and the headphones deliver that. We found ourselves getting through a week easily on a single charge with 4-5 hours of daily usage, even while using ANC. Charging them does take time, though – a 33W charger took about three and a half hours to charge them fully after they got drained. They are not perfect, but the Sony WH-CH720 do deliver a lot at their current price of around Rs 7500. Audiophiles might wish for a more pristine sound, and even those who like to work on the move might expect a case to carry them, or greater foldability. Their being light is also a bit of a mixed blessing – we have been a little terrified that they might break, although they have been around for more than a year. But all of those quibbles fade into insignificance when you consider what these headphones deliver – very good audio quality for mainstream users, excellent battery life and best of all, superb ANC, which is comfortably the best in not just its price segment but even up to Rs 15,000. If you are looking for headphones with great ANC and are on a relatively tight budget, grab these. If you play your cards right (pun intended), you could even get them for Rs 6,500- Rs 7,000, which makes them staggering value for money!

Sudarshan Chakra that cut Pak power: Tracing S-400's journey as India awaits full strength by 2026
India's S-400 'Sudarshan Chakra' took down five Pakistani fighter jets and a surveillance aircraft during Operation Sindoor. With delays from the Ukraine war pushing timelines, the full system is now set to be operational by 2026. Here's the journey read more Indian Air Force (IAF) Chief Air Chief Marshal Amar Preet Singh has revealed that India's S-400 Triumf air defence system, locally dubbed the 'Sudarshan Chakra', shot down five Pakistani fighter jets and one airborne early warning and control (AEW&C) aircraft during Operation Sindoor, marking the largest-ever recorded surface-to-air kill for India. Speaking at the Air Chief Marshal LM Katre Memorial Lecture in Bengaluru, Singh said the AEW&C aircraft was targeted at a range of about 300 kilometres, confirming for the first time the scale of Pakistan's aerial losses in the April operation. The system also intercepted multiple drones and missiles during the mission. STORY CONTINUES BELOW THIS AD From Moscow to the Himalayas First developed in 2007, the Russian-made S-400 was originally deployed for the defence of Moscow, later serving in Syria to protect Russian assets, and in Crimea after its annexation from Ukraine. India signed a $5.43 billion deal in 2018 for five S-400 regiments, with deliveries initially planned to conclude by 2023. However, the Russia–Ukraine conflict and resulting supply chain disruptions pushed back the timeline. The first regiment arrived in December 2021, followed by the second in April 2022 and the third in October 2023. These are now operational along India's western and northern borders, covering both Pakistan and China. Full power in India by 2026 The fourth and fifth regiments are set to arrive from Russia in February and August 2026, respectively. Each S-400 regiment can deploy multiple interceptor missiles capable of destroying aircraft, drones, cruise missiles, and ballistic missiles at ranges up to 400 km. After induction, the system was rechristened as Sudarshan Chakra, a nod to its role in safeguarding India's skies. Defence sources say talks are underway for additional batteries to bolster coverage.

Ray-Ban Meta glasses review: A stylish AI gadget with room to grow
The idea of an AI wearable has always fascinated me. But smart glasses? Yes, cool technology, but can they be your everyday companion? I recently got my hands on the Ray-Ban Meta AI smart glasses. I tried the classic shiny black with clear transition lenses with a standard fit. Meta, in partnership with Ray-Ban, has been pushing its smart glasses lineup for over a year now. The smart glasses come with blue-violet light filters that protect eyes from screens, indoor fluorescent lights, and even sunrays. This made it easier for me to wear it at work, watch TV, scroll through Reels on Instagram, and even while reading books. It is shipped in the standard Ray-Ban packaging with a synthetic leather case that doubles as a charging dock. The box contains a pair of glasses, a charging case, a cleaning cloth, and the usual literature. It does not include a USB-C cable. While the case feels woody and is great to hold, the glasses are made of polycarbonate and seem durable and lightweight. On the surface, anyone sporting the Ray-Ban Meta would be assumed to be wearing a pair of prescription glasses, endowing it with invisibility. The clear transition lens makes it an obscure pair of spectacles indoors, while outdoors it turns into stylish sunglasses. Once outside during daylight, the lenses take a few minutes to darken; similarly, they clear up within seconds after you are indoors. The seeming invisibility of the glasses extends to social situations, as those around would barely notice this piece of tech. On the design front, the integrated camera and LED indicator are delicately integrated into the frame, making them look like decorative elements. The indicators are a functional addition, as they light up every time the cameras are in use. This is a great way to let others around know that the smart glasses are recording. On the other hand, the other LED light that blinks each time you take out the glasses is barely visible, unless someone stands closer to you. This discreteness is great, as no one wants to be pried upon each time they step out wearing smart glasses. If only it had an LED to indicate if someone was engaged in a call. The smartglasses feel sturdy and offer a snug fit. Considering it packs rich-sounding stereo speakers in the stem, the glasses feel light and easy to use. While traditional glasses, plastic or metal, can be bent or reshaped to get a custom fit, Ray-Ban Meta cannot, as the frames are packed with electronics. In case you are planning to buy a pair, I recommend trying them on first. Wear them for a few minutes, feel the pressure points, and assess the weight-related discomfort. Although Meta offers different styles and sizes, issues related to fit are common. Regardless, users can find silicone holders on the temples to keep the frames in place. Be mindful that any attempt to bend the frames may render the warranty void. For those planning to opt for prescription glasses, Meta and Ray-Ban do offer them. However, it is advisable to use certified eye care providers to fit the lenses. The glasses feature touch controls that I found to be surprisingly intuitive. You can adjust the volume with backward and forward swipes, double-tap for calls and music control, and the dedicated camera button on the stem works just the way it should. One can also customise the capture button, such as a single press for video or photo. I found the seamless transition between regular glasses and hands-free AI to be cool. This is the first time I am using open-ear speakers, and I am impressed. I could listen to music, podcasts, and all kinds of audio content. Remarkably, the dual speakers project sound directly into your ears using a technology that feels like wearing traditional earphones. The sound quality is good considering the tiny size of the speakers. Even at moderate volumes, it is perfectly audible while staying inaudible to others. However, the audio leaks a bit if you turn up the volume to the max. I have been wearing the Ray-Ban Meta while working with ambient music in the background. Be it lo-fi for work or classic rock for leisure, the speakers sound incredible. Beyond music, phone calls came through crystal clear. Video and photo capturing is one of the unique aspects of these glasses. These are not iPhone cameras, and they shouldn't be, but the output quality is impressive. The device features a 12MP camera that is located in the corner of the right lens. It can be great for POV shots, especially if you are planning to throw a surprise party for your loved one on their birthday. The glasses can capture a memorable POV video of you carrying a cake to surprise them. The absence of a smartphone or carrying around a GoPro and still being able to capture moments effortlessly seems quite liberating. The videos and images are adequate for social media posts, especially Instagram stories and Reels. However, the camera does not have vertical recording capabilities yet, and this may upset some creators. Below are some unfiltered images clicked using the Ray-Ban Meta glasses: The 12MP ultra-wide camera is capable of recording 1080p videos and supports livestreaming for up to 30 minutes. The video resolution is crisp. While you may not be able to create Reels, you can definitely add some action to your Instagram Stories. The smart glasses come with 32 GB of flash storage, enough to store thousands of photos and hundreds of videos. This could be one of the best use cases of Meta AI integration. Even with some limitations, it works well, as it can identify objects, read text, and offer contextual information about what one is looking at. The responses sound sophisticated, yet at times they lag and may not be accurate. The limitations with AI on this device are a bit arbitrary; it can read images and identify objects, but it fails at times. It often requires specific instructions or phrasing to understand requests. These seem annoying, but it is a good starting point. While using it, I found that natural speech patterns may not always work, and users may need to reword or adapt their way of communication to get thorough results. It does feel like regression, especially when AI is expected to understand natural language. Perhaps hands-free interaction is the most useful feature of the glasses. Some features, like Live AI sessions that let you walk around and ask questions, and Be My Eyes, which can offer real-time assistance to visually impaired users, are remarkable. The glasses can translate conversations in real-time between English, French, Italian, and Spanish. The feature works offline once language packs are downloaded. It can be activated by saying, 'Hey Meta, start live translation.' As of now, its responses are inconsistent, and it struggles with context memory, as it keeps forgetting conversations after each session. It also often misidentifies objects, offering vague answers. It handles web searches and can also offer turn-by-turn navigation. Overall, I found the AI features fun but limited. When it comes to battery life, the Ray-Ban Meta falters, as it is not quite an all-day smart glasses. If you heavily use voice assistants, camera, music, or AI, you could do so for about three to four hours. A useful tip I found on the internet was to disable the always-listening AI feature, as it could extend the battery life by an hour. Charging the case once every four to five days will be enough for most users; this makes the overall power management decent. The Ray-Ban Meta, despite its limitations, comes with some interesting use cases. It can be your go-to outdoor sunglasses owing to the transition lenses or driving glasses with hands-free commands, music, and navigation prompts that can be great for road trips. It can be a great accessory for casual errands, such as quick AI queries and capturing POV pictures and videos without relying on your phone. Indeed, a cool gadget. It is so far one of the most stylish pieces of tech in the eyewear space today. It is comfortable to wear, comes with handy AI features, and offers a glimpse into the future of communication. Those considering them as their only pair of prescription glasses may need to think twice. These smart glasses come with fit issues, limited battery life, and reliance on proprietary charging cases, making them somewhat difficult for full-time use. Ray-Ban Meta smart glasses are a fun, futuristic device; however, they are yet to become the ultimate all-day wearable as we would hope for.
