Everyone Should Have Exactly Three Pairs of Headphones. These Are My Picks

For everyday use, exercising and lengthy listening time, three is the perfect number for a headphones and earbuds collection. Let me explain.

When most people ask you what your «big three» are, they’re likely inquiring about your sun, moon and rising signs. But when I ask you the same question, I’m not trying to determine your horoscope. Instead, I’m curious what your headphones and earbuds collection looks like.

After more than a decade working as a technology journalist, I’m in the fortunate position of having what most people would consider to be too much tech in my house. I make a real effort to keep it to a minimum and try not to accumulate any superfluous gadgets. But with headphones, I’ve reached the conclusion that everyone needs at least three pairs. No matter how hard I’ve tried, I can’t pare this number back.

First, there are the everyday earbuds. These are the ones that can slide into your smallest bag or your pocket and travel everywhere with you — on your commute, on your errands and on shopping trips.

Second, there are the over-ear, luxury headphones. These need to have that heady combo of great noise cancellation, audio quality and battery life, combined with a level of comfort that means you could easily wear them for an entire long-haul travel day.

Finally, if you’re serious about fitness, you need dedicated workout headphones. Could you wear either of the above pairs to go on a long run? Sure, and plenty of people do. But for the sake of longevity and your sanity, having a sweat-proof, durable pair of headphones that won’t budge may save your sanity in the short term and save you money in the long run.

If you’re trying to make one pair of headphones work in every scenario, you might feel frustrated that none are able to truly deliver the experience you want across the board. This is where my theory comes into play. It really doesn’t matter which headphones you choose for each of these purposes but I do believe they are distinct categories with little crossover.

And what are my big three? They may not be the same as yours but these are the headphones I absolutely can’t live without right now.

My everyday earbuds: OnePlus Buds 3

I will die on the hill that you shouldn’t spend more than $100 on your everyday earbuds — the kind that you will drop, accidentally bash and at some point, inevitably, lose. So much about buds comes down to personal preference on how they actually feel when tucked inside your ears.

Personally, I’ve settled on the OnePlus Buds 3, which list right at $100. They’re aesthetically pleasing in a pale blue that matches my preferred fashion color palette, and I find them to be supremely comfortable. I’ve been using them for a good six months and I don’t have any of the usual niggles I have with earbuds — by which I mean they don’t fall out of my ears or have any random, weird sound glitches.

Soundwise, I enjoy the heavy bass and find the ANC to suit my needs as a frequent traveler on public transportation. With 10 hours of battery life, plus an additional 44 in the case, these buds have never let me down. They’re not necessarily anything special but I keep reaching for them even though I have other options at my disposal.

My luxury over-ear headphones: Dali IO-8

At the other end of the spectrum, my favorite luxury headphones have transformed my longest travel days into periods of prolonged sonic bliss. I wear the Dali IO-8 headphones through airports, on plane journeys, all the way through to checking into my hotel. They also come with me on my daily hot girl walks.

With 30 hours of battery life and decent ANC, they allow me to move through the world in my own little bubble. Not only are they truly the most luxurious and comfortable headphones I’ve ever used, they also provide me with glorious sound.

You can switch between two modes: hi-fi and bass. I usually stick with the former. No matter whether I’m immersed in an audiobook, bopping away to Paramore, spacing out to Sigur Ros or getting lost once again in the depths of Taylor Swift’s back catalog, the $1,100 Dali IO-8s deliver.

My workout headphones: Beats Powerbeats Pro 2

There’s no two ways about it: I’ve tried other workout headphones and I keep coming back to Beats. I’ve been known to tie up my running shoes and be halfway out the door, then calling the whole run off because I can’t find my Powerbeats.

I’ve been a fan since the earliest Powerbeats model but the latest Powerbeats Pro 2, priced at $249, are my favorite workout headphones yet. Once in, they simultaneously feel glued to my head with a tight seal in my ear, while also being so light and comfortable I forget they’re there. This is an essential combination when you’re exercising, as the last thing you want to do is deal with any discomfort or annoyance that might distract from your workout.

CNET’s resident audio expert, David Carnoy, rated the Powerbeats Pro 2 an 8.8 out of 10, noting the improved sound quality and good noise canceling. As someone who’s long been a fan of this line, I have to agree and I’d go so far as to say this latest upgrade has made running to my favorite high-energy tracks more enjoyable than ever.

You Can Watch an Exclusive Avatar: Fire and Ash Scene on TikTok Right Now

Disney and TikTok partner on an immersive content hub for James Cameron’s latest movie about the alien Na’vi.

If you’re not quite ready to head to the theater to watch Avatar: Fire and Ash, an exclusive scene preview might sell you on the visual spectacle. As part of a new collaboration with the social media giant, Disney is posting snippets of its new movie to its TikTok account.

This scene isn’t part of any trailer and won’t be posted to other social media accounts, making TikTok the only place you can view it — unless you buy a movie ticket. A first look at the new movie’s scenes isn’t the only Avatar-related bonus on the social media platform right now, either. TikTok has partnered with the house of mouse to bring an entire «immersive content hub» to the app.

A special section of TikTok includes quizzes and educational videos that explore the alien world of Pandora shown off in the movies. On TikTok, you can take a personality quiz to find out what Na’vi clan you most closely align with and unlock a special profile picture border to use on your account.

Science and fiction blend together with a series of videos from real doctors who explain the basis for some of Avatar’s world-building. If you want to learn about exoplanets or how realistic the anatomy of the movie’s alien animals is, these videos will feed your brain while still providing entertainment value.

Perhaps the most enticing part of Disney’s latest social media collaboration is the opportunity for fans to win prizes and trips. TikTok creators who make edits with the #TikTokAvatarContest hashtag are entered into a competition to win Avatar merchandise. The biggest winners will be able to take a trip to visual effects studio Wētā Workshop in New Zealand or visit Avatar director James Cameron’s Lightstorm Entertainment Studio in Los Angeles.

Avatar: Fire and Ash is the third installment in director Cameron’s cinematic passion project. While the first Avatar movie was released in 2009, Cameron didn’t release another entry in the franchise until 2022. In total, there is a five-movie arc planned for the indigo alien Na’vi on the moon of Pandora.

The Avatar movies are known for pushing the boundaries of CGI visual effects in cinema. They are also historically big winners at the box office: the original Avatar is the highest-grossing film of all time, earning $2.9 billion across its theatrical releases. Its sequel, Avatar: The Way of Water, is the third-highest-grossing film of all time, trailing Avengers: Endgame. You can stream those movies on Disney Plus.

It remains to be seen whether Avatar: Fire and Ash will financially live up to its predecessors. The film currently has mixed reviews from critics on Rotten Tomatoes.

Brain-Inspired Algorithms Could Dramatically Cut AI Energy Use

A new study dives into a major redesign for AI architecture.

One major issue facing artificial intelligence is the interaction between a computer’s memory and its processing capabilities. When an algorithm is in operation, data flows rapidly between these two components. However, AI models rely on a vast amount of data, which creates a bottleneck.

A new study, published on Monday in the journal Frontiers in Science by Purdue University and the Georgia Institute of Technology, suggests a novel approach to building computer architecture for AI models using brain-inspired algorithms. The researchers say that creating algorithms in this manner could reduce the energy costs associated with AI models.

«Language processing models have grown 5,000-fold in size over the last four years,» Kaushik Roy, a Purdue University computer engineering professor and the study’s lead author, said in a statement. «This alarmingly rapid expansion makes it crucial that AI is as efficient as possible. That means fundamentally rethinking how computers are designed.»

Most computers today are modeled on an idea from 1945 called the von Neumann architecture, which separates processing and memory. This is where the slowdown occurs. As more people around the world utilize data-hungry AI models, the distinction between a computer’s processing and memory capacity could become a more significant issue.

Researchers at IBM called out this problem in a post earlier this year. The issue computer engineers are running up against is called the ‘memory wall.’

Breaking the memory wall

The memory wall refers to the disparity between memory and processing capabilities. Essentially, computer memory is struggling to keep up with processing speeds. This isn’t a new issue. A pair of researchers from the University of Virginia coined the term back in the 1990s.

But now that AI is prevalent, the memory wall issue is sucking up time and energy in the underlying computers that make AI models work. The paper’s researchers argue that we could try a new computer architecture that integrates memory and processing.

Inspired by how our brains function, the AI algorithms referred to in the paper are known as spiking neural networks. A common criticism of these algorithms in the past is that they can be slow and inaccurate. However, some computer scientists argue that these algorithms have shown significant improvement over the last few years.

The researchers suggest that AI models should utilize a concept related to SNNs, known as compute-in-memory. This concept is still relatively new in the field of AI.

«CIM offers a promising solution to the memory wall problem by integrating computing capabilities directly into the memory system,» the authors write in the paper’s abstract.

Medical devices, transportation, and drones are a few areas where researchers believe improvements could be made if computer processing and memory were integrated into a single system.

«AI is one of the most transformative technologies of the 21st century. However, to move it out of data centers and into the real world, we need to dramatically reduce its energy use,» Tanvi Sharma, co-author and researcher at Purdue University, said in a statement.

«With less data transfer and more efficient processing, AI can fit into small, affordable devices with batteries that last longer,» Sharma said.
