Amazon Prime Day deal: The OnePlus Buds 3, my top choice for everyday earbuds, are 12% off for Prime Day, dropping the price to $88 from their usual list price of $100. The Beats Powerbeats Pro 2, my go-to for running, are seeing a whopping 28% discount on Amazon. That brings them down to an all-time low price of $180.

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.

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.

It’s officially summer, and with that comes the first full moon of the season. July’s full moon — known as the Buck Moon or the Thunder Moon — will light up the night sky on July 10 and be at its fullest going into July 11. It’ll be bright for the whole night but will reach peak luminosity at around 4:37 a.m. local time, which is a bit late (or early) for most skygazers. 

According to Stellarium’s sky map, the moon will rise from the southeastern horizon just after sunset on Thursday and streak across the sky before setting on the southwestern horizon just before dawn. No matter where you are in the US, you’ll be able to see it virtually all night. 

Should you not be able to see the moon due to weather or some other reason, you can also soak up a great view anytime between July 9 and July 12, as the moon will be more than 95% full during those days. 

Why is it called the Buck Moon and Thunder Moon?

According to The Farmer’s Almanac, July’s full moon actually has several names, including Buck Moon, Thunder Moon, Feather Moulting Moon and Salmon Moon. These names typically come from Native American and colonial times, and were used to describe the moon for the entire month, not just when it’s full. 

White-tailed deer start growing antlers in March or April as the days start to lengthen. July marks the peak of their antler growth season, hence the name Buck Moon. Thunderstorms are also common in July, which is why it’s called the Thunder Moon. 

The other two names are less common, but July marks the time when some species of salmon begin migrating for the mating season, while ducks engage in their annual moulting around this time of year as well. 

Catch a glimpse of Mars and Venus

The moon will be joined in the sky by Mars and Venus during its trip across the sky on July 10. Mars will be visible just after sunset in the western sky before setting. You won’t have long, since it’s scheduled to dip below the horizon before midnight. If you choose to stay up late, Venus will crest the eastern horizon shortly after 2 a.m. local time and be visible until sunrise. 

Saturn will also be visible in the eastern sky, not far from the moon, but you’ll likely need binoculars or a telescope to see it beyond the moon’s glow.

Once the moon finishes its monthly cycle, skygazers can check out the Alpha Capricornids and Southern Delta Aquariids meteor showers, both of which are scheduled to peak during the last few days of July.

The American Federation of Teachers is using $23 million in funds from three tech companies to launch a program to train educators on artificial intelligence.

On Tuesday, the country’s second-largest teachers’ union announced $12.5 million from Microsoft, $10 million in funding and technical resources from OpenAI and $500,000 from Anthropic will be used for a New York-based hub to teach AI. The AFT is working in partnership with the United Federation of Teachers, a union representing New York school workers.

The hub will be called the National Academy for AI Instruction, and according to OpenAI, will serve 400,000 educators to develop AI fluency by 2030 through workshops, online courses and hands-on training sessions. The plan, according to the company, is to start in New York and scale nationwide, including additional hubs elsewhere in the country. The effort will begin with a focus on K-12 educators.

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)  

In a post on X, AFT President Randi Weingarten wrote, «This will be an innovative new training space where educators will learn not just about how A.I. works, but how to use it wisely, safely and ethically.It will be a place where tech developers and educators can talk with each other, not past each other.»

The announcement was not met with unanimous praise. On a post on the UFT’s Facebook page, commenters were not happy. «AI use has been proven to reduce brain activity but sure, why not,» one commenter wrote.

Another wrote, «This is absolutely a horrible decision by the Union. It is undermining our work and also doesn’t take in consideration the ramifications of AI in education.»
