Several notable names have joined Epic Games in taking a stance against Apple's decision to charge a fee for iOS payments made outside of the App Store. Meta, Microsoft, X and Match Group filed an amicus brief in the case, as The Wall Street Journal reports. That lends some heavyweight backing to Epic's cause.

Apple was forced to enable third-party payments on iOS due to the European Union's Digital Markets Act (DMA) and a court ruling in the US. It also has to allow alternative app marketplaces on iOS in the EU. The company takes up to a 30 percent cut of App Store purchases. Perhaps fearing that it was about to lose out on a significant chunk of commission, Apple said it would charge a fee of up to 27 percent when developers process purchases outside of the App Store.

Epic this month filed a petition asking District Judge Yvonne Gonzalez Rogers to enforce a permanent injunction she issued against Apple in 2021 as part of her ruling in the case between the two companies. The decision compelled Apple to allow developers to direct users to alternative payment systems.

Most of Rogers' ruling was in Apple's favor, however, and both companies appealed the decision all the way up to the Supreme Court. However, in January, the highest court in the US declined to hear the appeals. That means Rogers' permanent injunction against Apple stood, but Epic was not happy about the way Apple implemented the third-party payment changes.

The four companies supporting Epic's petition claim that the fee Apple is charging on external payments effectively leaves the previous rules in place. "The Apple Plan comports with neither the letter nor the spirit of this Court's mandate," their brief states.

As X put it, the 27 percent fee doesn't give developers much incentive to link to external payment methods. Microsoft, which has been working on its own mobile game store, noted that Apple's latest policy limits its ability to offer users subscriptions and discounts. Match Group argued that Apple's decision will affect many developers and users, and that it stymies the court's attempt to offer consumers competition on pricing.

Meta, meanwhile, charges more for its ad-free plans and boosted posts on its iOS apps than it does on the web. (The ad-free subscription is also more expensive in the company's Android apps, as Google takes a cut of in-app payments too). Meta states in the amicus brief that it ought to be able to direct users to other payment options for boosted posts.

Apple claims to have complied with the court order. According to the Journal, the company (which is reportedly facing a Justice Department antitrust case) says its current external link policies are important to protect user privacy and security. Apple has also been dinged over its compliance with the DMA, with critics suggesting the company might be adhering to the letter of the law, but not its spirit. 

For what it's worth, Meta, Microsoft, X and Match Group filed their petition one day after the EU's antitrust chief warned Apple over new fees it's charging developers (and Meta over its ad-free subscription). Margrethe Vestager told Reuters that feedback from developers would play an important factor in whether the bloc investages Apple, Meta or any other company subject to the DMA's rules. She noted that she had received "quite a lot" of comments from third parties.

Meanwhile, Epic is gearing up to debut its game store on both iOS and Android later this year. The company said at the Game Developer Conference that the store would be cross-platform between mobile, PC and macOS. The company plans to charge developers of mobile games the same 12 percent cut it takes from PC game sales.

Amazon has kicked off its latest multi-day deals event, dubbed the Big Spring Sale. Although this event isn't nearly as heavy on tech deals as summer Prime Day, there are still a few good gadget discount to note. If you're specifically looking for a new Apple device, we've compiled the best Apple deals we could find below. In truth, the pickings are pretty slim — and those specifically on the market for a new iPad should probably hold off for now (check out our note below) — but we'd be remiss not to mention a few good offers on the AirPods Pro, Apple Pencil and MacBook Air. Here are the best Amazon Big Spring Sale Apple deals we could find. We'll update this post if more worthwhile discounts arise. As a reminder, Amazon says the Spring sale will run through March 25 and isn't exclusive to Prime subscribers.

A quick PSA on iPad deals

Most people should hold off on buying a new iPad right now. Apple is widely expected to announce new tablets in the coming weeks, with past reports suggesting that we'll see two new iPad Pros, a refreshed iPad Air and an all-new Air model with a 12.9-inch display. That said, neither the 10th-gen iPad nor the iPad mini are expected to be updated until later in 2024, so if one of those slates suit your needs and you absolutely must buy a new tablet today, both should be a little safer to buy than the iPad Air or iPad Pro. (Or the older 10.2-inch iPad, which is likely to be discontinued with the next round of refreshes.) We'll highlight a couple of decent prices on those devices below.

Apple’s second-generation Apple Pencil is down to one of the best prices we’ve seen yet in an Amazon Big Spring Sale deal. You can grab one for just $79, which is a 39 percent discount and $50 off its normal $129 price tag. This is the pencil that's used with most of the latest iPads (except for the 9th-gen tablet) and we consider it to be one of the best iPad accessories you can get.

The second-generation Apple Pencil is great for artists and note-takers who make heavy use of their iPads. It works with the iPad mini (sixth generation), iPad Air (fourth generation and later), the 12.9-inch iPad Pro from the third generation on, and all 11-inch iPad pro models. When it comes to choosing a stylus for your iPad, you really can’t do any better than the Apple Pencil, as it’s designed specifically to be used with Apple’s tablets. It boasts pressure sensitivity for a more realistic drawing experience and has a hover feature that will preview your pen marks to improve precision.

The second-generation Apple Pencil also has a customizable double-tap feature so you can have easier access to the tools you use the most. It charges wirelessly as well, when it’s magnetically attached to a compatible iPad. Apple’s second-generation Pencil was also designed with a more practical flat edge on either side, so it’s less likely to roll off the table when you set it down.

This model of the Apple Pencil came out a few years ago, but it’s still the best of the current lineup. There have been rumors for months that Apple is planning to release new Apple Pencils, possibly as soon as this spring, but that has yet to be confirmed by the company itself. In the meantime, the second generation Apple Pencil is as cheap as the less feature-rich USB-C Apple Pencil.

Amazon has kicked off its latest multi-day deals event, dubbed the Big Spring Sale. The retailer's latest attempt at stirring up sales isn't as big on tech deals as its summer Prime Day event, but it still has a few gadget discounts of note, which we're rounding up as the sale goes along.

The Google Pixel Tablet is one of the better options for those dead set on an Android slate, as it doubles as a sort of smart display when hooked up to an included charging speaker dock. If you've been interested, now looks like a decent time to take the plunge: The 11-inch tablet is back down to $399 at multiple retailers, including Amazon, Target and the Google Store. 

Google ran this deal a few times toward the end of last year, but it matches the lowest price we've seen and comes in $100 below the 128GB model's usual going rate. If you need more storage, the 256GB version is $150 off and available for $449, another all-time low. The offer comes as part of a wider spate of sales on Google devices and just ahead of Amazon's "Big Spring Sale" sales event. Google says these deals will run through April 3.

My colleague Cherlynn Low gave the Pixel Tablet a score of 85 in her review last June, and we note the device in our tablet buying guide. The aforementioned dock is really what helps it stand out: Plop the tablet onto that and it becomes something akin to a detachable Nest Hub Max. It doesn't have all the same functionality, but you can use it to control smart home devices, showcase photos, stream music with the improved speakers, cast video from your phone and so on. It all makes this the rare tablet that can be useful even when when you aren't holding it. 

Without the dock, the Pixel Tablet isn't quite as remarkable: Its LCD display is limited to a basic 60Hz refresh rate, its Tensor G2 chip is now a generation old and Google doesn't support it with a custom-made keyboard or stylus. The screen's rectangular 16:10 aspect ratio may take a bit to get used to as well. Samsung's Galaxy Tab S9, the top Android pick in our guide, costs a few hundred extra but has more premium hardware and better tools for getting work done. And all Android tablets still lag behind Apple's iPadOS when it comes to optimizing apps for large displays. 

That said, even if it's not superlative, the Pixel Tablet is still perfectly solid for web browsing, streaming video and playing games. Unlike the iPad, it also supports multiple user profiles, so it's a good choice if you want share one tablet with everyone in your family. Google says it'll supply OS updates through June 2026 and security updates through June 2028. There's at least some chance that a follow-up device is in the works, but for now, this is a decent deal if you want a big-screen Android device.

Replacing a smartphone every two years is partially why billions of phones go into landfills each year. If stacked flat atop one another, that many handsets would reach farther than the ISS. But we’ve become accustomed to that 24-month time frame because wireless carriers often push an upgrade on biennial contracts, and many smaller phone makers only offer software support for two years. But now, with longer software commitments from major manufacturers, along with growing right-to-repair legislation, many newer phones can stay in our pockets for closer to seven trips around the sun. Here’s how you can extend the lifespan of your smartphone and avoid shelling out hundreds before it’s absolutely necessary.

How to make your smartphone last longer

Engadget

Use a case

It’s a flashy move to carry a naked phone around, but the chances of a handset making it through a tumble go up dramatically when you employ extra protection. We recommend a number of them in our guide to iPhone cases and in our eco-friendly phone cases guide. In my family, we’ve been happy with Mous cases. Though we’ve never subjected our phones to the brutality seen in the company’s ads, I can say that these cases have seen my partner’s aging Samsung Galaxy and my elderly iPhone through some pretty gnarly spills, sparing them from scratches or worse.

Take care of the built-in battery (or use a power bank)

Since a phone’s battery is often the first thing to show signs of age, it’s worth it to follow recommendations for extending its lifespan. Lithium-ion batteries don’t perform well in heat and you should avoid charging them if it’s hotter than 95 degrees — doing so can degrade the battery quickly and even cause them to malfunction. They’ll tolerate cold weather better, but can get sluggish when things get too chilly.

If you’re storing a phone for a while, it’s best to do so with the battery at half charge, rather than full or empty. In fact, Li-ion cells last longer when they spend less time being either completely discharged or full — that’s why battery optimization features in iPhones and Pixel phones delay overnight charging to 100 percent until about an hour before you typically grab your mobile. And while it’s sometimes necessary to charge a battery quickly, a slower charging method when speed isn’t critical will put less stress on the ionic components and help extend the cell’s life.

But over time, any battery will eventually wear down. The cell powering my iPhone 11 can make it through a typical day, but if I’m traveling, relying heavily on navigation or using the phone as a hotspot, it’ll need a top-off before bedtime. That’s easy if I’m home, but out in the world, a battery pack is an essential. I have a slew of them on hand after testing for our best power banks guide and the two I grab most often are the Otterbox Fast Charge, because it looks cool and has a good capacity, and the Nimble Champ Pro, because it’s crazy fast.

If you really want to give your phone a new lease on life, a new internal battery could be the ticket. For Pixel phones, you can go through Google’s official channel for either a walk-in or mail-in repair, or you can pick the DIY route with iFixit’s Pixel repair kits and instructions. For iPhones, you can start with Apple’s official page, go through Best Buy or other third-parties, or try iFixit’s methods. Samsung also has an in-house option, or you can try Best Buy or iFixit. Depending where you go and the model of your phone, the price for a new battery and installation will likely run you between $45 and $150 — still far less than ditching your handset for something brand new.

Clean up your phone’s storage

Most advice on how to declutter your phone and make it run faster centers on one thing: freeing up space. Your phone’s OS will likely have suggestions for clearing up storage space, like automatically offloading unused apps or deleting year-old messages. You can also do things manually by deleting any apps you don’t use. Next, consider the photos and videos you’re storing locally and either opt to pay for cloud storage or transfer the files to a computer or an external backup device. You can also consider getting rid of any music and movies you may have downloaded for offline use, and deleting old messages and large attachments. A good rule is to keep your storage at around 80 percent capacity. Once you’ve deleted and transferred what you can, restart your phone to give it a chance to clear up its temporary memory.

Why you can (and should) extend the life of your smartphone

The e-waste stream grows each year and doesn't do great things for human or planetary health. Smartphone companies are offering better and more consistent trade-in deals, but even some electronic recycling has its faults. Simply hanging onto a device instead of opting for a new one is the most efficient way of cutting back on a phone's environmental impact — plus it'll save you money.  

While every giant phone maker would like you to believe that upgrading annually is critical, it’s worth noting that new generations of phones often bear strong resemblance to the prior year’s model. We called both the latest iPhone and Google Pixel the most significant updates in years, but prior to that, upgrading didn’t make much sense. The latest Samsung Galaxy phone has a slew of new AI tricks, but physically, it’s not much different than the one that came before it.

With only minor hardware upgrades, the more exciting new features come via over-the-air software updates. When Google released the Pixel 8 last October, the company promised security and software updates for a full seven years. Samsung came out with the Galaxy S24 in January of this year and committed the same support for its handsets. Apple hasn’t made the same pledge, but when the launch of iOS 17 last year cut support for the iPhone 8 and iPhone X, both models had enjoyed around six years of updates from launch.

What Apple did announce is that the batteries in all four models of the iPhone 15 last twice as long as the company originally claimed. Originally, battery capacity was listed at 80 percent of the original full charge after 500 cycles. Now, that same capacity rate applies to 1,000 cycles. The improvement, Apple says, comes courtesy of advanced battery tech and better power management from the operating system. It’s true battery technology has improved in capacity over the years, but longevity hasn’t gone up across the board, as a study by PhoneArena makes clear.

More advancements in battery life spans may be on the horizon particularly as the EV industry grows, which also relies on lithium-ion cells. For now, declining battery health is usually the most noticeable issue affecting older phones. This year, the European Parliament voted for rules surrounding battery-powered devices and included a mandate to allow consumers to “easily remove and replace” batteries. That won’t go into effect until 2027, and there will be plenty of interpretation as to what “easily” means. But EU mandates are what made Apple finally ditch Lightning ports on iPhones in favor of USB-C, so this could eventually be a step towards (once again) having smartphones with swappable batteries.

Even in the US, legislation will soon compel companies to make repair a better option. Right-to-repair bills were passed last year in New York, Minnesota and other states. California has the strongest rule, and it even garnered Apple’s support. Once the law goes into effect in July, it will require companies to provide repair tools and documentation, and to sell components for seven years after the last new model is made for any device costing more than $100. Of course, the law didn’t say anything about prohibiting “parts pairing,” in which a device only works properly when repaired with official parts by a manufacturer-authorized repair center.

Currently, a number of phones have decent repairability scores, according to the online repair community iFixit (the FairPhone 5 gets the highest marks). After California’s law goes into effect, more models may become user-repairable, considering few manufacturers are likely to ignore the state’s nearly 40 million customers. In the meantime, authorized repair is an option, as is self-repair for the more industrious.

Apple’s second-generation Apple Pencil is down to one of the best prices we’ve seen yet in a deal on Amazon. The gen 2 Apple Pencil is going for just $79, in what amounts to a 39 percent discount. It’s normally $129, so this would save you $50 on what is the best stylus for the iPad (as long as you have a compatible model).

The second-generation Apple Pencil is great for artists and note-takers who make heavy use of their iPads. It works with the iPad mini (sixth generation), iPad Air (fourth generation and later), the 12.9-inch iPad Pro from the third generation on, and all 11-inch iPad pro models. When it comes to choosing a stylus for your iPad, you really can’t do any better than the Apple Pencil, as it’s designed specifically to be used with Apple’s tablets. It boasts pressure sensitivity for a more realistic drawing experience and has a hover feature that will preview your pen marks to improve precision.

The second-generation Apple Pencil also has a customizable double-tap feature so you can have easier access to the tools you use the most. It charges wirelessly as well, when it’s magnetically attached to a compatible iPad. Apple’s second-generation Pencil was also designed with a more practical flat edge on either side, so it’s less likely to roll off the table when you set it down.

There have been rumors for months that Apple is planning to release new Apple Pencils, possibly as soon as this spring, but that has yet to be confirmed by the company itself. In the meantime, the second generation Apple Pencil is as cheap as the less feature-rich USB-C Apple Pencil.

One of the best things about the Android ecosystem is the availability of truly affordable phones for as little as $150. By comparison, the cheapest iPhone is based on a dated design and starts at $429. However, picking the right one can be a bit tricky, as reducing the price of a phone can sometimes result in too many trade-offs. So to give you a hand, we tested a bunch of the most popular options and put together a list of our favorite cheap Android phones.

How low should you go?

We tend to define a budget phone as costing between $150 and $350. Any lower and the device runs the risk of suffering from too many compromises, and above that, you cross over to pricier midrange handsets (if you're open to spending more, we shouted out a couple of our favorites at the very end of this guide).

But for those with a little wiggle room, there are some things to consider. For example, a child may be better off with a cheaper device, especially if it’s intended mainly for emergencies or texting parents (and not social media). On the higher end of this price spectrum, sub-$350 phones have come a long way thanks to improved performance, better cameras and nicer displays. This makes them a viable alternative to premium flagships, even if you have the freedom to spend more.

What to look for in a budget Android phone

When it comes to affordable devices, you get what you pay for. Most phones in this price range are made out of plastic, though the fit and finish of a specific model can vary a lot based on price. A bright screen is also important. Typically you’ll get LCD panels with a 60Hz or 90Hz refresh rate, but some phones may have OLED screens with increased color saturation. Long battery life is critical as well, so we tend to favor devices with larger power cells of around 5,000 mAh. In this price range, performance can vary a lot, so look for devices with at least 8GB of RAM and processors that can deliver stutter-free visuals. It’s also important to consider support length, as periodic operating system and security updates can extend the longevity of your device, which will save you money in the long run.

Samsung’s Galaxy Tab S9 is on sale for $680 via Amazon, which is a discount of $120. This is a record low price for the well-regarded tablet. The S9 is the most recent iteration and there likely won't be a refresh on the horizon until at least September.

Now onto some specs. The standard S9 boasts an 11-inch AMOLED screen, a Snapdragon 8 Gen 2 processor and 12GB of RAM. It also comes with the company’s S Pen stylus, which is something I wish Apple did for its tablets. The $680 price tag gets you a device with 128GB of internal storage, but 256GB and 512GB models are also on sale. 

The Galaxy Tab S9 easily made our list of the best tablets, and for good reason. We loved the gorgeous AMOLED screen, the powerful speakers and the tablet’s surprisingly useful Dex multitasking mode. For the uninitiated, this mode basically turns the tablet into a PC, complete with standard windows, folders and a taskbar, with the ability to drag and drop files.

The 11-inch screen is a joy to behold and probably the best fit for most people. The S9+, which is also on sale, boasts a particularly large 12.4-inch AMOLED display. Those with small hands should probably demo that unit before making the splurge. 

This is part of a larger Amazon sale on a bunch of Samsung tablets. There’s the aforementioned S9 tablets with more hard drive space, but also discounts on the entire A9+ line and the S9 FE+. There are no deals, however, for the top-of-the-line S9 Ultra.

“When you think about the history of Bluetooth, and specifically about audio, you really have to go back to the mid-to-late ’90s.”

Chuck Sabin is a Bluetooth expert. As a senior director at Bluetooth Special Interest Group (SIG), he oversees market research and planning as well as business development. He’s also leading the charge for emerging uses of Bluetooth, like Auracast broadcast audio. In other words, he’s an excellent person to speak to about how far Bluetooth has come — from the days of mono headsets solely used for voice communication to today’s devices capable of streaming lossless-quality music.

In the mid ’90s, mobile phones were starting to become a thing, and of course so were regulations about hands-free use of them in cars. Sabin previously worked in the cellular industry, and he remembers how costly and intrusive the early hand-free systems were in vehicles. Bluetooth originated from cell phone companies working together to cut the cord to headphones since using those not-yet-wireless audio accessories in the car was cumbersome. One of the first mobile phones with Bluetooth was from Ericsson in the late ’90s, although an updated model didn’t make it to consumers until 2001. That same year, the IBM ThinkPad A30 became the first laptop with Bluetooth built in. At that time, the primary intent of the short-range radio technology was for voice calls.

Bose

“You had a lot of people who ended up with these mono headsets and boom mics,” he explained. You know, the people we all probably made fun of — at least once. Most of these things were massive, and some had obnoxious blinking lights. They’re definitely a far cry from the increasingly inconspicuous wireless earbuds available now.

Bluetooth as a specification continued to evolve, with companies leveraging it for music and streaming audio. To facilitate music listening, there had to be faster communication between headphones and the connected device. Compared with voice calling, continuous streaming required Bluetooth to support higher data speeds along with reduced latency. Where Bluetooth 1.0 was call specific, version 2.0 began to achieve the speeds needed for audio streaming at over 2 Mb/s. However, Sabin says, the 2.1 specification adopted by Bluetooth SIG in 2007 was when all streaming audio capabilities were implemented in automobiles, phones, headphones, headsets and more.

Of course, it would still be a few years before wireless headphones were mainstream. In the early 2000s, headphones were still directly connected to a mobile phone or other source device. Once Bluetooth became a standard feature in all new phone models, as well as its inclusion in laptops and PCs, consumers could count on wireless connectivity being available to them. Even then, music had to be loaded onto a memory card to get it on a phone, as dedicated apps and streaming services wouldn’t be a thing until the 2010s.

“The utility of the device that you carried around with you all the time was evolving,” Sabin said. “Bluetooth was ultimately riding that continued wave of utility, by providing the opportunity to use that phone as a wireless streaming device for audio.”

About the time wireless headphones had become popular, a few companies arrived with a new proposition in 2015: true wireless earbuds. Bluetooth improvements meant reduced power requirements leading to much smaller devices with smaller batteries — and still provide the performance needed for true wireless devices. Bragi made a big splash at consecutive CESs with its Dash earbuds. The ambitious product had built-in music storage, fitness tracking and touch controls, all paired with a woefully short three-hour battery life. Perhaps the company was a bit overzealous, in hindsight, but it did set the bar high, and eventually similar technologies would make it into other true wireless products.

“Companies that were building products were really starting to stretch the specification to its limits,” Sabin explained. “There was a certain amount of innovation that was happening [beyond that] on how to manage the demands of two wireless earbuds.” Bluetooth’s role, he said, was more about improving performance of the protocol as a means of inspiring advances in wireless audio devices themselves.

He was quick to point out that, for the first few years, true wireless buds accepted the Bluetooth signal to only one ear and then sent it to the other. That’s why the battery in one would always drain faster than the other. In January 2020, Bluetooth SIG announced LE Audio at CES as part of version 5.2. LE Audio delivered lower battery consumption, standardized audio transmission and the ability to transmit to multiple receivers — or multiple earbuds. LE Audio wouldn’t be completed until July 2022, but it offers a lower minimum latency of 20 to 30 milliseconds versus 100 to 200 milliseconds with Bluetooth Classic.

“All of the processing is now done back on the phone itself and then streamed independently to each of the individual earbuds,” Sabin continued. “That will continue to deliver better performance, better form factors, better battery life and so on because the processing is being done at the source level versus [on] the individual earbuds.”

The increased speed and efficiency of Bluetooth has led to improvements in overall sound quality too. Responding to market demands for better audio, Qualcomm and others have developed various codecs, like aptX, that expand what Bluetooth can do. More specifically, aptX HD provides 48kHz/24-bit audio for wireless high-resolution listening.

“One of the elements that came into the specification, even on the classic side, was the ability for companies to sideload different codecs,” Sabin explained. “Companies could then market their codec to be available on phones and headphones to provide enhanced audio capabilities.”

LE Audio standardizes Bluetooth connectivity for hearing aids, leading to a larger number of supported devices and interoperability. The use cases range from tuning earbuds to a user’s specific hearing or general hearing assistance needs, with or without the help of active noise cancellation or transparency mode, to simply being able to hear valuable info in public spaces via their earbuds or hearing aid.

“Bluetooth is becoming integral for people with hearing loss,” he explained. “Not only for medical-grade hearing aids, but you’re seeing hearing capabilities built into consumer devices as well.”

Sony

Sabin also noted how the development of true wireless earbuds have been key for people with hearing loss and helped reduce the stigma around traditional hearing aids. Indeed, companies like Sennheiser and Sony have introduced assistance-focused earbuds that look no different from the devices they make for listening to music or taking calls. Of course, those devices do that too, it’s just their primary aim is to help with hearing loss. The boom, which has been going on for years, was further facilitated by a 2022 FDA policy change that allowed over-the-counter sale of hearing aids.

One of the major recent developments for Bluetooth is broadcast audio, better known as Auracast. Sabin described the technology as “unmuting your world,” which is exactly what happens when you’re able to hear otherwise silent TVs in public spaces. You simply select an available broadcast audio channel on your phone, like you would a Wi-Fi network, to hear the news or game on the TV during your layover. Auracast can also be used for things like PA and gate announcements in airports, better hearing at conferences and sharing a secure audio stream with a friend. Companies like JBL are building it into their Bluetooth speakers so you can link unlimited additional devices to share the sound at the press of a button.

“You’re seeing it in speakers, you’ll see it in surround sound systems and full home or party-in-a-box type scenarios,” he said. Sabin also noted that applications beyond the home could simplify logistics for events, since Auracast audio comes from the same source before it’s sent to a PA system or connected earbuds and headphones with no latency. Sabin said the near-term goal is for Bluetooth audio to be as common in public spaces as Wi-Fi connectivity, thanks to things like Auracast and the standard’s constant evolution.

Even after 20 years, we’re still relying on Bluetooth to take calls on the go, but both the voice and audio quality have dramatically improved since the days of the headset. Smaller, more comfortable designs can be worn all day, giving us constant access to music, podcasts, calls and voice assistants. As consumer preferences have changed to having earbuds in at all times, the desire to tune into our surroundings rather than block them out has increased. “Unmuting your world” is now of utmost importance, and the advancement of Bluetooth technology, from the late ’90s through LE Audio, continues to adapt to our sonic preferences.

To celebrate Engadget's 20th anniversary, we're taking a look back at the products and services that have changed the industry since March 2, 2004.
