Google has disclosed several security flaws for phones that have Mali GPUs, such as those with Exynos chipsets. The company's Project Zero team says it flagged the problems to ARM (which produces the GPUs) back in the summer. ARM resolved the issues on its end in July and August. However, smartphone manufacturers including Samsung, Xiaomi, Oppo and Google itself hadn't deployed patches to fix the vulnerabilities as of earlier this week, Project Zero said.
Researchers identified five new issues in June and July and promptly flagged them to ARM. "One of these issues led to kernel memory corruption, one led to physical memory addresses being disclosed to userspace and the remaining three led to a physical page use-after-free condition," Project Zero's Ian Beer wrote in a blog post. "These would enable an attacker to continue to read and write physical pages after they had been returned to the system."
Beer noted that it would be possible for a hacker to gain full access to a system as they'd be able to bypass the permissions model on Android and gain "broad access" to a user's data. The attacker could do so by forcing the kernel to reuse the afore-mentioned physical pages as page tables.
Project Zero found that, three months after ARM fixed these issues, all of the team's test devices were still vulnerable to the flaws. As of Tuesday, the issues were not mentioned "in any downstream security bulletins" from Android manufacturers.
Engadget has contacted Google, Samsung, Oppo and Xiaomi to ask when they will deploy the fixes to their Android devices and why it has taken so long for them to do so. As SamMobile notes, Samsung's Galaxy S22 series devices and the company's Snapdragon-powered handsets aren't affected by these vulnerabilities.
Critter & Guitari's lineup of hackable music computers and video synths are undeniably unique. They do things that practically no other instrument can, plus they're probably the most visually distinctive portable music devices out there. Its latest creation is the 201 Music Synthesizer, an arguably long overdue replacement for the company's first product — the Pocket Piano.
Like its flagship Organelle, the 201 is built on open source software, specifically Pure Data and Faust. But rather than trying to be all things to everyone, it's more narrowly focused. It ships with six built-in synth engines covering chiptune-style bleeps, analog-esque sounds, drum samples, physical modeling (likely via Karplus Strong), and vocal synthesis. Rather than four knobs that vary in purpose depending on what patch you've loaded (which may or may not have particularly good documentation, depending on who created it), the 201 has three parameter knobs for envelope, tone and "surprise" — for when you just want a happy accident.
One of the things that makes the 201 really standout though, is the pattern generator and sequencer. While you can simply play notes live and record them for later recall, the synth can also create patterns for you. A couple of presses on the unique maple keys and the 201 will start spitting out simple octave jumps, arpeggios or random polyphonic chaos. And if something strikes your fancy, you can save that as well. And you can save literally thousands of sequences to the included 8GB microSD card.
Like the Organelle, you can actually hack together your own patches for the 201 using Pure Data or Faust, but that's more of a nice bonus than the main selling point here. Under the hood of the 201 is a 900Mhz ARM processor with 512MB RAM, which should be plenty for most synth patches, but it's not quite as powerful as the Organelle M. The 201 also has a built-in speaker, a 1/4-inch stereo out jack, 1/8-inch MIDI in and out, USB-A for connecting MIDI controllers, and USB-C for accessing the files on the microSD card.
Of course, to be a true replacement for the Pocket Piano, the 201 also needs to be portable. So, in addition to the AC adapter, it can be powered by three AA batteries. And at about one pound and a little over nine-inches long, it's pretty easy to toss in a backpack.
The Critter & Guitari 201 Music Synthesizer is currently crowd funding over at Kickstarter and has already surpassed its goal. If you'd like to secure one when they start shipping in April of 2023 you can back it before December 20th for $295.
Black Friday may still be a few hours away, but we're already seeing a bunch of great deals on our favorite tech. This comes after a slow trickle of deals popping up across the web ever since the start of November. While we don't have the supply chain issues we did last year, it's still a good idea to start your holiday shopping as early as possible — even if it's just a few hours before the biggest sale day of the year. The sooner you check off items from your list, the sooner they'll arrive and you'll be ready to go for the holidays. To make things easier for you, we've collected the best early Black Friday tech deals here so you don't have to go searching for them.
Bose QuietComfort 45
Billy Steele/Engadget
The Bose QuietComfort 45 headphones are back on sale for $249 right now, or 32 percent off their usual price. These are some of our favorite over-ear cans thanks in part to their excellent active noise cancellation and clear, balanced audio. The design isn't as slick as some of our other favorites, but they're comfortable to boot, plus their 24-hour battery life means you'll be able to wear them for long stretches of time without interruption.
The latest AirPods Pro are on sale for $200 for Black Friday. That $50 discount is the most significant we've seen on these buds that just came out a couple of months ago. The new Pros earned a score of 88 from us for their improved sound quality, excellent Transparency Mode and solid active noise cancellation. We also appreciate the addition of the U1 chip inside the buds' wireless charging case, which enables Precision Finding using the Find My app.
The 2021 iPad remains on sale for $270, which is the best price we've seen it. While Apple did just come out with an updated version, that latest model is much more expensive, coming in at $449. The 10.2-inch iPad is still a great option if you want iPadOS but only have so much to spend. We gave it a score of 86 for its solid performance, improved front cameras and excellent battery life.
A four-pack of Apple's AirTags is on sale for $80 right now, which is $20 off their usual price. That also brings the price per tracker down to $20, which is one of the lowest we've seen. These stocking-friendly gadgets make great gifts for iPhone users who want to digitally keep track of their things. They can use the Find My app to check the last known location of their keys, wallet and other belongings, and use their iPhones to be led directly to their stuff with on-screen directions if it's nearby.
Sony's WH-1000XM5 headphones are down to $348 right now, which is the best price we've seen since they came out earlier this year. These are our current favorite wireless headphones, and Sony essentially changed only a few things about the previous WH-1000XM4 to make these cans even better. They have improved noise cancellation and sound quality, plus a slick new design and a solid battery life. We also appreciate their Speak-to-Chat feature and multi-device connectivity.
Both the 4K and HD Chromecasts with Google TV are on sale for Black Friday, coming in at $40 and $18, respectively. These two streamers are essentially the same, expect for the resolution that each support: the higher-end model with stream 4K content, while the other tops out at 1080p. They share a compact design and both come with a handy remote that makes navigating the Google TV interface much easier. Plus, you can speak to the Google Assistant through these dongles, calling about it to search for things to watch, answer questions and more.
Sonos' Black Friday deals include the Sonos One speaker for only $175, which is $44 off its normal price. Sonos gadgets rarely go on sale, much less direct on Sonos' site, so the entire sale is one to consider this Black Friday. The One earned a score of 90 from us when it first came out for its attractive design, excellent audio quality and its support for Amazon's Alexa, the Google Assistant and AirPlay 2. Also included in the sale is the Sonos Arc, one of our favorite soundbars, which is $180 off and down to $719.
Google's best earbuds yet, the Pixel Buds Pro, have dropped to $150, which is $50 less than their usual price. these are the Android-maker's answers to Apple's AirPods Pro, and they are, without a doubt, one of the best pairs of wireless earbuds you can get if you don't have an iPhone. We gave them a score of 87 for their deep, punchy bass, reliable touch controls and wireless charging case.
Elgato's Stream Deck MK.2 has dropped to $120 for Black Friday, which is a new record low. We've recommended various versions of the Stream Deck for a while now as an essential accessory for game streamers, but also a handy peripheral for power users to have, too. The MK.2 has 15 programmable buttons that let you trigger actions like launching an app, muting your mic and more, plus you can truly make it your own with a custom faceplate.
The excellent and already affordable ATH-M20xBT are on sale for $59 for Black Friday, which is a record low. These are our current favorite budget cans thanks to their good sound quality, comfortable design, Bluetooth multi-point connectivity and 60-hour battery life. They may not have as slick of a design as more expensive headphones, or advanced features like noise cancellation, but you can't beat their value.
Samsung's Galaxy Z Flip 4 is on sale for $770 right now. Each iteration of Samsung's foldable phones is better than the last, and the Flip 4 is no different. It has a slick design that neatly folds in half, rendering it small enough to slip into your pocket. Not only do we appreciate its attractive and more durable design, but we also like its improved battery life and the increased number of hands-free applications it supports.
Samsung's latest flagship foldable, the Galaxy Z Fold 4, is $430 off and down to $1,370. It's certainly the most polished Fold Samsung has created, and we gave it a score of 86 for its brighter main screen, upgraded main and telephoto cameras, sleeker hinge and noticeably better battery life.
You can pick up the OnePlus 10 Pro smartphone for only $549 right now, which is the lowest we've seen it. The standout feature of this handset is its remarkably fast charging technology: you can get a full charge in just over a half hour using 80W SUPERVOOC charging. However, US users are capped at 65W SUPERVOOC, but that's still the speediest charging standard available stateside. Otherwise, we also appreciated the 10 Pro's lovely 120Hz display and its fast face-unlock feature.
iRobot's Roomba j7 is on sale for $349 right now, which is the cheapest we've seen it, and you can get the j7+ for $599. This is one of iRobot's latest robo-vacs and it has enhanced obstacle avoidance which lets it navigate around a robot vacuum's arch nemesis: pet poop. It also has 10x the suction power of a standard Roomba, plus support for smart mapping and Alexa and Google Assistant voice control. With the j7+ model, you're also getting a clean base into which the robo-vac will empty its bin after every job.
The latest version of Shark's AI Robot Vaccum has dropped to $299 for Black Friday. This is one of our favorite robo-vacs thanks to its strong suction power, smart mapping feature and the included clean base into which it empties its bin after every job. We also appreciate that the clean base is bagless, so you don't have to regularly buy proprietary bags for it.
August's WiFi smart lock is cheaper than ever at $159 for Black Friday. That's more than $70 off its usual price and a great deal if you're looking for a smart lock that's easy to install over most deadbolts and equally as easy to use. After you put ti on your door, you can use the companion mobile app to remote lock or unlock your home, and you can send limited-time keys to loved ones you who want to have access.
Crucial's MX500 internal drive is down to a new low of $68 for the 1TB version, and you can find discounts on the other configurations, too. We've long recommended this drive for its standard form factor, its sequential reads/write speeds of up to 560/510 MB/s and its AES 256-bit hardware encryption. It also has integrated power loss immunity, which saves all of your work even when there's a power outage.
Jabra's Elite 3 wireless earbuds are on sale for $50, which is the best price we've seen. Considering these buds start out at less than $100, you won't find some advanced features on them like noise cancellation or wireless charging. However, they pack impressive sound quality for the price, along with a comfortable design, reliable onboard controls and good battery life.
Amazon's Echo Show 5 is back on sale for $35 for Black Friday. This has been one of our favorite smart displays for quite some time, primarily because it acts as a great smart alarm clock. It has a 5-inch display that shows the date, time, weather conditions and more, plus it has a handy tap-to-snooze feature. And if you want it to wake you up visually, too, its sunrise alarm will slowly adjust the screen's brightness to wake you up more naturally.
The latest Echo Dot has dropped to $25, and that's the first real discount we've seen since the device came out a few months ago. Amazon added a bigger speaker inside this Echo Dot for improved sound, and it has a new built-in temperature sensor as well. That will come in handy if you have other smart home devices you control with Alexa because, if the temperature sensor reaches a certain level, you can program a routine to, say, start a fan to keep your environment precisely how you like it. The new Dot can also pair with an Eero WiFi system to add up to 1,000 extra square feet of coverage.
Amazon's Kindle Paperwhite has been discounted to $95 for Black Friday. While we consider the Signature Edition to be the best e-reader, period, the standard Paperwhite comes in at a close second. It has a 6.8-inch display with 17 front LEDs for better illumination, plus a water-resistant design, Audible support and a battery that can last weeks on a single charge.
Amazon's most affordable streaming stick is on sale for only $15 right now, which is half off its usual price. This is a good option if you want to upgrade an old, "dumb" TV in your home into a smart one. The Fire TV Stick Lite provides access to Amazon's Fire TV OS, through which you can access services like Netflix, HBO Max, Disney+ and others. The TV Stick Lite supports FHD content, and you can use the included Voice Remote Lite to ask Alexa to show you the content you want to watch. If you want to upgrade a bit to Dolby Atmos, you can get the standard Fire TV Stick for only $5 more.
Amazon has brought back the two for $30 Blink Mini deal for Black Friday. This compact, wired security camera is only meant for indoor use and you'll have to keep it close to an outlet, but it shares all of the basic features with the larger Blink Indoor and Outdoor cameras. It record 1080p video and supports two-way audio, plus it'll send motion alerts to your phone and you can control it via Alexa voice commands.
The original Peloton Bike is $300 off and down to $1,145 for Black Friday. If you're somehow unfamiliar, this is the company's first exercise bike that comes with a built-in screen for taking cycling classes as well as other strength, yoga and bootcamp routines. Also, one of the company's latest gadgets, the Peloton Guide, is on sale for $245, too.
Whether you live in the rapidly drying American West or are aboard the International Space Station for a six-month stint, having enough water to live on is a constant concern. As climate change continues to play havoc on the West’s aquifers, and as humanity pushes further into the solar system, the potable supply challenges we face today will only grow. In their efforts to ensure humanity has enough to drink, some of NASA’s cutting-edge in-orbit water recycling research is coming back down to Earth.
On Earth
In California, for example, the four billion gallons of wastewater generated daily from the state’s homes and businesses, storm drain and roof-connected runoff, makes its way through more than 100,000 miles of sewer lines where it — barring obstructionist fatbergs — eventually ends up at one of the state’s 900 wastewater treatment plants. How that water is processed depends on whether it’s destined for human consumption or non-potable uses like agricultural irrigation, wetland enhancement and groundwater replenishment.
The city of Los Angeles takes a multi-step approach to reclaiming its potable wastewater. Large solids are first strained from incoming fluids using mechanical screens at the treatment plant’s headworks. From there, the wastewater flows into a settling tank where most of the remaining solids are removed — sludged off to anaerobic digesters after sinking to the bottom of the pool. The water is then sent to secondary processing where it is aerated with nitrogen-fixing bacteria before being pushed into another settling, or clarifying, tank. Finally it’s filtered through a tertiary cleaning stage of cationic polymer filters where any remaining solids are removed. By 2035, LA plans to recycle all of its wastewater for potable reuse while Aurora, Colorado, and Atlanta, Georgia, have both already begun augmenting their drinking water supplies with potable reuse.
“There are additional benefits beyond a secure water supply. If you're not relying on importing water, that means there's more water for ecosystems in northern California or Colorado,” Stanford professor William Mitch, said in a recent Stanford Engineering post. “You're cleaning up the wastewater, and therefore you're not discharging wastewater and potential contaminants to California's beaches.”
Wastewater treatment plants in California face a number of challenges, the Water Education Foundation notes, including aging infrastructure; contamination from improperly disposed pharmaceuticals and pesticide runoff; population demands combined with reduced flows due to climate change-induced drought. However their ability to deliver pristine water actually outperforms nature.
“We expected that potable reuse waters would be cleaner, in some cases, than conventional drinking water due to the fact that much more extensive treatment is conducted for them,” Mitch argued in an October study in Nature Sustainability. “But we were surprised that in some cases the quality of the reuse water, particularly the reverse-osmosis-treated waters, was comparable to groundwater, which is traditionally considered the highest quality water.”
The solids pulled from wastewater are also heavily treated during recycling. The junk from the first stage is sent to local landfills, while the biological solids strained from the second and third stages are sent to anaerobic chambers where their decomposition generates biogas that can be burned for electrical production and converted to nitrogen-rich fertilizer for agricultural use.
New York, for example, produces 22,746 tons of wastewater sludge per day from its 1,200-plus statewide wastewater treatment plants (WWTPs). However, less than a tenth of plants (116 specifically) actually use that sludge to produce biogas, per a 2021 report from the Rockefeller Institute for Government, and is “mainly utilized to fuel the facilities and for the combined heat and power generation of the WWTPs.”
“Increasing pressures on water resources have led to greater water scarcity and a growing demand for alternative water sources,” the Environmental Protection Agency points out. “Onsite non-potable water reuse is one solution that can help communities reclaim, recycle, and then reuse water for non-drinking water purposes.”
In Orbit
Aboard the ISS, astronauts have even less leeway in their water use on account of the station being a closed-loop system isolated in space. Also because SpaceX charges $2,500 per pound of cargo (after the first 440 pounds, for which it charges $1.1 million) to send into orbit on one of its rockets — and liquid water is heavy.
ESA
While the ISS does get the occasional shipment of water in the form of 90-pound duffle bag-shaped Contingency Water Containers to replace what’s invariably lost to space, its inhabitants rely on the complicated web of levers and tubes you see above and below to reclaim every dram of moisture possible and process it into potability. The station’s Water Processing Assembly can produce up to 36 gallons of drinkable water every day from the crew’s sweat, breath and urine. When it was installed in 2008, the station’s water delivery needs dropped by around 1,600 gallons, weighing 15,960 pounds. It works in conjunction with the Urine Processor Assembly (UPA), Oxygen Generation Assembly (OGA), Sabatier reactor (which recombines free oxygen and hydrogen split by the OGA back into water) and Regenerative Environmental Control and Life Support Systems (ECLSS) systems to maintain the station’s “water balance” and supply American astronauts with a minimum of 2.5 liters of water each day. Cosmonauts in the Russian segment of the ISS rely on a separate filtration system that only collects shower runoff and condensation and therefore require more regular water deliveries to keep their tanks topped off.
ESA
In 2017, NASA upgraded the WPA with a new reverse-osmosis filter in order to, “reduce the resupply mass of the WPA Multi-filtration Bed and improved catalyst for the WPA Catalytic Reactor to reduce the operational temperature and pressure,” the agency announced that year. “Though the WRS [water recovery system] has performed well since operations began in November 2008, several modifications have been identified to improve the overall system performance. These modifications aim to reduce resupply and improve overall system reliability, which is beneficial for the ongoing ISS mission as well as for future NASA manned missions.”
One such improvement is the upgraded Brine Processor Assembly (BPA) delivered in 2021, a filter that sieves more salt out of astronaut urine to produce more reclaimed water than its predecessor. But there is still a long way to go before we can securely transport crews through interplanetary space. NASA notes that the WPA that got delivered in 2008 was originally rated to recover 85 percent of the water in crew urine though its performance has since improved to 87 percent.
NASA
“To leave low-Earth orbit and enable long-duration exploration far from Earth, we need to close the water loop,” Caitlin Meyer, deputy project manager for Advanced Exploration Systems Life Support Systems at NASA’s Johnson Space Center in Houston, added. “Current urine water recovery systems utilize distillation, which produces a brine. The [BPA] will accept that water-containing effluent and extract the remaining water.”
When the post-processed urine is then mixed with reclaimed condensation and runs through the WPA again, “our overall water recovery is about 93.5 percent,” Layne Carter, International Space Station Water Subsystem Manager at Marshall, said in 2021. To safely get to Mars, NASA figures it needs a reclamation rate of 98 percent or better.
But even if the ISS’s current state-of-the-art recycling technology isn’t quite enough to get us to Mars, it’s already making an impact planetside. For example, in the early 2000’s the Argonide company developed a “NanoCeram” nanofiber water filtration system with NASA small business funding support. The filter uses positively charged microscopic alumina fibers to remove virtually all contaminants without overly restricting flow rate, eventually spawning the Oas shower from Orbital Systems.
“The shower starts with less than a gallon of water and circulates it at a rate of three to four gallons per minute, more flow than most conventional showers provide,” NASA noted last July. “The system checks water quality 20 times per second, and the most highly polluted water, such as shampoo rinse, is jettisoned and replaced. The rest goes through the NanoCeram filter and then is bombarded with ultraviolet light before being recirculated.” According to the Swedish Institute for Communicable Disease Control, the resulting water is cleaner than tap.
Twitter's Brussels office is no more, according to reports, which could make it more difficult for the company to adhere to new European Union regulations regarding content moderation. The number of people employed at the office dropped from six to two after new owner Elon Musk cut the workforce in half. The remaining executives, Julia Mozer and Dario La Nasa, left Twitter last week, according to the Financial Times — just as Musk told employees to commit to his vision for a "hardcore" Twitter 2.0 or leave.
Mozer and La Nasa oversaw public policy for Twitter in Europe. They were in charge of efforts to make sure Twitter complies with the EU's disinformation code as well as the Digital Services Act. The DSA came into force last week and will apply to companies starting in February 2024. It gives EU governments more power over how platforms moderate content and when tech companies have to take down illegal content. Platforms will need to be transparent about the reasons for content moderation decisions. Affected users will have the right to challenge moderation decisions if their content is removed or access to it is restricted.
If Twitter fails to comply with the DSA's rules, it faces potentially heavy penalties. Regulators could fine Twitter up to six percent of its global turnover or even ban the platform. EU internal market commissioner Thierry Breton has warned Musk that Twitter needs to abide by the bloc's content regulations.
Twitter no longer has a communications department that can be asked for comment. Musk said early Thursday that the "general idea" is to limit moderation rules to "illegal content." Minutes earlier, he asked users to reply to him with "anything that Twitter needs to address" in terms of child exploitation on the platform. Regulations about which content is legal can vary significantly by jurisdiction (Germany has fairly strict social media edicts, for instance), and having fewer staff dedicated to ensuring Twitter plays by the rules could make it more difficult for the company to do so.
“I am concerned about the news of firing such a vast amount of staff of Twitter in Europe,” Věra Jourová, an EU vice president who is in charge of the bloc's disinformation code, told the Financial Times. “If you want to effectively detect and take action against disinformation and propaganda, this requires resources. Especially in the context of Russian disinformation warfare, I expect Twitter to fully respect the EU law and honor its commitments."
Meanwhile, several Democratic senators have asked the Federal Trade Commission to determine whether the company has broken consumer protection laws or violated a consent decree with the agency. Among other things, the latter requires Twitter to review new features for potential privacy issues. Earlier this month, it was reported that Twitter engineers have to "self-certify" that they're complying with FTC rules and other laws. The FTC recently said it's “tracking recent developments at Twitter with deep concern.”
For those unfamiliar with the details of the expansive work of fiction of Harry Potter, it did introduce a few ideas that have really stuck in the collective conscious. Besides containing one of the few instances of time travel done properly and introducing a fairly comprehensive magical physics system, the one thing specifically that seems to have had the most impact around here is the Weasley family clock, which shows the location of several of the characters. We’ve seen these built before in non-magical ways, but this latest build seeks to drop the price tag on one substantially.
To do this, the build relies on several low-cost cloud computing solutions and smartphone apps to solve the location-finding problem. The app is called OwnTracks and is an open-source location tracker which can report data to any of a number of services. [Simon] sends the MQTT data to a cloud-based solution called HiveMQCloud, but you could send it anywhere in principle. With the location tracking handled, he turns to some very low-cost Arduinos to control the stepper motors which point the clock hands to the correct locations on the face.
While the build does rely on a 3D printer for some of the internal workings of the clock, this does bring the cost down substantially when compared to other options. Especially when compared to this Weasley family clock which was built into a much larger piece of timekeeping equipment, having an option for a lower-cost location-tracking clock face like this one is certainly welcome.
If you want smart temperature controls without breaking the bank, you may want to look at the Amazon Smart Thermostat, on sale right now for $42. That's 30 percent off its retail price of $60, matching an all-time low. Considering the thermostat is much cheaper than its big-name competitors even when it isn't on sale, this Black Friday deal provides an unparalleled bang for your buck.
Amazon's thermostat lacks some bells and whistles. For example, it doesn't have a built-in microphone and speaker, or support remote sensors. It also doesn't work with Google Assistant or Apple HomeKit. But if Alexa is already your smart home platform of choice, Amazon's thermostat is a dirt-cheap option that works with most existing 24V HVACs (the most common for residential systems).
For an entry-level offering, it offers a surprisingly sleek and modern design. Its rounded-rectangle shape is similar to ecobee's offerings, while its color scheme mirrors Google Nest products.
Amazon partnered with Honeywell Home for the thermostat, which lets you create routines, set temperatures manually (including remotely), or lets Alexa handle it for you. Additionally, it's Energy Star-certified, and Amazon claims it can save you around $50 on your power bills each year. After signing up, Amazon will even send you an email with details about available rebates from local energy providers.
Installation should be easy, but Amazon includes a "check compatibility" tutorial on the product page that guides you through various details to ensure it will work. One crucial point to check is whether your existing thermostat setup has a C-Wire. If not, you'll want to choose the bundle that includes an adapter.
It's easy to drop hundreds on a good pair of headphones, especially now when most of them are at least cheaper than they usually are. But it's not necessary to spend so much on a good pair of cans. Earlier this year, Audio-Technica introduced the $79 ATH-M20xBT, a wireless version of the original M20x, and they quickly became our favorite pair of budget-friendly wireless headphones. For Black Friday, these cans are cheaper than ever at just $59, giving you an opportunity to grab them at the lowest price we've seen.
The ATH-M20xBT may not have advanced features like active noise cancellation, but they have a lot going for them regardless. We like their comfortable design, even if it isn't as refined as that of the higher-end M50x. Their audio quality is good, and they also come with 40mm drivers for improved low-frequency performance. We also like their onboard, physical-button controls, which let you control calls, volume and music playback more easily.
Arguably the biggest feature of these headphones is their Bluetooth connectivity, which lets you use them wirelessly. But Audio-Technica also added multi-point pairing, so you can use them with more than one device at once. This is becoming a standard feature among the best headphones out there, so it's reassuring to see it come to a budget-friendly pair like this. The ATH-M20xBT also have a killer, 60-hour battery life, and they support fast-charge via USB-C, providing three hours of listening time after only 10 minutes of being plugged in. So while they might not be as slick as some of our other favorite wireless headphones, these cans offer a ton of value for the price — and even more when they're on sale like this.
Amazon's latest entry-level Kindle has received its first discount in time for Black Friday. The company is selling the 2022 ad-supported Kindle for $85, or $15 below the official price. That makes it tempting if you're planning a gift for the bookworm in your life, or have just been waiting for a deal to treat yourself to Amazon's most affordable e-reader.
The refreshed starter Kindle is a major upgrade. The centerpiece is a 6-inch 300 pixels-per-inch display that's much sharper than the 167PPI screen of its predecessor, making text that much easier on the eyes. A longer six-week battery life, USB-C charging and doubled storage (16GB) also make it decidedly more practical than the previous model. You might not need more than this to have your dream e-reader, although you may want to pay extra to avoid lockscreen ads.
If you do need more, though, Amazon's ongoing Black Friday sale gives you options. Most notably, the Kindle Paperwhite is still available for $95. You won't have as much storage for that money (you'll need to spend $100), but you will get a larger 6.8-inch display, bath-friendly water resistance and an adjustable warm light. If you don't need those perks or just want the smallest reader in the lineup, though, the base Kindle is still easy to justify.
The Russo brothers are creating a series for Amazon based on the story of how FTX, which was once one of the most well-known crypto exchanges, met such a swift and scandalous end. According to Variety, Amazon has approved a limited series adaptation with eight episodes and is looking to start production by spring next year. David Weil, who previously worked with the Russo brothers in their Prime Video series Citadel, will write and executive produce the pilot episode. Meanwhile, Anthony and Joe Russo, known for directing four Marvel Cinematic Universe movies, are reportedly in talks of directing on top of serving as the show's executive producers.
FTX filed for bankruptcy last week after a series of events ultimately led to its collapse in a short amount of time. The exchange's FTT tokens had plummeted in value earlier this month after rival exchange Binance announced that it was going to sell its remaining FTTs due to "recent revelations." A few days before Binance decided to liquidate all its FTTs, CoinDesk had reported that Alameda Research, the trading firm that was founded by then-FTX CEO Sam Bankman-Fried, was mostly backed by FTT tokens. "The situation adds to evidence that the ties between FTX and Alameda are unusually close," CoinDesk wrote. Alameda had reportedly been having financial issues and was allegedly using FTX customers' deposits to pay debts.
Smaller investors and ordinary customers also sought to get out upon smelling trouble in the air and submitted requests for withdrawals, which caused a liquidity issue. Binance initially agreed to bail out FTX by buying it but ultimately backed out of the deal. After that, FTX filed for bankruptcy, and Bankman-Fried resigned as CEO. There's a lot more to the story, including the mystery of where billions of dollars of missing or stolen funds had gone, that the Russo brothers could include in their show.
It's still unclear what source material the Russos are planning to use, but Variety says the show could be based on "insider reporting" by journalists who've been investigating the FTX scandal. They're also reportedly in talks with multiple Marvel actors to play key roles in the series. Before Amazon confirmed that it was working on a show based on FTX, Deadline reported that Apple was close to signing a seven-figure deal for the rights on a book about Bankman-Fried and the crypto exchange that's being written by Michael Lewis. That's the same author behind Moneyball, The Big Short and The Blind Side. Unlike Amazon, Apple is reportedly planning to turn Lewis' book into a feature film.
