Electric vehicle startup Rivian announced on Thursday that it has settled a lawsuit with some of its investors. The company continues to deny allegations of making “materially untrue” statements during its inial public offering but says it agreed to pay $250 million to clear itself of distractions as it focuses on building its next EV, the mass-market R2, which is due next year.

Rivian was first sued by a shareholder in 2022 over claims that the startup knew it would cost far more for it to build each R1T electric truck and R1S electric SUV than the advertised $67,500 and $70,000 prices, respectively. A big surprise price increase would tarnish the nascent automaker’s reputation, the lawsuit claimed, and could lead to many of the almost 56,000 pre-orders being canceled.

Just a few months after its November 2021 IPO, the company had indeed issued a hefty price hike: $79,500 for the R1T and $84,500 for the R1S SUV. After an outcry, the company said it would honor the original price for its existing preorders. By that point, though, the damage was done, and more than a third of the company’s value was erased within a few days, the lawsuit alleged.

The pandemic proved that a lot of us can do our jobs just fine out of the office. Nevertheless, companies continue to push for workers to return to their cubicles—whether in a hybrid arrangement, or five-days-a-week mandatory attendance. In both cases, many companies are looking for ways to hold employees accountable: Since many of our jobs can be done anywhere with an internet connection, if your boss doesn’t have eyes on you, it’s not always easy to tell where you’re working from.

Perhaps your company has rolled out initiatives meant to encourage office attendance. Maybe your boss counts your badge swipes, to ensure that you’re meeting your weekly in-office quota, or you are obligated to attend in-person meetings. But it’s not just the companies themselves that are working on these kinds of measures. Even Microsoft is trying to make it harder for remote employees to continue working from where they want to.

How Teams will track where you’re working from

As spotted by Tom’s Guide, Microsoft Teams will roll out an update in December that will have the option to report whether or not you’re working from your company’s office. The update notes are sparse on details, but include the following: “When users connect to their organization’s [wifi], Teams will soon be able to automatically update their work location to reflect the building they’re working from. This feature will be off by default. Tenant admins will decide whether to enable it and require end-users to opt-in.”

The language suggests that Microsoft intends for this feature to be focused more on helping workers locate fellow employees in large office complexes, and less on snitching on employees working from home when they shouldn’t be. That’s fair enough: If I worked for a company with multiple buildings on campus, it’d be helpful to know where someone I needed to talk to happened to be working that day.

But let’s be real. This feature is also going to be used by companies to track their employees, and ensure that they’re working from where they’re supposed to be working from. Your boss can take a look at your Teams status at any time, and if it doesn’t report you’re working from one of the company’s buildings, they’ll know you’re not in the office. No, the feature won’t be on by default, but if your company wants to, your IT can switch it on, and require that you enable it on your end as well.

As someone who has worked remotely for most of my professional career, I find the return-to-office mandates generally silly. I understand there are jobs that cannot be done remotely, and aspects of others that are made better by in-person collaboration. But if the vast majority of your work is done on a laptop connected to the internet, it makes no sense for you to be forced to work from an office. It also seems demoralizing to treat employees like children, tracking their whereabouts to ensure they’re doing their jobs from a pre-approved location. If you’re getting your work done, who cares where that work is happening?

The federal government has released a list of all of the entities helping to pay for President Trump’s lavish White House ballroom, according to reporting by Business Insider. Big tech is all over this thing, with companies like Amazon, Apple, Google, Meta and Microsoft all shelling out cash to fund the 90,000-square-foot ballroom.

It’s not just big tech. Defense firms are also helping to pony the bill here. Companies like Lockheed Martin and Palintir are sending some cash, as are random billionaires like the Winklevoss twins and Domino Sugar magnate José Fanjul. The list reads like a who’s who of the ultra wealthy and connected. 

As we all know, giant corporations and billionaires are kind and selfless, but what if just this one time they want something in return for their largesse? Columbia professor of law Richard Briffault told Time that most of these donors have done “significant” business with the federal government, raising ethical concerns.

“I doubt it’s a literal quid-pro-quo, but it’s probably more like ‘if you give this, I will look favorably upon you.’ Or maybe more like, ‘if you don’t give this, after you’ve been asked, I won’t [look favorably upon you],” Briffault said. “It’s greasing the system by making contributions, and in some ways, his leaning on them for contributions is quasi-coercive.”

Noah Bookbinder, CEO and President of ethics watchdog organization Citizens for Responsibility and Ethics in Washington said the whole thing is “extraordinarily unusual, deeply disturbing and does have tremendous ethics implications.” He also said that “Donald Trump has made very clear over the years that he does appreciate people paying tribute to him, and he does tend to do things that benefit those people.”

Trump has been personally woo-ing these potential financiers. There was a fundraising dinner in the East Room last week that included representatives of several of the aforementioned companies. The dinner was billed as an event to “Establish the Magnificent White House Ballroom,” according to the Wall Street Journal. The outlet also reported that Trump has held meetings at the White House and at his club in Virginia to raise money for the project.

It’s worth noting that this isn’t the first time big tech companies have banded together to pay tribute to Trump. Most of the aforementioned companies helped pay for his inauguration and, heck, Apple CEO Tim Cook gave Trump an actual 24K gold statue for some reason.

The construction of this glorious ballroom we all most definitely want has already been at the heart of several controversies. Americans were recently surprised to find that the East Wing of the White House had been completely demolished, despite the president previously promising the ballroom would not even touch the actual property.

In any event, we’ll soon be able to watch live feeds of the ultra rich dancing the night away to the Village People or whatever, which is sure to solve all of our problems. In unrelated news, food stamps are likely to run out next week for around 41 million Americans and beef now averages $10 a pound.

There are three species of bats that eat birds. We know that because we have found feathers and other avian remains in their feces. What we didn’t know was how exactly they hunt birds, which are quite a bit heavier, faster, and stronger than the insects bats usually dine on.

To find out, Elena Tena, a biologist at Doñana Biological Station in Seville, Spain, and her colleagues attached ultra-light sensors to Nyctalus Iasiopterus, the largest bats in Europe. What they found was jaw-droppingly brutal.

Inconspicuous interceptors

Nyctalus Iasiopterus, otherwise known as greater noctule bats, have a wingspan of about 45 centimeters. They have reddish-brown or chestnut fur with a slightly paler underside, and usually weigh around 40 to 60 grams. Despite that minimal weight, they are the largest of the three bat species known to eat birds, so the key challenge in getting a glimpse into the way they hunt was finding sensors light enough to not impede the bats’ flight.

Automattic has filed counterclaims against WP Engine in a lawsuit the hosting company initiated in October 2024. The counterclaims accuse WP Engine of trademark infringement and deceptive marketing practices. After private equity firm Silver Lake invested $250 million in WP Engine, the hosting company began calling itself “The WordPress Technology Company” and allowed partners to refer to it as “WordPress Engine,” the lawsuit says. WP Engine also launched products named “Core WordPress” and “Headless WordPress.”

The counterclaims allege that WP Engine promised to commit 5% of its resources to the WordPress ecosystem but failed to keep those promises. Automattic contends that WP Engine engaged in trademark violations to avoid licensing fees that would have affected the company’s earnings and valuation. Silver Lake sought to sell WP Engine at a $2 billion valuation but could not find a buyer. The filing notes that potential buyers included Automattic. The counterclaims also assert that WP Engine degraded product quality and removed essential features to reduce costs during this period.

Though it brings me no pleasure, it’s once again time to discuss the viral apps Tea and TeaOnHer. You may remember them from the summer, when Tea—where women could anonymously rate and discuss men under the pretense of helping each other safely navigate dating—was the target of data breaches that exposed users’ personal information. From there, an app called TeaOnHer was launched for men and Tea faced a class action from users who were upset about their private data being easily accessible to hackers. Whether you remember them or not, they’re gone now—sort of. Apple has yanked them from the App Store.

The App Store removal of Tea and TeaOnHer

Tea was around for about two years before it unexpectedly went viral in July, which led to at least two distinct data breaches, the second of which occurred when a data expert discovered that not only were some users’ pictures stored in an unsecured manner, but some private DMs were, too.

Part of the reason the app went so viral in the first place was that a lot of people were uncomfortable with its premise. It functioned like Yelp, but instead of reviewing businesses, women could review men. The men had no recourse or due process; they couldn’t even access the app, let alone respond to anything said about them. (Women were granted access by uploading ID photos or verification selfies and it was the trove of ID photos that was originally hacked and leaked.)

Some people found that unfair and others saw an opportunity to cash in on the discontent. TeaOnHer, an app with the same premise but aimed at men, hit the App Store about two weeks after the Tea hack. The privacy discourse continued, but both apps remained up in the Apple App Store anyway. Until now.

Apple confirmed to TechCrunch that the apps were pulled because they failed to meet the company’s requirements for user privacy and content moderation. Sure enough, if you search the apps on the App Store, nothing comes up. Well, except a bunch of imposters looking to make the most of Tea and TOH’s absence. Something called “Tea On Her & Him – Overheard” is the second-most-downloaded free app in the Lifestyle category right now.

Can you still use Tea?

Tea hasn’t been pulled from Google Play yet, so you can still access it on Android. Moreover, if you already had Tea on your iPhone, it still functions—for now.

When the DM breach was made public over the summer, Tea responded by shutting down DMs and making that clear within the app. Over the course of the news cycle at the time, the app posted public communications to its Instagram page. Within the app and on its social media, there is no mention of the App Store removal, but a rep did email me this: “We are aware that the Tea App has been removed from the App Store and we are working to address Apple’s feedback. We know what this app means to our more than six million users and remain deeply committed to our mission of helping women navigate dating with confidence.”

Stop me if you’ve heard this one before: YouTube TV may lose a provider’s content because a deadline is approaching without a deal in place. This time, the media company is Disney. It’s warning (via Variety) that its networks could soon go dark on Google’s streaming service.

The two sides are negotiating ahead of an October 30 midnight ET deadline. If they can’t agree by then, all Disney content will disappear from YouTube TV. That includes (among others) all ESPN channels, local ABC stations, ABC News, FX, NatGeo, Disney Channel and Freeform. A YouTube spokesperson told Variety that if that should happen for “an extended period of time,” subscribers will receive a $20 credit.

One aspect of these battles is finger-pointing as each side tries to leverage public perception. Disney says YouTube is trying to muscle the mouse into paying below market value. Meanwhile, YouTube claims Disney is “proposing costly economic terms” that could lead to even higher subscription fees. YouTube TV launched at $35 per month in 2017 and now costs a whopping $83 monthly.

If recent history is any indication, you can expect the dire warnings of content removal to continue until they strike a deal at the last second. That already happened several times this year.

In February, YouTube TV and Paramount had that dance. Google’s streaming network and Fox came to a renewal deal in August after repeated content-removal warnings. YouTube TV and NBCUniversal did the thing earlier this month. However, in that case, the streaming service dropped Univision and other TelevisaUnivision networks, so tidy deals aren’t inevitable. Time will tell how this one plays out, but it’s hard to imagine either side here wanting to play chicken past the October 30 deadline.

Amazon is offering a hefty discount on the Ring Battery Doorbell Plus. The video doorbell has dropped from its regular price of $150 to $80 in a limited-time deal.

That’s a discount of 47 percent for this particular model. It also matches the record-low price we saw for the Ring Battery Doorbell Plus during the Prime Day event earlier this month.

The Ring Battery Doorbell Plus has a more expanded field-of-view compared with earlier models, allowing for head-to-toe views of whoever’s at your doorstep. There’s support for color night vision, along with motion detection and the ability to set up privacy zones.

Amazon says the Battery Doorbell Plus is easy to set up using the Ring app and mounting tools. The company added that there’s a quick release system for the battery pack, so you can take it inside for recharging without having to unscrew a cover.

Naturally, the device is connected to the Alexa smart home ecosystem, so you’ll be able to receive motion alerts on compatible Echo devices or see a live view of the camera’s feed on an Echo Show, Fire TV or Fire Tablet. You’ll be able to chat to whoever’s at the door too, via the doorbell’s two-way communication system.

A Ring Home subscription is required for you to receive package alerts — this feature will let you know when the doorbell’s camera detects a package within a particular zone. The subscription also includes the option to save recorded videos for up to 180 days, among other features.

Intel’s tick-tock development cadence will not return. CEO Lip-Bu Tan said during the company’s Q3 2025 earnings call that the 18A process node will be a “long-lived node” powering at least three generations of client and server products. Intel reported its first profit in nearly two years, aided by financial support from Nvidia, Softbank, and the US government.

The company faces chip shortages that will peak in the first quarter of next year. CFO David Zinsner said Intel is prioritizing AI server chips over consumer processors. Intel will launch only one Panther Lake SKU this year and roll out others in 2026. Zinsner called Panther Lake “pretty expensive” and said Intel will push Lunar Lake chips “in at least the first half of the year.”

In 1812, Napoleon Bonaparte led a disastrous military campaign into Moscow. The death toll was devastating: Out of some 615,000 men, only about 110,000 survivors returned. (Napoleon abandoned his army in early December to return home on a sled.) Roughly 100,000 of the casualties died in battle, while as many as 300,000 perished from a combination of the bitter cold of Russia’s notoriously harsh winter, starvation, and disease.

Scholars have debated precisely what kinds of diseases ravaged Napoleon’s troops. New DNA analysis of some soldiers’ remains has revealed the presence of two pathogens in particular, according to a new paper published in the journal Current Biology. The first is Salmonella enterica, which causes paratyphoid fever; the second is Borrelia recurrentis, which is transmitted by body lice and causes relapsing fever. (A preprint of the paper appeared on bioaRxiv in July.)

“It’s very exciting to use a technology we have today to detect and diagnose something that was buried for 200 years,” said co-author Nicolás Rascovan of the Institut Pasteur. “Accessing the genomic data of the pathogens that circulated in historical populations helps us to understand how infectious diseases evolved, spread, and disappeared over time and to identify the social or environmental contexts that played a part in these developments. This information provides us with valuable insights to better understand and tackle infectious diseases today.”

Netflix is reportedly closing its Boss Fight Entertainment game development studio, according to various LinkedIn posts by staffers. The streaming giant bought the company back in 2022 and it has been responsible for games like Squid Game: Unleashed and the interactive narrative Netflix Stories.

This is relatively surprising, as Squid Game: Unleashed was something of a hit. It launched alongside season two of the show and has amassed over ten million downloads on the Google Play Store alone, according to reporting by Mobilegamer. It recently received a major software update coinciding with season three of the show.

Boss Fight Entertainment has around 80 staffers. It’s unclear if they’ll be laid off or shuffled somewhere else within Netflix’s gaming division. Engadget has reached out to Netflix and will update this post when we hear back.

Several designers at the company have expressed regret that we won’t see what it had planned for the future. “It’s infuriating that the world will never see some of the stuff that was shuffled away behind the scenes,” wrote design director Damion Schubert on LinkedIn.

This is the second studio that Netflix has chased out the door in the past year. It shut down its AAA game studio Team Blue, which had attracted developers from Blizzard, Bungie and Sony Santa Monica. We never even got to find out what the team was working on.

Investing in a smart thermostat won’t just keep your home comfortable — it also can help you save money on energy bills and reduce your carbon footprint. By automating scheduling and learning preferred temperatures, smart thermostats conserve energy and make your home more comfortable. The 2022 Ecobee Smart Thermostat Premium might not be the newest option on the market, but to this day, it receives consistently excellent ratings, and right now, it’s $198.99 (originally $249.99) on Walmart, marking its lowest price ever according to price trackers.

Ecobee is known for having one of the strongest privacy policies in the smart-home space. The company doesn’t sell personal information, collects minimal data, prioritizes user ownership of data, and supports 2FA for added protection. When paired with Ecobee SmartSensors and an Ecobee SmartCamera, it can also double as a home security hub. 

This model, which earned a PCMag Editor’s Choice award, comes with a smart sensor that balances temperatures in your home using occupancy detection. While the thermostat is smaller than its predecessor, it has a larger four-inch full-color touchscreen that’s bright enough to read from across the room. 

It has a built-in speaker and mic that’s compatible with a wide variety of smart-home ecosystems, letting you listen to music, get news or weather updates, change thermostat settings, and check the temperature in rooms with sensors. You can even monitor air quality with alerts and tips on indoor humidity levels and whether the air quality is clean or poor. All of this is accessible from the Ecobee mobile app.

While the price is higher than a basic smart thermostat, if you want lower energy costs while benefitting from features like measuring air quality, an integrated voice assistant that doubles as a speaker, and remote sensors, the eco-friendly Ecobee Smart Thermostat Premium is a strong choice that can help you save money in the long-run and make your home more comfortable.

High-resolution audio on the go isn’t very convenient. It typically involves wired headphones and a DAC (digital-to-analog converter) of some kind, plus your phone or another device to access files or a streaming service. All of this is necessary since Bluetooth compresses an audio signal by design, to allow for low-latency transmission and minimize battery draw. Simply put, wireless headphones haven’t been able to meet the demands of lossless audio, but Sennheiser has come the closest to fulfilling the dream with its HDB 630 ($500). 

Thanks to redesigned drivers, a new acoustic platform and a dongle, the company offers up to 24-bit/96kHz audio on the HDB 630 — depending on your configuration. You also get above average active noise cancellation (ANC), a highly customizable EQ, shockingly long battery life and advanced features to fine-tune the headphones to your liking. For some, the best possible sound is still only found on pricey setups and open-back headphones. For everyone else, Sennheiser has provided a taste of the audiophile life in a much more portable package. 

Design

Sennheiser says the HDB 630 “inherited” the same chassis from its Momentum 4 headphones. That’s unfortunate because my biggest complaint with that older model’s redesign is how cheap it looked compared to previous entries in the Momentum line. The HDB 630 suffers the same fate, although the splash of silver on the headband and yokes helps things a bit. Simply put, these don’t look like a set of $500 headphones, and since they’re $150 more than their predecessor was at launch, they really should have a more premium appearance. 

The outside of the right ear cup is still a touch panel where you can swipe, tap and even pinch to control the HDB 630. I don’t recall another set of headphones with a pinch gesture, and I’m still not convinced it’s warranted. The action is used to enable an Adaptive ANC adjustment that allows you to dial in the amount of noise blocking you need. After the pinch, sliding a single finger forwards and backwards fine tunes the mix of ANC and transparency mode. It’s a nice option to have on the headphones themselves, I just think a triple tap to activate it would be easier to master — and remember. 

The only other button on the HDB 630 is for power and Bluetooth pairing. Unless you’re frequently connecting these headphones to a new device, you might not be reaching for this control very often. That’s because the HDB 630 goes into standby mode when you take them off before powering down completely after 15 minutes of inactivity. You can extend that window to 30 or 60 minutes if you prefer. And if the headphones still have battery left, you can return to active mode by simply putting them back on your head. 

Sennheiser is betting you’ll use the HDB 630 for long listening sessions, so it outfitted these headphones with soft ear pads and a well-cushioned headband. The clamping force is adequate for a proper ANC seal, but never becomes a burden. And despite being around 20 grams heavier than the Momentum 4, this model still feels balanced and doesn’t weigh you down. 

Sound quality

Billy Steele for Engadget

While the overall design may be familiar, the sound platform for the HDB 630 is completely new. 42mm drivers offer what Sennheiser says is “neutral sound with lifelike mids, stunning detail and a wide soundstage.” In order to deliver sound quality that’s as close to open-back headphones as possible, the company overhauled the entire acoustic system, from the drivers to the baffle’s transparent mesh, in the name of balance and clarity. And since audiophile headphones typically require a dedicated external amplifier to achieve their full potential, Sennheiser included a BTD 700 USB-C dongle for high-resolution wireless audio transmission. 

When I first put the HDB 630 on, I thought the audio quality was good but not great. Listening over the standard definition SBC codec produced decent results, but it wasn’t anything to write home about. Once I connected to the BTD 700 dongle and unlocked 16-bit/48kHz tunes from Apple Music, though, these headphones really started to impress. 

As good as they are, the HDB 630 may not be for everyone. That “neutral” stock tuning places high emphasis on the midrange, so you’ll likely need to make some adjustments to get the bass performance you crave from rock, electronic, hip-hop and other genres driven by low-end tone. While I concede the neutral base is a great starting point, and the HDB 630 does indeed showcase “stunning detail,” I’d argue Sennheiser’s promise of “a wide soundstage” doesn’t always hold true. 

These headphones are at their best with more immersive content, like the TRON: Ares soundtrack from Nine Inch Nails. After a slight adjustment, the electronic score had the booming bass it needed, offering driving beats that nearly rattled my brain. All that was layered with rich synths and Trent Reznor’s iconic vocals. The texture and distortion in the instruments came through in greater detail too, something that’s not as apparent on other headphones and earbuds. 

Switch over to Thrice’s Horizons/West and the HDB 630 is a different story. Transitioning from synth-heavy electronic music to a genre like rock causes these headphones to lose some of the immersive character they are capable of delivering. You still get absurd clarity and detail, particularly in Teppei Teranishi’s guitar riffs, but the music sounds slightly flatter and a little less energetic. It’s not bad by any means, but some genres won’t envelope you as much as others do. 

You can also use the HDB 630 wired over USB-C for lossless-quality audio. Since a number of competitors also do this, I dedicated the bulk of my testing to see if Sennheiser’s wireless dongle is meaningfully different. Of course, I did my due diligence and tested the wired configuration a few times, and it should come as no surprise that the HDB 630 sounds just as good in that setup. 

Software, features and accessories

Billy Steele for Engadget

As I mentioned, the HDB 630 comes with Sennheiser’s BTD 700 Bluetooth USB dongle. This enables higher quality streaming than you’ll natively get from most devices. With the BTD 700, you can expect aptX Adaptive and aptX Lossless listening up at rates to 24-bit/96kHz. The dongle also has a 30ms low-latency gaming mode, (supposedly) enhanced call performance and Auracast support for streaming to multiple headphones or speakers. The BTD 700 has a USB-C connector, but it comes with a USB-A adapter if you need it. This typically costs $60 if you buy it on its own, and since you need it to unlock the HDB 630’s full potential, it’s great to see it included in the box. 

The HDB 630’s settings and features are accessible in the Sennheiser Smart Control Plus app. And for this model, the company is offering a lot more customization than it does on the Accentum or Momentum headphones. First, the EQ editing options are more robust thanks to a parametric equalizer, which allows you to get a lot more detailed with your custom presets. For example, I was able to add the low-end tone I feel is missing from the stock tuning for those metal, rock and hip-hop tracks I mentioned before. And unlike a lot of headphone apps, adjusting the EQ actually improves the sound instead of just muddying things further. 

Another sound-related addition for the HDB 630 is Crossfeed. This allows you to blend the left and right channels so that it seems like you’re listening to speakers instead of headphones. Unfortunately, you only get two options here — Low and High — but the effect certainly enhances the sonic profile of the HDB 630 at both settings. 

Despite the BTD 700 dongle’s Mac and Windows compatibility, there’s no desktop version of the Smart Control Plus app. This means you’ll have to change all of your settings with the HDB 630 through your phone before you pair it with both the dongle and your computer. It would be nice if you could make EQ adjustments, create new presets and even change Crossfeed levels without having to reconnect to another device. This also means you can’t be connected to the BTD 700 and both your phone and your computer, since the dongle takes one of the two available multipoint Bluetooth slots.

Active noise cancellation and call quality

Billy Steele for Engadget

When it comes to ANC performance, I’m not entirely sure that the HDB 630 is better than the Momentum 4. But that’s okay. That previous model brought a significant improvement compared to Sennheiser’s older wireless headphones and the ANC is still quite good here. In fact, it was robust enough to block my family’s voices during their calls while I worked from home, and since most headphones struggle with this, that’s no mean feat. 

Sennheiser says the BTD 700 dongle will give you improved voice performance over the headphones alone. Specifically, the accessory should provide extended range, clearer voice pickup and, according to the company, “uninterrupted” calls. In my recorded samples, I think the headphones themselves sounded slightly better than when I captured my voice while connected to the BTD 700. However, I noticed a distinct lack of background noise in both clips, which is helpful in busier environments. I’ll also note the overall voice quality isn’t pristine, but it’s clear enough to use for work calls — even if you’re the main presenter. 

Battery life

Sennheiser promises that you’ll get up to 60 hours of battery life on a charge with the HDB 630. That’s the same staggering figure the company claims on the Momentum 4. And yes, that’s with ANC enabled, but you’ll only achieve that if you’re listening to standard resolution tunes. Based on my testing with a mix of noise cancellation and transparency mode while I was listening to music and taking work calls, I have no reason to believe the company’s numbers don’t hold true. If you choose to listen entirely via the BTD 700’s higher quality output, you can expect up to 45 hours of use on a charge. That’s still quite a long time considering a lot of the competition runs out at around 30 hours — and that’s without high-res music. 

Due to all of the signal processing that helps with the acoustic performance on the HDB 630, they can only be used when they’re turned on. Unlike some wireless models, you can’t use these as wired headphones when the battery is spent. However, if you find yourself with a completely depleted battery, a 10-minute charge will give you up to seven hours of use. The company doesn’t specify streaming resolution for that number, but I assume it’s at standard definition. Still, you’ll get a few hours of higher-res music in that time, which should be enough to get you through a work session, evening commute or that new album you’re dying to play for the first time. 

The competition

Billy Steele for Engadget

In the realm of flagship headphones, any company’s top-of-the-line model will set you back $500 these days. I look back fondly on the time when $300-$350 got you the best Sony had to offer. While the HDB 630 is expensive, it’s also in the same ballpark of what you’ll pay for the Bose QuietComfort Ultra Headphones ($450), the Sony WH-1000XM6 ($458 currently) and the AirPods Max ($549). Each of those have their advantages over the rest of the competition, with the 1000XM6 offering the most complete package overall. However, when it comes to pure sound quality, neither of those three are at the top of the heap. 

Up until now, that title belonged to the Noble Audio FoKus Apollo. At $650, those headphones are even more expensive than the HDB 630, but their stock tuning will appeal to more listeners and the soundstage is wider and more immersive. There’s also Bowers & Wilkins’ Px7 S3 for a slightly cheaper $479. It delivers the company’s warm, inviting sound and attention to finer details. After spending time with the HDB 630 though, these alternatives are just that — alternatives — as the new Sennheiser headphones are now my pick for best overall sound quality. 

Wrap-up

I get it:  in the current financial climate, $500 is a lot to pay for headphones (or anything else, for that matter). You can find a number of perfectly capable sets of ANC headphones for much less given how frequently things go on sale these days. However, what you won’t find is an option that gives you anything close to the performance of audiophile-grade, open-back headphones. That’s really what Sennheiser is doing here, and the HDB 630 slots nicely into the company’s HD 600 series of high-end cans. 

As good as the HDB 630 is sound-wise, I can also appreciate that these aren’t the best headphones for everyone. The company’s Momentum 4 is still a very capable set of headphones and it’s now available for about $250. If you crave the best sound quality that still offers the convenience of wireless headphones — and you’re okay with a few extra steps — the HDB 630 is a worthy investment. Just don’t leave home without that dongle.
