You might want to think twice before you put a lot of stock in the latest stress charts from your fitness wearable. A recent study from the Netherlands’ Leiden University, published in the Journal of Psychopathology and Clinical Science, has found that when smartwatches and similar devices record readings on stress, fatigue or sleep, they’re frequently getting it wrong.

Researchers studied 800 young adults using the same Garmin Vivosmart 4 smartwatch model. They compared the data the smartwatches produced with the reports that the users created four times per day about how sleepy or stressed they were feeling. Lead author and associate professor Eiko Fried said the correlation between the wearable data and the user-created data was, «basically zero.»

A representative for Garmin did not immediately respond to a request for comment. 

Stressed or sex? Your watch doesn’t know

So why do wearables like fitness smartwatches get it so wrong? Their sensors are fairly limited in what they can do. Watches like these need to be worn correctly at all times (a loose or tight watch may give poor readings, for example), and they typically use basic information like pulse rate and movement to make guesses about health.

Those guesses don’t always reflect real-world scenarios. A wearable may identify high stress when the real cause of the change was a workout, excitement over good news, or sex. There are so many potential alternatives to stress or fatigue that the watches in the study never really got it right — and the devices sometimes guessed the complete opposite emotional state from what users recorded.

The Dutch study did note that Garmin’s Body Battery readings, which specifically measure physical fatigue, were more reliable than stress indicators, but still inaccurate. And sleep sensing performed the best of them all, with Garmin watches showing a two-thirds chance of noting the differences between a good night’s sleep and a bad one.

It’s also worth noting that smartwatch sensors can become more accurate as technology improves. It would be interesting to run a similar study with the newer Garmin Vivosmart 5 to see if anything has improved, as well as see if other models like the latest versions of the Apple Watch have similar accuracy results.

Nintendo’s next summer title — and one of the few new games for the Switch 2 soon after its June launch — is the multiplayer wheelchair basketball game, Drag x Drive. It uses the console’s new Joy-Con mouse controls to simulate moving the wheels of your chair (or vehicle, as it’s referred to in-game) while playing short three-on-three matches. While it does take some getting used to, it shows off how well this new input mode works and harkens back to an era of motion-controlled gaming made popular on Nintendo’s Wii. 

Playing Drag x Drive is unique, reflecting the Switch 2 new tech. You detach each Joy-Con 2 controller from the system, place the sensors face down on a surface (which can range from a table to even your legs), and slide the controllers forward and backward to move the wheels respectively. I actually found it more comfortable on my wrists to use the controllers positioned a little wider on my thighs instead of straight up and down on a table. 

Learning to play has a steep curve, and I found my shoulders getting tired quickly as the game kept reminding me that longer strokes would move my character faster on the court. For anyone who experienced Tennis Elbow back when WiiSports came out, Drag x Drive’s bodily wear-and-tear will be familiar. 

The mouse’s controls are good — better than I expected, in fact. They feel snappy, and I was able to pull off some higher-level maneuvers when I got used to it. And as you move, you can feel a subtle vibration in each hand to help you dial in how much force you’re inputting. Moving the controllers at different speeds will adjust the turning radius. Braking (by pressing the R or L buttons) can be done independently of each wheel to further your control. There are even tricks you can pull off by using breaking and lifting the controllers in specific combinations, which the game points out will help you perform more advanced blocks and interceptions. 

Controls are the big novelty of Drag x Drive and take time to get used to, though the court and game modes offer their own unique challenges.

Moderately deep mechanics for a $20 game

The primary mode is a 3-minute three-on-three game that’s reminiscent of Rocket League (without the jetpacks). There’s an indicator always pointing toward the oversized ball. Rolling into it will pick it up. If you’re going fast enough (represented by a flashing light on your back) and crashing into someone head-on will knock it loose. And if you raise one of the joy-cons off the surface, you will lift the ball, flicking your wrist will make a shot. 

Since the court is kind of a skateboard-style bowl, you can even roll up into the air from the sides and shoot or dunk from above. These trick shots will award players with more granular points, for example, an aerial shot might award you 2.3 instead of the standard two you’d see in typical basketball. But you can still land a three-pointer from outside the boundary, but you’ll have to be lined up real well while the other five players aren’t slamming into you.

Defense also works just like you’d expect, with positioning playing the most important role. Pressing the R and L buttons together will pass the ball to a teammate. If an opponent is in the way, they can intercept. This is key since I witnessed many teams pass a ball way down the court to an isolated player while we tried to race after them to stop the shot. Like every sport, you’ll want to spread out and cover someone instead of clumping all together around the ball, like most new players often do.

While Drag x Drive curiously doesn’t refer to anything as a wheelchair (or even highlight the awesome and inclusive sport of wheelchair basketball), it’s really wonderful to see this representation. The characters can also be swapped out for one of three unit types: defense, forward or guard, all with different speed and power stats. From there, you can customise your character’s outfit and gear, with more to unlock as you play. 

Outside of the online play, there are also nine different bot difficulties you can take on, so the game is playable in single player. There are also several minigames stationed around the hub area. These include a timed race and a rebound mode where you need to chase after a bouncing ball in the hub before time runs out. They’re pretty short and not all that interesting, but they will reward you with medals to unlock gear. There are also some obstacles positioned around to play with. One example is a giant jump rope that you can bunny hop over. 

There isn’t a typical career or story campaign to work through — the main draw is the one core multiplayer mode. Considering the low $20 entry price, I wouldn’t expect anything super in-depth, making this more of a unique application of the Switch 2 Joy-Cons’ mouse mode than a long-lasting play experience. 

Drag x Drive is a shallow experience, but the skill ceiling has a lot of potential. Its low entry price makes it an easy recommendation, even if you’re just interested in trying out the new mouse controls that the Switch 2 offers. If Nintendo chooses to support the game with more content in the future, I would love to see limited-time events and more game modes get added, building on the bones of one of the most unique sports games to come out in years. 

Drag x Drive comes out on Switch 2 on Thursday. 

It might have taken longer than anyone expected, but Sonos’ entry into the premium ANC headphone market soon made waves. The Sonos Ace headphones come with everything that we expect in 2025, including a hefty price tag.

But, thankfully, most retailers are now offering a solid discount that slashes the price to just $399. That price means that you’re saving $100 off the usual asking price without the need to do anything special — no coupons and no codes are needed. You can also choose between the black and white models when ordering, but we don’t know how long this new price will last. Consider placing your order soon, before it’s too late.

CNET’s headphones expert David Carnoy liked the Sonos Ace a lot, remarking that «overall, they deliver a more premium listening experience, as well as better noise-canceling and voice-calling performance» than many other options at this premium price range, but did state that the price tag itself was an issue. They’re comfortable, have strong spatial audio and they look good to boot.

These headphones boast support for lossless audio via Bluetooth and their USB-C port, while plush memory foam ear pads ensure a comfortable fit all day long. You’ll also get up to 30 hours of battery life even with ANC enabled, while just three minutes on the charger gets you up to three hours of playback.

The newness of the Sonos Ace headphones and the rarity of Sonos deals make this one of the best headphone deals right now, especially if you like having the latest devices. 

Why this deal matters

The Sonos Ace headphones are currently available at a significant discount. You can save $100 on these if you’re quick. This is very nearly the lowest price we’ve seen, so we recommend ordering your new headphones sooner rather than later.
