Smart rings have progressed rapidly within the past couple of years — in the mass market space as well as research labs. At CES 2025, we saw Circular reveal a smart ring with atrial fibrillation (AFib) detection, while Ultrahuman put smart ring tech inside gold and platinum shells.

Enter Viv Health, a South Korea-based digital health startup, with its Viv Ring. This one does things differently, in quite a literal fashion. Its claim to fame, apart from a polished design? Personalized AI-generated sleep sound.

The Viv Ring pulls all the tricks you would expect from an average smart ring, which includes heart rate tracking, heart rate variability, stress levels, blood oxygen saturation, activity, and sleep.

The device doesn’t stop there, however. It combines all the biomarker readings and employs AI algorithms to create personalized sleep sounds — or, as Viv Health likes to call it, “generative sleep aid sound technology.”

The smart ring will synthesize sounds inspired by ocean forests, birds chirping, ocean waves, deep sea, and rainfall. But instead of serving stock audio, Viv mixes them with monaural and binaural tunes to supposedly enhance sleep quality.

Would you like some AI sound for your sleep, sir?

Viv claims that its tech stack carefully assesses the whole set of biosensing data, “constructing AI algorithm-driven personalized sleep audio that significantly improves sleep quality.”

Now, those are rather novel claims, as scientific research has mostly focused on white/pink noise and multi-audio stimulation. The consensus, however, varies. Research and meta-analyses lean more toward the inconclusive end, while others claim that white noise and sound are good for sleep quality.

Since Viv is creating custom sounds using generative AI algorithms, we are in an entirely new territory here. The company, however, harbors grander plans before 2025 comes to an end.

A Pro version of the Viv ring is already slated for launch later this year, and this one will allow continuous blood pressure sensing and AFib detection. The former is no longer an alien concept.

At CES, Novosound showcased an ultrasound blood pressure measurement sensor that is destined for smartwatches and smart rings. Samsung has already implemented it on its smartwatch, even though it uses a PPG sensor to estimate blood pressure levels.

Viv Health is currently in the process of getting the regulatory certifications and aims to put the Viv Ring on sale next month.

Halliday’s fact-checking smart glasses have a screen and a crazy control system

Smart glasses and smart rings are two of the biggest current wearable tech trends, so it makes sense for there to be various new examples of both at CES 2025. What new product would be complete without a big dollop of AI inside?

Newcomer Halliday has unexpectedly brought all three of these trends together into one fascinating product for the technology trade show, and Digital Trends had a conversation with the company’s co-founder, Carter Hou, to find out more.

One of the worst smart rings we reviewed in 2024 is getting a successor
Circular Ring 2 in Gold.

In the world of wearables, it seems that smart rings have reached peak popularity in the last couple of years. Though the Oura Ring is still the gold standard, that’s not stopping competitors like Circular, which just announced its next-generation Circular Ring 2 at CES 2025.

In 2024, our own Andy Boxall reviewed the original Circular Ring Slim, as well as a revised version that came out several months later. However, he wasn’t very impressed with the Circular Ring Slim, as it had several flaws and only got a 1.5/5 rating. Circular clearly had its work cut out for it, and thankfully, the Circular Ring 2 sounds like an improvement.

This new Belkin accessory transforms your iPhone into a digital camera
The Belkin Stage PowerGrip attached to an iPhone.

The iPhone has a powerful camera built-in, but what if you could turn it into a proper digital camera that can keep you snapping Ansel Adams-worthy pictures all day long? Belkin's newest accessory promises to do just that, and we really hope it works. The Stage Power Grip is a more ergonomically designed accessory that helps you take great shots while reducing shake, and it's just been announced at CES 2025.

Belkin hopes to release the Stage Power Grip sometime in May, but that date isn't set in stone (nor is the price). It functions as both a button to take pictures and a grip to help you keep a steady hand. It attaches to your iPhone via MagSafe and includes a 10,000mAh power bank, too. There's also a built-in USB-C cable for charging other devices (as well as your iPhone, if needed).
