The Oura Ring 4 is the best smart ring money can buy, according to PCMag, and it now comes in four new colors, plus a more durable ceramic design. But the trade-off is a higher price.
The Oura Ring 4 Ceramic comes in new Cloud, Midnight, Petal, and Tide colors—an off-white, metallic black, blush pink, and pastel blue-green, respectively.
The new ceramic design, meanwhile, is made to be comfortable to wear for long periods while still being durable. Its Mohs hardness scale rating of 8.5 out of 10 means "it's harder than steel and approaching the durability of sapphire," Oura says.
The brand markets the ring's durability, but notes that the material can scuff from time to time. Those marks can sometimes absorb material from softer metals you come into contact with, such as a kitchen stovetop. It recommends following this guide for maintenance; the ring also comes with a polishing pad.
It's also thicker than the original wearable at 3.51mm versus the 2.88mm of the standard Ring 4. That extra thickness also makes it heavier, at between 5.1g and 8.1g, depending on which size you buy. The original Ring 4 weighs just 5.2g.
The Oura Ring 4 Ceramic has the same functionality as the original, with tech to track over 50 health metrics, including activity, heart health, readiness, sleep, women's health, and more.
The battery life estimate remains the same at between five to eight days. We found in our review that it lasts a little over seven days in real-life testing, and it takes 80 minutes to recharge.
Oura is also introducing a new portable charging case that stores five recharges, each of which takes 90 minutes. The case itself recharges by USB-C. It costs $99, but Oura has yet to reveal a release date, saying it'll be available in the "coming months."
The brand is also introducing a new feature to its app for those who own more than one Oura ring. You can now switch between your devices when you want to change for fashion purposes. This feature is now live on iPhone, and it will be available on Android on Oct. 20.
At $499, the Oura Ring 4 Ceramic is more expensive than the standard $349 Ring 4, but it aligns with the price difference between the premium gold and rose gold finishes of previous Oura smart rings.
Oura has also seemingly confirmed it won’t be launching a Ring 5 this year. Chief Marketing Officer Doug Sweeny has called this ceramic version its “biggest hardware launch of 2025.” If you’re awaiting the next-generation Oura, you may have to wait until 2027. The company took three years to develop the Ring 4.
In July, an Oura rep said on Reddit that the company "takes a different approach from many tech companies. We don’t follow an annual release cycle… Rather than releasing new versions frequently, we develop products with care, guided by quality and purpose.”
