New Oura Ring 5, features, price and technical sheet
Why would you buy a smart ring? The most immediate answer is simple: because it can measure sleep, activity, heart rate and other health data without forcing us to carry another screen with us. But there is a second, equally important reason: if it is well thought out, it can be done without taking up the wrist, without replacing a traditional watch and without reminding us every moment that we carry technology on our bodies. The problem appears when that balance is broken and the product begins to look less like a conventional ring and more like a small piece of technology accepted on the finger. That’s where the Oura Ring 5 wants to make a move: not only does it promise to measure better, it also wants to be noticed less. Oura’s movement is going right in that direction. According to the companythe Oura Ring 5 has 40% less volume than the Oura Ring 4 and measures 6.09 mm wide and 2.28 mm thick. According to the information available, its weight ranges between 2 and 2.69 grams, depending on size. On paper, the difference may seem small because we are still talking about millimeters and grams, but in a product designed to be worn during the day, at night and during training, everything indicates that this cut should be noticeable. You’ll have to check it with the ring on your hand and on your finger, because that’s where you really decide if miniaturization changes the experience. A smaller ring, but not simpler This reduction does not come, at least according to the firm, from simply squeezing the same components into a thinner casing. The company assures that the Ring 5 has been redesigned from the inside, with an architecture designed to fit sensors, battery and electronics in a much more limited space. In his technical explanation, Oura talks about a domino effect: by modifying one part in such a small product, the rest of the design has to change too. The most delicate part of this redesign is in the sensors. Oura assures that the Ring 5 incorporates low-profile sensors to improve contact with the skin, more efficient LEDs and 12 signal paths designed to obtain more consistent readings on different fingers and skin tones. The company also claims that this generation can obtain a pulse signal up to 100 times stronger than that of wrist wearables, a fact that should be read as a brand argument, but that helps to understand why the finger continues to be an interesting territory to measure constants. Compared to the Oura Ring 4, Oura speaks of 12% more accuracy in nighttime HRV and 19% more accuracy in measuring heart rate during activities such as running, walking or cycling. All of this would be left half-done if the ring was not prepared to survive everyday use. The Ring 5 is made of titanium, a material Oura says it chose for its strength-to-weight ratio, and features a more scratch-resistant PVD coating than previous generations. Oura also presents it as water resistant up to 100 meters and with IP68 certification, so the brand proposes it as a device to sleep, train, swim or wear during the day without having to treat it as a fragile piece. Autonomy accompanies this approach of continuous use. Oura speaks of between 6 and 9 days of battery life on a charge, depending on size, and an optional case, sold separately, capable of providing up to five full charges. But the Ring 5 doesn’t just arrive with hardware changes: the company also announces new features such as Health Radar, GLP-1 Insights and AI-assisted personalized medical guidance in collaboration with Counsel Health.
