Unboxing the Oura Ring 5 was a revelation; my first thought was, “Wow, that's tiny.” This smart ring from Oura has arrived to address users' long-standing requests for a smaller, more compact design. The Ring 5 is 40% smaller than its predecessor, measuring just 6.09 mm wide and 2.28 mm thick, compared to the Ring 4 Ceramic’s dimensions of 7.90 mm width and 2.88 mm thickness. Weighing between 2 grams and 2.69 grams, it's also significantly lighter than the Ring 4's range of 3.3 grams to 5.2 grams.
The reduction in size has a remarkable impact on comfort. The Ring 5 is now designed to fit more subtly into your jewelry collection, blending seamlessly with other rings and making it almost unnoticeable when worn. This change appeals to both new users and those who previously hesitated due to the bulkiness of its predecessors.
The Ring 5 starts at $399 and comes in six finishes: Gold (with a truer gold tone), Deep Rose (copper-like look), Silver, Brushed Silver, Black, and Stealth. The Gold version, priced at $499, is the most expensive option but offers a more refined appearance.
Compared to its predecessor, the Ring 5 boasts an impressive battery life of six to nine days, which is up from five to eight days on the Ring 4. My experience mirrors this: after receiving it at 50% charge and charging for about 30 minutes following setup, I wore it continuously for five days without needing a recharge. This longer-lasting power source makes nighttime wear more comfortable and convenient.
The Ring 5’s smaller size has also made tracking sleep and health metrics more comfortable during the night. As a tech journalist who often wears smart rings, this improvement is significant in making the ring less noticeable and enhancing user experience.
