The Circular Ring 2 has a brand new design in which the sensors and battery have been seamlessly integrated into the round housing instead of having a flat edge on the inside like the previous model. This should improve wearing comfort, but the new ring does not have a vibration motor for haptic feedback, presumably due to a lack of space.
The ring is available in four colors, namely gold, rose gold, black and silver, while the titanium housing now has a slick high-gloss finish. The more robust housing and a completely redeveloped app are expected to eliminate some of the major criticisms of the previous models. At eight days, the battery life is the same as the Circular Pro and significantly longer than the Circular Slim.

While the complete technical specs are yet to be revealed, the manufacturer speaks of improved sensors and an integrated electrocardiogram, of which the latter is intended to detect atrial fibrillation. As is common with virtually all "smart" products in 2025, Circular also advertises a range of AI features, most notably the improved Kira+ AI assistant, which is designed to help users achieve their goals.
Price and availability
The Circular Ring 2 will be financed from February or March via a crowdfunding campaign, where the ring will have a price tag of $380. This makes the Circular Ring 2 slightly cheaper than the Oura Gen 3 and the Oura Gen 4.
