At the 2025 CES exhibition, Circular, an innovator in the field of smart rings, grandly released its latest masterpiece - Circular Ring2. This revolutionary wearable device not only continues the classic design of the previous generation of products, but also makes a qualitative leap in health monitoring functions. Through the integration of FDA-certified atrial fibrillation (AFib) detection capabilities and advanced electrocardiogram (ECG) technology, Ring2 provides users with an unprecedented heart health monitoring experience. This smart ring is expected to be officially launched between February and March 2025, with a price of $380, bringing new options for consumers who pursue health and fashion.
The technical core of Circular Ring2 lies in its innovative ECG and PPG (photocapacity graph) sensor combination. The device uses single-lead ECG technology to accurately record the user's cardiac electrical activity, while the PPG sensor measures blood flow changes on the skin surface through optical principles. The combination of this dual monitoring system allows Ring2 to provide users with comprehensive and accurate heart health data, truly realizing "health management at fingertips".
Compared with previous generations, Ring2 has achieved significant improvements in many aspects. The most eye-catching thing is the significant improvement in its battery life. Official data shows that its battery life can reach 8 days, greatly improving the user experience. In addition, the device is equipped with a newly upgraded sensor array, which not only accurately tracks sleep quality, but also monitors a number of key health indicators. The comprehensive innovation of supporting applications brings users a more intuitive and smooth operating experience, making the management of healthy data unprecedentedly simple.
The release of this smart ring marks an important breakthrough for Circular in its fierce competition with competitors such as Oura and Ultrahuman. Circular CEO Amaury Kosman said at the launch: "Circular Ring2 is more than just a smart device, it represents our vision for the future of wearable technology. We have successfully integrated cutting-edge health monitoring technology with elegant designs," said Amaury Kosman, CEO of Circular. Created a product that is both practical and fashionable. It allows users to demonstrate their personal taste while pursuing health."
Circular Ring2 offers four stylish color options: classic gold, elegant silver, mysterious black and romantic rose gold to meet the aesthetic needs of different users. To ensure that users can choose the most suitable size, Circular has also developed an innovative digital ring size measurement function, which allows users to measure accurately through their smartphones to ensure comfortable wearing. This product will be the first to be launched in major markets such as the United States, the United Kingdom and France, and will further expand the global market in the future to bring new health and technology experiences to more consumers.
