Circular has unveiled its Ring 3 series, an update to its previous model with a focus on enhanced comfort and discreet design. The Pro version boasts a slimmer profile and use of durable titanium, offering health-tracking features such as heart rate and blood oxygen levels, while the Slim variant is even slimmer and lighter, ideal for those seeking a less obtrusive wear. Both models incorporate vibrating alerts for reminders and an NFC chip for contactless payments, reducing the need to fumble for smartphones. Battery life has been improved, with the Pro offering up to 12 days and the Slim up to 10. However, the Slim sacrifices some health-tracking features, including the ECG sensor and atrial fibrillation detection, to maintain its discreet design. Pricing and availability are yet to be confirmed, but expect the new rings to hit stores in early 2027.
