The Oura Ring 5 is 40% smaller than its predecessor, measuring 6.09mm wide and 2.29mm thick compared to 7.99mm and 2.88mm on the previous model. Oura says the reduction was achieved by redesigning the mechanical, electrical, optical, battery, and sensing architectures, and the company claims the new form factor more closely resembles a traditional wedding band. Despite the smaller size, Oura says battery life remains at approximately one week per charge.

The ring's sensing system has also been overhauled. A new signal architecture uses precision-engineered sensor domes for better skin contact, more powerful LEDs, and twelve signal pathways that Oura says deliver greater accuracy across more finger types and skin tones.

Other new features include live workout tracking with real-time pace, distance, and heart rate via a connected device, a Brain Health Study through Oura Labs pairing cognitive assessments with biometric data, and a time-based Data Deletion tool allowing users to erase data from specific periods without affecting their full history.

An optional new Charging Case accessory provides one month of battery and supports wireless charging, priced at $99. Oura is also introducing a Locate feature to track misplaced rings and charging cases.

The Oura Ring 5 is priced at $399 in Silver and Black, with Gold, Stealth, Brushed Silver, and Deep Rose finishes priced at $499. The Oura Ring 4 in ceramic remains available at $349. An Oura Membership is required for full functionality at $5.99 per month or $69.99 annually. Global pre-orders open today, with shipping beginning June 4.
