Oura Ring 5 Shrinks 40%, Easing Comfort Issues Seen in Ring 4

3 articles · Updated · ZDNet · Jun 4

Summary

  • After 24 hours of wear, ZDNET found Oura Ring 5 noticeably more comfortable than Ring 4, with the slimmer design largely eliminating the finger gap and bulk that stood out in daily use.
  • Oura says the fifth-generation ring is 40% smaller and thinner and adds one more day of battery life, achieved through a full hardware redesign including a new battery, refined algorithms and stronger LEDs.
  • The reviewer said the biggest practical change is how little the ring is felt during routine tasks, with Ring 5 appearing closer in thickness and width to ordinary jewelry than earlier smart rings.
  • Software changes are not yet the main differentiator because many Ring 5 features also reach Ring 4, and longer-term tests on battery life and tools such as Health Radar and blood pressure signals are still pending.
