"To make something 40% smaller without sacrificing an ounce of accuracy, we had to rethink every assumption—the sensors, the battery, the architecture, the geometry of the ring itself." In addition to boasting low-profile sensor domes for better skin contact, more powerful LEDs, stronger signal pathways, and enhanced durability, the Oura Ring 5 can be found in two new finishes: a redesigned Gold in a lighter, modern shade that more closely resembles true gold and rich Deep [Rose](https://www.trendhunter.com/trends/essentials-by-casetify).
