Oura Ring 4 - Silver - Size 9 - Size Before You Buy Silver 9

TLDR Review: Oura Ring 4 Silver Size 9

Published: December 11th, 2025

Verdict

The Oura Ring 4 in Silver offers a sleek, comfortable, and powerful way to track a wide range of health metrics discreetly without wearing a watch. Its strong points lie in sleep and recovery insights, long battery life, and style. However, if you’re looking for real-time heart rate tracking during exercise or want full access to all data without a subscription, this ring might frustrate you. Be sure to order the sizing kit first to avoid fit issues and keep in mind that ongoing subscription fees are needed for most useful features. If workout heart rate monitoring is a priority, consider combining it with a dedicated fitness tracker or smartwatch.

Top pro:
Extremely comfortable and lightweight for 24/7 wear, including during sleep
Top con:
Heart rate tracking is infrequent and poorly suited for exercise; no continuous monitoring during workouts and manual checks require being still
