Oura Ring 4 Ceramic Midnight

Expertly crafted for quality and precision, Oura Ring 4 provides valuable insights into your holistic health – sleep, activity, stress, heart health, cycle and more.

Key Features:

SIZE BEFORE YOU BUY - Oura Ring 4 sizes are different from standard ring sizes. Size yourself with the Oura Ring 4 Sizing Kit.

QUALITY MATERIALS – Crafted with a high-performance zirconia ceramic exterior and a seamless titanium interior, this ring delivers exceptional durability, lightweight comfort, and a premium feel. Water resistant up to 100m (328 ft), it's designed for everyday wear. Minor scratches from regular use are natural, while surface scuffs from contact with metal objects can typically be erased to help maintain its polished finish.

OURA MEMBERSHIP - First month of membership is free with your purchase, $6.99/mo afterwards. Offer available to new members only. Or opt for the annual prepaid option for $79.99. Membership is tied to your account via the Oura App, not your physical ring.

ACCURACY - SMART SENSING - Oura tracks over 30 biometrics, including sleep, activity, stress, heart health, and women’s health metrics. Oura Ring 4 is powered by Smart Sensing, which adapts to you — delivering accurate, continuous data, day and night.

LONG LASTING BATTERY - With up to 8 days of battery life, no screens and no vibrations, Oura Ring 4 allows you to focus on the present. From a workout to a night out — you’re free to forget it’s on. Until you start getting compliments.
