ULTRAHUMAN Ring Air Smart Ring Bionic Gold taglia 9 UHRA-BG-09-EUL7

The ULTRAHUMAN Ring Air stands out by packing advanced health tracking into a slim, lightweight titanium ring that you can wear 24/7. Unlike bulky wristbands, it monitors sleep stages, heart rate variability, skin temperature, and activity without a screen or constant charging. This Bionic Gold model in US size 9 is built for those who want deep recovery insights with minimal daily friction.

Highlights

• Fighter jet grade titanium outer shell with hypoallergenic resin inner lining
• Up to 6 days of battery life, recharges wirelessly in 45–60 minutes
• Advanced PPG heart rate sensor plus skin temperature and 3D accelerometer
• Tracks sleep stages, HRV, SpO2, steps, calories, and recovery score

• No subscription required for core features; stores up to 7 days of data on device

In daily use

The Ring Air pairs with iOS 15.0+ or Android 8.0+ via Bluetooth Low Energy 5.0.
