Bague connectée ULTRAHUMAN Ring Air – Aster Black, taille 9 UHRA-AA-09-EUL7

Unlike wrist-worn trackers that can feel bulky and interrupt sleep, the ULTRAHUMAN Ring Air packs advanced health monitoring into a slim titanium band that disappears on your finger. It continuously captures heart rate, HRV, SpO2, skin temperature, and sleep stages, then distills everything into daily Sleep, Activity, and Recovery scores.

Highlights

• Medical-grade epoxy resin inner with titanium PVD outer for all-day comfort
• 10 ATM water resistance—safe for swimming and showering
• Up to 6 days of battery life with a compact charging cradle
• On-device storage for up to 7 days of data
• Bluetooth 5.0 LE syncs with iOS 15+ and Android 8+

In daily use

The ring's 3-axis accelerometer and advanced PPG sensor track movement, workouts, and recovery without needing a display. Guided breathing sessions and a find-my-phone function add practical convenience, while the Aster Black finish keeps it discreet in any setting.
