Oura Ring 4 (Open Box)

Oura Ring 4 tracks sleep, readiness, activity, heart rate and body temperature from a titanium ring you can wear all day, with up to 8 days between charges. Data lives in the Oura app on iPhone or Android.

This unit is open box: the packaging was opened, the ring is unused or lightly handled, and it has been checked by our technicians. Charger included. Sizes 8 and 9 in gold or silver. An Oura membership, sold separately by Oura, unlocks the full set of insights.
