Oura is clearing Ring 4 inventory across every size and colorway, and the prices reflect it. The Ring 4 in Gold Size 9 is down to $279, off its $499 list price at nearly half price and the lowest price any Oura Ring 4 configuration has reached on Amazon. This is a Prime Day deal for Prime members only, with a free 30-day trial available without a credit card. Every size is currently at this record low, not just the Gold 9.

The health tracker that disappears on your finger
The Oura Ring 4 tracks over 50 health metrics including sleep stages, heart rate variability, body temperature, blood oxygen, activity, stress, and women’s health metrics through Smart Sensing technology that adapts its algorithms to each individual wearer over time. The ring form factor is what makes continuous passive tracking genuinely practical in a way that a watch cannot replicate: no screen to check, no notification vibrations during sleep, no battery anxiety after a single day of use, and no social signal that you are wearing a health device. Up to 8 days of battery life means most wearers charge once a week and forget the ring exists the rest of the time.
