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.
Sizing matters, get the kit first
Oura Ring 4 uses sizing that differs from standard jewelry rings, and the company strongly recommends ordering the free Sizing Kit before purchasing. The kit ships separately and lets you test the fit across different finger sizes before committing to a configuration. At this clearance price the temptation to skip that step is real, but an ill-fitting ring defeats the purpose of continuous health tracking since sensors need consistent contact with the skin to produce accurate readings. The sizing kit is available through Oura’s website at no cost.
The Oura membership that powers the AI Advisor, trend analysis, and personalized health insights costs $5.99 per month after the first included month. That subscription unlocks the full value of the 50-plus tracked metrics through contextualized insights rather than raw data, and the AI Advisor surfaces recommendations based on individual patterns rather than generic wellness advice. The ring itself is also HSA and FSA eligible, which reduces the effective purchase price for anyone with a health savings account.
At $279 at nearly half its $499 list price, the Oura Ring 4 is at the lowest it has ever sold for on Amazon across all sizes. The 4.0-star average across over 8,000 reviews reflects honest feedback on a product that requires patience during the initial calibration period before its insights become personalized and reliable. For Prime members who have been tracking Oura pricing and waiting for a meaningful discount, this clearance event is the window that has not existed before.
