Oura Ring 4 and Ceramic Models Discounted by Over $100 During 2026 Prime Day

WIRED has reported that the Oura Ring 4 and Ring 4 Ceramic are available at significant discounts during the 2026 Prime Day sales event, with savings exceeding $100 on both devices. The publication describes the older model as "nearly half off," positioning it as a compelling purchase for consumers seeking a reliable fitness and sleep tracker without the premium price tag of the latest hardware.

The retailer recently launched the Oura Ring 5, which features a form factor approximately 40 percent smaller than the Ring 4. The manufacturer claims the newer model is more accurate due to redesigned sensors that sit closer to the skin and more powerful LEDs. However, WIRED’s testing indicates that there is no meaningful difference in data accuracy between the Ring 4 and the Ring 5, despite the hardware upgrades in the newer iteration.

While the Ring 5 offers a lighter and slimmer design, the publication notes that the Ring 4 remains one of the most reliable wearables tested, with excellent tracking capabilities for activity, sleep, and key health metrics. The article suggests that unless consumers are specifically prioritising the reduced size and weight of the new model, the discounted Ring 4 presents a strong value proposition.

The Ring 4 Ceramic variant is highlighted for offering pastel colourways that are not currently available on the Ring 5. WIRED describes these finishes as some of the most attractive designs Oura has produced, adding aesthetic appeal to the functional benefits of the device during the sales period.

This discount occurs within the broader context of Amazon Prime Day 2026, which features reduced prices on various health monitors and tech items. Other notable deals during the event include the Anker 737 power bank, which has reached its second-best tracked price, and the Fitbit Charge 6, which retains its status as a preferred wearable with ECG and skin temperature monitoring capabilities.
