Enterprise technology leaders evaluating wearable health trackers for employee wellness programs should note a compelling offer: the Oura Ring 4, which WIRED has named the best smart ring it has tested, is currently available at nearly half its usual price. According to a WIRED article by Boutayna Chokrane, both the Ring 4 and the Ring 4 Ceramic are discounted for Prime Day 2026, making this "one of the best opportunities" to purchase the device.
The Deal
Shoppers can save more than $100 on an Oura Ring, WIRED reported. The discount applies to both the standard Ring 4 and the Ring 4 Ceramic, which features pastel color finishes. The article notes that these Ceramic colorways are among the reviewer's favorite Oura finishes and are not yet available on the newer Ring 5 model.
Why It's WIRED's Top Pick
WIRED describes the Oura Ring 4 as its "favorite smart ring" and one of its favorite fitness and sleep trackers. The key attributes cited are comfort, discretion, and consistent accuracy. It tracks activity, sleep, and key health metrics without requiring constant attention from the wearer. For enterprise deployment, the ring's unobtrusive design could minimize user friction.
Ring 4 Versus Ring 5
Oura recently launched the Ring 5, which is about 40 percent smaller than the Ring 4, according to WIRED. The newer model also claims improved accuracy through more powerful LEDs and redesigned sensors that sit closer to the skin. However, in testing, WIRED found no meaningful difference in the data collected between the two models. The Ring 4's tracking remains "excellent," making the discounted older model a very compelling buy unless the sleeker design of the Ring 5 is a priority.
Specs at a Glance
The following table summarizes the specifications of the Oura Ring 4 as reported by WIRED:
| Spec | Detail |
|---|---|
| Weight | 3.3 to 5.2 grams (depending on size) |
| Materials | Titanium with PVD coating (Black, Silver, Brushed Silver, Gold, Rose Gold); DLC coating for Stealth |

The wide size range and durable materials (titanium, water resistance to 100 meters) make the ring suitable for diverse workplace environments, though the source does not explicitly address enterprise use.
A Note on the Ceramic Edition
WIRED highlights that the Ceramic model's pastel colorways are some of the reviewer's favorite finishes Oura has made. Since these colors are not available on the Ring 5, the deal on the Ring 4 Ceramic offers a unique aesthetic option. For professionals who value both form and function, this limited-time discount on the top-rated smart ring presents a rare opportunity.
