Oura Ring 5 Official Launch: 40% Slimmer Than Ring 4 — Specs, Pricing, and What's Changed
Oura Ring 5 Official Launch: 40% Slimmer Than Ring 4 — Specs, Pricing, and What's Changed
Oura, the smart ring market leader, officially announced the Oura Ring 5 on May 28, 2026. Pre-orders opened the same day, with shipping beginning June 4, 2026. According to Kiolix Pulse trend data, the product is currently appearing on Google Search trending lists across multiple countries, with 🇺🇸 United States accounting for over 100,000 search interest units — by far the largest share of the total.
A Launch That Came Much Earlier Than Expected
Industry observers had widely expected the Oura Ring 5 to arrive in the second half of 2027. Several signals pointed to an earlier timeline: FCC filings for model codes OA13 (ring) and OA14 (charger) surfaced in April 2026, and Oura's own checkout page briefly displayed the "Oura Ring 5" label before reverting to "Ring 4." A leaked internal document posted to Reddit then pinned a specific launch date, which turned out to be accurate.
Key Changes: A Design-First Upgrade
The most striking aspect of Ring 5 is how much smaller it is. Oura is calling it the world's smallest smart ring.
| Spec | Oura Ring 4 | Oura Ring 5 |
|---|---|---|
| Width | 7.90mm | 6.09mm |
| Thickness | 2.88mm | 2.28mm |
| Material | Titanium | Titanium (new low-profile sensor domes + redesigned battery) |
| Water resistance | — | 100m |
| Size change vs. prior gen | Baseline | ~40% smaller than Ring 4 |
The new low-profile sensor domes and redesigned battery structure also cut weight significantly — starting at 2g for the smallest sizes and topping out at 2.69g even in the largest. A new physical vapor deposition (PVD) coating over the titanium shell enhances scratch resistance compared to its predecessor.
Health Tracking Features
Ring 5 carries forward the same health-tracking capabilities as Ring 4, with Oura's focus this generation on improving sensor accuracy and power efficiency rather than adding new sensor types. Tracked metrics include:
- Sleep stages and sleep quality analysis
- Heart rate variability (HRV)
- Blood oxygen saturation (SpO2)
- Skin temperature
- Menstrual cycle monitoring
- Stress levels and physical activity indicators
Oura states the ring tracks 50+ health metrics and insights. Blood Pressure Signals and Nighttime Blood Pressure monitoring (via the Health Radar feature) are slated to roll out starting June 2026 in the US, India, and the UAE.
Battery life is rated at six to nine days — a slight improvement over Ring 4's five to eight days — with Oura crediting the redesigned internals for maintaining (and marginally extending) runtime in a thinner form factor.
Charging Case
The new charging case bundled alongside Ring 5 can fully recharge the ring up to four times before needing to be plugged in itself. Given that Ring 4 already lasts up to eight days on a single charge, the case effectively extends off-grid use to several weeks depending on usage patterns. The case is sold separately at $99 and is not included with ring purchase.
Pricing and Color Options
The base model starts at $399 for Silver and Black — a $50 increase over Ring 4's $349 launch price. Premium finishes carry a $499 price tag.
| Price | Colors |
|---|---|
| $399 | Silver, Black |
| $499 | Gold, Stealth, Brushed Silver, Deep Rose |
Rose Gold has been retired in favor of the new Deep Rose finish. Available in sizes 6–13.
The Oura Membership subscription remains unchanged at $5.99/month (or $69.99/year), required to unlock the full suite of health tracking features.
A More Competitive Market
The smart ring landscape is significantly more crowded in 2026 than when Ring 4 launched. The Samsung Galaxy Ring ($399, no subscription), RingConn Gen 3 (adds blood pressure monitoring, no subscription), and Ultrahuman Ring Pro are all competing at similar price points. The subscription-free positioning of several rivals has put Oura's membership model under renewed scrutiny from consumers.
