The long read.
§ Hands-on instrument testing pending. Based on published specifications and third-party data.
Overview
The Ultrahuman Ring AIR was the company’s first-generation smart ring, launched globally in 2022 and aggressively marketed in the US through 2023–2024. It became the central exhibit in Oura’s smart-ring patent enforcement campaign: in 2024, the US International Trade Commission issued an exclusion order banning the Ring AIR from US import after Oura’s patent infringement complaint succeeded.
The Ring AIR is still sold globally outside the US (India, EU, parts of Asia, GCC, LATAM). For US buyers, the relevant Ultrahuman product is now the Ring Pro — the redesigned successor cleared for US legal sale. This review documents the Ring AIR for completeness, transparency about the patent-war narrative that defined the 2024–2025 smart-ring market, and as reference for non-US buyers still considering the older device.
What We Measured
Note: This review is based on Ultrahuman’s published specifications, the ITC exclusion order documentation, and aggregated user reports from non-US markets where the Ring AIR remains available. Hands-on instrument testing not planned for this device given its US import ban; the Ultrahuman Ring Pro is our priority for US-market hands-on validation.
What the Ring AIR did well
- Subscription-free model: full feature access without recurring fees, the original Ultrahuman positioning.
- CGM integration: pairing with Ultrahuman’s M1 continuous glucose monitor for users running metabolic-health protocols.
- PowerPlugs marketplace: third-party algorithm modules for caffeine tracking, sun exposure, jet lag, etc.
- Lightweight build: 2.4g titanium shell, among the lightest smart rings ever shipped.
Why it was banned
Oura filed an ITC complaint in 2023 alleging Ring AIR infringed multiple Oura patents covering ring-form-factor biometric sensing — specifically PPG sensor placement, sleep-staging algorithms, and form-factor design elements. The ITC ruled in Oura’s favor in 2024 and issued a limited exclusion order: Ring AIR units cannot be imported into the US. Existing US owners were not affected; new US sales effectively ceased.
This is the editorially significant fact: the ban is not about device quality or safety. It’s about IP enforcement. Buyers in non-US markets should understand the patent-war context exists, even if the device works fine in their jurisdiction.
What This Means For Buyers
If you’re in the US: Don’t buy a Ring AIR. Buy the Ring Pro (Ultrahuman’s redesigned successor that cleared the patent perimeter). The Ring Pro has better hardware anyway — 15-day battery vs 6, dual-core processor with on-chip ML, upgraded heart-rate sensor.
If you’re outside the US: The Ring AIR remains available and functional. It’s a solid subscription-free smart ring with strong metabolic-health integration via the M1 CGM. The cons section above applies — battery trails newer competitors, no GPS, app-clutter from PowerPlugs.
If you already own a Ring AIR purchased pre-ban in the US: It continues to work. Ultrahuman has committed to ongoing app and firmware support globally. Warranty support for US owners has been logistically degraded post-ban.
3-Year Cost of Ownership
| Component | Cost |
|---|---|
| Ultrahuman Ring AIR (non-US pricing) | $314–$349 |
| Subscription | $0 (none) |
| 3-year total — non-US | $314–$349 |
US buyers cannot purchase new units. Used / parallel-import pricing is volatile and we do not recommend the gray-market path.
Regulatory Status
General Wellness Device. No FDA clearance. Same status as all consumer smart rings.
The relevant regulatory context for this device is the ITC exclusion order, which is a trade-and-tariff regulatory action, not an FDA action. This is documented in USITC Inv. No. 337-TA-1383 and subsequent exclusion-order publications.
Verdict: Conditional
The Ring AIR is a competent subscription-free smart ring that became the central exhibit in the Oura patent-war narrative. For US buyers in 2026, the device is functionally unavailable — the Ring Pro is the appropriate Ultrahuman product. For non-US buyers, the Ring AIR remains a legitimate purchase, conditionally recommended for users prioritizing subscription-free + metabolic-health integration.
We classify this as a “for the record” review rather than a current US purchase recommendation. The Ring Pro review is the right place to evaluate Ultrahuman as a US smart-ring purchase today.
