The long read.
§ Hands-on instrument testing pending. Based on published specifications and third-party data.
Overview
The Noise Luna Ring Gen 2 is Nexxbase’s second-generation smart ring under the Noise consumer-electronics brand — India’s largest smart wearable company. The Gen 2 launched globally in 2024 with a polished Oura-alternative pitch: full-featured smart-ring experience at $299, no subscription, slim titanium build, and the credibility of a major Indian consumer-electronics brand.
In November 2025, Oura filed a patent infringement suit against Nexxbase in the US, mirroring the legal strategy that previously led to the Ring AIR import ban. As of mid-2026, the Luna Ring Gen 2 is effectively unavailable in the US market pending resolution of the litigation. The product remains widely sold in India and other non-US markets where it has strong commercial momentum.
This review documents the device for completeness and as reference for non-US buyers; US buyers should treat the Luna Ring Gen 2 as currently unavailable.
What We Measured
Note: This review is based on Nexxbase / Noise’s published specifications, the November 2025 patent suit documentation, and user-report data from the Indian and other non-US markets where the device remains commercially active. Hands-on instrument testing not planned for this device given its US-market unavailability.
Hardware and feature set
The Luna Ring Gen 2 ships with a complete consumer smart-ring metric set — sleep stages, sleep score, HRV, heart rate, SpO2, skin temperature trends, activity, steps, recovery. Build quality is competitive: aerospace-grade titanium with DLC coating, slim profile, consistent comfort feedback in user reviews.
Brand and ecosystem
Nexxbase / Noise is India’s largest smart-wearable company by unit volume. The brand has strong distribution within India and the Indian diaspora, with limited reach in Western markets pre-litigation. The app is functional but reportedly less mature than Oura, RingConn, or Samsung’s competing experiences — sync issues and feature gaps appear regularly in user feedback.
Battery and runtime
~4–5 days continuous wear — shorter than RingConn Gen 2 (~10 days), Ultrahuman Ring Pro (~15 days), and Oura Ring 4 (~6 days). The optional charging case extends practical runtime for travel.
What This Means For Buyers
If you’re in the US: The Luna Ring Gen 2 is unavailable for new purchase pending resolution of the November 2025 patent suit. RingConn Gen 2 (settled with Oura via royalty agreement) and Samsung Galaxy Ring (patent immunity) are the subscription-free alternatives that remain available.
If you’re in India: This is one of the strongest local-brand smart rings available, with full Nexxbase distribution and warranty support. The price-to-feature ratio is competitive within the Indian market.
If you’re elsewhere globally: Available through Nexxbase’s international distribution. Consider the Ring Pro (Ultrahuman) or RingConn Gen 2 as similarly-priced alternatives with broader Western support.
3-Year Cost of Ownership
| Component | Cost |
|---|---|
| Noise Luna Ring Gen 2 (non-US pricing) | $299 |
| Subscription | $0 (none) |
| Optional charging case | included or low-cost add-on |
| 3-year total — non-US | ~$299 |
US buyers cannot purchase new units pending litigation resolution.
Regulatory Status
General Wellness Device. No FDA clearance — consistent with the consumer smart-ring category. The current US-market unavailability is driven by patent litigation, not regulatory action.
The Oura Patent-War Pattern
The Luna Ring Gen 2’s US legal exposure follows the established pattern from Oura’s Ultrahuman Ring AIR litigation:
| Phase | Ultrahuman Ring AIR | Noise Luna Ring Gen 2 |
|---|---|---|
| Oura files complaint | Sep 2023 | Nov 2025 |
| Outcome | ITC exclusion order (2024) | Pending |
| Current US status | Banned; superseded by Ring Pro | Unavailable pending resolution |
Buyers comparing subscription-free smart rings should understand that Oura has demonstrated willingness and capability to enforce its patent portfolio against direct competitors. Devices that settle (like RingConn) or have defensive immunity (like Samsung) carry no comparable risk; devices that don’t (like Luna and Ring AIR) face structural availability uncertainty in the US.
Verdict: Conditional
The Noise Luna Ring Gen 2 is a competent subscription-free smart ring with strong commercial momentum in non-US markets. For Indian and other non-US buyers, it’s a legitimate Oura alternative at $299 with reasonable build quality and a complete metric set.
For US buyers, the device is currently unavailable for new purchase. RingConn Gen 2 (settled, US-available, $299) is the closest equivalent in product positioning and price; Samsung Galaxy Ring ($399) is the patent-immune subscription-free option for buyers who want zero exposure to Oura litigation risk.
We’ll re-evaluate this verdict if and when the November 2025 patent suit resolves and the Luna Ring Gen 2 returns to US availability.
