On September 23, 2026, Law360 published an article titled “Oura Rings Lack Tech To Accurately Track Sleep, Suit Says.” The article discusses the class action lawsuit against Oura filed by Wolf Popper alleging that Oura marketed its smart rings as capable of accurately identifying and measuring sleep stages, despite lacking the clinical technology required to directly measure brain activity and other data used in laboratory sleep studies. The lawsuit further alleges that consumers paid a premium for the products based on representations regarding the devices’ sleep-stage tracking capabilities. The article states:
"Consumers increasingly rely on wearable devices to make decisions about their health and well-being, and they need accurate information about what those devices can and cannot do," Samuel Coffin of Wolf Popper LLP, attorney for the plaintiff, told Law360 in a written statement Wednesday. "Our complaint alleges that Oura promised consumers that its rings could accurately track sleep stages to provide clinically meaningful analysis, despite the products' inability to directly measure the neurological signals required to do so. We look forward to pursuing these claims on behalf of consumers who purchased [Oura rings]."
