Lumia 2 Smart Earrings Redefine Wearable Health Tracking

In partnership with

Lumia has introduced Lumia 2, the world’s first smart earring designed to continuously monitor blood flow to the head — a breakthrough signal previously impossible to measure at the wrist or finger. Developed with researchers from Johns Hopkins, Duke, and Harvard, the technology is now available in a fine‑jewelry form factor, marking what the company calls a “category‑defining moment in wearables.”

At the heart of Lumia 2 is the Lumia Core earring back, which houses the second‑generation PreciseLight™ sensor and other health sensors. Weighing less than one gram and five times smaller than AirPods, it sits close to the brain and heart, capturing deep physiological signals. Clinical studies have shown that blood flow patterns reveal how lifestyle factors — hydration, diet, posture, and sleep — directly affect energy, focus, and mental clarity.

Beyond blood flow, Lumia 2 tracks sleep, temperature, cycle, and readiness with enhanced accuracy due to its ear‑based placement. Designed for 24/7 wear, it features swappable batteries lasting up to eight days, hypoallergenic platinum/titanium materials, and a secure locking system.

The company also announced $12.1 million in new funding, bringing total investment to $17.2 million. Lumia 2 is now open for reservation in the U.S. and Canada.
