Lumia 2 Smart Earrings Health Tracker: Overview
Lumia 2 puts continuous health tracking inside a pair of earrings, combining fine jewelry design with biometric sensors that capture cleaner data than any wrist or finger-worn device.
- Ear-Based Sensing Advantage: The ear sits close to major blood vessels, so Lumia 2 captures a stronger, less motion-affected signal than wrist trackers. This means more accurate heart rate, body temperature, and blood flow readings throughout the day and night.
- 20+ Health Metrics: Lumia 2 tracks sleep stages, readiness, cycle patterns, HRV, activity, stress, and blood flow insights, giving you a fuller picture of your health than most standard fitness bands.
- Under 1 Gram, Jewelry-Grade Design: The sensor sits behind the ear and weighs less than a coffee bean. Choose from huggie hoops, studs, or cuffs in gold, silver, and titanium finishes, or attach to existing push-back earrings via SwitchBack technology.
- 7-Day Swappable Battery: Instead of overnight charging, Lumia 2 uses two interchangeable batteries. Swap in a fresh one weekly so tracking never pauses, especially during sleep.
- Research-Backed Platform: Developed with researchers at Johns Hopkins, Duke, and Harvard, Lumia 2 builds on six years of engineering and real-world testing by a Boston-based team with backgrounds at Bose, Peloton, and Philips.
Lumia 2 is a practical, low-profile health tracker worth considering for anyone who wants data without a wristband.
