Lumia 2 Smart Earrings: Discreet Next-Gen Health Tracking

Lumia 2 moves health tracking from wrist and finger to the ear — where biometric signals are stronger and motion noise is lower, yielding sleep, cycle, readiness and blood-flow data more accurate than traditional bands. And it's shaped like an earring: under one gram, in gold/silver/titanium across hoops, studs and cuffs; SwitchBack™ technology even attaches it to earrings you already own. No piercings? The cuff still works. 'Most wearables compromise your style. Lumia is the first that adapts to it' — the product's own thesis, aimed squarely at users who refuse to trade aesthetics for data.
