You’ve Heard of Smart Watches and Rings; Meet Smart Earrings
Billed as the world’s smallest wearable, Lumia Health’s new smart earrings have a health tracker subtly embedded in the back.
Lumia Health’s newest innovation comes in the form of smart earrings that look like fine jewelry but have sensors in the back that track blood flow to the head. Pricing will be revealed when pre-orders open in January.
Boston—Smartwatches and smart rings are ubiquitous these days, worn by millions to track movement, sleep, and body metrics like heart rate and temperature.
Now, one company is introducing earrings into the wearables mix.
Boston-based tech company Lumia Health has created earrings that it says can track wearers’ real-time blood flow to help them identify patterns and conditions characterized by episodic symptoms, such as dizziness and brain fog, that may be missed as vitals such as heart rate and blood pressure read as normal.
Its new offering, Lumia 2, is made to look like fine jewelry from the front. It is available as huggies, studs, or an ear cuff in 18-karat gold-, platinum-, and rhodium-plated titanium, or a clear finish.
The tracking device, the Lumia Core, is located on the back of the earrings.
The device houses Lumia’s second-generation “PreciseLight” sensor along with processors, a battery, and additional sensors. While Lumia earrings are sold in pairs, the Core is worn on the left ear only.
It can also be attached to any push-back earring using the company’s patent-pending “SwitchBack” technology.
The ear is an “ideal sensing location,” Lumia said, due to its proximity to the heart and brain.
“This is what comes after smart rings,” said Daniel Lee, co-founder and CEO of Lumia, in a press release about Lumia 2.
“Just as Oura made rings smart, we’ve made earrings smart. Smart earrings are the ultimate wearable form factor with new capabilities possible only in the ear, unlocking meaningful medical use case potential in a consumer-first [product].”
Lumia Health developed Lumia with researchers at Johns Hopkins, Duke, and Harvard, with the goal of helping patients with chronic blood flow disorders such as Postural Orthostatic Tachycardia Syndrome (POTS) and long COVID.
However, blood flow affects energy, focus, and mental clarity, insights that can be beneficial for everyone, the company said.
The device also tracks data related to other things like sleep, temperature, and menstrual cycle.
“From seeing how the way you sit affects your blood flow and cognitive performance, to visualizing the consequences of your carb-heavy lunch choice in your post-lunch dip, to seeing how morning exercise can boost your circulation for the rest of the day—the transformative personal revelations have been endless,” Lee said in the release.
Live monitoring is available through the Lumia app.

Lee founded Lumia Health in early 2020 alongside Paul Jin.
Prior to starting Lumia, Lee invented Hush, the ear wearable that became Bose “sleepbuds,” while Jin led medical ultrasound systems at Philips Healthcare for 10 years before co-leading health product innovation at Bose with Lee.
Lumia 2 is the result of six dedicated years of research.
It’s the follow up to Lumia 1, the company’s in-ear wearable device for blood-flow tracking that was first tested in late 2024.
“At the time, it looked more like a hearing aid, focused more on function over form. We then discovered Lumia 1 could be worn as an ear cuff with the technology in the back of the ear, and also worked quite well as an earring back,” Lee told National Jeweler via email.
“That realization that we could take our advanced technology and package it into a [product] that more than half the population already wears daily was a key factor that drove the decision to make this tech more generally available.”
He added that at the same time, the company’s team members, who weren’t patients, were gaining “fascinating” insights from their blood-flow data.
“That was the turning point: recognizing that this wasn’t just valuable for people with chronic conditions, but for anyone interested in understanding their body,” Lee said.
“Those two insights together drove the decision to make the technology publicly available.”
In the press release introducing Lumia 2, Lumia Health announced $7 million in additional investment funding from J2 Ventures, BonAngels Venture Partners, and prominent angel investors, as well as $5.1 million in government contracts and grants.
The company’s funding to date totals $17.2 million.
In January, Lumia will reveal pricing and begin taking orders and announcing delivery dates for Lumia 2.
Delivery will be in the second half of 2026.
The base package will include titanium studs and a clear cuff.
Premium versions, such as performance-optimized earrings featuring a special earring back locking feature and swappable battery pack system, also will be available.
Lumia 1 is open to orders from the general public now, though certain features like sleep tracking will only be available in Lumia 2.
Lumia 2 will be supported on both iOS and Android and will be available in the United States and Canada to start, with more countries to follow.
