Hearing technology has improved dramatically over the years, yet one of its biggest challenges has never been purely technological.
People have to actually want to wear it.
That is the problem hearing technology startup Legato is trying to address with Legato Frames, a new pair of AI-powered hearing glasses designed for adults with up to moderate levels of hearing loss. Starting at $999, the glasses integrate hearing-assistance technology directly into the arms of eyewear frames.
At first glance, it sounds like another example of artificial intelligence being inserted into a familiar consumer product. But Legato's approach represents something more interesting for healthcare. Instead of asking people to adopt another visible medical device, the company is attempting to make hearing assistance disappear into something millions of people already wear.
That could matter almost as much as the AI itself.
Traditional hearing aids solve an important clinical problem, but adoption is influenced by much more than acoustic performance. Cost, comfort, accessibility and the stigma some people associate with wearing hearing devices can all affect whether someone actually uses them.
Legato was created around the idea that eyewear could provide another path.
Rather than putting a device inside or around the ear, Legato Frames integrate the hearing technology into the arms of the glasses. The frames use an open-ear design and a dual-speaker system that directs sound toward the wearer while minimizing sound escaping into the surrounding environment.
The company says escaping sound is reduced by 99% just a few inches away from the ear.
The product is also relatively lightweight at 34 grams with lenses and offers a reported 10 to 12 hours of battery life. It comes in three styles, supports prescription lenses and includes Bluetooth connectivity for music and phone calls.
Those details are important because Legato is not simply competing with hearing aids on hearing assistance. It is trying to make the product function as ordinary eyewear too.
That changes the proposition.
Instead of asking someone to wear glasses plus a hearing device, the same object potentially serves both purposes.
The more interesting technical challenge appears when the wearer enters a noisy environment.
Traditional hearing devices often use directional microphones and other processing techniques to emphasize sounds coming from particular directions. But separating a conversation from a complicated mixture of voices, music and environmental noise remains difficult.
Legato says its AI system approaches the problem by distinguishing voices from background noise. It then amplifies the voices while reducing unwanted sounds.
In practical terms, the goal is straightforward.
Imagine sitting in a crowded restaurant.
The person across from you is speaking. Plates are moving. Music is playing. Other conversations are happening around the room.
Simply making everything louder does not necessarily help. In some circumstances, it can make listening more difficult because the unwanted noise becomes louder too.
The challenge is identifying what the wearer actually wants to hear.
That is where AI becomes useful.
Rather than treating every sound equally, an AI-based system can attempt to separate speech from the surrounding acoustic environment and prioritize the information that matters.
Importantly, Legato says the processing happens directly on the glasses. The frames do not contain cameras, and the company says conversations are not recorded.
That is a significant product decision at a time when AI glasses are generating growing privacy concerns. A wearable designed to understand someone's acoustic environment inevitably raises questions about what happens to the sounds it detects. Local processing and the absence of cameras may help Legato position the device very differently from smart glasses designed to continuously understand the world around the wearer.
Legato's founders have unusually relevant experience for this particular intersection of products.
Mehul Trivedi previously worked at Bose, where he led the creation of Bose Frames, and later worked at EssilorLuxottica on smart eyewear, including the Meta Ray-Ban glasses. Co-founder Steve Romine previously ran Bose's hearing aids division and later served as COO of hearing care company Audicus.
The two founded Legato in 2024 around the intersection of smart eyewear and hearing technology. The company emerged from stealth with $12 million in funding before launching its frames.
That background helps explain why Legato Frames look less like a traditional medical device and more like a consumer wearable.
And that distinction matters.
Healthcare often assumes that if a technology works clinically, people will naturally use it. Human behavior is rarely that simple.
People care about appearance.
They care about comfort.
They care about whether something makes them feel older, sicker or visibly different.
They care about whether using a healthcare product changes how other people perceive them.
Those concerns can easily be dismissed as cosmetic, but from a product adoption perspective they are anything but superficial.
A clinically useful device sitting unused in a drawer delivers very little value.
If embedding hearing assistance into ordinary eyewear makes someone more willing to use it consistently, the form factor itself becomes part of the healthcare intervention.
Legato also reflects a larger transformation happening across consumer health technology.
For decades, medical devices tended to look unmistakably medical.
Increasingly, the boundary between consumer electronics and healthcare technology is becoming harder to see.
Watches can monitor heart rhythms and physiological signals. Rings can track sleep and recovery metrics. Smartphones can perform increasingly sophisticated health assessments. Earbuds are beginning to incorporate hearing-related capabilities.
Now eyewear is becoming another health interface.
That transition creates enormous opportunities, but it also requires some restraint. Legato Frames are designed for adults with up to moderate hearing loss. They should not automatically be interpreted as replacements for professional hearing evaluation or as appropriate for every form of hearing impairment.
That distinction is particularly important in healthcare technology.
A product can make access easier without making clinical expertise unnecessary.
The best consumer health technologies often work because they lower the friction between people and care, not because they eliminate clinicians from the equation.
There is a tendency to imagine the future of healthcare as increasingly futuristic.
More screens.
More sensors.
More visible technology.
More complicated devices.
Legato suggests another possibility.
Perhaps some of the most successful healthcare technology will become less visible.
A person may wear glasses because they need prescription lenses while simultaneously receiving hearing assistance. A watch may quietly detect physiological changes while still functioning primarily as a watch. A ring may monitor sleep while looking like jewelry.
The healthcare functionality moves into the background.
That may be especially important for conditions where stigma or inconvenience prevents people from using technologies that could help them.
Legato Frames still have plenty to prove in real-world use. Consumers will ultimately determine whether the hearing performance, comfort, battery life and $999 starting price make the product compelling enough to compete with established hearing solutions.
But the underlying product idea is worth watching.
Artificial intelligence may eventually transform healthcare through extraordinary new diagnostic systems and autonomous technologies.
It may also create meaningful change in a much quieter way.
By taking a medical device people hesitate to wear and turning it into something they already do.
Sometimes the future of healthcare technology does not need to look futuristic at all.
Sometimes it just needs to look like a pair of glasses.
For years, some of the biggest names in artificial intelligence have made extraordinary predictions about what AI could do for medicine. Faster drug discovery. Personalized trea...
