Legato emerged from stealth on Wednesday with $12 million in funding and a first look at Legato Frames, AI-powered hearing glasses that embed voice-separation technology into standard eyewear arms. The round came from Neotribe Ventures, Listen, and Village Global, and the product is scheduled to ship later this fall through select eye-care providers. The pitch is to convert hearing care from a stigmatized medical purchase into a routine eyewear one.
The market gap is the entire thesis. An estimated 50 million adults in the United States have hearing loss, but only around 20% of those with a diagnosis seek treatment — a roughly 40-million-person underserved population that traditional hearing aids have failed to convert. Legato is targeting the mild-to-moderate segment, which the company says is the largest slice of that group, and positioning price, comfort, and appearance as the three barriers it wants to remove at once.
Legato was founded in late 2024 by Mehul Trivedi and Steve Romine, both of whom come out of Bose. Trivedi led the creation of Bose Frames before moving to EssilorLuxottica, where he ran smart eyewear efforts and worked on the Meta Ray-Bans. Romine ran the hearing aids division at Bose and later served as COO of Audicus. The founding team is a rare combination of eyewear-industrial-design experience and clinical-hearing distribution experience, which is exactly what a category-crossing product needs.

Key facts
- 01Legato raised $12M from Neotribe Ventures, Listen, and Village Global to launch AI hearing glasses called Legato Frames later this fall.
- 02The company targets the 50 million US adults with hearing loss, only 20% of whom seek treatment.
- 03Legato Frames use a dual-speaker system that cuts sound leakage by 99% a few inches from the ear.
- 04Co-founders Mehul Trivedi and Steve Romine previously built Bose Frames and ran Bose's hearing aids division.
- 05Trivedi says the product is designed to stay on users for 16 hours a day.
The technical differentiator is on the signal-processing side. Traditional hearing aids rely on directional microphones that focus on a chosen direction — effective in a quiet room, less so in a restaurant. Legato uses an AI system to separate voices from background noise and amplify only the voices, aiming to reduce the cognitive load that pushes many hearing-aid owners to stop wearing them. That listening fatigue is one of the most-cited reasons the 80% of untreated adults never adopt or abandon devices.
The hardware is built around discretion. Legato developed a proprietary acoustic system, signal-processing stack, and mechanical architecture to fit the components into a normal-looking eyewear frame. The Frames use an open-ear, dual-speaker design that beams sound toward the wearer while canceling leakage, cutting audible sound by 99% just a few inches away from the ear. That matters for a product meant to be worn all day in public without broadcasting a private conversation.
Trivedi frames the goal as making hearing correction feel like vision correction — a purchase you make, forget about, and repeat every few years. He argues the analogy has always been the point of failure for the hearing aid industry: eyeglasses became universal because they are cheap enough, comfortable enough, and socially neutral enough that nobody thinks twice.
Legato says Frames will cost a fraction of traditional hearing aids, which typically run several thousand dollars a pair, and may be eligible for vision insurance when purchased through an eye-care clinic. Routing through optometrists rather than audiologists is a distribution bet — it puts the product in front of the tens of millions of adults who already show up for annual eye exams but have never scheduled a hearing test. Trivedi cites a target of 16 hours of daily use, positioning Frames as an all-day wearable rather than a situational medical device.
The competitive picture is crowded but unformed. Meta Ray-Bans have shown the market will accept camera-and-audio-equipped eyewear from a mainstream brand. Bose exited the consumer hearing aid business. EssilorLuxottica dominates prescription frame distribution. Legato is trying to slot between all three: a hearing-first product with the industrial design of consumer eyewear and the clinical distribution of a medical device. Execution risk sits mostly in retail rollout — convincing eye-care clinics to stock, fit, and support a device outside their traditional catalog is a slower process than DTC.
Legato's launch is a useful data point on where AI-in-hardware is actually landing. The most defensible consumer AI hardware plays right now are the ones that solve a specific perceptual problem — voice separation, translation, transcription — inside a device people already wear. That is a narrower and more durable wedge than a general-purpose AI pin, and it comes with existing insurance rails and retail channels. If Legato can convert even a single-digit percentage of the 40 million untreated adults, it becomes one of the largest consumer AI hardware categories by unit volume without ever competing for the smartphone-replacement narrative.
