THE END OF THE TRADE-OFF
You shouldn't
have to choose
Better hearing used to mean wearing something in your ear that looked medical.
Legato Frames are premium eyewear first, starting at just 27 grams and available in metal and acetate styles. All the hearing technology is built into the frame, so nothing goes in your ears.
Better hearing looks good on you.

Inside Legato SpeechSense™ AI
Noise down. Speech up.
Turning everything up makes a noisy room louder, not clearer. Here's what Legato Frames do instead.
- Step
01
Sense the sound
Built-in microphones pick up the sound around you, including the speech you want to hear and the noise you don't.
- Step
02
Isolate the speech
An on-device neural network, trained to tell speech from non-speech, processes the microphone signal in real time and isolates the speech.
- Step
03
Tune for hearing
Legato SpeechSense™ AI amplifies the isolated speech to improve intelligibility for your hearing loss.
- Step
04
Play back privately
The open-ear audio system delivers the amplified speech, to you and only to you.
What it doesn’t do
We designed Legato Frames around your privacy. Here's what they'll never do.
It doesn’t record.
Not you, and not the person across the table. Sound is processed on the frame as it arrives. Nothing is recorded, so there's nothing to store.
It doesn’t trade your data.
Nothing about you is collected to be packaged, brokered or sold. Your hearing profile exists to tune your frames, and that's it.
It doesn’t use cameras.
No cameras, anywhere in the frame. The people around you never have to wonder whether they're being filmed.
Better hearing with total privacy.
