Bringing Sound Into Everyday Life.
Freely Listen to Every Conversation and Moment.

With quiet design, Otoadd makes every sound journey effortless.

From 1990 to Today, and Now Into the AI Era —We Hear Differently. So We Never Stopped Inventing.

A Revolution Born From the Sounds We Missed. It All Began In 1990 – With Our Own Ears.

When our founder Blue was 3, he lost most of his hearing. For over 30 years, he’s worn hearing aids every single day. He knows the ache of missing friends’ laughter in a noisy café, the dread before every phone call, and how lonely a crowded room can feel. Traditional devices were costly, hard to adjust. Even when worn, users could still feel isolated and helpless in noisy environments. Blue lived through all of those frustrations… and then decided they didn’t have to be that way. So he built Otoadd – not just as a company, but as a promise: to create hearing aids that finally let people hear the world the way it’s meant to be heard – clearly, naturally, and full of the little moments that matter.

Reinventing the Journey of "Listening

In 2017, Blue quited from a famous tech company to start RelaJet. He had one hope: to build technology that truly understands what people feel and need. For him, hearing aids should never be expensive, complicated, or out of reach. They should be gentle, everyday tools that simply let you stay close to the voices you love. That belief — born from empathy, shaped by a lifetime of wearing hearing aids himself — is still the heart of everything we do at Otoadd.

We Make More Than Devices. We Bring Life’s Best Sounds Closer.

From day one, Otoadd has never been just about “hearing aids.” We’re here to weave beautiful sound back into everyday life. That’s why every product we create marries AI and acoustics — designed to look good, feel effortless, and above all, sound completely natural. We don’t make “assistive devices.” We make beautiful accessories you’ll want to wear every day. Not just tools that work, but quiet companions that truly understand how you want to hear the world. From OTC hearing aids to our newest spatial sound creations, Otoadd keeps gently pushing the edges — so one day, the line between technology and living simply disappears.

We Design the Way People Actually Live — Then Let Technology Catch Up With Love.
At Otoadd, we don’t chase flashy tech. We design from real life — the way you actually move through your day.That means sound that feels immediate, perfectly in place, and completely true to the moment. So you can listen to a friend without trying, join the conversation without thinking twice, and once again feel fully in rhythm with the life you love. We design by listening — first to you, then to the world around you.
