About Certus
Hearing well should not cost thousands.
Certus makes certified OTC hearing aids that are invisible, simple and honestly priced. Staying part of the conversation should not cost $4,000 to $7,500 or take appointment after appointment. And your hearing aids should not end up in a drawer.
What the name means
certusLatin · adjective · ker-toos
“Sure. Settled. Proven. Something you can rely on.”
We did not pick a word that sounds like a badge. We picked one we would have to live up to. It is a promise about how we behave. It is also why we can say plainly what every Certus is: a certified OTC hearing aid for mild to moderate hearing loss. It is not a cheap amplifier sold as a hearing aid.
And then we put 90 days behind it, so the name is not just something we say.
Our story
How Certus started
It started with a drawer. Inside was a pair of hearing aids that cost more than a family vacation, worn twice.
And beside that drawer, a father who had quietly stopped joining conversations. He laughed a half-second after everyone else, because he was copying the room. He said “nothing, don’t worry” when you asked what he’d missed.
The audiologists wanted thousands to try again. The cheap $99 amplifiers online whistled, screeched, and made the dishwasher as loud as the talking. There was nothing in between that was honest, comfortable and affordable.
So we built it. Certus hearing aids are certified OTC hearing aids for mild to moderate hearing loss. They are small enough that people don’t notice them, and simple enough to set up at your own kitchen table. They are also priced so that trying them is not a big decision.
Hearing aids only help if you wear them. We would rather take a pair back than have it end up in a drawer.
That is why every pair comes with 90 days at home to prove itself in real life: dinners, phone calls, and the TV at a normal volume. If they are not right for you, send them back for a refund.
We think that is how buying hearing aids should work.

No sales calls and no appointment to sit through. Ask us anything by email before you buy, and take the time you need.
The range
Our three hearing aids
We would rather sell one thing that works than four things that nearly do. We launched Certus Pro once the app was ready. We added Certus Max for people who asked for calls and music in both ears.
