How it works

It makes voices clearer, not just louder.

Cheap $99 amplifiers turn every sound up at once, so the dishwasher gets as loud as your grandson. Certus One and Certus Pro use ClearVoice™ SpeechLift, which lifts voices and leaves other sounds alone. Certus Max uses its own 32-channel chip to do the same job.

  1. It finds the voice

    Speech sits in a narrow band of sound. ClearVoice™ listens for that band and separates it from the noise around it.

  2. It lifts the words

    Voices come up. The clatter, the traffic and the dishwasher stay where they are, so you hear what people say.

  3. You set it up yourself

    Certus One is set with one button. Certus Pro is set once from the app. Certus Max is set from its touchscreen case, or the app if you like. You do it at your own kitchen table, with no appointment. Your own voice sounds normal again within a few days.

Wore them to my grandson’s wedding

My daughter ordered these about six weeks before my grandson’s wedding. She said she was tired of me missing things. I only put them in that morning to keep the peace. I heard the whole best man’s toast. Usually I laugh when everyone else laughs and hope for the best. If you are on the fence, get them before the big day, not after.

Heard the cardinal before the alarm went off

Silly thing to write a review about, but that's the one that got me. The second morning I sat up in bed and there it was, singing in the maple out back. I have lived in this house since 1988. Voices are the reason you buy them. The little sounds are what surprised me.

Marilyn K.✓ Verified buyerCertus Pro
★★★★★

The audiologist quoted $5,800. This was a fraction of that.

Two appointments and a hearing test, then he quoted me $5,800 for the pair and started talking about a payment plan. Medicare doesn’t cover hearing aids, so I would have paid all of it. I never went back. Around the house they are very good, and on the phone too. In a restaurant I can hear the person across from me. That is what I wanted.

Calls in both ears, and it works with my Android

My last pair only worked well with iPhones, and I have a Samsung. These paired in about a minute, the same way earbuds do. Now my calls come into both ears, and I don’t have to put my sister on speaker. The case shows the battery, so I never have to guess. I wish I had done this two years ago.

Very good, but here is the honest limit

At the table, on the phone, in the car, at church, all better than I expected. At the VFW on a Friday night with two hundred people and a hard floor, they help but they don't fix it. I knew that going in. I'm giving four instead of five because I think the page could say it more plainly.

I stopped staying home

Over about two years I stopped going to things. I never decided to. I just kept finding reasons. My son bought me these in May. It took about four days before they felt normal. I called my sister in Phoenix last week and we talked for over an hour. I've started going back to my Tuesday card game. That's all, really.

They help, but only halfway

Quiet room, good. Phone, good. Anything with more than two voices in it, not much change. Three stars is how I feel. I got half of what I wanted, for a fraction of what the audiologist wanted. I'm not sending them back, and I won't pretend they fixed everything.

An audiologist's view

Cheap amplifiers make everything louder. Good hearing aids make speech clearer.

I fit hearing aids every day, and the question is always the same. Does it lift speech, or does it just make the whole room louder? Certus lifts speech. And because the in-ear fit is so hard to see, people keep wearing them instead of leaving them in a drawer.

Our story

Why we started Certus

An open Certus case on a wooden side table beside reading glasses and a folded newspaper, under a warm lamp

It started with a drawer. Inside was a pair of hearing aids that cost more than a family vacation, worn twice. Next to that drawer was a father who had quietly stopped joining conversations. He laughed a half-second after everyone else, because he was copying the room.

The audiologist wanted thousands to try again. The cheap amplifiers whistled and made the dishwasher as loud as the talking. So we built something in between: real hearing aids at a fair price. Certus is Latin for “sure.”

Questions people ask before they buy

Is this a real hearing aid, or just an amplifier?

A real one. Certus One, Certus Pro and Certus Max are certified OTC hearing aids for adults with mild to moderate hearing loss. OTC means over the counter: no prescription, no hearing test and no appointment. A cheap amplifier turns every sound up at once. A hearing aid lifts speech, and you can hear the difference in the first five minutes.

Does Medicare or insurance pay for hearing aids?

Original Medicare doesn’t cover hearing aids. Some Medicare Advantage plans give an allowance, but only through their own network. You can use your HSA or FSA, because Certus is HSA/FSA eligible. Pay with your HSA or FSA card, and we email an itemized receipt.

Why not just go to Costco?

Costco is a fair choice, and for severe hearing loss it is the better one. A pair there costs about $1,400 to $1,800, plus the membership. You also go back to the hearing center for appointments. Certus costs far less and comes to your door. You set it up yourself at home, with no membership and no appointment.

I tried earbuds with a hearing feature. Why switch?

Plenty of people try earbuds first, and they are good on calls. But the battery runs out by the afternoon, they get uncomfortable over a full day, and everyone can see them. Certus One and Certus Pro last 16 hours on a charge and sit hidden in the ear. Certus Max puts calls and music in both ears for about 15 hours a day.

Will people see them?

Certus One and Certus Pro, no. They sit deep in the ear canal in a matte shell that follows the shape of your ear. Most people never notice, including the person you are talking to. Certus Max sits behind the ear with a thin clear wire. It is small and usually hidden by hair or glasses, but it is not invisible.

Which Certus is right for me?

If you want one button and no phone, choose Certus One. If you want to tune each ear from your phone, choose Certus Pro. If you want phone calls and music in both ears on iPhone or Android, choose Certus Max. Max also suits ear canals too small for in-ear hearing aids. Only Certus Max streams calls and music. Certus Pro uses Bluetooth for its app, and calls stay on your phone.

Can I set them up myself? Can my mom?

Yes. Certus One has one button and nothing to pair, so it suits a parent who doesn’t use a smartphone. Certus Pro runs a five-minute hearing check in the free app. If a son or daughter sets it up once, your parent never needs to open it again. Certus Max pairs with an iPhone or Android phone the way earbuds do.

Will they whistle?

Only if the tip does not seal. That is why every pair comes with tips or domes in several sizes: 12 tips for Certus One and five dome sizes for Certus Max. Once the tip seals, the whistling stops.

What if my hearing loss is severe?

Then this is the wrong product. Certus is made for mild to moderate loss. For severe or profound loss, see an audiologist for prescription hearing aids. Sudden hearing loss needs a doctor right away.

What if they don’t work for me? Will I really get my money back?

Yes, if you ask within 90 days of delivery. Email us your order number and a short reason. Wear them for at least 21 days, unless they are faulty or hurt, and try one fix we suggest, like a different ear tip size. We then send return instructions, and you mail them back with tracking. You pay the return shipping, and there is no restocking fee. We refund you within 14 days of receiving and checking them.

Will you still be here if I need help later?

Yes. A real person answers email 7 days a week. Every pair has a 2-year warranty, and you can add a Lifetime Warranty at checkout. Ear tips, wax guards and cleaning tools are sold here in the Care Kit. Certus One works with no app at all, so there is nothing that can be shut off.
