How it works

You hear the words, not the room.

Cheap gadgets turn everything up at once, which is why the kettle ends up as loud as your grandson. Certus One and Certus Pro use ClearVoice™ SpeechLift, which works the other way round. Certus Max uses its own 32-channel chip to do the same job.

  1. It finds the voice

    Speech lives in a narrow band of frequencies. ClearVoice™ listens for that band and separates it from the room around it.

  2. It lifts the words

    The speech band comes up. The clatter, the traffic and the kettle stay where they are, so you hear the sentence instead of the surroundings.

  3. It settles in

    Certus One is set with one button. Certus Pro is tuned once from the app. Certus Max is set from its touchscreen case, or the app if you like. All three work from the first conversation. Your own voice sounds normal again within a few days.

Wore them to my grandson’s wedding in Noosa

My daughter ordered these about six weeks before the wedding because she said she was sick of me missing things. I only put them in on the day to keep the peace. I heard the whole of the best man’s speech. Normally I just laugh when everyone else laughs and hope for the best. If you are on the fence, get them before the thing you are dreading, not after.

Heard the magpies before the alarm went off

Silly thing to write a review about but that's the one that got me. Second morning I sat up in bed and there they were, warbling away in the gum out the back, and I've lived in this house since 1988. Voices are the reason you buy them. The rest of it is the bit that catches you out.

A fraction of what the clinic quoted, and it does the job

Two appointments, a hearing test, then the bloke came back with a quote of $4,500 for the pair and started talking me through a payment plan. I never went back. Around the house they are very good, on the phone very good, and at a restaurant I can hear the person across from me, which is the thing I actually wanted.

Very good, and here is the honest limit

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

Stopped me hiding away

Over about two years I stopped going to things. Not a decision, I just kept finding reasons. My son bought me these in May. Took about four days before they felt normal. I rang my sister in Perth last week and we were on the phone for over an hour. I've started going back to bowls on Tuesdays. That's all really.

Halfway there and I will say so

Quiet room, good. Phone, good. Anything with more than two voices in it, no real change. Three stars is exactly how I feel, which is half of what I wanted at a fraction of what the clinic wanted. I'm not sending them back and I'm not going to pretend they sorted it either.

An audiologist's view

Most cheap hearing aids make everything louder. Good ones make speech clearer.

In clinic I fit hearing aids every day, and the question is always the same: does the processing lift speech, or does it just make the whole room louder? Certus does the former. And the invisible fit removes the biggest reason people stop wearing them, which is feeling seen wearing them.

Why we exist

Certus started with a drawer.

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

In it: a pair of hearing aids that cost more than a family holiday. Worn twice, then left there. And next to that drawer, a father who had quietly stopped joining conversations. Who laughed a half-second after everyone else, because he was copying the room.

The clinics wanted thousands to try again. The cheap gadgets whistled and made the kettle as loud as the conversation. So we built the in-between, and named it after the only thing that matters when it is your money and your ears. Certus is Latin for sure.

Straight answers

The questions people actually ask.

Will people see them?

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

Which Certus is right for me?

Set-and-forget with no phone, choose Certus One. Tuned to each ear and controlled from your pocket, choose Certus Pro. Phone calls and music in both ears, or ear canals too small for in-ear aids, choose Certus Max. Only Certus Max streams calls and music; Certus Pro uses Bluetooth for its app, and calls stay on your phone.

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

A real one. Certus One, Certus Pro and Certus Max are hearing aids for mild to moderate hearing loss. An amplifier is an unregulated gadget that turns everything up at once. That is the difference you can hear in the first five minutes.

Why is it so much cheaper than the clinic?

Because you are not paying for the building, the receptionist or the appointments. The hardware was never the expensive part of a clinic pair.

Will they whistle?

Only if the tip does not seal. That is why every pair comes with tips or domes in several sizes, not one guess: twelve tips for Certus One, five dome sizes for Certus Max. Find the seal and the whistle goes.

Do I need a smartphone?

Not for Certus One. Put them in and they work. Certus Pro uses a free app for its hearing check and modes; if a son or daughter sets it up once, you never need to open it again. Certus Max is made for phone calls and music, so it is for people who use a smartphone.

What if my hearing loss is severe?

Then this is the wrong product. Certus is designed for mild to moderate loss. For severe or profound loss, hearing aids fitted by an audiologist are the right route, and sudden hearing loss needs a doctor, not a purchase.

What if they are not right for me?

Send them back within 90 days and we refund you in full. No restocking fee, and a person answers the email.
