Tuned to each ear, by you
A five-minute in-app hearing check measures each ear on its own, and Certus Pro’s digital noise reduction shapes the sound to the result: speech forward, background hushed.

The quiet pullback
Every room sounds different. Your hearing should keep up.
It creeps in slowly. The TV gets a little louder every year. You ask people to repeat themselves, then stop asking and just nod along instead. You sit a bit quieter at the table because following the chatter is exhausting, so you stop trying.
It’s not that you don’t care. You’re missing half of what’s said, and pulling away feels easier than asking “sorry, what?” one more time. You’re not alone, and it isn’t your fault.
Certus Pro brings the voices back: your partner, your friends, the person beside you. Instantly, invisibly, and without a clinic, an appointment, or the thousands a prescription pair costs.
You’ve probably tried these already. Here’s why they failed:
Turning the TV up (again)
Everyone else in the room gets blasted out while you still miss half the dialogue.
Cheap drugstore amplifiers
Bulky, whistly, one-volume-fits-all boxes that make every sound louder, not clearer.
One fixed setting for every room
Right at home, wrong at the bar. A busy restaurant and a quiet kitchen need different sound, and a fixed device can’t do both.
What actually works: a hearing aid tuned to your ears
Certus Pro checks each ear in the app, tunes itself to the result, and matches the sound to the room you’re in, at a fraction of a prescription price.
The simple science
Meet the TrueTune™ Personal Sound System
The check-and-tune engine built into every pair of Certus Pro, designed to fit your ears, not “average” ears.
1
Check: it picks up every sound
Run the built-in hearing check from the app, one ear at a time, at your own kitchen table. Five minutes, no appointment.
2
TrueTune: it lifts words above the noise
Certus Pro shapes its sound to each ear’s result: digital noise reduction lifts speech to the front and pushes background hum down. You hear the words, not the room.
3
Adjust: it hands you the clarity
Four listening modes and per-ear volume, changed from your phone in a tap. No reaching up to fiddle at your ear.
A certified OTC hearing aid, built for mild-to-moderate everyday hearing loss. Real hearing aid technology, not a gimmick.
Life after Certus
Sound that follows you from room to room, and tells nobody. For good.
You deserve to feel like yourself in every conversation, not like you’re one step behind it.
Tuned to your ears, not “average” ears
The built-in hearing check sets each ear on its own, so the quiet ear gets more help and the good ear isn’t blasted.
Every room, one tap
Quiet kitchen, busy restaurant, the evening TV: four listening modes switch the sound to match the room.
Nobody has to know
At 2g and tucked inside your ear canal, they’re yours to mention or not. Most people never notice.
Adjust it from your lap
Nudge the volume from the phone in your pocket, mid-conversation, without anyone seeing you touch your ear.
What to expect
From the first listen to a different daily life
Sound either includes you or quietly leaves you out. Here is what changing that feels like, with 90 days to prove it risk-free.
First listen
Five minutes with the app, tuned to your ears
You run the built-in hearing check, one ear at a time, and hear the room come into focus with your own result.
Day 1
You stop asking “sorry, what?”
Conversations at normal volume start landing the first time, not the second or third.
Week 1
You find your modes
TV mode in the evening, restaurant mode on Sunday, and the volume lives quietly in your pocket.
Month 1
You forget you’re wearing them
Certus Pro becomes part of your day instead of a device you think about. You open the app only when the room changes.
Everything you want from a hearing aid, nothing you don’t
Premium home design
So small, most people won’t notice
An invisible-in-canal fit that sits hidden inside your ear, just 2g and smaller than your fingertip.
Rechargeable: zero battery fumbling
Pop them in the pocket case. A full charge lasts 16 hours, with up to 60 total hours of hearing on the go.
Four modes for real rooms
Quiet, Outdoor, Restaurant and Television. One tap in the app switches the sound to match the room, and per-ear volume lives on the same screen.
“What if I’m no good with apps? Will it beat me?”
Fair question. The app is what makes Pro worth it, so we built it for people who don’t like apps. Here is the honest answer.
Set up once, then forget it
Scan the QR code in the box, pair once, run the check. After that they work all day on their own; you open the app only when you want to change something.
Big buttons, plain English
Volume up, volume down, and four modes with names like Restaurant and Television. If you can send a text, you can run this.
7 pairs of tips, whistle-free fit
A loose fit is the number-one cause of whistling. Seven pairs of soft tips help you find a comfortable seal that keeps the sound clean.
Still unsure?
Wear Certus Pro at home for 90 days: three months of dinners, calls and TV. If it is not right for you, send it back for a full refund.
The honest math
What clear hearing actually costs in the US
Same goal: hear every word again. Three very different bills.
Option 1
Private audiologist
$2,000–$6,000+ per pairHearing tests, fittings and follow-up appointments. The right route for severe or complex loss, and a very big bill for everyday mild-to-moderate loss.
Option 2
The insurance route
Rarely coveredOriginal Medicare does not cover hearing aids, and most insurance plans pay little or nothing toward them. Either way, most of that clinic bill usually lands on you.
Option 3
Certus Pro
$399.99 todayA certified OTC hearing aid that checks and tunes itself to your ears at home. At your door in days, tuned in minutes, with 90 days to prove itself.

Still deciding if Certus fits your day?
Will people be able to see them?
Very unlikely. They sit completely inside your ear canal and are virtually invisible. At just 2g and smaller than your fingertip, most people won’t notice them at all.
Will they whistle or buzz?
A loose seal is the main cause of whistling. Seven pairs of soft ear tips are included so you can find a snug fit, built-in noise reduction keeps the sound clean, and the in-app check tunes each ear so nothing is turned up further than it needs to be.
Do I need a smartphone?
Yes, for the five-minute setup: you scan the QR code in the box, pair once, and run the hearing check from the free app (iPhone and Android). After that the aids work all day on their own; you open the app only to change volume or mode. If you’d rather skip the phone entirely, Certus One is our app-free pair.
Are they really rechargeable?
Yes. Charge them in the included case (like wireless earbuds). A full charge lasts 16 hours, and the case tops them up about 4 times when you’re out: up to 60 hours in total.
Are they suitable for severe hearing loss?
They’re designed for mild-to-moderate hearing loss and everyday situations: conversation, phone, television. For profound loss, a prescription aid is the right route, and we’d rather be honest than oversell.
Is this a real hearing aid or just an amplifier?
A real hearing aid. Certus Pro is a certified OTC (over-the-counter) hearing aid for mild-to-moderate hearing loss. That is a regulated category with real requirements behind it. Cheap ‘sound amplifiers’ blast one sound at everyone; Certus Pro’s TrueTune™ system checks each ear and tunes to the result, so you hear the words, not the room.
How can it cost so much less than the audiologist?
Because you are not paying for the building. A private prescription pair costs $2,000–$6,000 largely due to clinic overheads, appointments and fitting fees. Certus Pro ships straight to your door, tunes itself with the in-app hearing check, and you get 90 days at home to prove it does the job.
How does shipping work?
Every order is free, fully tracked and insured. Fast Tracked Shipping, free on every order. Your tracking link arrives by email the moment it leaves us.
What if they’re not right for me?
90-day no-questions returns. Send them back for a full refund, no hassle. Covered by a 2-year warranty.
