1,287 customers rate it 4.8 out of 5, and 96% give it 4 or 5 stars.
The pattern across the reviews is consistent: it works well in quiet rooms and one-to-one conversation, it works less well in restaurants and crowds, and people who expected clinic-grade performance in noise are the ones who left the low scores. Read the critical reviews before you decide.
Is Certus Hearing a real company?
Yes. Certus Hearing sells the Certus One direct to consumers through its online store.
An estimated 28.8 million U.S. adults could benefit from hearing aids. Among adults age 20 to 69 who could benefit, only about 16% have ever used them.
Original Medicare does not cover hearing aids or exams for fitting them. Some Medicare Advantage plans offer hearing benefits, but coverage depends on the plan.
A 2026 survey of more than 1,100 hearing-aid purchasers found an average of $2,694 a pair across channels: $502 for OTC, $1,674 at Costco and $4,727 at traditional clinics without insurance.
Ranked by how many readers marked them useful, positive and critical alike.
Found out at 65 that Medicare covers nothing
Julie · Verified purchase, 🇺🇸 United States ·
That was the part that got me. I turned 65, went in for the free test, and the audiologist quoted me $4,400 for the pair. I said I'd put it through Medicare and she told me Original Medicare doesn't cover hearing aids. Not a copay, not partial, nothing. My supplement doesn't either. I priced Costco after that, which was a lot more reasonable, and then I found these and tried them first because I could return them. At home very good, on the phone very good, in a restaurant I can hear the person across from me, which is what I actually wanted. I never went back for the $4,400.

I'd stopped going to things
Richard J. · Verified purchase, 🇺🇸 United States ·
This is a little personal but I'll put it in case it helps somebody. Over about two years I stopped going out. Not a decision, I just kept finding reasons. The big family things first, then coffee with the girls, and then I realized I hadn't had a real conversation with anybody in two weeks. It's easier to stay home than keep asking people to repeat themselves. My son got me these in May. Took about four days before it felt normal, your own voice sounds strange at first, apparently everybody gets that. Called my sister last week and we were on for over an hour.

Wore them to my grandson's wedding
Denis White · Verified purchase, 🇺🇸 United States ·
My daughter ordered these about six weeks before my grandson's wedding because she was tired of me missing half of everything. I wasn't convinced and honestly I only put them in that morning to keep the peace. I heard the whole best man's speech. I haven't managed that in years, normally you laugh when everybody else laughs and hope for the best. The volume was fine right out of the box, we didn't change a thing. Middle tips, which is what's already on there. Comfortable from nine in the morning until midnight and my ears weren't sore. If you're putting it off, get them before the thing you're dreading, not after.

Four months and nobody at the club has noticed
Fred F. · Verified purchase, 🇺🇸 United States ·
The whole thing for me was not wanting the big beige one behind the ear. My brother has those and you can spot them across the room. These sit down in the ear and my hair is short, so I figured somebody would say something. Four months and not a word. Sound is good, better in a quiet room than a noisy one obviously, but I can hear the caller now which I couldn't before. Charging is easy, they go in the case on the kitchen counter.

Try the other tips before you give up
Maureen R. · Verified purchase, 🇺🇸 United States ·
The size they come with was too small for me and I got some whistle when I put my glasses on. There are spare tips in the packet, three sizes, and swapping takes about ten seconds. Went up a size and it's been silent since. Worth saying because I would have sent them back thinking they were defective.

No batteries, that was the reason
Len H. · Verified purchase, 🇺🇸 United States ·
I have arthritis in both hands and the reason I never got hearing aids is those tiny batteries. My mother had them and I remember her on the floor looking for one that rolled off. These have none, they sit in a little case and the case plugs in like a phone. In at night, ready in the morning. Haven't touched a battery since March. Took me about a week to get them in right, I won't pretend day one was easy. I can do it without the mirror now.

Waste of time for me
Ted W. · Verified purchase, 🇺🇸 United States ·
Im deaf in one ear, properly deaf, and these did NOTHING for it. Doctor told me afterwards nothing at this price would have. Should have asked first instead of ordering off an advert. Got a refund.

Reply from Certus Hearing
Sorry this wasn't right for you. Certus One is designed for mild to moderate loss. For profound loss on one side you'd be looking at a CROS or bone-conduction device, which has to be fitted by an audiologist or your ENT — no over-the-counter aid at any price would have helped. Your refund shows as completed.
They are reviews left by customers who bought Certus One and collected after delivery. They appear in full, including negative reviews. Reviews are never paid for, incentivised with a discount, or removed for being critical. The collection and verification process is set out on the how-we-verify page.
What is the average Certus One rating?
4.8 out of 5 across 1287 reviews.
Does Certus One work for severe hearing loss?
No. Certus One is for perceived mild to moderate hearing loss in adults 18 and over. It is not suitable for severe or profound loss, single-sided deafness, and anyone under 18. The low-star reviews on this site are mostly from people whose loss was outside that range, and anyone with sudden or one-sided hearing loss should see a doctor rather than buy any over-the-counter device.
How much does Certus One cost in United States?
$179.99 for a pair, against a compare-at price of $309.99. It comes with a 90-day home trial and a 2-year warranty.
Is Certus One a hearing aid or an amplifier?
It is a rechargeable in-canal device intended for perceived mild to moderate hearing loss, the same use case the FDA's over-the-counter hearing aid category covers. It is not a prescription device and it is not fitted by an audiologist.
Can I return it if it does not work for me?
Yes, within the 90-day home trial. Several reviewers on this site describe returning theirs, and those reviews are still published.
