“My wife has made my phone calls for about ten years. She’d take the phone, have the conversation, then tell me what was said. Since January she hasn’t had to do it once.”

Calls in both ears, the touchscreen case, and how it really sits behind the ear.
donna.k.1957“My daughter called from Denver and her voice was right there in both ears. No speakerphone, no phone mashed against my head.”
gary.whitfield.oh“I figured I’d have a big plastic thing behind my ear. It’s a little silver piece and a clear wire. Nobody at church has said a word.”
linda.m.tucson“Both volumes are right on the lid of the case. I change them there with my coffee instead of hunting for my phone.”
sanjay.p.1961“I have an Android, and calls come into both ears just the same. Now I answer with my hands full and keep cooking.”Rated 4.9/5 by 1,489 verified reviews · read their reviews below
All three are certified OTC hearing aids for mild to moderate hearing loss. Each has the same 90-day home trial, 2-year warranty and free shipping. Only the Max streams calls and music into your ears.
Set it once and forget itSits deep in the ear canal, out of sight. One button, no app. Calls stay on your phone.
See Certus OneTune each ear from your phoneSits in the ear canal, nearly out of sight, with a hearing check and four modes in the free app. Calls stay on your phone.
See Certus ProCalls and music in both earsSits behind the ear with a soft dome, so it fits small ear canals. Touchscreen case. iPhone and Android.
You press the phone hard against your good ear, then switch to speaker and turn it all the way up. You still miss the name, the time, the callback number. Then you hang up and guess at what was said.
Face to face you can read lips and fill in the gaps. On the phone there is nothing to read. So calls go to voicemail, and your wife or daughter calls the doctor’s office for you. FaceTime with the grandkids turns into smiling and nodding.
Certus Max puts the call in both ears. Your phone sends the voice straight to both hearing aids over Bluetooth. It works on iPhone or Android. No speakerphone, and no phone pressed to your head.

The whole house hears your call, and the words still run together.
Most are amplifiers that turn every sound up at once. “Bluetooth” on the box often means an app, not your calls. And getting your money back can be a fight.
If your ear canals are small, in-ear aids pinch, work loose and fall out. Most end up in a kitchen drawer.
Certus Max pairs with your phone like earbuds. Calls, music and videos go straight into both hearing aids. And it sits behind the ear, so it fits ears that in-ear aids don’t.
A real digital hearing aid with Bluetooth built in, not an amplifier. Its chip splits sound into 32 bands, so it can lift voices and keep the background noise down. One pair does two jobs: clearer conversation in the room, and calls and music from your phone.

Microphones behind each ear pick up the voices around you. The 32-channel chip lifts speech and turns background noise down.
Pair Certus Max with your iPhone or Android phone over Bluetooth once. After that it connects by itself when you take the aids out of the case.
Phone calls, FaceTime, music, podcasts and audiobooks play straight into both hearing aids, through the soft dome in each ear.
A certified OTC (over-the-counter) hearing aid for adults with mild to moderate hearing loss. Bluetooth calls and music are built in. No prescription and no appointment. A real hearing aid, not an amplifier.
The calls you used to dread become easy again.
The voice plays in both ears at once. It is night and day next to holding a phone to one ear. No speakerphone, no phone pressed to your head.
Video calls with the kids and grandkids come through clearly, so you join in instead of nodding along.
Your playlist, the ballgame or an audiobook, on a walk, in the car or while you cook. About 6 hours of music per charge.
Off the phone, Certus Max works as a hearing aid all day. That is up to 15 hours of clearer conversation.

Here is what it feels like, with 90 days at home to be sure.
Pick a dome size, pair with your phone, run the five-minute hearing check, and call someone. Their voice is in both ears.
Your daughter calls, the doctor’s office calls back, the grandkids FaceTime, and you hear all of it. You stop asking someone else to make the call.
The thin wire and the small body behind the ear stop feeling new.
You listen to audiobooks on walks and music while you cook. And talk with the people around you is clearer.

Pairs with iPhone or Android like earbuds. Phone calls, FaceTime, music, podcasts and audiobooks play straight into both hearing aids.
See the left and right volume, the mode and the battery on the case. Change the volume and mode right there, no phone needed.
The body sits behind the ear and only a soft dome (the small tip) goes in the ear. Five dome sizes in the box, so it fits ears that in-ear aids don’t.
Up to 15 hours of hearing, or about 5 hours of calls or 6 hours of music. The case recharges the aids 4 to 5 times.
An audiologist who fits hearing aids at her clinic looked at Certus Max for people who struggle on the phone.
“Most people manage face to face long after the phone has become hard work. There is no face to read on a call, so the phone is where it shows first. I see it in people whose kids live across the country. I also see it in Android users whose last hearing aids would not stream a call. Hearing the caller in both ears, instead of one phone pressed to one ear, is the change people notice fastest. And a behind-the-ear fit with a soft dome suits plenty of ears that in-ear aids never sat in comfortably.”

Fair question. It does show a little. Here is what it really looks like.
The part behind the ear is about an inch long and weighs 4 grams, less than a nickel. A thin clear wire runs to a soft dome in the ear.
It tucks behind the ear, under your hair or beside the arm of your glasses. Most people only notice if you tell them.
Not the beige kind your dad wore. No thick tube and no molded earpiece. Just a small silver-white body and a thin clear wire.
Wear Certus Max at home for 90 days: three months of calls, dinners out and music. If it is not right for you, send it back for a full refund.
Three ways to get hearing aids that stream calls. Here is what each one costs for a pair.
What clinics quote for a pair that streams calls, with the hearing test, fittings and follow-up visits. Medicare doesn’t cover hearing aids, so the bill is yours. The right choice for severe or complex hearing loss.
Good hearing aids at a fair price. You still book a hearing test and fitting visits. You drive to the warehouse for each one. A Medicare Advantage plan helps only through its own network.

Certus Max in real life
My routine since I got these: podcast on the morning walk, about an hour and a half. Golf with a couple of calls in the middle. Ballgame on the radio app in the evening. On those days the case screen shows them in the low twenties by nine at night, so I drop them in during dinner for twenty minutes. On quiet days I don't think about it at all.
Four months with these and here is my honest take. Calls are the best part. My daughter in Huntsville sounds like she's in the room, both ears, and my Android connected on the first try, which no aid I tried before managed. Music and sermons are good, not earbud good on the low end. The case is bigger than the pictures, it lives on my nightstand, not my pocket. Long call days I need a top up by supper. Four stars, keeping them.
My daughters rented the hall for our fiftieth and invited about ninety people, plus a polka band that does not believe in playing quietly. Two years ago I'd have smiled at everyone and understood nothing. This time I stood by the door and talked with every person who came in, my old foreman, the neighbors from Cheektowaga, my wife's cousins from Lackawanna. I caught the toast my oldest gave. I turned them down a little when the band started and it was fine.
Things I'd tell anyone getting these. Try the domes before you decide on fit, I went down a size. Pair them to your phone before you do anything else, then run the hearing check in a quiet room with the TV off. If you stream calls all day, plan on topping up at lunch, a long call day will run them down by supper. Outdoor mode helps with wind but does not fix it, a ball cap brim helps more than you'd think. The case is too big for a shirt pocket, it lives on my kitchen counter. And they're for mild to moderate loss, so be honest with yourself about that.
My wife and I have been married thirty one years and she runs our business phone line from the kitchen. I take the calls she can't. For years I asked customers to spell everything twice. Now the calls come through my Android into both ears and I write the order down once. She says I sound less grumpy on the phone. I didn't know I sounded grumpy.
I sell seed for a living and I'm on the phone in the pickup six hours a day. For two years I was getting numbers wrong, a 40 that was a 14, and I lost an order over it. These take my calls in both ears off my Android and I quit pressing the phone into my head. Battery is the catch on heavy days, so I charge the case off the truck at lunch. ❤️
No appointment, no clinic hearing test and no computer. A plain-language guide is in the box.
Charge the aids in the case with the USB-C cable. The screen on the case shows the battery.
Pick the dome size that feels snug and comfortable. Then pair Certus Max in your phone’s Bluetooth settings, iPhone or Android, like earbuds.
Run the five-minute hearing check in the free app, one ear at a time. Then take your first call.

No subscription and no clinic visits. Charge them, pair once, and take your first call the same day.
For people who want calls and music in their ears, or who can’t get in-ear aids to fit.
Wear them at home for three full months. Use them on the phone, on FaceTime, at the dinner table and on walks. If they’re not right for you, start a return by email within 90 days for a full refund. No restocking fee, no phone interview, no video call.
Yes. It pairs with your phone over Bluetooth, like earbuds. When a call comes in, you hear the caller in both ears. No speakerphone, and no phone pressed to your ear.
Yes. It pairs with iPhone and Android phones over Bluetooth, the same way earbuds do. Calls and music come into both ears on either one. Older phones work too, as long as they have Bluetooth. If you get a new phone, just pair it again. If it will not pair, email us and a real person will walk you through it. If it still won’t, send it back for a full refund.
You have 90 days from delivery. Wear them for at least 21 days first, unless they are faulty or hurt. Then email us. We will ask you to try one fix, like a different dome size. There is no phone interview, no video call and no restocking fee. You mail the pair back with tracking and pay the return shipping. We refund you within 14 days of getting it back, the same way you paid.
Only if the dome does not sit snugly. That is why five dome sizes come in the box. If you hear a whistle, try one size up. On a call the voice goes from the phone straight into your ears. So holding the phone near your ear won’t make them squeal.
Anything you watch on your phone or tablet plays in your ears: FaceTime, YouTube, streaming shows, movies. Certus Max does not connect to the TV on its own. In the room, it works as a hearing aid and makes voices on the TV clearer. So you don’t have to turn the TV up as loud.
Up to 15 hours a day of hearing. Streaming uses more power: about 5 hours of calls or about 6 hours of music. The case recharges the aids 4 to 5 times, so a long day out is covered.
That is exactly who Certus Max is for. The aid sits behind the ear, and only a soft dome goes in the ear. Five dome sizes come in the box. If in-ear aids hurt or fell out, start with a smaller dome.
It does show a little, but it is small. A 4-gram silver-white body sits behind the ear with a thin clear wire. Your hair or glasses usually hide it. If you want a pair that sits fully inside the ear, look at Certus One or Certus Pro.
Yes. Pair it once to their phone and run the hearing check with them: about ten minutes. After that it connects by itself whenever they take the aids out of the case. They can change the volume on the case screen without touching the phone.
Lots of people try AirPods first, and they are good for calls. But the hearing feature needs an iPhone, and the battery lasts about 5 to 6 hours. Everyone can see them, too. Certus Max works with iPhone or Android and gives up to 15 hours a day of hearing. Its case screen shows the left and right volume.
No. You can change the volume and mode on the touchscreen case, and on the aids. The free app adds the five-minute hearing check and the volume for each ear. Pairing for calls is done in your phone’s Bluetooth settings.
Certus Max does not depend on the app: the volume and mode are on the case and on the aids. Your 2-year warranty covers faults, and a real person answers email 7 days a week. 1,489 verified buyers have reviewed it on this page, including critical reviews.
Medicare doesn’t cover hearing aids. Medicare Advantage plans that help usually do it only through their own network of clinics. So most people pay for hearing aids themselves.
Yes. Hearing aids are an eligible medical expense, and you don’t need a doctor’s note. You can pay with your HSA or FSA card. We email an itemized receipt for your HSA or FSA.
A real hearing aid. Certus Max is a certified OTC hearing aid for adults with mild to moderate hearing loss. Cheap amplifiers turn every sound up at once. Certus Max lifts voices, turns background noise down, and streams calls and music into both ears.
No. Certus Max is for mild to moderate hearing loss and everyday situations: conversation, calls, music. For severe or profound loss, hearing aids fitted by an audiologist are the right choice.
Because you are not paying for a clinic. Audiologists quote $4,000 to $7,500 for a pair that streams calls. Much of that pays for the office, the appointments and the fitting fees. Costco is about $1,400 to $1,800 a pair, plus the membership and the trips to the warehouse. Certus Max comes straight to your door, with 90 days at home to be sure it does the job.
Every order ships free, tracked and insured, to your door. Your tracking link arrives by email as soon as it ships.
Email us. A real person replies within 24 hours. If it develops a fault in the first two years, it is repaired or replaced free under your 2-year warranty.
Wear them for 21 days, then email us within 90 days of delivery for a full refund. No restocking fee. Faults are covered by the 2-year warranty.
Wear them on the calls you used to dread, on FaceTime with the grandkids and on walks with music. If they are not right for you, send them back. A return starts with one email.
