The call you dread
The phone rings, and your stomach drops a little.
You press it hard against your ear, then switch to speaker and turn it right up. You still miss the name, the time, the number. Afterward you guess at what was said and hope you got it right.
Face to face you can lip-read and fill the gaps. On the phone there is nothing to read. So you let calls go to voicemail, you ask someone else to call the doctor’s office, and FaceTime with the grandkids becomes a lot of smiling and nodding.
Certus Max puts the call inside both ears. Your phone sends the voice straight to your hearing aids over Bluetooth, clear in both ears, with no speakerphone and no phone pressed to your head.
You’ve probably tried these already. Here’s why they failed:
Speakerphone, turned right up
The whole room hears your call, and the words still blur together.
Cheap drugstore “Bluetooth” amplifiers
They say “Bluetooth” on the box but only pair to an app, or whistle and hiss the moment you hold a phone near them.
Tiny in-ear aids that won’t stay put
If your ear canals are small, in-ear aids pinch, work loose and fall out. Most end up in a drawer.
What actually works: calls streamed into both ears
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.
How it works
How Certus Max puts the call in both ears
A digital hearing aid with Bluetooth built in. Its chip splits sound into 32 bands, so it can lift voices and keep the clatter down. One pair does two jobs: clearer conversation in the room, and calls and music from your phone.
1
Hear: the room, clearer
Microphones behind each ear pick up the voices around you. The 32-channel chip lifts speech and turns background noise down.
2
Pair: once, like earbuds
Pair Certus Max with your phone over Bluetooth once. After that it connects by itself when you lift the aids out of the case.
3
Stream: calls and music, both ears
Phone calls, video calls, music, podcasts and audiobooks play straight into both hearing aids, through the soft dome in each ear.
A certified OTC hearing aid for mild-to-moderate hearing loss, with Bluetooth calls and music built in. Real hearing aid technology, not a gimmick.
Life after Certus
Pick up the phone without thinking twice. Every call.
Calls you used to dodge become calls you look forward to again.
Calls in both ears
The voice plays inside both ears at once, so you hear every word without speakerphone or pressing the phone to your head.
The family, face to face
Video calls with the grandkids come through clearly, so you join in instead of nodding along.
Music and audiobooks on the move
Your playlist, the radio app or an audiobook on a walk, in the car, or while you cook. Up to about 6 hours of music.
Clearer in the room too
When the phone is down, Certus Max works as a hearing aid all day: up to 15 hours of clearer conversation.
What to expect
From the first call to a different daily life
Here is what it feels like, with 90 days to prove it risk-free.
Day 1
Pair once, take a call
Pick a dome size, pair with your phone, run the five-minute hearing check, and call someone. Their voice is in both ears.
Week 1
You stop letting it ring
Your daughter calls, the doctor’s office calls back, the grandkids FaceTime, and you hear all of it. You stop waiting for someone else to make the call.
Week 2
The wire disappears
The thin wire and the small body behind the ear stop feeling new. Most days you forget they are there.
Month 1
Music comes back into your day
Audiobooks on a walk, the radio while you cook, a song in both ears. Clearer conversations around you in between.
Everything you want from a Bluetooth hearing aid
Calls · Music · Every word
A touchscreen on the case
See the left and right volume, the mode and the battery on the case. Change the volume and mode right there, no phone needed.
Fits small ear canals
The body sits behind the ear and only a soft dome goes in the ear. Five dome sizes in the box, so it fits ears that in-ear aids don’t.
Up to 15 hours a day
Up to 15 hours of hearing, or about 5 hours of calls or 6 hours of music. The case refills the aids 4 to 5 times.
“Won’t it be a big plastic thing behind my ear?”
Fair question. It is not invisible, and we won’t pretend it is. Here is what it really looks like.
Small and light: 4 grams
The body 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.
Hidden by hair or glasses
It tucks behind the ear, under your hair or beside a glasses arm. Most people only notice if you tell them.
Silver-white, not beige
Not the beige kind. No thick tube and no molded earpiece, just a small silver-white body and a hair-thin clear wire to a soft dome.
Still unsure?
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.
The honest math
What Bluetooth hearing aids actually cost in the US
Same goal: hear every call. Three very different bills.
Option 1
Private audiologist
$2,000–$6,000+ per pairHearing tests, fittings and follow-up appointments for a Bluetooth pair. The right route for severe or complex loss, and a very big bill for everyday mild-to-moderate loss.
Option 2
A warehouse-club hearing center
Around $1,500 per pair, plus membershipCheaper than a private clinic, but you still book a hearing test and fitting visits. Original Medicare does not pay for hearing aids, so the bill is yours.
Option 3
Certus Max
$499.99 todayA Bluetooth hearing aid that streams calls and music into both ears, with a touchscreen case. At your door in days, set up in minutes, with 90 days to prove itself.

Still deciding if Certus Max fits your day?
Will I really hear phone calls in both ears?
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.
Does it work with my phone?
It pairs with iPhone and Android phones over Bluetooth, the same way earbuds do. Older phones work too, as long as they have Bluetooth. If it will not pair with your phone, email us and a person will talk you through it. If it still won’t, send it back for a full refund.
Will they whistle?
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. During a call the voice goes from the phone straight into your ears, so holding the phone near your ear will not make them squeal.
Can I watch the TV through them?
Anything you watch on your phone or tablet plays in your ears: video calls, streaming shows, YouTube, movies. Certus Max does not connect to the TV on its own. In the room, it works as a hearing aid and makes the TV clearer like any other voice.
How long does the battery last?
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 refills the aids 4 to 5 times, so a long day out is covered.
My ear canals are small. Will these fit?
That is exactly who Certus Max is for. The aid sits behind the ear and only a soft dome goes in the ear, with five dome sizes in the box. If in-ear aids hurt or fell out, start with a smaller dome.
Will people see it?
It is not invisible. It is small and discreet: a 4g silver-white body behind the ear and a thin clear wire, usually hidden by your hair or glasses. If you want a pair that sits fully inside the ear, look at Certus One or Certus Pro.
Can I set it up for my mom or dad?
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 lift the aids out of the case, and they can change the volume on the case screen without touching the phone.
Why not just use AirPods?
AirPods hearing mode needs an iPhone, lasts about 5 to 6 hours, and looks like you are listening to music. Certus Max works with iPhone or Android, gives up to 15 hours a day of hearing, and its case screen shows both volumes.
Do I have to use the app?
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 per-ear volume, and pairing for calls is done in your phone’s Bluetooth settings.
Can I use my HSA or FSA?
OTC hearing aids usually qualify. Keep your order receipt and check with your plan.
Is this a real hearing aid or just an amplifier?
A real hearing aid. Certus Max is a certified hearing aid for mild-to-moderate hearing loss. That is a regulated category with real requirements behind it. Cheap ‘Bluetooth amplifiers’ turn every sound up at once; Certus Max lifts voices, turns background noise down, and streams calls and music into both ears.
Are they suitable for severe hearing loss?
No. Certus Max is for mild-to-moderate hearing loss and everyday situations: conversation, calls, music. For severe or profound loss, a prescription aid is the right route.
How can it cost so much less than the audiologist?
Because you are not paying for the building. A fitted Bluetooth pair costs $2,000 to $6,000 largely due to clinic overheads, appointments and fitting fees. Certus Max comes straight to your door, with 90 days at home to prove it does the job.
How does shipping work?
Every order goes by Fast Tracked Shipping: free, tracked and insured. Your tracking link arrives by email as soon as it leaves us.
What if one stops working?
Email us. A real person replies within 24 hours. If it develops a fault in the first two years, we repair or replace it under your 2-year warranty.
What if they’re not right for me?
Send them back within 90 days for a full refund, with no restocking fee. Covered by a 2-year warranty.
