A clinic price buys professional fitting and aftercare, which is worth it for some people. If you mainly need the device, this is the difference.
Photographed by owners
Their own photographs, the day the box arrived.
Much easier to follow conversations at home, and I like that my ears still feel open.
Comfortable with my glasses and simple enough once I got used to the controls.
Works well in quiet places. Busy restaurants are still a little difficult for me.
I’m asking my wife to repeat herself a lot less during dinner.
The fit took me a few days to get right, but now I wear them most afternoons.
I like being able to hear conversations without having something pushed inside my ear.
Very comfortable for several hours, and phone calls have been easier to follow.
Owners
My wife reads little bits of the newspaper to me over breakfast. With the B02, I’m catching more without asking her to start over. Been using them most mornings for three weeks now.
My son helped with the app, but I’ve managed the volume myself since then. Lunch with my brother was easier to follow. Still had trouble when the table behind us got loud.
I kept waiting for the clips to bother me with my glasses. Wore them through lunch and a card game without needing to take them off. That’s a welcome change from my last pair.
I like not having an earpiece pushed inside my ear. The charging case lives beside my bed now, which helps me remember. Getting the left clip settled still takes an extra try some mornings.
Why people switch
Almost every complaint people have about hearing aids — the soreness, the whistling, the hollow voice — comes from one design decision: a tip pushed down into the ear canal.

No tip, no dome, no mould. The canal stays open all day.

Seal an ear and your own voice gets trapped inside it. An open canal lets it out.

Feedback is cancelled in the chip, not by pushing a tip in harder.
In everyday use






How to use it
No appointment, no prescription, no clinic visit. Everything happens at your kitchen table.

Plug it in until the display reads 100. A full case lasts about a week.

Hook it over your ear. Nothing pushes in. Left and right are marked.

Sit somewhere quiet and follow the tones in the app. It tunes both ears to your result.

Quiet, outdoors, noisy or automatic. Change it in the app, or with the remote in the box.
Where it helps
Not the quiet of a living room. These are the rooms where people with mild to moderate hearing loss stop joining in.
Not a showroom, not a booth. The rooms you actually struggle in, for a hundred days.

The B02 hooks over your ear, with the speaker resting in the bowl. Your glasses sit above it.
Allow a few days to get used to the routine.
Actual size

About as wide as a US quarter. Each side weighs 5.6 grams, roughly a teaspoon of sugar.
It sits in front of your ear canal, never inside. Visible up close, but discreet from a distance.
No tip inside. No seal trapping your voice. Built-in feedback control helps reduce whistling.

An open design leaks more sound, so the chip cancels the squeal before you hear it.

Automatic switches for you. Or pick quiet, outdoors or noisy yourself.

Holds 60+ hours in reserve. Fifteen minutes buys about two more hours.

If one goes missing, the app shows its last known location on a map.
The optional app shows its last known location and can make it flash when within Bluetooth range.
Location updates need the app and Bluetooth range. This is not live tracking.
How noticeable is it?
Not a close-up. Both of these are shot from where the person opposite you would be sitting.
We will not tell you it is invisible. It sits on the outside of your ear, so someone looking for it will see it. At conversational distance most people do not notice it, and it reads as an earbud rather than a hearing aid.
Help after it arrives
The app's five-minute check sets a starting profile. If it still does not sound right, a Flysound fitter adjusts it for you remotely — no clinic visit and no fee. Here is exactly how that works.

These are over-the-counter hearing aids. They are not suitable for severe or profound
hearing loss, which needs a prescription device and a hearing professional.

Flysound sent review units to these channels. The opinions, and the measurements, are entirely their own.
Why trust us
No silicone tip. No dome. No mould. The speaker sits in the bowl of your ear.
Where these come from. These are the B02 owner reviews supplied to us by Flysound, the manufacturer, published here in full — the 3 one-star and 7 two-star ratings included. We have not filtered or reordered them. We cannot independently verify each reviewer, so weigh them alongside the things you can check for yourself: the certifications, the independent channels below, and the 100 days.
Each review sorted by subject, with the average rating of that group. This is a more useful picture than one number.
The highest-rated subject in the whole set. The battery number on the front of the case does a lot of work.
The question people ask before buying scores above the average, not below it.
The group this page is written for, and they rate it higher than average.
Streaming is the bonus people did not expect. It also drains the charge faster.
Most got there. Several said to allow an evening and not to rush it.
The most written-about subject here, at 59 reviews. It helps. It does not solve it. Read this group before you decide.
The lowest-rated subject on this page, and one of the most written about. Most settle within a fortnight; a few never found a comfortable position.
Second lowest, and the smallest sample here at 16. If this is your main problem, read these first.
The short version. People who wanted ordinary conversation back, who wear glasses, and who had given up on a previous pair rate it highest. Comfort and loud rooms sit at the bottom. No open-ear device shuts a room out.

It matters, because this design addresses some of those reasons and not others. Find yours below — and if none of them is your reason, this may not be your device.
That is a different problem and we are not going to pretend this solves it. An open ear leaves the canal clear, which is why it is comfortable — but it also means the device cannot shut the room out. Expect the person beside you to be clearer and the far end of the table to stay hard work. Owners who wrote about restaurants and crowded rooms rated the B02 4.1 out of 5 — near the bottom of our own review data. If a loud restaurant is the main thing you need fixed, see a hearing professional before you spend anything; no over-the-counter device, this one included, reliably solves it.
No. Over-the-counter hearing aids are designed to be bought and fitted without a prescription by adults 18 and over with perceived mild to moderate hearing loss. The app runs a short hearing check that tunes the device to you. That check is for setup, not a medical diagnosis.
Yes. The B02 sits on the outside of your ear, so it is visible in the way a small earbud is visible. It is not an invisible in-canal device and we would rather say so than have it arrive as a surprise.
At normal volume, someone beside you will not make out your call or TV audio. In a silent room at high volume, someone very close may hear faint sound.
It pairs with an Android phone or iPhone over Bluetooth 5.3 for calls and audio. Televisions vary — some pair directly, many need a small Bluetooth transmitter plugged into the TV. Check what your set supports before you rely on it.
Yes. You have 100 days from delivery to request a return, whatever the reason. You receive a full refund to your original payment method, with no restocking fee.
Contact us directly, not the factory:
Once approved, send them back within 7 days.
Yes. Return the original box with the hearing aids, case, cables and papers.
No. We email you a prepaid return label. If you have already paid for postage, we refund it. Start your return with us so we can arrange it.
Your refund arrives 5–10 business days after your return is checked in.
No. It is rated IP55, which means it resists dust, sweat and rain. Do not shower, swim or bathe in it, and do not submerge it.
Yes. The arm of your glasses and the arm of the B02 share the same strip of skin behind the ear, so the order matters: put the hearing aids on first and settle your glasses over them. Taking both off at once is where they catch — glasses off first. Expect it to feel awkward for the first few days while you work out your own routine.
The clip hooks over the outer ear rather than wedging into it, and an anti-loss cord is in the box that links both earpieces behind your neck. If you are doing something where losing one would be a disaster, use the cord.
There are no tips or domes to swap — the fit comes from where you seat the clip, so you adjust it by position rather than by parts. Ears are not symmetrical, so it is normal for one side to settle straight away and the other to take more fiddling. If one side still bothers you after a week, call support before you give up — it is usually placement.
They are sold and priced as a pair and are tuned as a pair, and the price is for both ears. We are not going to claim a single-ear mode we have not verified — if you need one ear only, ask support on (302) 271-0679 before ordering. Note that hearing loss in one ear only is a reason to see a doctor first, not a reason to buy an over-the-counter device.
Up to 12 hours of ordinary listening, which covers breakfast through the evening for most people. Streaming audio over Bluetooth continuously pulls that down to roughly 6 hours, so a day of television through the aids is different from a day of conversation. The case holds 60+ hours in reserve, a full charge takes about 2.5 hours, and 15 minutes in the case buys you about 2 more hours if you have been caught out. The practical trick is to charge them at the same time as your phone, so it becomes one habit rather than two.
Day one is the hardest, and it is normal. Expect your own voice and ordinary household sounds — cutlery, paper, the fridge — to seem loud at first while your brain recalibrates to hearing them again. The common mistake is changing too many settings on the first day: find a comfortable volume and leave it alone. Start with an hour or two at a time rather than a full day, and build up. Give it a fortnight before you judge, and do not judge it on one noisy dinner. If something still feels wrong after that, call us — that is what the 100 days and the phone number are for.
No. Your pair arrives pre-set and ready to use. The included remote adjusts volume and listening modes. The optional app adds a five-minute hearing check and fine-tuning.
A hundred days from the day they arrive. If they are not right, email us for a prepaid label — we cover the return postage ourselves — and send the pair back complete. Full refund, no restocking fee.

The Flysound OpenEar Comfort (model B02) is an over-the-counter hearing aid for adults 18 and over with perceived mild to moderate hearing loss. It is not a treatment for any medical condition and does not restore hearing. “FDA registered” means the manufacturer and device are listed with the FDA; it is not an FDA approval or endorsement. The B02 is rated IP55 — it resists dust, sweat and rain and should not be submerged. Individual results vary. Some photographs on this page are digitally created illustrations of the product in use. If you have ear pain, discharge, sudden hearing loss, hearing loss in one ear only, or a history of ear surgery or a perforated eardrum, consult a doctor or audiologist before using any hearing device.
