FLYSOUND B02 Review: Ear Clip OTC Hearing Aids Tested on the Windiest Beach on the Gold Coast
The wind's coming straight off the water, waves going, and someone next to me is trying to tell me something. Normally that's the moment I'm going "sorry, what was that?" — a windy beach eats people's voices, and you end up nodding along pretending you heard. But I've got the FLYSOUND B02 in, and the voice is sitting right out in front of the wind. I still know I'm at the beach. I'm just not losing the person next to me. If your hearing's down even a little, a beach like this is one of the hardest places there is to hold a conversation — so let me show you how that's even possible.
Today we're testing the FLYSOUND B02 — the new rechargeable Bluetooth over-the-counter hearing aids in the ear clip style, where the clip sits over the top of your ear rather than behind it or down the canal. I've reviewed FLYSOUND before: the Pure Hear Pro H8, a classic behind-the-ear pair you'd hand to a parent or grandparent, and the Nature Pro H9, a sportier earbud-looking one for streaming and all-day wear. My dad David came on for those and gave his honest take as someone with genuine hearing loss. The B02 is a different device again, so I'm judging it entirely on its own merits — working from home, out and about, taking calls, streaming music, and down at the beach here on the Gold Coast.

01What Is the FLYSOUND B02?
The FLYSOUND B02 is a pair of rechargeable Bluetooth over-the-counter hearing aids in an ear clip design. The clip goes over the top of your ear, so there's no lump sitting behind it and nothing jammed down your ear canal. A small nozzle carries the sound in, and you get four sizes in the box so you can get the seal right.
Inside, the chip runs a frequency range of 250Hz up to 6,000Hz with a maximum output of 110dB SPL. In plain English: it lifts the softer speech sounds — the consonants that go missing first when your hearing drops — without turning the whole world into a shouty mess. That's the line between an actual hearing aid and a cheap amplifier, and it's the bit worth paying attention to.
02Comfort First: The All-Day Fit
Before any of the clever stuff — comfort. Because if a hearing aid annoys you, you take it out, and a hearing aid in a drawer does nothing for anyone. I had these in most of the day working from home at my parents' place, and I honestly forgot they were on while I was filming. No pressure points, no hot spots, none of that blocked-up feeling.
The four nozzle sizes matter more than people think. Small, medium, large and extra large — get the right one, get a good seal, and the sound is heaps better for it. It also killed the whistling feedback completely; I didn't get a single squeal out of these. Once the right size was in, I wore them for hours without thinking about it.
03Working From Home: The AI Noise Reduction
Sitting at the desk there's a fan going above me and traffic at the window. What I noticed is that the room sort of steps back, and the stuff I care about stays clear. That's the AI noise reduction doing its job — it isn't simply turning everything up, it's separating the voice from the background and keeping the voice on top. That distinction is the entire point of a device like this.
It handles the sudden stuff well too. A truck goes past, a gate bangs — the constant background gets pushed down, and the sharp sudden noises get knocked back quickly as well. So you know it happened, you're not missing the world, but it isn't a shock in your ears either. Cheaper units just don't manage that.
04Four Modes, Switched On the Case
There are four listening modes: indoor for quiet conversations and TV at home, outdoor for traffic and being out and about, a dedicated TV mode, and a wind noise mode which — living on the Gold Coast — gets a serious workout. You flick between them with the button on the charging case, and you can turn the volume up and down there too. No app needed.
That's a bigger deal than it sounds. You're not fiddling with tiny buttons behind your ear while you're standing on a footpath. For a lot of people these are aimed at — parents and grandparents who hate fiddly controls — pressing one button on the case is the difference between actually using the modes and never touching them.
05The Beach Test: Wind, Waves & Conversation
This is the test that decides it, because out here hearing aids either earn it or they don't. Down at the water with the ocean going, I flicked to environment mode and the waves came through clear. Press again and it pulls the background right down — almost noise-cancelling. Press again and I'm set up to talk to whoever's next to me. Being able to change that on the spot, depending on where you're standing, is the thing I ended up using constantly.
Then the proper one: wind coming straight off the water, wind noise mode on. The waves and the wind are all still there — I know exactly where I am, and you don't want to be cut off from the world — but the person next to me stays clear. On a beach that windy, that's wild. None of those constant "huh?" and "what was that?" moments. The way the mics are arranged and the wind mode together do a genuinely respectable job of knocking the worst of it back. They're IP68 waterproof as well, so salt air and a bit of weather aren't a worry.
06Bluetooth, Calls & the Honest Battery Numbers
These aren't only hearing aids. There's Bluetooth 5.3 built in, so you can stream music or a podcast and take phone calls straight through them. You're walking along, the phone rings, you answer and talk hands-free — nothing in your hands, and to everyone watching you look like you're talking to yourself. Pairing has been stable and seamless the whole time I've had them, with no dropouts.
Now the battery, straight, because this is where you need the real numbers. You get up to 11 hours on a single charge for normal hearing use — that's a full day, easy. But if you're streaming Bluetooth continuously, music or calls all day, that drops to around 5 hours. That's the honest trade-off. As a hearing aid all day, no problem at all. As all-day wireless earbuds streaming non-stop, you'll be reaching for the case. Which is easy enough — pop them in, they charge, you carry on.
07In the Box & the Anti-Loss Bits
I don't do spec dumps, but a few things in the box are worth naming. Pick them up and they feel solid — light, well made, not cheap or plasticky. You get the two aids, the four nozzle sizes, a USB-C cable, and an anti-loss lanyard.
That lanyard is a small thing I really rate. Clip it on, loop it round your neck, and if one pops out it doesn't vanish into the sand or down the side of the couch. Down the beach especially, that little cord has saved a lot of people a lot of heartbreak. There's also anti-loss tracking, so you can find them if you misplace them — brilliant if you're someone who's forever putting things down and forgetting where.
08The FLYSOUND App & the Hearing Test
This is where you make them yours. The FLYSOUND app runs on iOS and Android and connects easily, and the clever bit is the hearing test — you can run a pure tone audiometry test right there in the app. If you've already got an audiogram from a clinic, you can import that directly instead. Either way it builds a custom hearing profile tuned to your actual ears, rather than a one-size-fits-all setting.
From there you can fine-tune everything: manage the modes, adjust volume left and right independently, dial the whole thing in properly. So you've got two ways to drive them — the case button for quick changes when you're out, the app for proper fine control when you sit down with it. Same as I found with the earlier FLYSOUND models, having both is genuinely useful. Some days you want to press the case; some days you want to tune it properly.
09Standards, Warranty & Support
A couple of things worth knowing, because they matter to the people these are aimed at. They meet FCC international EMC standards, which is real reassurance for a lot of buyers. They're backed by a 12-month warranty and 24-hour customer support, and FLYSOUND run a free remote fitting service — which I always think is a great touch. You're not left on your own with a box and a shrug.

The Verdict & Who It's For
What I love, first and foremost, is the comfort — the ear clip just disappears, and I genuinely forgot I had them in for long stretches. The modes work, and switching them straight off the case button is so simple it's a real win for anyone who hates fiddly controls. The AI noise reduction does the important thing, which is keeping the voice in front of the noise instead of just making everything louder. The beach and wind test impressed me most; that's about the harshest environment there is and they handled it. Add Bluetooth 5.3, IP68, the in-app hearing test and a 12-month warranty and it's a genuinely complete bit of kit.
The catches, honestly: the streaming battery is a real number — around 5 hours of continuous Bluetooth means you're not streaming music all day on these. And like every OTC device at this level, they're for mild to moderate loss, not a medical-grade prescription solution. In really hard moments you'll still miss the odd word. You're not lost in the conversation the way you would be without them, but they're not magic and I'm not going to pretend they are. I should also be straight that this was a day or so of proper testing — beach, walking, working from home — not a six-month long-term wear test.
Who's it for? Anyone who's started turning the TV up higher than everyone else, who's saying "sorry, what was that?" more often, who finds a beach or a busy street a wall of noise — and who doesn't want to spend thousands on prescription aids. The fact you can personalise them with a real hearing test in the app puts them well ahead of a basic amplifier. If your loss is severe, or something has changed suddenly, see an audiologist instead.

?Frequently Asked Questions
What is the FLYSOUND B02?+
The FLYSOUND B02 is a pair of rechargeable Bluetooth over-the-counter hearing aids in an ear clip design — the clip sits over the top of your ear rather than behind it or down the canal. It uses AI noise reduction to keep voices in front of background noise, runs 250Hz to 6,000Hz with a 110dB SPL maximum output, and pairs with the FLYSOUND app on iOS and Android.
Are the FLYSOUND B02 good for wind noise?+
There's a dedicated wind noise mode, switched on the charging case button. I tested it on the Gold Coast with the wind coming straight off the water — the wind and waves are still audible, so you're not cut off from what's around you, but the person speaking next to me stayed clear. It's the test that impressed me most.
How long does the FLYSOUND B02 battery last?+
Up to 11 hours on a single charge for normal hearing use, which is a full day easily. If you're streaming Bluetooth continuously — music or calls — that drops to around 5 hours. The charging case tops them back up, so you pop them in and carry on.
Can you take phone calls with the FLYSOUND B02?+
Yes. Bluetooth 5.3 is built in, so you can stream music and podcasts and take hands-free phone calls straight through them. Pairing was stable throughout my testing with no dropouts.
Do you need the app to use them?+
No. All four modes — indoor, outdoor, TV and wind noise — plus the volume are controlled by the button on the charging case, with no app needed. The FLYSOUND app is there if you want it: it runs a pure tone hearing test, lets you import an existing audiogram, and gives you left and right fine-tuning.
Are OTC hearing aids like these a replacement for prescription hearing aids?+
No, and this isn't medical advice — I'm not an audiologist. The B02 is an over-the-counter device intended for mild to moderate hearing loss. If you have severe loss, sudden hearing loss, pain, dizziness or ringing in your ears, see an audiologist or your doctor. An OTC device isn't the right answer for those, and a professional fitting is.
Are the FLYSOUND B02 waterproof?+
They're rated IP68, so sweat, rain and salt air at the beach aren't a concern. They also come with an anti-loss lanyard and anti-loss tracking, which matter more than you'd think if you're wearing them somewhere you could drop one in the sand.
