QuietOn 3 Specs: Tiny Earbuds for Noise-Free Sleep – Ozlo

It’s late, the neighbor’s dog won’t stop barking, and someone’s snoring is rattling the walls. Most people have been there, staring at the ceiling, wishing for silence. That’s where the QuietOn 3 earbuds come in. They’re not your typical earbuds - no music streaming or fancy apps here. Instead, they’re built from the ground up to hush the world around you. Curious about what makes them tick? This article digs into the nuts and bolts of the QuietOn 3, from how they’re made to what they can do, all based on the real details out there.

What Are the QuietOn 3 Earbuds?

The QuietOn 3 earbuds are super small devices built to block noise, like a snoring partner or the hum of traffic outside. They’re not your typical earbuds; there’s no Bluetooth or fancy controls here. Instead, they focus on two things: physically blocking sound with their fit and using active noise cancellation (ANC) to zap away even more noise. Think of them as earplugs with a tech twist, made to fit snugly and last through the night.

They come from a company called QuietOn, based in Finland, with the actual manufacturing happening in Poland. The idea started years ago when one of the founders was stuck in a loud airport and craved some peace. That sparked a mission to create something small yet effective, and after a couple of crowdfunding rounds on Indiegogo, the QuietOn 3 was born.

How They’re Built: Design and Materials

Tiny Size, Big Purpose

These earbuds are seriously small, each one weighs just 1.8 grams. That’s lighter than a paperclip! The whole package, including the case and extras, comes in at 150 grams, and the charging case itself is 59 grams. Compared to something like Apple AirPods, they’re noticeably tinier, with a sleek, curved shape that’s meant to sit flush in your ear. The dimensions of the packaging are 12 x 12 x 4.6 cm, so it’s compact enough to toss in a bag or keep on your nightstand.

What They’re Made Of

The QuietOn 3 earbuds are put together with a mix of materials: hard plastics like PC-ABS, PMMA, and polycarbonate for the body, plus polyurethane rubber for the foam tips. There’s also some stainless steel and a touch of gold in there, mostly for the charging contacts and little details like the light guides in the case. The foam tips come in four sizes - extra small, small, medium, and large, so you can find the right fit for your ears.

Fitting In Your Ear

The design is all about slipping into your ear without sticking out too much. For most people, the earbud sits in the concha (that little hollow part of your outer ear) between the crus of helix and the antitragus, fancy terms for the curves around your ear. The slim shape means it doesn’t press hard against your ear canal or stretch anything out, which is a plus if you sleep on your side. You roll the foam tip between your fingers to squish it, pop it in, and give it a slight twist to lock it in place. Once it expands, it creates a seal that helps block sound even before the ANC kicks in.

How They Handle Noise

Two Layers of Quiet

The QuietOn 3 earbuds tackle noise in two ways. First, there’s the physical seal from the foam tips, which stops a good chunk of sound from getting through, like traditional earplugs. Then, there’s the active noise cancellation, which uses tech to sample outside noise and cancel it out with opposing sound waves. This combo works across a wide range of frequencies, but it’s especially good at knocking down low-pitched sounds, like the rumble of an engine or that deep snoring you might hear next to you.

Low Frequencies Are the Star

Data from QuietOn shows these earbuds really shine in the 200-500 Hz range, think of that as the “snoring mountain” zone where a lot of disruptive low-end noise lives. Compared to regular foam earplugs, the QuietOn 3 doubles the noise reduction in this area. It’s not about masking noise with white noise or music; it’s about making those sounds disappear so you’re left with silence.

No Extra Sounds, Just Quiet

Unlike some devices that play sounds to cover up noise, these earbuds don’t add anything. There’s no background hum or nature tracks here, it’s all about creating a calm, empty soundscape. That’s a deliberate choice, keeping things simple and focused on noise reduction alone.

Power and Charging Details

Battery Life That Lasts

Each earbud has a 17mAh lithium-ion battery built in, giving them up to 28 hours of use on a single charge. That’s more than enough to get through a night (or three) without needing a recharge. The charging case has its own 200mAh lithium-ion battery, which can juice up the earbuds about three times from empty to full before you need to plug it in. QuietOn suggests charging the case once a week if you’re using it regularly.

Charging Setup

The case charges via a USB-C port on the back, no wireless charging here, just a straightforward cable setup. A USB-C cable comes in the box, with a standard USB-A plug on the other end to connect to a power source. When it’s plugged in, a faint green light glows near the port to let you know it’s getting power.

Lights and Indicators

The case has some small LEDs to show what’s going on. Three lights above the USB-C port tell you how much charge the case has left. On the front edge, two more sets of three LEDs show the battery status of each earbud when they’re docked. It’s a simple way to keep tabs on power without any guesswork.

Using the QuietOn 3: How It Works

No Buttons, No Fuss: One thing that stands out is how basic the operation is. Take the earbuds out of the case, and they turn on automatically, no buttons to press or apps to fiddle with. Pop them back in the case, and they shut off and start charging. It’s about as plug-and-play as it gets.
Checking If They’re On: Since there’s no power switch or light on the earbuds themselves, figuring out if they’re working can be a bit tricky. QuietOn’s solution? Put the earbud in your ear, hold the case close, and slowly pull it away. If you hear a faint click, they’re on. It’s an odd little trick, but it does the job.
Side Sleeping Friendly: Thanks to their small size and low profile, these earbuds don’t dig into your ear if you’re a side sleeper. The slim design avoids putting pressure on the wrong spots, so you can roll over without feeling like something’s jabbing you.

What’s in the Box

When you open up the QuietOn 3 package, here’s what you’ll find:

The Earbuds: Left and right QuietOn 3 earbuds, ready to go.
Charging Case: A compact case with a hinged lid and built-in battery.
Foam Tips: Four pairs in extra small, small, medium, and large sizes.
