The room goes quiet.
Your head doesn't.
Husvel holds one steady tone in the room — a wind-down cue your body learns to recognise. Anything from 0.01 to 100,000 Hz. Headphones in the box for the nights someone's asleep beside you.
What a frequency actually does.
You can't feel a tone through a screen. So here's the next best thing — the device, running, unedited.
It's the only proof you have
Nobody can hear your product before buying. A single unedited take does more than every paragraph on this page combined.
Show, don't claim
Film what the device does. Don't caption it with what it does to a body — that's the line between a demo and a claim.
Unedited beats polished
Say so in the caption. "Filmed in-house, one take, no cuts" is worth more than a colour grade.
You've tried the obvious things.
You've downloaded the sleep apps, the white noise apps, the breathing apps. Your phone is still on the pillow at 1am.
You've bought the supplements. They work while you take them and stop when you don't.
You've done the "no screens after nine" thing for four days in a row, twice.
You've been told to just relax, which is the least useful instruction ever given to someone who can't.
A cue. Every one of them asks you to do something differently. A wind-down routine works because of repetition, not effort — the same signal, in the same room, at the same hour, until your body starts recognising it before you do. That's the one job Husvel has.
It's a ritual, not a treatment.
Husvel doesn't do something to you. It gives you a consistent cue — and a consistent cue is what most wind-down routines are missing.
Turn the dial
Anywhere from 0.01 Hz to 100,000 Hz. Eight shortcuts on the front, the rest in the printed handbook.
Put it down and walk away
Bedside table, desk, a shelf across the room. Speaker for the room, headphones for when you're not alone in it.
Same tone, same time
The effect is cumulative. By the end of the first week, switching it on starts to feel like the end of the day.
Why it isn't a $12 gadget.
Four things you can check for yourself, and one of them is the reason it sounds different from everything else at this price.
100+ frequencies. One dial.
Every one described by how it sounds and when people reach for it. Tap any card to hear it.
The rest are in the printed handbook that ships in the box.
Hear it from them.
Five things in the box you didn't pay for.
Not upsells. They ship with every unit, in the same box, at no extra cost.
Your first week, honestly.
Most pages skip this. Setting expectations properly is why people keep the thing.
You'll notice the tone more than anything else
Normal — new sound in a familiar room. Run the dial through a few settings, find the one you dislike least, leave it there.
It starts to disappear
You stop actively hearing it within a few minutes. That's when it becomes useful rather than interesting.
Switching it on becomes the signal
The tone matters less than the consistency. Same sound, same hour, and your evening has a shape it didn't have before.
Decide
If it hasn't changed your evenings, send it back for a full refund. No explanation required.
Against the alternatives.
Including the one where they win.

What people actually say

We made 300. Then we'll see.
This is the first production run. When it's gone we'll order more, but the launch price is tied to this batch — not to a clock on the page. No countdown timer here, because that would be a lie.
Sleep on it. Sixty times.
Use it every night for two months. If your evenings haven't changed, email us and send it back — we refund in full and you don't need to explain yourself.
We'd rather have the device back than have your money.
Before you buy
What does 0.01 to 100,000 Hz actually mean?
It's the full span the device can output — seven decades. You can only hear roughly 20 Hz to 18,000 Hz, and that upper limit drops with age. Below 20 Hz there's nothing audible: those settings run silently. The dial on this page is logarithmic for the same reason, otherwise everything usable would sit in the last inch.
Which frequency should I start with?
528. It's where most people end up and it's the least distracting of the eight shortcuts. Move around during the first week and keep whichever disappears fastest.
Are headphones included?
Yes, in the box. Plug them into the 3.5 mm socket and the speaker cuts out — useful when someone's asleep next to you or you're on a plane. Nothing to pair or charge.
Is the handbook a PDF?
No — a printed book that ships in the box. It's the difference between owning something and downloading something, and it's the reason people use the device on night one instead of leaving it in the drawer.
How long should I run it for?
Start with 20–30 minutes as you get into bed. Plenty of people leave it on all night at low volume — that's fine too. There's no dose to get right.
Will it wake my partner?
At normal volume it sits under the level of a desk fan. And if they're a light sleeper, that's what the headphones are for.
Is it safe around children and pets?
It's a speaker playing a tone — nothing more. Keep it out of reach of small children like any other electrical device.
Does it need wifi, an app or an account?
None of the three. Plug it in, turn the dial, done. There's no microphone and it doesn't connect to anything.
What if it does nothing for me?
Send it back within 60 nights for a full refund. Some people notice a difference in the first week and some never do — the guarantee exists so you're not carrying that risk.
Give your attention somewhere to rest.
Sixty nights to change your mind, and your phone stays in the hallway.
