See & hear the size difference
Nine sizes hand-hammered side by side in the same Patan workshop, sorted small to large. All voiced to the same Theta-band sustain. The only difference you'll hear is pitch and decay length, not quality.
Smallest (8 cm). Palm-sized. Travels in a carry-on. Bright tone, quick decay.
Small (9.5 cm). Nightstand companion. The size most people start with.
Midsize (12 cm). Desk or bedside reset. The most-ordered overall.
Large (15 cm). Living-room piece. Deeper fundamental, longer sustain.
Largest (20 cm). Family or shared-space sound. Lowest pitch, longest tail.
The video also includes four sizes we don't sell: 8.5, 11, 13, and 17.5 cm. Listen and you'll hear why. Each sits too close to its neighbour in our line, same fundamental band, near-identical sustain. We kept the five above because each one is spaced far enough from the next to be a meaningfully different instrument, not a cosmetic variant.
Hit play and listen to all nine in sequence.
From People Who Tried Everything Else First
Anatomy of an Acoustic Regulator
You're Not Anxious. Your Nervous System Is Stuck.
You wake at 3 a.m. with a jolt — body leaden, mind running. You sleep eight hours and wake feeling like you slept zero. You sit in the parked car for ten minutes before you can open the door. Your bloodwork came back "normal." You did not feel reassured.
You've tried the apps, the supplements, the sleep-hygiene rules. And every time, you end up right back where you started — exhausted, scattered, and quietly terrified that this is just who you are now.
It's not.
Clinicians call this autonomic dysregulation: the sympathetic nervous system gets stuck on, and the parasympathetic — the "stand-down" system — can't engage. You're not lazy. You're not undisciplined. You're a person whose body has forgotten the involuntary signal for safe.
The bowl is what gives that signal back.
Four Centuries of Hand-Hammered Acoustic Craft
Our bowls are forged in the Patan district of Kathmandu Valley by Newari craftsmen of the Tamrakar and Kansakar lineages. The same families have done this work continuously since the 16th century, supplying monasteries and household kitchens across the Himalayan foothills with bells, alms bowls, butter-lamps, and offering vessels.
Each bowl in our line is hand-hammered by a seventh- or eighth-generation smith using the same hammer-and-anvil annealing method his grandfathers used. The metallurgy is real, the lineage is real, and we work with these craftsmen to tune each bowl's acoustic profile to the 4–8 Hz Theta band documented in modern EEG research.
This isn't a product "launch." It's an old craft, calibrated to modern measurement. Each bowl is tested for sustain and overtone density before it leaves the workshop.
Old craft. Modern calibration.
Why a Passive Sound Succeeds Where Apps Fail
Meditation apps ask you to use your mind to fix your mind. That's like asking a broken engine to repair itself while driving.
The Kyimolung Handcrafted Singing Bowl works through a fundamentally different mechanism: passive acoustic regulation. Three documented effects run in parallel the moment it rings.
1. Frequency Following Response. When the auditory cortex processes a steady rhythmic pulse, neuronal firing patterns synchronise to it. Published EEG work has measured spectral magnitude increases of up to 251% in the Theta band during sound-bath exposure.
2. Vagal stimulation. The bowl's fundamental tones (50–200 Hz) propagate through air and bone. They register as low-frequency mechanical input on the vagus nerve — the body's biological brake pedal.
3. Cymatic resonance. Pour a thin layer of water into the bowl and strike it. The surface organises into visible standing waves. Your body is roughly 60% water. The same waves are running through your tissue while it plays.
The mechanism is mathematical and involuntary. It works whether you believe in it. Whether you can sit still. Whether you have ever once successfully meditated.
More From People Who Tried Everything Else
“HR for nine restaurants, two teenagers at home, a husband who works nights. I'd been running on adrenaline for as long as I could remember. The wake-up call was forgetting my own son's birthday-party plans mid-conversation with him. Three months in, my Sunday-night dread is finally gone. My daughter actually asks if we can 'do the bowl' before homework now. That's the part I didn't expect.” - Megan H.
“Logistics is a business of constant fires. I'd been waking up at 4 a.m. thinking about Monday for fifteen years. My wife bought me this for my birthday. I told her it was nice and put it in a drawer. Six weeks later, one bad night, I pulled it out, hit it, sat for fifteen minutes. Slept the rest of the night. The fires are still there. The 4 a.m. wake-ups aren't.” - Marcus W.
“Peri-menopause turned my sleep into a war zone. 2 a.m. wake-ups, hot flashes, brain that wouldn't quit. My doctor offered HRT and I wasn't ready. The 2 a.m. wake-ups didn't stop entirely, but they're shorter and I fall back to sleep — which is everything. I feel like myself in the mornings again.” - Maggie O.
Frequently Asked Questions
Why this isn't another meditation gadget
Why this isn't another meditation gadget
Most "mindfulness tools" are just repackaged apps, timers, or another subscription. They rely on your willpower — the very thing that's already exhausted — to work.
The bowl works in the opposite direction. It's a passive acoustic regulator: an external rhythmic sound that entrains your brain involuntarily, whether you're focused or wandering. The Frequency Following Response engages on its own. The vagus nerve fires on its own. The cymatic waves run through your tissue on their own.
No app. No voice telling you to breathe. No quiet room you don't have. No 30 uninterrupted minutes. Sit, strike the bowl, breathe normally — twelve minutes is enough.
This is not mysticism. It is acoustic physics and polyvagal biology — measurable in EEG and HRV data, documented across thirty-plus years of research, used continuously in Patan workshops for four centuries.
How do I use the bowl?
How do I use the bowl?
No mantras. No counting. No "doing it right." Hold the bowl in your palm or rest it on the cushion that ships with it. Strike the rim once with the leather striker, then run the striker slowly around the outer rim with light pressure — like stirring honey. Sit. Breathe normally. Let it work. Twelve minutes is enough. If your mind wanders, fine. The mechanism does not require you to focus.
Where are your bowls made?
Where are your bowls made?
Our bowls are forged in the Patan district of Kathmandu Valley, Nepal, by Newari craftsmen of the Tamrakar (copper-workers) and Kansakar (metal-workers) lineages. The same families have done this work continuously since the 16th century — supplying monasteries and household kitchens across the Himalayan foothills with bells, alms bowls, butter-lamps, and offering vessels. Each bowl is hand-hammered by a seventh- or eighth-generation smith using the same hammer-and-anvil annealing method his grandfathers used, then tuned and tested for overtone density before it ships. Nothing is poured into a mould. Nothing is mass-produced. The asymmetry from hand-hammering is what generates the binaural beating effect — and the entire mechanism falls apart without it.
What size bowl should I buy?
What size bowl should I buy?
We offer five sizes, $59.99 to $239.99 USD. Smaller bowls run higher and brighter; larger bowls sit lower in the body and run longer. The underlying physics is the same — every bowl in the line is tuned to produce beating frequencies in the 4–8 Hz Theta band. Pick the one that fits your room and your budget. If you're buying for more than one room, the bundle discount (10% off any two, 20% off any three) applies automatically at checkout, and you can mix and match across sizes.
How is this different from meditation?
How is this different from meditation?
Meditation is top-down: it asks your conscious mind to direct your attention. The bowl is bottom-up: an external acoustic rhythm entrains your brain involuntarily, whether you're focused or wandering. If meditation has ever felt impossible — too much sitting still, too much arguing with your own thoughts — that's the difference. The bowl bypasses the part of you that has been trying to focus for years.

90-Day "Any Reason" Return
90-Day "Any Reason" Return
Resetting an autonomic loop that has been running for years takes time. That's why we don't ask you to "love it in 7 days or send it back."
Use your bowl for a full 90 days. Twelve minutes most weekdays is enough — give your nervous system the time it needs to rebuild the parasympathetic response. If, after three months of honest use, you don't feel a measurable change in the way you wind down at night — we'll refund every cent, including shipping. No forms. No questionnaire. No hassle.
We keep the carbon, you keep the bowl. Easier for everyone.
What is your return policy?
