EMFs are All Around You, All the Time
Your phone. Your laptop. Your router, and your neighbor's router. The cell tower you can't see from the window.
None of it is going away. So the question isn't how to avoid EMFs anymore. It's how to feel steady in the middle of them.
That's the question Harmoni was built to answer.
Your body runs on electrical impulses. Dr. Martin Pall, PhD, Professor Emeritus of Biochemistry and Medical Science at Washington State University, has published 26 papers exploring how manmade electromagnetic fields may interact with that system.
- 3.8 billionsmartphones, and millions of cell towers to support them
- 200 billionmore connected "smart" devices emitting microwave radiation
- 50,000"wireless" satellites set to blanket the earth in microwave radiation
The Frequencies
You Never Chose
Your WiFi. Your neighbors' WiFi. The smart TV, the baby monitor, the speaker on the counter, the 5G tower down the road. Each one adds its own signal, and together they fill the rooms your family lives in with a field of chaotic, man-made frequencies.
You already filter your water and read the labels on what your kids eat. The frequencies in your home belong on that list too.
- Supplements
- work on your chemistry
- Exercise
- works on your body
- Harmoni
- is made for the frequencies around you
Harmoni was made to help neutralize the chaotic frequencies from modern tech and create healthier environments, for you and the people you love.
200+ Frequencies
in Every Pendant
Every Harmoni Pendant is imprinted with a library of more than 200 frequencies before it ships. Nothing in it runs on a battery or a chip. Four families make up the core of the library, from the Earth's own frequency up to the terahertz band.
-
7.83 Hz
The Schumann resonance
The Earth's own background frequency, the natural resonance between the ground and the upper atmosphere. Physicist Winfried Otto Schumann predicted it in 1952, and it's often called the Earth's heartbeat.
-
174–963 Hz
The nine Solfeggio tones
A nine-tone scale tied to the old solfège syllables (Ut, Re, Mi, Fa, Sol, La) and used widely in sound and meditation practices today.
-
MHz
Megahertz frequencies
Higher frequencies, measured in millions of cycles per second, imprinted alongside the lower tones.
-
THz
Terahertz frequencies
The band between microwaves and infrared light, measured in trillions of cycles per second.
The nine Solfeggio tones
Tap a tone to hear it.
Tone descriptions reflect how sound and meditation traditions describe each frequency. They are not medical claims. The pendant itself is silent; the buttons above let you hear each tone.
Meet the Harmoni Pendant
The Harmoni Pendant is a breakthrough in EMF protection, perfected by over a decade of testing.
It has been used by industry experts, doctors, health practitioners, top authors, professional athletes, celebrities, and thousands of everyday people looking for a solution to mitigate EMF radiation exposure.
Feel the difference
A wearable made for modern life
We're surrounded by screens, routers, and devices. Harmoni was created for people who want to feel a little more grounded in the middle of it. No batteries, no electronics, no maintenance. Just activate it and wear it.
Built for calm
Designed to support your body's sense of balance
Harmoni was designed to support your body's own sense of balance, especially in high-EMF environments: home, office, or on the go.
Wind down with ease
Part of an evening routine
Many people build Harmoni into their evening routine, to bring a greater sense of calm alongside their other nightly habits.
Wear it anywhere
Made for everyday life
Designed to go with you, through your workday, your workout, your commute, without a second thought. It's wellness support that moves with you.
A simpler kind of wellness
No apps. No charging. No settings.
Harmoni takes a non-electronic, low-effort approach to supporting your day-to-day sense of wellbeing.
Thoughtfully made
Individually activated before it reaches you
Each Harmoni Pendant is carefully designed to reduce feelings of EMF-related stress. Wear it as a necklace to bring you calm.
Grounded in research
Backed by ongoing, evolving research
Harmoni has been the subject of an internal pilot study exploring how the body responds to everyday electromagnetic environments. We're continuing to invest in research as the science develops.
An open-label pilot evaluation was conducted to assess the efficacy of the Harmoni Pendant in reducing stress and the impact of electromagnetic fields (EMF). The evaluation was conducted by eight doctors from across the United States, spanning specialists in various fields, using Heart Scientific HRV technology, which measures stress and nervous system health.
The preliminary open-label pilot evaluation found:
Inner calm
Heart rate variability increased significantly
Heart rate variability, or HRV, is an increasingly well-researched way to measure how stressed-out or calm someone is.
Lower stress
Designed to reduce feelings of EMF-induced stress
Participants reported reduced feelings of stress from EMFs, along with a greater sense of overall wellness, while wearing the pendant.
Preliminary results from a small, open-label pilot evaluation, not a controlled clinical trial. Individual experiences vary. Before-and-after images are illustrative. The Harmoni Pendant is not a medical device.
“I love mine.”
What doctors and wearers say
Practitioners who recommend Harmoni to their patients, and people who wear it every day.
“My Harmoni pendant allows me to lower my stress while protecting me from harmful electromagnetic frequencies. I wear it everyday and feel AMAZING!”
“I did my own scan and showed that it does truly affect my heart rate variability. I have a really high level of stress in my job and raising 4 children. I really felt it had a calming effect on me and I'm more level headed to get through my day easier. I'm recommending to my patients.”
“EMF radiation is a silent form of stress on our body that over time has a destructive impact on our health. Being healthy in the 21st century depends upon our ability to mitigate and adapt to this onslaught of radiation. Harmoni pendants help protect us from EMF radiation and give us greater resilience in body and mind!”
“The Harmoni Pendant is a tremendous tool to help balance the flight or flight state that we so often find ourselves in these days. The first time I wore mine, I could feel my body relaxing and my thoughts clarifying. My 13 year old son says he feels lighter when he wears it. It's my new favorite gift for friends and family!”
“EMF and new wireless technology exposure is a top health concern of mine. Wearing the Harmoni Pendant gives me peace of mind.”
“I couldn't be more grateful to have this easy EMF solution for me and my family! I always notice a HUGE difference on days we wear our pendants.”
“When I harmonized it to my body, I could totally feel myself relax. I almost fell asleep. It really works. Super little tuning fork for the body.”
“I've been feeling so much better. But forgot to wear it yesterday and definitely had a dip in energy and a bit of a headache. Back on today. Feeling much more centered and content.”
“Just less than 2 weeks being harmonized with the Harmoni pendant, I am still in a state of amazement how well I feel!”
“It's truly amazing. It helps me feel extremely relaxed and tired in the evening and want to fall asleep, which is very new for me.”

Questions, answered
Still wondering about something? Email support@harmonipendant.com and a real person will get back to you.
How do I use it?
Put it on. Each pendant is individually activated before it ships. The card in your box walks you through a short activation step, and the same steps live at harmonipendant.com/activate. After that there is nothing to charge, update or remember.
What frequencies are in the pendant?
More than 200, imprinted before each pendant ships. The core of the library is the Schumann resonance (7.83 Hz), the nine Solfeggio tones (174 to 963 Hz), and families of megahertz and terahertz frequencies. The pendant has no battery and no electronics, so it doesn't emit sound or a wireless signal.
Will it interfere with my phone or WiFi?
No. Harmoni is a passive pendant. It doesn't block, jam or change the signal from your devices, so your calls, data and WiFi work exactly as they did before.
Which size should I choose?
Small is 20mm across, about the size of a nickel. Large is 25mm, close to a quarter. Small is the popular pick for a finer chain and a lighter feel; Large reads a little bolder. Both come on a matching chain in a gift box.
What are the EMF Card and Sticker in the bundles?
The EMF Card is a thin gold card, about the size of a credit card. Set it down once in the room you use most, like your bedroom, home office or car. The EMF Sticker is a small, round gold sticker for the back of your phone, laptop or tablet. Both carry the same library of 200+ imprinted frequencies as the pendant, with no batteries, no charging and no app.
What is it made of?
The core pendant is surgical-grade stainless steel, which is hypoallergenic and nickel-free. Gold and rose gold pendants are the same pendant plated in 18K gold or 18K rose gold.
Is there research behind it?
Harmoni has been the subject of an internal, open-label pilot evaluation run by eight US doctors using Heart Scientific HRV technology. Participants reported feeling less stressed and a greater sense of overall wellness. It's a preliminary evaluation, not a controlled clinical trial, and we're continuing to invest in research as the science develops.
Is the Harmoni Pendant a medical device?
No. Harmoni is a wellness accessory. It isn't intended to diagnose, treat, cure or prevent any disease. If you have a medical condition, talk with your doctor.
What if it isn't for me?
Wear it for 60 full days. If you're not thrilled with how you feel, mail it back and we'll refund every penny you paid. Email support@harmonipendant.com to start a return.
How fast does it ship?
Orders ship from our US warehouse within a few business days. Single pendants ship for a flat rate; bundles ship free within the US.
