V1 Classic

How do I set up my V1 Classic? Setup is one button. 1) Unbox your V1 device. 2) Plug in and charge via USB-C. 3) Press the power button once. 4) That's it. When the light is on, it's working. For optimal operation, place the V1 with the spiral coil facing upwards and the display facing downwards on a flat surface. Recommended spots include under your bed, on your nightstand, in your living space, at your desk, or near a meditation area. What does the V1 Classic actually do? The V1 Classic generates a real, measurable electromagnetic field at 7.83 Hz. That's the same frequency the Earth has produced naturally for millions of years. It uses an internal Mobius coil to create this field in the space around you, so there's nothing to listen to, no headphones, no app, and no sound. It's not an audio device. You simply place it in your room and let it run silently in the background while you sleep, work, or relax. Think of it as bringing the Earth's natural frequency indoors, for the many hours most of us spend inside. How long does the battery last? The V1 Classic is built for long-term, set-it-and-forget-it use. On a single charge, the battery lasts up to several weeks under normal conditions. The V1 runs on a single fixed frequency with no digital display, which makes it very energy-efficient. You can leave it plugged in while running, but most users rarely need to. How much space does it cover? The V1 covers up to 350 sq ft, with the strongest effect within about 190 sq ft. That makes it ideal for bedrooms, home offices, nurseries, or any room where you spend extended time. Placement doesn't need to be precise. Under your bed, on a nightstand, or on a desk all work well. Just place it with the spiral coil facing upward and the display side facing down on a flat surface. What do the lights on my V1 Classic mean? Blue light - Device is working and emitting 7.83 Hz on battery power. Red light - Device is currently charging or the battery is empty. Green light - Battery is fully charged and the device is operating directly via the power cable. No light - Device is off or needs a charge. Is it safe for children and pets? Yes, completely safe for everyone, including babies, young children, and pets. The V1 produces an extremely low-intensity, non-ionizing electromagnetic field (roughly comparable to a typical fridge magnet at close range) and is completely silent, with no heat, vibration, or sound. There's nothing disruptive about having it running in a shared space. Many customers tell us their pets naturally gravitate toward the device, choosing to rest or nap near it when it's on. If anyone in the household has a pacemaker or other implanted medical device, we recommend checking with their doctor first, same as you would with any electronic device. What if something goes wrong with my purchase, or I just don't like it? We've got you covered either way. Every V1 Classic comes with a 1-year warranty against manufacturing defects, so if anything is wrong with your device, we'll replace it. Not feeling it? No problem. We offer 30-day returns. Every order also comes with package protection and tracking, so you'll always know where your device is, and if it gets lost or damaged in transit, we'll sort it out. Can I travel with my V1 Classic? Yes. The V1 Classic is compact and TSA-friendly, and the multi-week battery life makes it ideal for travel. Many customers bring it along for hotel stays, long trips, and adjusting to new time zones. The single-frequency design means there's no setup wherever you are: just press the power button. It charges via USB-C, so any standard USB-C charger or adapter rated for your local voltage will work. Why is it so affordable compared to alternatives? Our mission is Frequency for All. We design, engineer, and sell direct-to-customer. No distributors, no retail markups, no overpriced 'luxury' branding. Every dollar goes into better components, stronger field output, and tighter frequency precision. The result is equal or higher performance than competitors charging 2 to 5 times more. Every device is FCC certified and ships from dedicated warehouses in the US for a fast 2 to 5 day delivery.

V2 Pro

How do I set up my V2 Pro? 1) Unbox your V2 Pro and inspect the contents. 2) Plug in and charge via USB-C. 3) Press the power button to activate the digital display. 4) Your device is ready when the display illuminates. Use the up and down buttons on the top right to adjust the frequency between 0.01 and 999.99 Hz. Use the Mode button on the top left to switch between sine and square waveforms. The current frequency and waveform are shown on the digital display. What does the V2 Pro actually do? The V2 Pro generates real, measurable electromagnetic fields using our Mobius coil and WaveForm engine. Unlike audio apps or sound-based devices, there's nothing to listen to. No headphones, no speakers, no sound. You select a specific frequency on the digital display, and the device creates a silent electromagnetic field in the space around you. The adjustable range spans 0.01 Hz to 999.99 Hz with 0.01 Hz precision, so you can dial in frequencies for sleep, focus, meditation, creativity, recovery, or all-day grounding. It's a wellness and performance tool designed for people who want full control over their frequency environment. How is the V2 Pro different from the V1 Classic? The V1 Classic is a dedicated 7.83 Hz device. One frequency, one button, weeks of battery life. It's built for simplicity and long-term background use. The V2 Pro opens up the entire frequency spectrum. You get an adjustable range from 0.01 to 999.99 Hz, a digital LED display for precise tuning, switchable sine and square waveforms, and a larger coverage area of approximately 250 sq ft. Battery life is shorter (6 to 12 hours depending on frequency) because the display and wider range require more power. But it also works while charging, so you're never limited to battery only. If you want set-it-and-forget-it grounding, the V1 is ideal. If you want to explore different frequencies for different goals throughout your day, the V2 Pro is built for that. What's the difference between sine and square waveforms? Sine waves are smooth and continuous. They're the most natural waveform and ideal for sleep, deep rest, meditation, all-day relaxation, and long background sessions. Most users default to sine for overnight use or calm, grounding environments. Square waves are sharper and more energizing. They deliver a more intense signal, making them better suited for focus, energy, morning routines, or deeper targeted sessions. Think of sine as your evening mode and square as your daytime mode. Both are available on the V2 Pro and can be switched at any time. The V1 Classic runs on sine only. How much space does the V2 Pro cover? The V2 Pro can influence spaces up to 400 sq ft, with the most effective results within about 250 sq ft. The field is strongest closest to the device and gradually decreases with distance. The V2 Pro offers a stronger field and more flexibility than the V1, making it especially effective in larger rooms or open areas. What does the yellow indicator light mean? On the V2 Pro, a yellow light next to the display signifies the device is working as expected. At lower frequencies, the light blinks. At higher frequencies, it stays solid. If the screen enters sleep mode after 60 seconds to preserve battery, the device continues to operate normally with the last selected frequency and waveform. Press any button to wake the display. What if something goes wrong with my purchase, or I just don't like it? We've got you covered either way. Every V2 Pro comes with a 1-year warranty against manufacturing defects, so if anything is wrong with your device, we'll replace it. Not feeling it? No problem. We offer 30-day returns. Every order also comes with package protection and tracking, so you'll always know where your device is, and if it gets lost or damaged in transit, we'll sort it out. Fast shipping, full peace of mind. Is it safe for children and pets? Yes, completely safe for everyone, including babies, young children, and pets. The V2 Pro produces an extremely low-intensity, non-ionizing electromagnetic field (roughly comparable to a typical fridge magnet at close range) and is completely silent, with no heat, vibration, or sound. There's nothing disruptive about having it running in a shared space. Many customers tell us their pets naturally gravitate toward the device, choosing to rest or nap near it when it's on. If anyone in the household has a pacemaker or other implanted medical device, we recommend checking with their doctor first, same as you would with any electronic device. Can I travel with it? Yes. The V2 Pro is compact and TSA-friendly. Many users bring it along for hotel rooms, flights, or adjusting to new time zones. The built-in rechargeable battery means you don't need to be near an outlet, and the adjustable frequency range lets you adapt your environment wherever you are. Whether that's winding down in a hotel room or staying focused in a co-working space.

V3 Max

How do I set up my V3 Max? 1) Unbox your V3 Max and inspect the contents. 2) Charge fully via USB-C before first use. 3) Press the power button to activate the display. The frequency will default to 7.83 Hz on first use, the foundational Schumann Resonance. 4) Use the up and down buttons to fine-tune the frequency in 0.01 Hz increments. 5) Use the quick-jump button to move up by 1,000 Hz with a single click, making it easy to navigate the full kilohertz range. 6) Press the Mode button to switch between sine and square waveforms. On the back of the device, you'll find 5 physical preset buttons. To save your current frequency to a preset, hold any preset button for 2 to 3 seconds. From then on, a single tap recalls that frequency instantly. Most users set their presets around their daily rhythm: morning focus, afternoon energy, evening wind-down, sleep, and one flexible slot. For recommended starting frequencies and protocols, refer to the V3 Max Frequency Library in your included Frequency Guide. What does the V3 Max actually do? The V3 Max generates real, measurable electromagnetic fields using our Mobius coil and WaveForm engine. Like the V2 Pro, there's nothing to listen to. No headphones, no speakers, no sound. You select a specific frequency on the display, and the device creates a silent electromagnetic field in the space around you. What sets the V3 Max apart is the expanded range: 0.01 Hz all the way to 9,999.99 Hz, with 0.01 Hz precision. That's 10 times the range of the V2 Pro, giving you full access to the frequency spectrum for sleep, focus, meditation, recovery, energy, and everything in between. How is the V3 Max different from the V2 Pro? The V2 Pro opened up the frequency spectrum from 0.01 to 999.99 Hz. The V3 Max pushes that ceiling to 9,999.99 Hz, territory no portable frequency device has reached before. It also adds 5 physical preset buttons on the back of the device, so you can save your go-to frequencies and switch between them with one touch. No scrolling, no re-dialing. There's also a quick-jump button that moves you up by 1,000 Hz with a single click, which makes navigating the wider range fast and effortless. Battery life is up to 24 hours on a single charge, and the molded casing has no screws, a cleaner build inside and out. Available in both black and white. Why did you expand the frequency range so much? This was the most requested upgrade from our community. Customers using the V2 Pro kept asking for access to higher frequencies, specifically above 1,000 Hz, where skin resistance drops and the signal reaches deeper structures in the body. The V3 Max was built around that feedback. The expanded 0.01 to 9,999.99 Hz range means you're no longer limited to the lower end of the spectrum. You can explore everything from deep delta sleep frequencies to high-frequency energy and focus modes, all on one device. How do the 5 preset buttons work? Find a frequency that works for you, hold one of the preset buttons for 2 to 3 seconds, and it's saved. From there, one tap switches to that frequency instantly. Most users set their presets around their daily rhythm. One for morning focus, one for afternoon energy, one for evening wind-down, one for sleep, and one flexible slot for whatever they're working on that week. It turns the V3 Max into a device you actually use throughout the day, not one you have to re-configure every session. How much space does the V3 Max cover? The V3 Max can influence spaces up to 250 sq ft. The field is strongest closest to the device and gradually decreases with distance. Combined with the expanded 0.01 to 9,999.99 Hz frequency range and 5 preset buttons, the V3 Max is built for whole-room coverage in living spaces, home offices, bedrooms, and meditation areas. What do the indicators on my V3 Max display mean? The V3 Max has a digital display that shows everything you need at a glance, similar to your phone screen. You'll see the current frequency you're running, which preset is active (if any), the selected waveform (sine or square), the battery level, and a charging indicator when the device is plugged in via USB-C. The display is designed to be readable at a glance, day or night. What if something goes wrong with my purchase, or I just don't like it? We've got you covered either way. Every V3 Max comes with a 1-year warranty against manufacturing defects, so if anything is wrong with your device, we'll replace it. Not feeling it? No problem. We offer 30-day returns. Every order also comes with package protection and tracking, so you'll always know where your device is, and if it gets lost or damaged in transit, we'll sort it out. Can I travel with the V3 Max? Yes. The V3 Max is compact (100 by 100 by 18 mm, 210 g) and TSA-friendly. The up to 24 hour battery means you can get through long flights, hotel stays, and time zone shifts without needing to be near an outlet. It charges via USB-C, and you can use it while it's charging, so you're never locked out of a session. Is it safe for children and pets? Yes, completely safe for everyone, including babies, young children, and pets. The V3 Max produces an extremely low-intensity, non-ionizing electromagnetic field (around 10 microtesla close to the device, weaker than a typical fridge magnet) and is completely silent, with no heat, vibration, or sound. There's nothing disruptive about having it running in a shared space. Many customers tell us their pets naturally gravitate toward the device, choosing to rest or nap near it when it's on. If anyone in the household has a pacemaker or other implanted medical device, we recommend checking with their doctor first, same as you would with any electronic device.

Frequency Water Bottle

How do I use my Frequency Water Bottle for the first time? Your Water Bottle works as a daily ritual in four simple steps: Cleanse - Remove your crystals from the pod and rinse them under running water. This clears any residue and resets stored energy, giving you a fresh, clean surface for imprinting. Fill - Fill with filtered or spring water. The piezoelectric crystal chamber sits beneath the water without direct contact, transferring vibrational energy through the glass. Hold the bottle for a moment as you fill it. Some researchers believe water responds not just to minerals, but to the intention behind how it's handled. Imprint - Place your bottle next to your Schumann V1, V2 Pro, or V3 Max for 20 to 30 minutes. The device's electromagnetic field passes through the crystals, deepening the imprint into your water. Drink and recharge - Drink within 24 hours for the freshest structure. To maintain your crystals, place them in sunlight or moonlight once a week. This is a practice used for centuries to restore natural mineral energy. What does this bottle actually do? The crystal chamber at the base contains natural quartz-family crystals that are piezoelectric, meaning they convert energy into an electrical charge. This vibrational energy transfers into your water through the glass without the crystals ever touching the water directly. The result is water that's been exposed to a continuous, subtle resonance from the minerals beneath it. Place it next to a Schumann device, and that resonance gets amplified by the device's electromagnetic field. Do I need a Schumann device to use it? No. The bottle works on its own. The piezoelectric crystals transfer vibrational energy into your water the moment you fill it. A Schumann device amplifies the effect by adding a measurable electromagnetic frequency to the environment around the crystals. Think of the bottle as the foundation and the device as the upgrade. Can I use any crystals? The bottle is designed for our crystal pods specifically. Every crystal in our lineup belongs to the quartz family, which means they're all naturally piezoelectric. That's what makes the bottle work. We currently offer Clear Quartz, with more options launching soon. Does the water stay structured forever? We recommend drinking your water within 24 hours of filling for the freshest result. Like any natural process, the effect is strongest when it's recent. Just refill, let it sit, and repeat. It becomes part of your daily routine. How long should I leave the bottle next to my Schumann device? 20 to 30 minutes is a good window. Some users leave it longer. There's no harm in that. The crystals respond to the electromagnetic field continuously, so more time just means more exposure. Is this the same as crystal water bottles on Amazon? Most crystal bottles on the market drop loose stones directly into the water. Ours keeps crystals in a sealed pod, no direct contact with your drinking water. The piezoelectric chamber design is built to transfer energy through the glass, not to soak stones in your drink.

EMF Nano Shield Sticker

How do I apply my EMF Nano Shield Sticker? Application is simple. Make sure the surface where you're applying the sticker is clean and dry. Peel the backing, then place the sticker on the back of your device or surface and press firmly for a few seconds to secure the adhesive. The sticker is designed for permanent placement and is not intended to be repositioned once applied. Apply it to the back of your phone case, the underside of your laptop, the back of your router, or any non-screen surface of the device you want to harmonize. Do not apply directly onto screens or display panels. What does the EMF Sticker do? The Schumann EMF Sticker is designed to harmonize electromagnetic radiation from the personal electronics you use most. Phones, laptops, tablets, routers, baby monitors. It uses a multi-layer nano construction with 24K gold and absorptive mineral layers to convert chaotic EMF peaks into more coherent waves. It doesn't block your signal or drain your battery. It works passively and silently within a local range of about 30 cm, specifically to reduce localized electromagnetic exposure right where you're holding or sitting near a device. Will it affect my cell service or Wi-Fi? No. The sticker does not block, disrupt, or interfere with any connectivity. Your calls, Wi-Fi, Bluetooth, and data all work exactly the same. Unlike signal-blocking products that kill your reception and drain your battery trying to reconnect, our sticker harmonizes the radiation without affecting device function. You won't notice any change in how your phone or laptop performs. How long does it last? The sticker's energetic imprint is permanent. It doesn't wear out, degrade, or need recharging. Physically, it lasts as long as the adhesive layer stays intact, which is typically several years. It's ultra-thin (under 0.5 mm), fits under most phone cases without adding bulk, and requires zero maintenance. One purchase, permanent use. Where should I apply it? Apply the sticker to a clean, dry, non-screen surface of the device you want to harmonize. The back of your phone case, the underside of your laptop, the back of your router, the back of your tablet, or one cup of your Bluetooth headphones. Do not apply directly to screens or display panels. Once placed, the sticker is designed for permanent placement and is not intended to be repositioned. Does it work without a Schumann device? Yes. The sticker provides localized EMF harmonization entirely on its own, no pairing required. That said, the sticker and the Schumann devices serve different purposes. The sticker works locally on the specific electronic device it's attached to. The V1 and V2 Pro create a low-frequency field across your room or workspace. Combining both gives you localized device protection plus a broader grounded environment, but each works independently. Can I use more than one sticker? Absolutely. Many customers apply one sticker per device. Phone, laptop, router, tablet. Some also double up on higher-output devices like Wi-Fi routers or smart TVs for added coverage. If you use multiple electronics throughout your day (most people do), a multi-pack lets you cover your whole setup rather than just one device. Where can I find the user guide? Every device ships with a printed Quick Setup Guide and Frequency Guide in the box. You can also download the full digital User Guide and Frequency Guide from your account at theschumann.com or by reaching out to support@theschumann.com.

Care, Storage & Travel

How do I clean my V1, V2 Pro, or V3 Max? Wipe the casing gently with a soft, dry or lightly damp microfiber cloth. Do not submerge any device in water, do not run them under a tap, and avoid abrasive cleaners or solvents. The casing is made from premium ABS and acrylic and stays clean with minimal effort. Always make sure the device is unplugged before cleaning. How do I clean my Frequency Water Bottle? The Water Bottle is hand-wash only and not dishwasher safe. The high heat and pressure of a dishwasher can damage the glass, the bamboo, and the seal of the crystal pod. To clean: rinse the glass with warm water and a mild, unscented soap, then let it air dry. Both the bamboo cap and the bamboo base can be wiped down with a damp cloth and dried thoroughly before reassembly. Avoid soaking the bamboo in water for long periods, as that can cause swelling or warping over time. The crystals inside the pod do not need cleaning, just refresh them in sunlight or moonlight once a week. How do I clean my EMF Nano Shield Sticker? The sticker is IP67 waterproof and designed to handle daily wear. If it picks up dust or fingerprints, wipe it gently with a soft, slightly damp cloth. Avoid harsh solvents, abrasive cleaners, or scratching the surface. How should I store my products when not in use? Store your Schumann device upright on a flat, stable surface where it won't get knocked or dropped. Avoid extreme temperatures, direct sunlight for long periods, and damp environments. If you're traveling or putting your devices away for an extended period, charge them once every few months to keep the battery healthy. The Water Bottle should be stored in a place where it can't be knocked over or shattered. Can I travel with my Schumann device? Yes. All three devices are compact and TSA-friendly, and many of our customers travel with them regularly for hotel rooms, flights, and time zone adjustments. Devices with built-in rechargeable batteries typically need to stay in your carry-on luggage rather than checked baggage. This is standard policy for most major airlines, but rules can vary by carrier and by region. We recommend checking your specific airline's lithium battery policy before you fly. What about international voltage and adapters? All Schumann devices charge via USB-C, so any standard USB-C charger or adapter rated for your local voltage will work. The devices themselves don't require a region-specific power supply. Note that we do not include international plug adapters in the box, so if you're traveling outside your home region, plan to bring or purchase a standard USB-C-compatible adapter for the country you're visiting. Can I take the Frequency Water Bottle on a flight? Yes. The Water Bottle itself is allowed in carry-on luggage, but it must be empty when going through airport security. You can fill it after passing security or once you're at your destination. The crystal pod stays inside the bottle and does not need to be removed for travel.
