Sound mode (with headphones or speaker): 15–20 minutes per session, up to 1–2 times a day, at a gentle volume.
Silent mode (PEMF only, no headphones): completely safe to run all day or overnight. Many customers leave it on their nightstand while they sleep.

From 0.01 Hz to 100,000 Hz. The full spectrum used in frequency healing. That includes every Solfeggio tone, every Rife frequency, every brainwave range (delta through gamma), and the Schumann resonance (7.83 Hz). If a frequency exists, your Calminity can generate it.

The device generates specific frequencies through Electromagnetic Frequency Technology (EFT) or sound (when connected to audio equipment). We recommend our complete kit, which includes everything you need: the generator unit, necessary cables, anti-radiation earphones and a protective case. Of course no additional purchases required.

Yes, you can play any frequency between 0.01 Hz and 100,000 Hz. The included Frequency Healing Guide Booklet tells you exactly which to use for sleep, pain, focus, parasites, tinnitus, and more, but you're free to experiment with any frequency that resonates with you.

Two ways, working together:
A pulsed electromagnetic field (PEMF) - a silent, gentle field that extends about 5 feet around the device and passes through your body without you needing to touch it.
Audible sine waves - delivered through the included earphones or any speaker, for more focused sessions.
You can use either method on its own, or both at once.

Frequency healing isn't a painkiller - it works gradually, at the cellular level, and most customers report noticing the difference within 3–4 weeks of consistent daily use, and the results tend to compound the longer you stick with it. If you don't feel a change in 90 days, return it for a full refund. You take no risk; we do.

Yes. The frequencies are gentle, drug-free, and non-invasive. Many customers actually keep the device running near pets and grandchildren for the calming effect. For young children and animals, we recommend shorter sessions and adult supervision.

Many customers report meaningful relief after using 174 Hz daily for 2–3 weeks. It's the frequency most associated with easing joint and muscle tension. Results vary, which is why every order is covered by our 60-day money-back guarantee. If it doesn't work for you, you can return it.
