A gentle pulse, quietly settling the mind.

Harmonic Frequencies are gentle, steady rhythms the SOTA Bio Tuner sends through two Ear Clips on your ear lobes, supporting an inner sense of calm and balance. Some days you feel a little out of tune — a few quiet minutes can bring you back.

Your mind and body speak the same language

Harmonic Frequencies speak the same electrical language your mind and body already use to communicate — the same quiet signals behind every thought and sensation.

A constant conversation

Your brain and body never stop communicating. Every thought, sensation and shift in how settled you feel travels between them — a quiet exchange running every moment of the day.

And that link is electrical

Those messages move as faint electrical signals — every nerve impulse and heartbeat is a tiny electrical event, measured in millionths of an amp. The mind-body connection isn’t a metaphor; it’s literally electrical. This is textbook biology.

What makes it “harmonic”

A frequency is simply how many times something repeats per second — measured in Hertz. It becomes harmonic when a base frequency is joined by its natural relatives (its multiples), all in neat proportion — the difference between an ordered chord and random noise.

Supported, never forced

Harmonic Frequencies sit in that same gentle range your body already uses. Rather than overriding anything, they work within your mind-body connection — supporting an inner sense of calm, balance and tranquility.

What is Bio Tuning?

The Bio Tuner works by delivering gentle harmonic frequencies — a clear, steady rhythm passed through the ear lobes. Here’s what that looks like in practice.

A clean, steady rhythm

At its heart is one calming base frequency — 1,000 Hz, gently pulse modulated at 111.11 Hz. It’s not a sound you hear: it is a quiet, even electrical rhythm your body can settle alongside.

Delivered through the ear lobes

Two Ear Clips sit on the lobe of each ear, close to the jaw. The gentle frequencies pass quietly through the skin — nothing you hear, nothing inside your ears. Once they’re on, you carry on with whatever you’re doing.

Gentle and yours to tune

The current sits in the microcurrent range — about the magnitude your body already uses — felt as a soft, pleasant buzzing. Try any of the modes, turn the dial to where it’s as comfortable as you want.

What to expect from each mode.

Every mode is designed for the same thing — gentle, comfortable relaxation. What changes is how each one feels. None is more beneficial than another, so there’s no wrong choice: explore and use whichever suits you best.

MODE 1 Ready

The secret is consistency, not intensity.

Think of Bio Tuning like sleep, movement or quiet time — daily, consistent use is what builds the benefit. Some people notice a difference right away; for most, it takes at least 30 days of daily use.

A sample routine. Not a rule.

Everyone’s approach looks different. Here’s one way it could work — yours might look nothing like this, and that’s entirely the point.

  1. Morning

    Start your day

    A calm 20 minutes to begin

    Clip on, settle into a comfortable level in Mode 1 and let one session run while you ease into the day. Many find it a steadying way to start.

  2. Midday

    While you work or read

    Quietly in the background

    Slip the unit onto the Arm Band or keep it on your desk and run a session while you carry on. It’s discreet enough to fade into whatever you’re doing.

  3. Evening

    Wind down

    Read in bed and relax

    An evening session pairs naturally with reading or resting before sleep. This is the moment many users say they enjoy most.

  4. Anytime

    Explore the modes

    Find the rhythm that suits you

    There’s no wrong choice. Try different modes from time to time and keep whichever feels best. Try modes 4-6 if you’d like something gentler.

Common misconceptions.

New things can feel unfamiliar. Here’s what people often assume — and what’s actually true.

  • Myth

    “A higher mode number is stronger or better”

    Reality

    No mode is more beneficial than another. Higher numbers aren’t “stronger”. Modes 4-6 actually have a gentler feel than 1-3. The numbers simply mark different rhythms and pulse widths to explore.

  • Myth

    “I need to turn it up high to get the benefit”

    Reality

    The unit never needs to be at maximum — comfort is the goal, not intensity. With repeated use you may feel the buzzing less, which is normal; you can nudge the dial up if you wish.

  • Myth

    “If I don’t notice anything the first week, it isn’t for me”

    Reality

    Wellness builds slowly. It may take at least 30 days of daily use before you notice much; the greatest benefits often come with continued use over time. The people who feel the most are usually those who stay consistent.

  • Myth

    “A little unit like this won’t last”

    Reality

    With simple care the Bio Tuner is built for years of use — it carries a 3-year warranty. The only part that needs replacing is the conductive rubber on the ear clips and those are a quick, low-cost replacement.

How to use the Bio Tuner.

  1. Placing the Ear Clips on the ear lobes

    Step 1 — Set up and clip on

    Place one Ear Clip on each ear lobe, with the Rubber Electrode toward the back of the lobe, as close to the jaw as possible.

  2. Turning the Bio Tuner on and easing the intensity dial up

    Step 2 — Turn it on and ease the dial up

    Switch the unit on — the lights flash and it starts in Mode 1. Turn the intensity up gradually to a comfortable, pleasant buzzing. Never jump straight to maximum; comfort is the goal.

  3. Pressing the Mode button to explore the six modes

    Step 3 — Choose a mode and relax

    Press the Mode button to explore the six modes and settle on whichever feels best. Then carry on — read, work or rest. Reduce the intensity before switching modes, then re-adjust.

  4. Relaxing while a timed Bio Tuner session runs

    Step 4 — Let the session run, then build

    Each timed session is about 20 minutes; the unit beeps and goes into sleep mode when it’s done — turn it off to save the battery. Start with one session a day for 3-4 days, then build toward two or more. Drink plenty of water.

Your Bio Tuning routine

Start here
  • Start with 1 cycle (20 minutes) a day, whenever it suits you
  • Keep it to one cycle for the first 3-4 days so your body can adjust
  • Turn the intensity up gradually to a gentle, pleasant buzzing — never to discomfort

Important

If you’re on psychiatric medication, or have a neurological condition or seizures, check with your health practitioner before you begin.

Tips this week

  • Clean your ear lobes first — wipe away skin oils before clipping on — clean skin carries the current far better.
  • Wet the electrodes every time — dampen the conductive rubber with water (or aloe vera / conductive gel) before each session, and re-wet it if it ever feels prickly.
  • Just settle in on Mode 1 — no mode is “better” than another — this week is only about getting a feel for the sensation.
