An EEG-guided headband that listens to the brain, and answers with personalized 40 Hz sound.

Research-stage concept

A quiet instrument for the mind.

A noninvasive headband and a companion app that blend music with personalized 40 Hz sound, in a closed loop.

Design

01Halo

One continuous sweep of satin titanium, shaped to the brow.

From temple to temple, the titanium never breaks. A single light line marks the band.

02Crown

Soft where it rests.

A knit cushion rolls over the top edge and meets the forehead first.

03Contacts

Dry contacts listen across the forehead. No gel.

Champagne contacts sit in soft foam, low on the inner band, where the halo meets the skin.

04Fit

Rests at the temples. Settles behind the ear.

Drawn around a head first, then shaped to it: a halo across the brow and slim arms that tuck behind the ear.

05Layers

Every layer, considered.

Textile, titanium, foam and glass, each meeting the next on a clean line.

  1. Knit crown
  2. Dry contacts
  3. Titanium halo
  4. Light line
  5. Titanium arm
  6. Smoked-glass module
  7. Graphite ear rest

How it works

One closed loop.

A research-stage design that listens, forecasts and adapts, so the sound follows the person.

  1. 0105

    Sense

    Dry contacts read the brain’s electrical rhythm, continuously.

  2. 0205

    Interpret

    A causal model reads what has already happened to forecast what comes next, including when the brain may stop responding.

  3. 0305

    Personalize

    The stimulus adapts to the person, not to a fixed schedule.

  4. 0405

    Deliver

    40 Hz sound, woven into music.

    Demonstration

    Five seconds of a soft chord with a 40 Hz pulse, at low volume.

  5. 0505

    Adapt

    Every response informs the next. The loop closes.

Interface concept

Calm on the surface. Personal underneath.

Sessions shaped by mood and cognitive load, and a caregiver view that keeps family close.

From research to product

It started with one person.

  1. The question

    I was nine, and it was my grandfather. He forgot my name and looked at me like a stranger.

    More than eight years of classical and jazz piano run through everything that followed.

  2. The research

    Closed-loop EEG with personalized 40 Hz auditory stimulation, building on MIT’s 2016 gamma-stimulation research. A causal temporal-convolutional network reads continuous EEG and forecasts phase–amplitude coupling, so the sound can adapt in real time.

  3. The prototype

    Weeks spent optimizing real-time latency. Then a pilot with 18 seniors in assisted-living facilities.

  4. The company

    Harmoniq turns that research into a product: a headband and an app, designed together.

From the founder

When my grandfather’s memory began to fade, he lost his words, but he could still feel music.

Amaar, Founder

For every name worth remembering.

Harmoniq is building toward proactive cognitive care that’s as routine as a blood-pressure check.

The aim: use AI, sound and personalization to support and study the mind.
