Sense the signal.
A Neurable EEG headset senses tiny electrical signals at the surface of the head. These signals provide a changing view of activity, rather than a reading of your thoughts.

Brain activity, reflected through sound. The intended loop keeps sensing and listening on a nearby Mac. An optional iPhone companion can start, watch, and save a session. This website is an illustrated concept, not a live instrument.
EEG meets everyday listeningIndependent researchOptional iPhone companion
What if listening
became a feedback loop?
Your brain is always changing. Our idea is to reflect some of those changes back through sound, creating an opportunity to study how the brain learns from its own activity.
Reflect through sound.
A nearby Mac is intended to look for changes in the signal. Its intended feedback is a brief, subtle change in the music you’re hearing.
Explore what changes.
The research question is whether the brain can learn from that feedback without deliberate effort. There’s no score to chase or “perfect” state to perform.
This is the intended Mac-local experience. The iPhone is an optional companion for controls and records. Today’s development screens show that companion in progress. Live headset timing and training benefits are still being evaluated. The pictures on this page are illustrative.

and a quieter change in sound.
The intended session keeps sensing and listening close together: an over-ear neuro headset, a Mac mini that evaluates changes, a large screen for the simulated timeline, and a phone companion for controls and records. This picture is an illustrated concept, not a live instrument.

1 of 4 · Signal arrives
The headset senses brain activity.
Sensing cushions at the ear pick up small electrical activity at the surface of the head. In this illustration a sample trace is on its way to the Mac. It is not a live reading of your brain.
Press Explore the loop to walk the intended path. Hear music feedback in the listening demo below.
Stage buttons accept arrow keys. Pause and replay are always available from the keyboard once a control is focused.
Mac processing, music feedback, and phone controls are the intended architecture. On 8 September 2026 a raw Mac-to-iPhone relay of headset samples was verified on a local network. Qualified live feedback, calibrated timing at the ear, reliable inference of cognitive state, and a training benefit have not been established.
This is a development concept and does not diagnose or treat. Listen to the music demo below to hear the intended feedback.
Without JavaScript the four stages stay visible below. The picture still shows the headset, compact Mac, simulated screen, and phone companion.
- Signal arrives. Sensing cushions pick up electrical activity at the surface of the head.
- Mac evaluates. A nearby Mac is intended to look for changes and decide whether the music should dip.
- Music softens. The intended feedback is a brief duck or mute of music you already chose.
- Companion records. The phone is intended to start, watch, and save the session while the Mac keeps the time-critical work.
Listening, under a closer lensMore happens

in a moment.
Choose music or video. Turn on “Demonstrate ducks & mutes” to hear the music dip in volume or briefly fall silent, for a different length each time.
The music keeps its place and returns smoothly after each change. No tones, clicks, or other sounds are mixed in. Watch the volume envelope and compare it with what you hear.

Our goal is to explore feedback outside conscious effort. This timed illustration lets you compare sight and sound; it does not measure what your brain detects or demonstrate a training benefit.

For people who
are curious about
their own minds.
Everyday explorers
A new idea for people interested in mindfulness, music, and personal discovery.
Thoughtful early adopters
A chance to help shape a more human experience of brain technology.
Research collaborators
A shared question about feedback, learning, and how to measure what matters.
An idea worth testing.
With care.
Neurofeedback and music-based feedback are active areas of research. They give us reasons to explore, and good reasons to be precise about what we know.
Explore the researchA real field of study.
Researchers have studied how information about brain activity can be returned through visual or auditory feedback.
An open question.
Whether this particular approach supports learning outside conscious effort remains a question for controlled testing.
A clear distinction.
A working app demonstrates software. Evidence of training benefit requires separate studies with meaningful comparisons.
A few things
to know.
Curiosity comes with questions. These are a good place to start.
More help and contact detailsCan I download the app now?
The Noticing Mind is in development. A public App Store or TestFlight release is not available yet. Email James about early access or explore the current app screens.
Will I need a Neurable headset?
Yes. Live brain feedback requires a Neurable EEG headset, sold separately. We’re developing the app around the Neurable MW75 Neuro. See the headset and buying options on Neurable’s website.
Live headset support is still in development. The website sound demo works without a headset because it does not read EEG.
Does it read my thoughts or change my brain with electricity?
No thought-reading capability is being claimed. EEG senses electrical activity through external electrodes. The intended feedback is sound; the app does not deliver electrical stimulation to your brain.
Does the brain really self-correct before I notice?
That is part of the idea we want to investigate, rather than an established result of this product. Some research explores learning without deliberate control, but it does not establish a universal “before consciousness” deadline or prove that our app changes habits.
Is this a treatment or a replacement for medical care?
No. The current app is experimental, and clinical benefits have not been established. It is not offered to diagnose or treat a medical condition or to replace professional care.
Is this NeurOptimal?
The Noticing Mind app is an independent project. It is not NeurOptimal, is not endorsed by Zengar, and makes no equivalence or superiority claim. If you came here about an existing in-person neurofeedback session, contact James about sessions.
