A DRY-EEG INSERT FOR YOUR HEADPHONES

Your focus,
measured.

Name: NeuroFocus EEG Insert
Brand: NeuroFocus
Price: 49.99 USD
Availability: PreOrder

One channel of real brain signal, read from an insert in your earpad and scored 0–100 while you work. An instrument, not an app: it shows you when focus held, when it broke — and what broke it.

HOW IT WORKS

How a brain signal
becomes a focus score

1 · Read

Real EEG

Dry electrodes in the earpad read an around-ear EEG signal — no gel, no prep, no second device. Just the headphones you already wear all day.

2 · Compute

Engagement index

We compute an established engagement index — beta (13–30 Hz) against alpha (8–12 Hz) plus theta (4–8 Hz), after Pope et al. (1995). It rises as you lock in and falls as you drift.

3 · Score

Live overlay

That index becomes one number from 0–100. When it craters halfway through what was meant to be deep work, you’ll see it — and see exactly what pulled you out.

SUPPORTED BY

Focus is a signal. We made it visible.

LOCKED IN

While you work

One number at the edge of your screen. When it craters, that's a context switch you'd never have noticed — the kind that costs the next twenty minutes.

SESSION REVIEW

After the session

The honest trace of your day: when focus held, when it broke, and what each interruption actually cost. Hours worked is a vanity metric — this isn't.

TECHNICAL DEPTH

The signal is real.

A focus score is only worth trusting if the signal under it is real EEG — not noise. So we anchor ours in a peer-reviewed engagement index (Pope et al., 1995), estimated in our proof of concept from a single around-ear channel.

SINGLE-CHANNEL EEG · AROUND-EAR

One dry electrode in the earpad reads an around-ear EEG channel — the same passive, voltage-only sensing principle as a lab EEG. No gel, no forehead straps.
ENGAGEMENT INDEX · β / (α + θ)

An established EEG engagement metric (Pope et al., 1995) — the number the overlay tracks.
THE BERGER EFFECT

Alpha power (8–12 Hz) rises when you close your eyes and falls when you open them — the oldest result in EEG, and a clean check that a device is reading your brain.
WHERE WE ARE · SINGLE CHANNEL

Today's proof of concept reads one around-ear channel, checked against a consumer NeuroSky headset. The production design scales toward eight channels.

BUILT IN THE LAB

How we actually build it —
and how we test it.

Real science only ships on real hardware. Hands-on bench tests, real wearing sessions — every shot here is our own lab and our own prototypes, not a render.
