Truly wireless earbuds with clinical-grade dry-contact EEG electrodes that read brainwaves in real time and respond with timed audio. In Sleep mode they deliver gentle pink-noise pulses phase-locked to slow-wave activity to deepen restorative sleep; in Focus mode they adapt daytime audio across open-ended, Pomodoro, and alertness-aligned sessions. The companion iOS app handles sleep staging, brainwave analysis, and focus tracking with no subscription required.
