The IDUN Guardian is the most ergonomic EEG monitoring device and scalable brain analytics platform.
Our combined hardware and software accurately monitor and interpret brain waves during sleep and wakefulness, offering valuable decoded user insights to enterprise customers and end users through our API.
From brain data to insights.


Our Hardware
Since earbuds are already socially accepted and widely used, they are the ideal modality for a non-invasive BCI. Our brain-sensing earbuds measure EEG (Electroencephalogram), which is the electrical signal produced by the brain. The Guardian Earbuds are unobtrusive, ergonomic, and have been optimized for sleep.

Our Software
Perfectly blended with our EEG Earbuds, the IDUN Guardian Software provides a straightforward and efficient tool for EEG data management. It offers a user-friendly, no-code interface for the easy recording, storing, and downloading of data via the web.
For customers who prefer a coding environment, the platform includes a Python SDK and ensures real-time data synchronization via LSL.

Earbuds are already ubiquitous
Everybody wears earbuds, imagine getting insights from brain activity without bulky equipment.


Benchmarking
Not just another wearable, the IDUN Guardian Earbuds stand tall against clinical gold standards, marking a leap forward in the realm of real-time, comfort-focused EEG monitoring. Here are some examples of how the IDUN Guardian compares against the PSG for common sleep markers.
