How accurate is the Circl Headset?

Circl is a world leader in mobile EEG digital signal processing.

The Circl headset measures your brainwaves more accurately than a heart rate monitor measures your heart rate. In technical terms, we detect brainwave data with an amplitude to 3 millionths of a volt with millisecond accuracy.

The technology is based on 60 years of academic research and over 10,000 peer-reviewed research journals. This is one of the most well-researched methods of measuring changes in our brains and our ability to process information.

While it’s not a medical device, it’s designed to provide reliable insights that help you understand and optimize your mental state. This level of accuracy was previously only available in a lab setting.
