EEG Headsets

Clean. Fast. Mobile

EEG Systems

The Dry Sensor Interface (DSI) series integrates QUASAR’s revolutionary dry electrode technology that acquires clean EEG signals, without the need for skin preparation or gels, and without compromising on signal quality. The DSI EEG signals are comparable to those obtained from wet electrode systems and are resistant to electrical and motion artifacts. The DSI wireless EEG headsets are designed for speed and ease of use, comfort, and mobility in real-world environments. This world leading dry electrode technology is revolutionizing EEG use in research, neurofeedback, brain-computer interfaces, neuromarketing and more.
