QUICK 20 Dry EEG Headset

Measuring EEG signals in real-world environments is tough. Unlike a controlled laboratory environment, electrical noise from power lines, computers and other devices easily overwhelms a conventional, unshielded EEG system. Subject movements can induce large amplitude electrical and physical noise overwhelming the tiny EEG signal. To make real-world EEG acquisition possible, the Quick-20 uses a highly optimized combination of sensors, mechanics, and electronics to eliminate unwanted artifacts.

  • Combination of active electrodes and active shielding

  • Resistant against electrical and movement artifacts

  • Real-time measurement of sensor impedance

  • Research-quality EEG amplifier: 24-bit ADC, low-noise, high dynamic range inputs with flexible configuration of sample rates, bandwidth and channels

  • Also available in a Hot-Swappable 8-Channel version


The Quick-20 is a complete portable EEG system in a wearable, lightweight package. Stream data wirelessly via Bluetooth or record to a microSD card.

  • Low-noise dry electrodes require minimum prep and no clean-up

  • Fully wireless: no cords for data recording or triggering

  • Comfortable without any restrictions on subject movement

  • Lightweight and wearable


Like all CGX devices, the Quick-20 is designed to interface with hardware and software tools for advanced neuroscience research.
