headset features

16-channel EEG.

16 electrodes strategically placed to provide optimum coverage of the brain and to capture all the signals.

Dry-Electrodes designed for comfort

Polymer Ag/AgCl electrodes are industry-standard non-polarizable electrodes used in EEG-based clinical measurements. These electrodes are popular for low electrode-skin impedance and low noise. A 15-pin dry EEG electrode is easy to use and comfortable to wear.

Group 4734

Active Electrode system.

Active Electrode System integrates an amplifier with high input impedance, low noise and good electrode offset rejection. It locally amplifies and buffers μV-level EEG signals before driving any cabling, leading to lower noise levels compared to conventional passive electrodes.

Group 4839

Connectivity modes.

Connects via Bluetooth 5.0 and also via Wi-fi to ensure low latency and fast data transmission. The headset is also preconfigured to connect to the SDK hosted on Microsoft Azure.
