I am selling one used Wearable Sensing DSI-24 Dry EEG Headset, originally purchased in October 2015. The cap is in good condition, with one electrode (P3) just slightly bent out of position but still functioning. Can be easily repaired back into place. EEG Acquisition through native DSI Streamer software (included), as well as modules in NeuroGuide (can be included if asked).
Please email jessica@jtolentino.com if you are interested!

DSI 24 Features
The DSI-24 is a research grade wireless EEG headset designed for rapid application of 21 sensors at locations corresponding to the 10-20 International System. Its main features include:
- Self-donned and ready to record EEG in under 5 minutes
- Comfortable for wearing continuously over 8 hours
- Portable design suitable for light ambulation in office or lab environment
- 21 sensors positioned according to the 10-20 International System
- Continuous impedance monitoring
- BlueTooth wireless transmission with sampling at 300Hz
- Hot-swappable Li-ion batteries allow continuous operation
- 8-bit digital trigger input
- Adjustable to fit a wide range of headsizes (54-62cm in circumference)
The DSI-24’s practicality, portability, and high signal quality opens the door to taking numerous applications that were previously limited to lab environments to more naturalistic settings. Such applications include:
- Neurofeedback
- NeuroErgonomics
- NeuroEconomomics / NeuroMarketing
- NeuroEducation
- Augmented Cognition
- Brain Computer Interfaces
- Biometrics
- Cognitive Stress or Workload Monitoring
- Psychological Research
- Sports Peak Performance Training
