*Compared to existing wet-type research EEG monitors. This product is a research device and cannot be used for diagnostic purposes.
Measurements start in just one minute, just like putting on headphones. No more time spent on setup. No one will interrupt your insights or analysis .
Completely wireless connectivity frees you and your subjects from the lab. The journey to discovering real insights in real-world environments, such as VR, the office, or your home, begins now.
Despite its compact size, it can accept external trigger input and supports LSL (Lab Streaming Layer), allowing synchronization with various events, dramatically expanding the scope of your research.
Attached with flexible dry electrodes.
The pursuit of ergonomic design.
It gently fits onto the scalp, parting the hair. There's no discomfort from the gel or complicated preparation. It's designed based on a wide range of head data. Even when worn for long periods of time, it won't disrupt the subject's concentration. Furthermore, the electrode position can be moved along the centerline of the head, allowing for different measurement points.

External triggers allow synchronization without missing any events.
ERP analysis is now possible.
It supports external trigger input, which synchronizes external events with EEG data in millisecond increments. Furthermore, our proprietary technology (patent pending) enables wireless synchronization by branching the audio signal for trigger input. This enables accurate timing recording of auditory stimulus presentation (ASSR, ERP, etc.) while maintaining a completely wireless measurement environment.

LSL connection, OSC transfer,
Seamless from measurement to analysis.
Accelerate your research with intuitive software and open connectivity. Supports LSL (LabStreaming Layer) connection and OSC transfer as standard. Accurate synchronization with eye trackers and VR systems is achieved down to the millisecond. It also provides powerful support for advanced offline and online data analysis using Python (e.g., MNE-Python) and MATLAB (e.g., EEGLAB).

The gold standard of research,
Data quality.
We conducted simultaneous measurement experiments with existing wet-type research EEG devices, objectively proving that the VIE EEG Headphones have extremely high equivalence.



The results of the resting state task showed that under eyes-open resting conditions, the correlation coefficient with the wet-type research EEG was extremely high, at 0.99 in the power analysis and 0.99 in the relative power analysis. Under eyes-closed resting conditions, even higher correlation coefficients (Power: 0.99, Relative Power: 0.99) were obtained.

The results of the MMN (mismatch negativity) task showed that when earlobe referencing was used with the wet-type research EEG, the correlation coefficient with the VIE EEG Headphones was an extremely high 0.99 for the difference waveforms. These values indicate that the dry-electrode and wet-type research EEG capture virtually identical waveform patterns.

The results of the P300 task showed a correlation coefficient of 0.99 for standard stimuli and 0.99 for target stimuli.

The results of the ASSR task showed that the time-frequency maps of both devices were highly similar. This brain synchronization response did not appear immediately after the stimulus onset (Time = 0 seconds), but rather occurred with a delay of approximately 0.1 seconds, indicating that it was not a physical vibration but rather brain activity.
Research-grade EEG data,

Blending into everyday life,
Bring brain waves closer to you.
I joined VIE about four years ago with the goal of "industrializing Brain Tech." For industrialization, it's important to develop applications based on neuroscientific evidence. I believed that a simple EEG device with the same level of measurement accuracy as existing medical and research devices was necessary as the foundation for this, so I cooperated in its development. The completed device's greatest feature is its ability to measure EEGs with roughly the same accuracy as existing research EEG devices, even on the scalp where hair is present . Furthermore, it responds to external triggers and is capable of measuring event-related potentials . This makes it ideal for applied research that envisions measuring EEGs in real-world environments, and I'm confident that it will usher in a new era of Brain Tech.
Q. What is the difference between the VIE EEG Headphone and a conventional wet electrode EEG device?
A. The biggest difference is the ease of setup and the flexibility of the measurement environment. VIE EEG Headphones' unique dry electrode technology allows you to start measuring in about one minute without the need for gel or other preparations. This makes it possible to conduct long-term measurements in a more natural environment, which was difficult with conventional wet electrode EEG devices, and to conduct experiments that minimize the burden on subjects such as children and the elderly. As for data quality, as described on this page (Section 5), a high correlation has been confirmed with the wet electrode method.
Q. In what format can EEG data be output?
A. The dedicated software "VIE Streamer" supports export of raw data in CSV format and EDF format, which is the standard format for EEG research.
Q. Can I access the raw data in real time?
A. Yes, it is. Because it supports LSL (LabStreaming Layer) as standard, you can access real-time EEG data streams and develop your own applications using familiar development environments such as Python and MATLAB.
Q. Is precise synchronization with external events (trigger input) possible?
A. Yes, it is. It is equipped with an external trigger input port. Furthermore, our unique technology (patent pending) enables wireless synchronization by branching the audio signal and inputting the trigger. This allows accurate timing recording of auditory stimulus presentation (ASSR, ERP, etc.) while maintaining a completely wireless measurement environment.
Q. Can I check the impedance (contact status of the electrodes)?
A. Yes, you can check the impedance of each electrode in real time on the dedicated software "VIE Streamer." This allows you to ensure good data quality before starting measurement.
Q. How long does the battery last?
A. The battery can run for approximately 7 hours during continuous measurement.
