This page describes products and general use; it is not medical advice.
An EEG headband is a head-worn device that carries electrodes to pick up the brain’s electrical activity. Whether it is a medical device or a consumer wellness product depends on what the maker says it is for, not on its shape. Clinic staff, buyers and students can use this page to see how FDA defines an electroencephalograph, how a full-montage clinical system differs, and where the general wellness policy draws its line.
What is an EEG headband?
An EEG headband is a wearable that holds electrodes against the head so that a recorder can capture brain activity. Under 21 CFR 882.1400, an electroencephalograph is “a device used to measure and record the electrical activity of the patient’s brain obtained by placing two or more electrodes on the head.” A headband or headset that does this fits the same identification as any other electroencephalograph. Who uses it: clinicians and technologists for clinical recordings, researchers, and consumers for products marketed as wellness devices.
How is an EEG headband built?
The only build feature the regulation fixes is the one above: two or more electrodes on the head, connected to a device that measures and records. Electrode placement on the scalp follows named conventions such as the 10-20 system, and a conductive gel is one material used between electrode and skin. For a different bioelectric recording, see what an ECG machine is.
What types of EEG headband and headset exist?
The table sets out how FDA’s own records classify the clinical end of the range and where consumer headsets sit relative to it.
| Item | What the source says | Source |
|---|---|---|
| Electroencephalograph (general) | Measures and records brain electrical activity using two or more electrodes on the head; Class II (performance standards) | 21 CFR 882.1400 |
| Full-montage standard electroencephalograph, product code GWQ | Acquires, displays, stores and archives EEG signals using a full montage array (16 or more electrodes) at user-specified locations; device class 2; regulation 882.1400; Neurology | openFDA device classification |
| Wireless and headset-format clinical EEG systems | 510(k) records under GWQ include the Neuroelectrics Enobio Wireless EEG (K162681, 2017-06-02), Advanced Brain Monitoring X10/X24 headset (K131383, 2013-11-27) and Nihon Kohden Wireless Input Unit WEE-1200 (K171124, 2017-08-25) | openFDA device classification |
| Consumer or wellness headset | Software for maintaining or encouraging a healthy lifestyle and unrelated to the diagnosis, cure, mitigation, prevention or treatment of a disease or condition is not a device | FDA general wellness policy; FD&C Act 520(o)(1)(B) |
Consumer EEG headset versus clinical EEG
A consumer EEG headset is a head-worn wearable aimed at a general-wellness use. The regulatory difference lies in the stated purpose: a product used for diagnosis or treatment of a condition falls under the device rules, while one limited to a healthy lifestyle purpose may fall under the wellness policy. Shape does not decide it, as the wireless headset 510(k)s above show.
How do medical and wellness EEG headbands differ in regulation?
The regulatory distinctions are:
- The maker’s stated intended use matters. A diagnostic or treatment purpose points to device regulation; the wellness policy covers products that promote a healthy lifestyle and are unrelated to disease.
- Clinical recording systems carry a 510(k) record. Full-montage systems of 16 or more electrodes are classified under product code GWQ.
- Electrode count differs: the GWQ definition is built on 16 or more electrodes, while 882.1400 itself requires two or more.
Related equipment is listed under diagnostic, monitoring and imaging supplies.
Common mistakes
- Treating a wellness headset as a diagnostic tool. The wellness policy applies to products unrelated to the diagnosis, cure, mitigation, prevention or treatment of a disease or condition.
- Assuming a wireless or headset shape means a product is not a clinical EEG. Headset-format systems appear among the 510(k) records under GWQ.
- Assuming every EEG device has a full montage. The GWQ definition specifies 16 or more electrodes; the general regulation specifies two or more.
FAQ
What is a consumer EEG headset?
It is a head-worn device marketed for general wellness rather than clinical use. Its status turns on the intended use, under FDA’s general wellness policy (FDA page dated January 2026).
Is an EEG headband an FDA-regulated device?
A device that measures and records brain electrical activity with two or more electrodes on the head matches the electroencephalograph identification in 21 CFR 882.1400, a Class II device. Software for maintaining a healthy lifestyle and unrelated to disease is not a device under FD&C Act 520(o)(1)(B).
What class is an EEG device?
Class II (performance standards) under 21 CFR 882.1400; the full-montage product code GWQ is also class 2 in openFDA.
