BrainBit Headband

4-channel wireless EEG headband with free SDK for research, neurofeedback, and brain-computer interface projects.

BrainBit Headband is a wearable EEG device built as a flexible textile band with integrated electronics, dry electrodes, and a removable battery. It records brain activity from 4 EEG channels (O1, O2, T3, T4) and streams raw data wirelessly, so you can build your own neurofeedback tools, research setups, or interactive experiences on top of a ready-made hardware platform.

This version of the headband includes full access to the BrainBit SDK, so developers and researchers can go straight to experimenting instead of designing hardware from scratch. 

Key Features

• 4-channel EEG: Electrodes positioned at O1, O2, T3, T4 according to the international 10–20 system for robust temporal and occipital coverage.

• Dry, gold-plated, spring-loaded electrodes: Reliable contact through hair with no gel, caps, or messy prep

• Wireless connection (Bluetooth LE): Cable-free setup for lab, home, or field environments.

• Removable battery: Up to 12 hours of continuous use, with a charging time of up to 4 hours.

• Soft, flexible headband: Universal textile strap that’s comfortable to wear and easy to clean between users.

• High-quality EEG signal: 250 Hz sampling rate, wide 0–100 Hz band, and low-noise signal suitable for research and advanced neurofeedback applications.

• Free multi-platform SDK: Access raw EEG, brain rhythms, and artifact detection algorithms via SDKs for multiple languages and OSs.

Ideal For

• Neurofeedback training (focus, relaxation, mental performance)

• BCI and HCI research - brain-controlled interfaces, interaction experiments, and prototyping

• Meditation and wellness apps with real-time brain activity feedback

• Cognitive and behavioral studies in labs, clinics, or universities

• VR/AR and immersive experiences using EEG signals as an input stream

• Esports and performance training where brain states and attention need to be monitored over time

SDK & Software Ecosystem

BrainBit Headband ships with a free Software Development Kit (SDK) designed for both rapid prototyping and production-level integration.

SDK languages:

• Java, Kotlin

• Objective-C, Swift

• C++, C#, Python

• React Native, Unity, Xamarin

Supported platforms: iOS, Android, Windows, macOS, Linux

Data & algorithms available via SDK:

• Raw EEG data stream from all 4 channels

• Decomposed brain rhythms: Delta, Theta, Alpha, Beta, Gamma

• Artifact detection functions (e.g., eye and muscle activity)

Compatible with BrainBit’s own software, including NeuroFit PRO, NeuroREC, BrainBit Neurofeedback App, EEG Waves, so you can combine off-the-shelf tools with your own custom applications.
