The series

01

Device control

Neural Earbuds Unlock a New Control Layer for Consumer Devices

Consumer neural sensing is entering through device control, from gestures and jaw activity to silent speech. In-ear EEG adds a deeper layer by linking those interaction to cognitive state.

02

Sleep monitoring

How EEG Earbuds are Transforming Sleep Monitoring

EEG earbuds are moving sleep monitoring closer to direct brain measurement, using in-ear signals to capture sleep architecture and support adaptive audio intervention across home and research use.

03

Productivity

Brain-Sensing Earbuds Open a Window into Productivity

Brain-sensing earbuds are moving productivity tools from subjective focus tracking toward contextual cognitive-state data, with EEG earbuds tracking longitudinal data and providing key focus metrics.

04

Brain foundation models

From EEG Classifiers to Brain Foundation Models

EEG foundation models mark a shift from task-specific classifiers toward reusable neural encoders, with in-ear EEG emerging as one route to real-world brain data.

05

Market overview

Inside the Next Phase of Consumer EEG

Consumer EEG is expanding across sleep, cognition, and device control, but wider adoption will depend on integration into familiar everyday hardware.
