French neurotech company Naox Technologies is making waves at CES 2026 with a new announcement. The company has introduced Naox Wave, a pair of wireless earbuds that can measure your brain’s electrical activity using electroencephalography, more commonly known as EEG.
EEG is the gold standard for tracking the brain’s electrical signals in clinical settings to study sleep patterns, stress, concentration and neurological diseases.
Traditionally, EEG requires a hospital setup with about 20 electrodes stuck to your scalp, but Naox wants to make it something you can wear like regular wireless earbuds and use in everyday life.
Naox’s in-ear approach aims to make this process much easier by placing discrete sensors in your ear that passively capture brain signals as you go about your day.
How Naox earbuds convert brainwaves into health insights
Naox Wave earbuds are based on the same in-ear EEG architecture as Naox Link, a wired, FDA-cleared clinical EEG system already approved for professional use. However, the wireless Wave version is aimed at monitoring consumer well-being, not medical diagnosis.
The system tracks biomarkers such as concentration, relaxation, alertness and even indicators related to cognitive patterns. A companion app processes this data into easy-to-understand results and trends, so you can see how your brain activity changes while you work, rest, or sleep.
Instead of leaving raw graphs to users, the NAOX app converts EEG signals into simple visual summaries and offers guidance like breathing exercises or curated audio experiences based on your state of mind.
Naox’s broader vision is for this EEG technology to be used in earbuds from other audio brands, meaning your next pair of favorite earbuds could one day track your brain activity quietly in the background.
The launch of the Naox Wave earbuds is expected to begin towards the end of 2026, with pricing and product details pending.
Other tech companies are also exploring brain health monitoring: Samsung is developing a feature to detect early signs of dementia on its wearables, and Timex is working on a wearable sensor that will monitor brain activity, not just heart rate.
What was once a cumbersome, clinical process now feels closer to everyday wearable technology, turning brain signal perception into a fascinating new level of personal wellness monitoring.
