While the world chases AR glasses, a 45-person Vietnamese startup is quietly building the next computing interface right inside your ear. Earable isn't selling headphones—they're engineering a brain-computer interface disguised as a wearable.

"The best interface is no interface—until your brain becomes the interface."

The 'earable' category is heating up—Apple's AirPods Pro 2 already has FDA-cleared hearing aid features, and startups like NextMind and Neurable exited. But Earable's approach is different: they're not just reading brain signals; they're stimulating them. Their tech likely combines EEG, acoustic stimulation, and haptic feedback to create a closed-loop system that could treat insomnia, enhance focus, or even augment cognition.
