Brain-computer interfaces (BCIs) are entering the mainstream through consumer wearables, such as glasses and headphones, offering real-time neural feedback in everyday form factors. These devices use non-invasive EEG and biosignal sensors to translate brain activity into actionable data—enabling more intuitive, adaptive user experiences.

One standout is Snap Inc., which acquired NextMind, a Paris-based neurotech company. Their BCI technology enables users to control augmented reality (AR) elements in smart glasses using just their thoughts and attention. Future iterations of Snap’s Spectacles could allow users to interact with digital overlays without touching a screen, merely by focusing on an object.

In audio wearables, Neurable has developed Enten headphones that detect cognitive states like focus, fatigue, and stress through embedded EEG sensors. These headphones can dynamically adapt your audio environment—for example, lowering distractions when deep focus is detected, or alerting you to take a break during mental fatigue.

Meanwhile, Valve has partnered with OpenBCI to create Galea, a BCI-integrated headset that merges EEG with other biosensors. Designed initially for gaming, Galea enables games and virtual environments to respond to a user’s emotional and cognitive state in real time.

These brands aren’t just imagining the future—they’re shipping its earliest versions now
