Why do Smartbuds use EEG, and how does it compare to other sleep trackers?
Most wearables track your sleep by looking at things like heart rate, breathing, or movement. While these signals can give an estimate, they’re indirect—they can’t actually measure what your brain is doing.
Smartbuds use EEG (electroencephalography), the same technology trusted in sleep labs and clinical research. EEG directly senses the tiny electrical patterns of your brain, which are the gold standard for understanding when you’re truly asleep , and how restorative your rest is. The result: a clearer picture of your sleep quality and more accurate insights to help you improve it.
