What if you could see exactly what your brain does while you sleep — and actually improve it in real time? The Muse S Athena is the world’s most advanced consumer sleep wearable, combining EEG (electroencephalography) and fNIRS brain-sensing technology to deliver 88–96% sleep lab accuracy right from your nightstand. Unlike fitness trackers that estimate sleep from motion and heart rate, the Muse S reads your actual brainwaves to determine precisely when you’re in light, deep, or REM sleep.

Who Is This For?

This is for the serious sleep optimizer — someone who has tried basic trackers and wants to go deeper. If you struggle with insomnia, light sleeping, or simply want to understand your brain’s sleep patterns at a clinical level, the Muse S Athena offers data no other consumer device can match. It’s also perfect for meditation practitioners who want neurofeedback-guided sessions.
