A personal meditation assistant, Muse's brain-sensing headband eliminates the guesswork out of the practise. The voice of a meditation teacher or soothing soundscapes plays through your Muse S, helping even with pre-sleep patterns. Your brain activity, heart rate, breathing patterns, and body movements are all tracked, enabling your meditation teacher to offer feedback in real-time. With its soft, breathable stretch fabric, designed for overnight wear, falling asleep with Muse S is a breeze.
