The Muse 2 Meditation Headband is a wearable device that provides live feedback during your meditation practice. This feedback includes your brain activity, breathing technique, body movements, and heart rate while you meditate. Its purpose is to help you get the most out of your sessions. During and after meditating, check your data on the app. For example, tune into your heart rate to ensure that you remain calm. It'll even provide you with feedback so you can learn how to breathe properly to fight stress. Most importantly, the headband will play weather sounds while you wear it. The audio will respond to your brain waves to represent how you're feeling. For example, if your heart rate is fast, the rain sounds will get heavier. By using audio as a representation for your mood, this meditation headband helps make you more aware of your peace.
