Accurate: Equipped with advanced EEG technology, the EEG Tranquility headband uses its 3 biosensors to collect the user's brain signals during meditation. Then, based on the user's brain activity, it senses when your brain is distracted or focused, anxious or calm, and translates your brain activity into simultaneous audio feedback. 
 
Useful: When your mind is distracted and anxious, you will hear a constant white noise sound; when your mind is deeply focused and calm, you will hear a chirping white noise sound. 
 
Healthy: EEG Tranquility helps you establish a long-lasting meditation habit, substantially improves your focus, productivity, and mental health on a daily basis.
