Meet the Aware: a special headphone with bio and brain sensors to monitor your sleep, daily activity, and stress. These headphones are 3D printed and fit perfectly. They connect to your smartphone via Bluetooth. You get EEG/EMG/ECG sensors, noise-cancellation technology, a 9-axis accelerometer, and a pulse sensor.
Using this device, you will be able to monitor your sleep, activity, and focus. You can also simply store and listen to music. The product is getting funded on Kickstarter at this time.
