 This is Elizabeth Lopato with The Verge. I'm here holding a MyBrain Mellow device. It's meant to measure EEG. What it does essentially is provides a reading of brain waves, then goes to your smartphone and helps you relax. The idea is this. You put it on, and then you put in headphones connected to your phone, and music flows through to sort of give you a sense of how relaxed you are and maybe to relax you further. The device is in pre-order now. It's about $285. For more information on technology coming out of CES, please subscribe to our YouTube channel.
