In order to read your brainwaves, you are going to need a smart EEG sensor as well as a software that can make sense of your data. The Emotiv MW20 does both and more. It is a pair of Bluetooth 5.4 earphones with a dual channel dry‑electrode EEG sensor and 6 beam-forming mics, so you can use these to listen to music, measure your brain activity, and enjoy noise cancellation.
The MW20 features 11 mm Beryllium drivers and hybrid adaptive ANC. It reads your brain activity and translates the data into 15 cognitive performance scores, so you will know when you need to take a break, meditate, or stay focused. You can use this gadget to monitor your cognitive age over months and even control games. The EEG function can be turned off. This project is getting funded on Kickstarter.
