Developed by Japan-based Neurowear, the Mico headset looks like a regular pair of headphones, with the addition of an EEG reader that rests on the forehead and senses neural activity. Analyzing the signals enables the device to detect the mood of the wearer, which it exhibits using an LED display on the earpieces. When connected to the Mico app, this information is used to select a song from its database that matches the emotion. Currently, the tracks in the library are tagged with one of three moods – focused, sleepy and stressed. As well as getting rid of the step of scrolling through thousands of songs to find one that suits your mood, Mico headphones also provide a Pandora-like service, helping users discover new music.
