[Muse is a brain sensing headband](http://www.choosemuse.com/) for assisted meditation. It pairs over bluetooth with your phone to guide you through a meditation session with realtime feedback on your brain’s activity, followed by some stat tracking that helps you improve your calm over time.

Disassembly revealed a circuit board behind each ear. This side contains the battery and charging circuitry, as well as an opamp and several test points.

The traditional circuit boards are joined to a flex circuit with a sophisticated adjustable metal piece. A small clip extends down to connect to the metal part of the exterior enclosure, which provides contact to the conductive rubber over-ear sensor.
