And like the Parrot Zikk's, you can flip through tracks and adjust volume by tapping on the right earcup. Four dimples on the right earcup control a variety of actions, like posting what you're listening to from Spotify directly to Facebook or Twitter. An accelerometer makes the Muzik even more intelligent so they stop playing when you take them off your noggin."
