Picture a remote in your mind. What did you see? A long, rectangular black box with some rubbery buttons on it? Because that's what 99% of audio systems ship with, despite the fact that the iPod proved long ago that's not a good interface for controlling your music. The Bang & Olufsen Beosound Essence ($1,000) is closer to what it should be. This Nest-sized remote can sit or hang nearly anywhere, controlling a hideaway box that offers power for a set of stereo speakers, as well as Wi-Fi for AirPlay and DLNA streaming, and direct connection to Spotify, QPlay, and other Internet radio sources. An ideal companion for B&O speakers.
