Cue up the eight tracks


Many people have at least one old sound system lying around the house (boom box, anyone?). Yet most people today store music on laptops, iPods or smartphones. Rocki provides a bridge between the two. This tiny $49 music-streaming device connects wirelessly to any system and is controllable via smartphone. Cart around all your favorite albums on your phone, drop the Rocki next to whichever stereo you want to blare your tunes, download the related app, and voilà: good music and good sound.
