TVs have grown thinner than DJ Qualls. That’s good. But they’ve also lost the ability to pump out quality audio. That’s crappy. The Sonos Playbar ($700) is raising its hand to help. Souping up the standard sound bar, the Playbar wirelessly streams music and plays anything that’s plugged in to your HDTV: cable/SAT boxes, Blu-ray players, and game consoles. Of course how it actually sounds is the key question here, but with 9 speakers (three tweeters and six mid-range drivers), Sonos says this thing will kick ass.
