We're big fans of the Sonos Wireless home music system because it allows us to pipe high-quality music from our digital collection to every room in the house without running wires everywhere. In the past, it was a high-ticket solution. But this year, the company launched the Play: 3, a cute wireless hi-fi at a price that makes us happy. Grab one of these—and a Bridge to connect it to your Wi-Fi router—and you'll have a great starter system that you can add to over time.
$299 for Play: 3; $49 for Bridge, sonos.com
