Sonos, components range from $79 to $999 sonos.com ★★★★ You don’t necessarily go into a store and buy yourself a complete Sonos audio system. This is something you can build up, piece by piece. Our review unit came with a Bridge ($79) , two Play:3 ($419, three speakers in one), a Play:5 ($599, five speakers in one) and a Sub ($999). You need to physically connect one device to your router. That can be either a speaker or the Bridge which is a hub for the system. Adding another speaker is as simple as hitting one button on each unit. When you’re up and running, you can use the tablet/ smartphone app to play a different song on each speaker, or the same song.
