Can’t decide what song to listen to on your Sonos speakers today? You should start with “The Bridge Is Over” by Boogie Down Productions. That’s because you won’t need the $50 Sonos Bridge to stream music to the company’s speakers anymore—but you may still want to use one in many cases. Sonos just announced a firmware update that eliminates the need for the Bridge, which had to be physically connected to a router with an Ethernet cable for any Sonos system to work. Now, you can connect to one or more Sonos speakers directly via Wi-Fi, with no hard-wired connection. During configuration, a speaker will form an ad hoc connection with your mobile device. You can set up one of the speakers to act as a wireless bridge for multi-speaker setups, although there are some limitations as compared to a Bridge setup.
