Sonos is looking to market to the iPhone and iPod touch crowd with their new ZonePlayer S5 wireless music system. If you’re familiar with Sonos, you know that the price of entry has always been a bit high historically. The ZonePlayer S5 brings that price down to about $400. You plug it in to a router, and you are good to go with the ability to play your entire music library, as well as music from services like Rhapsody, Napster, Last.fm, and others, by using your iPhone as the remote control.

The price rises if you don’t have an Ethernet port handy for the S5, as you would then also need to buy a ZoneBridge, which allows you to connect the ZonePlayer S5 (as well as any other ZonePlayers you have) to your network wirelessly. We definitely think this is a positive step in the right direction for Sonos. By adding an all-on-one ZonePlayer/speaker to their line-up at this much lower price point, they’ve made it enticing to check them out to see what all the fuss is about. We’d pick up a ZonePlayer S5 over a Bose Sounddock any day of the week.
