iPods and iPhones and Androids and computer hard drives can keep expanding in size until the end of life as we know it, but until they stop releasing Greatest Hits collections by Queen, we’re going to keep filling the space. We’re all media pack rats. It doesn’t matter if you only listen to the same 100 songs on a yearly basis, if you can’t have fingertip access to ALL 10,000 of the tracks in your library, it isn’t good enough. Which is where the Sonos Play:3 comes in. Designed to attach to the Sonos Bridge ($50 if you don’t already have one), these wireless speakers double as media streamers and give you access to everything in your local library – along with libraries from Pandora, Napster, Last.fm, SiriusXM, Rhapsody and every other streaming service out there. When you want to expand your system you don’t even have to run wires. Buy another Play:3, push the button and voila, instant multi-room sound system.
