Libratone isn't content with churning out more cloth-covered wireless speakers -- it wants to muscle in on Sonos' home turf. The upscale gear maker has launched both an updated Zipp speaker and a smaller Zipp Mini (shown above) that include multi-room audio. You can link as many as six of the zipper-clad speakers over WiFi, much like some of their peers. The key, as you might have guessed, is that everything is portable. If you're jonesing to move your entire setup to a new room, you can do it without feeling like you're moving house.
