Sonos Sum
Sum is a portable speaker concept for Sonos, designed to be paired on-the-go with nearby Sums. At a picnic, in a car or at a party you can create a symphony with friends with individual Sums linked up.
Conceptually, Sum can be added to existing Sonos systems via WiFi network or a group of Sums via Bluetooth if outside with the Sonos app.
