Sonos is the leader in wireless multi-room music systems for the home. Their system lets users play ‘all the music, all over the house’, controlled easily from the palm of their hand. The Sonos team is dedicated to designing magical music experiences; internally, they’ve created a culture of user-focused design that leads the company’s products from sketch to store shelf. In return, Sonos’ consumer brand loyalty can be described as a cult of music-loving, Sonos-crazy customers. Sonos’ products are consistently rated with a Net Promoter Score of 80%, which means that when asked to rate how likely they are to recommend Sonos to friends and family, on a scale of 0 to 10, the majority of customers choose 9 or 10. This is good news for Sonos sales, and a clear indicator that customers appreciate good design.
