With an audio streamer from Sonos, you can improve the WiFi connection between all your Sonos devices. This way, you experience less problems with malfunctions and stutter caused by a bad internet connection. This is useful if you have a multi-room setup, for example. In this setup, your speakers are divided over several rooms. Even in the rooms where you have a less stable WiFi connection. Or choose an audio streamer to connect random HiFi sets to your Sonos system.
