Connect a wired 3.5mm audio source to your speaker with this black Sonos Line-In Adapter for Era 100/300. Simply plug one end of the cable into the USB-C port of the Era 100 or Era 300 speaker, and use the female 3.5mm end to connect a wired audio device or component, such as a turntable. Please note that the 3.5mm auxiliary cable needed is not included.
Check length of cable before purchase. It's very small - less than 6 inches. How can I connect two devices with such a short cable?
You don’t get to see the options in the Sonos App for the Line-In adapter until you actually connect it. So, you’re not able to see that the lowest latency possible is 75ms. In other words, the timing is, at minimum, 75 ms slower than the source. Not useable with video
