Features
Sonos Combo Adapter: The Sonos Combo Adapter turns the USB-C port of the Sonos Era 100 and 300, as well as the Move 2 (sold separately) into an Ethernet port and Aux input, so you can make a hardwired network connection to your router, plus connect an external audio source device that lacks WiFi or Bluetooth.. The Sonos Combo Adapter is 7.875" long and features a male USB-C connector on one end, plus an Ethernet (RJ45) port and female stereo 3.5mm minijack on the other end.
- If you want to connect a turntable to a Sonos Era 100/300 or Move 2, you'll also need a phono preamp or a turntable with a phono preamp (sold separately) in addition to the Sonos Combo Adapter.
- The Sonos Combo Adapter is not designed for use with a TV and will result in some latency or lip sync issues.

Works well. Combined with a Wifi Extender that has a LAN port, I have been able to eliminate an unstable wireless connection (due, I think, to wireless channel crowding).
