Using two wobie boxes at the same time? Is that possible?

Yes, it is possible to use two or more wobie boxes simultaneously. However, each wobie box must be linked to a separate Spotify account from your Spotify Premium Duo or Family subscription. Use with Spotify Free is also possible. You can switch between accounts in the Spotify app, so all wobie boxes can be controlled with one phone.

Please note that Spotify specifies that only one device per account can stream music at a time. This means that each device (e.g., a wobie box, your smartphone, or another playback device) must be connected to its own account to stream simultaneously.
