The wireless speakers ZIPP and ZIPP MINI (first generation get) a software update from Libratone.

This now allows to use Apple’s extended streaming protocol AirPlay 2 with these loudspeakers. The protocol allows several loudspeakers to be controlled from one iOS device with precise temporal playback. So there are no sound shifts or doublings but simply a uniform reproduction of the sound either in stereo mode or in different rooms. The update is available via the Libratone app.

But beware, if you control the loudspeakers from a Mac via iTunes and have done this parallel to other AirPlay 1 devices so far: the Libratones don’t seem to like that anymore. So you better decide about the usage scenario beforehand.
