Bought 4st ZR5's and 2st zr7's on webhallens sale. Everyone talks about the Sonos but avid Android user, I do not want to lock me in a corner. So when Google this year updated its open Google Cast standard with a multi room and group function, so the choice was easy. There are a couple of weaker hardware to choose from and you can blend between different manufacturers. But I'm driving right now just Sony. But for 1390kr for a ZR5 and 2390kr for a zr7 it is impossible to find more for your money if you want a wireless fidelity sound. In the stores, so it sounds like Sonos is superior with his ljud..men do not be fooled by it, Sonos stagear and optimize their demoex in the stores, while Sony's speakers only exhibited without care.
The installation was basically painless (probably not as easy as Sonos) and the sound is very good. Is especially impressed by ZR5 which has an incredible sound for its size. Warm but not as loose as treble Sonos. Probably a little less bass than Sonos, but overall means a higher fidelity sound and infinitely more features. Moreover, I sit not in the lap of Sonos with their closed apple imagine without this in principle any appltillverkare can build support for Google cast. Safe on Google Cast icon on your phone appear all the speakers and groups up. Enklelt!
