So we recently purchased 2 Sonos play 1's for my master bed and bath. I must say set up was super easy and I plan on expanding the system. I was shocked at the sound quality of such a small speaker.
Although as my wife pointed out, not a true "wireless" speaker because you need a power cord for each speaker
Love the SONOS app which allows me to control everything from my I pad or Iphone. Our wi-fi connection is pretty good (At&T Uverse) and the speakers play outside under the patio with no problem.
Unfortunatly SONOS does not make a weatherproof speaker although the speakers do play outside @ $200 a pop I dare not leave them in the elements.
We were first considering purchasing a bluetooth battery powered speaker for almost the same price, but after reading the batteries wear down over time we decided on the Sonos play 1's. very happy so far but only time will tell.
I'm totally hooked on these wireless speakers.
