Wireless speakers

While In have a dedicated room for serious listening , I would like to add some wireless speakers to my living room for music in general and when company comes over . I will probably just stream from my phone . I have tried Sonos products but found them to be rather mid- fi than hi-fi  sounding . Has anyone added a second source of music to their home  using current wireless technology and was pleased with the results for what I would call general listening ?
