Josh wants to know if there's an alternative to SONOS that can broadcast music to each room in his house. Leo says that used to be the sole domain of SONOS. It's difficult to do because of latency. Now, other products are capable of doing it thanks to Google's Speakers. NEST Speakers do the same thing as Sonos, but so does Amazon wireless speakers. Leo really likes the Google Nest Speakers. They're ideal. NEST Audio Speakers are about $100 per.
Ultimate Ears UE Megabook speakers also do the same. But Leo says that Nest Audio is the way to go.
