The Sonos One Smart Speaker is on sale for $156.50 during Amazon’s Black Friday Sale. This is the new lowest price that this speaker has ever been. The Sonos One was just released and has Alexa capabilities built in that make it work like the Amazon Echo. It has far-field microphones that listen for the Alexa wake word so you can control it with your voice. The Sonos One is considered by most to be the best sounding Alexa speaker on the market. Also on sale is the Sonos PLAYBAR TV Soundbar for $529, which is also the new lowest price it has ever been.
