The most versatile smart speaker from bose—a home speaker, a portable speaker and a voice control speaker, all in one
Enjoy 360 degrees of deep, clear, lifelike sound and powerful bass, no matter where you play it, no matter what you listen to
Around the house, you can move it from room to room—and out of the house, you can take it with you wherever you go
Within range of your Wi-Fi network, control the speaker with your voice and use it as an Amazon Alexa speaker or your Google Assistant speaker to play integrated music services like Amazon Music, Spotify and Pandora
