The portable $399 Sonos Move is like having two great speakers in one

Sonos has released their first-ever portable speaker with a built-in battery: The $399 Sonos Move, which starts shipping to customers on September 24. After spending a few days with the Move, I can confidently say that it offers everything that's great about the Sonos wireless audio system, but with all the added advantages of a speaker you can freely move around the house -- or take with you on the road. The company set about designing a different speaker because the Move will suit different uses versus the One, as it's designed to be used in all environments, including outside in open air.
