Indeed, this small speaker follows me from room to room. As effective as the descriptions on the Amazon site (and other sites it must be said, too) can show it. An incomparable sound, unparalleled ease dappariement as well with the iPhone than the iPad or smartphone and a Adroid Nexus7 tablet. There are also what some see as a gimmick or futility, I mean the way "free hand" with the smartphone, well it is super effective. At the other end of the line means to me like I was talking directly to my smartphone and not through an enclosure a few meters from this phone. I expressly recommends that all those who want to have sound and be free to move.
