I wanted to control my remote enclosure without necessarily having to plug it in every time my iPhone. The iHome AirPlay system that does wonders for that side. And being able to move the enclosure (battery) in any place, provided they are not too far away from the hotspot, allows me to enjoy my music in a new way. A bathroom with me singing dolphins right next to me ... Question her, I am however a little disappointed. I expected more safe and deeper bass. But even pushed to its maximum volume, the speaker does not saturate and that's rather nice. Overall I am very satisfied. Caution: if you practicality happens after the sound quality, turn to another model.
