For this size just a treat for the ears. I do not know how contrives the Bose accommodate such a great powerful sound in such a small box. Connections between iPhone 5s and iPad fold immediately, just great. Silk I have this box, I take no other device to play more of my Musik.Nachtrag from 08.16.14, the box is now able to test single pair days where I am not at all satisfied, the Bluetooth connection. Leaving his cell phone lying next to the box's all good, if you hold it to charge a little further away to catch the disturbances and interruptions to. This can mean cheap box for 50Euro better Sorry that is not at all, not for 180Euro.
