We have the small speaker bought our camper around him with iPhone, iPad and iPod nano to use old (via jack cable). It is truly amazing what a good sound coming out of this tiny speaker. Of course, here there is a lack of a powerful bass, how do these also come with the package size? But for the purposes of the sound of a small camping bus, the thing is really more than sufficient. Really long experience we have not yet, about the battery life, we can not say much. We use the part mainly for listening to music or for amplifying the sound of the iPad Mini with the film look. Only two points ensure a star deduction: It does not work to pair the speaker with another device without turning off the Bluetooth connection previously on the original device. So first off Bluetooth on the iPhone and then connect to the iPad. The annoying bit. And the supplied bag (basically good one is) is a bit too small, so they can not be completely closed to the corduroy suit. All in all, just little things, but a little something must complain to you so do not have, right?
