I have a good piece now for 10 days and am very happy with my decision. The unit keeps its promises. Design and manufacturing are well. Coupling with smartphones and iPads (regardless of whether directly or through BT NFC) are simple. As a result, it is sufficient to turn the box and to activate the phone or IPad BT (when it should not always be activated) and already is a fine and clean sound out of the box.
The battery capacity is sufficient in any case. Have 2 nights without charging music heard and then charged. Whether because the battery was empty, I do not know, but I want to take a full charge the next day the part. When the unit is connected to the mains, can sometimes charge his cell phone or tablet via the USB connector.
Another thing: the Quick Start Guide I have flown over only on day 6 times!
So if a good BT-Box is examined visually so expect the Philips BT5580 well served.
