This equipment has rather good sound compared to its size. The settings are simple but effective. Its USB adapter is convenient and provides correct positioning of phones (ACE Sansung S4 and 4) but not quite stable: this can make some febrile users! 1 downside: the blue light (bluetooth) which is a bit too strong for my taste. Furthermore, and I thank the Amazon customers who responded, for a wake to music, install an application on your phone other than the one proposed by Philips or that natively on the Samsung phone.
