Alcatel brought the whole family - two Idol 4 phones, Pixis of all sizes and even a Windows 10 hybrid laptop. The phones really like to party and have dedicated Boom button, which turns up the sound, launches the camera (and dose a few other things), while the stereo speakers can work in any direction you want.
