The build quality is more than light: the plastic is very uncomfortable (on the top of the skull in particular, for those who lack hair volume ...) and it is feared to break the volume control button as soon as the manipulates. The "leather" headphones is not pleasant either, and sound insulation vis-à-vis the outside world is very limited. In addition, it flashes every 6 seconds when used: not very convenient when people are trying to sleep close!
That said, the sound is correct, and the pairing is easy with Android device (tablet or smartphone).
