A little hard to implement at first but then it's a breeze. (Slide to fit system) used with my Galaxy Note 3 for long journeys by bicycle. The earphones are well maintained once established. The sound is good even at maximum, the power is sufficient (eg, putting the sound thoroughly, hardly refers to cars) Hands free kit, my interlocutor told me that the sound was clear, from my side no problem.
little flat after several hours of listening and pulling on the cable without meaning to, it can do some earache (ultra mini pain)
