Well I give back my feeling that soon changed, finally the name is displayed not "THAT" if I open the app that I stay over I run a sync between the smartphone and the bracelet and if I make a test incoming call, so the name is displayed, beyond that, they are never displayed, so after 2 months of use I am disappointed anyway, even if the headset works rather well, the battery is bonne.Mais it does not bring me the first service I was expecting, I think even the board handsfree earphones
