If you dont believe this review, Google something to the effect of "Liberty Air 2 both wont pair". My one and only complaint is that at least for me, it is a bit tight around my thighs but seeing that it fits perfect around my waist, a size medium would be too loose. The sound, especially in the right earpiece keeps cutting out. Also, in the video I should mention that my phone has a case on it and it charged no problem. Consegna veloce e perfetta nonostante lemergenza. These fit in the outer ear and good ones like that are hard to find. My only complaint is that the bar fits a little loosely into into the wall anchors, so it jingles and rotates when you put a towel onto it. Ill update when its time to get the smaller size, but so far, Im super excited!
