These pair fits perfectly well and the soles are very comfortable too. This enables you to see your shoes and find them fast when in a hurry. In the end, I?m happy with my purchase. bad sound quality. A few other differences between the two is that the ONEs are an all-plastic design, whereas the ZEROs have a metal rod connecting the ear cups to the headband. They feel totally secure which is pretty important. Im not a glitter type girl, but I felt beautiful in it. As to the fit- Im 510" 260 and got size XXL. So, if you are planning to use this product with a standard T Track Bolt, it will not work. El modelo me encantó, hice la devolución porque viene muy reducida la talla y el empeine, pedí la talla 10 (7) mex.
