Its such a useful item and looks good to boot. Before it was all the same soft leather. I wear a size 6 for almost every shoe. But theres just still that little more hassle compared to wired earphones. I would expect a wired headphone to plug into my phone and sound to come out. i would say go 1/2 size bigger not a whole size. As most of you are aware of owning on/over-ear headphones, no matter how well you take care of them (mine always go back in their case when not in use) the earpads are always the first thing to go. En la caja sólo viene el reloj, instructivo y cable cargador. So I bought a size 9 (In their size) per the reviews I read. There is no sound difference, however, these can create a little more “suction” to my ear.
