I do wish Id ordered the next size up. I was concerned about these being a low quality copy of another brand, but I was delighted by how well they held up. I would look at other shoes. I also just love the colour. No me gustó la forma de adelantar o atrasar la música ya que se realiza con el mismo botón de play y supone un mayor desgaste. This could simply be the insulation that causes this, as I have definitely experienced the same with boots. These are excellent at noise cancelling and fully immersing yourself in the music. Worried the stretch material may wear out. Only tiny con is that the Velcro closure is admittedly a little odd, but it holds well. I did experience driver flex with the CSA with most of the silicone eartips I tried.
