PRODUCT DEFECTS:After some hours of use you can hear audible popping in the right ear where the ANC circuit is. I also like that you can actually walk in them--not always a given with ladies shoes. Sound is good but while using using sound is decreased. There shoes look absolutely beautiful, surprisingly comfortable. Save your money as they are useless. Ive been air drying them instead of using the dryer, just to baby the elastic, and because they dry fast. Essendo prodotti originali, la misura è naturalmente quella brasiliana. The texture is tactile and feels nice while the case is rugged and study. No headache and rarely adjust the band on top, even after a full workday. I gave up on trying to make the little labels look even and perfect.
