Cumple con los requisitos I bought an 8 because everyone said they ran big. It also sucks up an inordinate amount of space in any camera bag you bring to the party. The boom is the perfect length and stays just out of the way. también estuve investigando largo y tendido sobre cables y yo combiné esta compra con varios cables marca ugreen que puedes buscar como "UGREEN Cable USB Micro USB Nylon Trenzado", que encuentras en tamaños de medio metro, 1 metro, 2 metros y 3 metros. I purchased this earpiece and used it for about a week and it started giving me trouble it was uncomfortable and you couldnt hear the phone ringing you could barely hear the people you were talking to it sounded like they were in a tunnel or they had something over their mouths when they spoke so for me not that great of a bye I was referred to this shoe by a friend. Starting cutting out after a few weeks should have known it would stop all together. I can barely feel them at all. The soles seem strong, and are definitely padded so I can wear them in multiple places, even on quick rides.
