Damaged 2 mtn bikes when they fell over in this rack! They promote how amazing their "Hyperspeed Connection" is but its god awful. a construção do produto é feita de plástico, a alça dele é de um plástico duro e fino, com pouca "elasticidade" o uso comum do dia a dia fez com que a alça quebrasse com menos de 3 meses de uso. If youre using one bud at a time, and you have the other in the case, they promise 28 hours. It works, HOWEVER. Super easy, now fits to a comfortable loose like most crocs fit. Notes: this cover plate adds a little but of a bump where the OEM cover is and essentially fills in that gap / dip Sony has from the white to the black. Im not sure how well it would hold up for really large shoes, like a mens 12 or 13 though. I have a pair of 1more which walks all over these headphones. If you have a problem like me, you are screwed.
