These arent hifi, nor did I expect them to be. So it seems you get what you pay for. WE are going to try to repair the shoes on our own because my daughter loves them. My daughter has narrow feet and these were simply too wide. Das GPS 350 ist an sich nicht schlecht, der Sound ist super und die Microqualität auch, vorausgesetzt man benutz die mitgelieferte Soundkarte mit Treibern. This is really shoddy quality and its too late to return. What kind of nonsense! The sound quality as I would expect from Shure is exceptional, I?d say. Need BrcmPatchRam3 and AirportBrcmFixup to fix it. Now that Ive worn them more, the ankle strap fits a bit better, but I still wear them on the loosest hole.
