I looked it over and figured out it was the pin system that you screw in through the receiver opening that was the problem. Just bought 3 more pairs as the whole family fights over who gets to wear the pair we have. These seem fine for your average consumer. These did have a chemical smell when I first received them but it went away after a couple of days. Most wireless headsets are too big for my ears or they just dont fit very comfortably and tend to fall off my ears frequently. My pictures dont show the touch of brown/bronze that makes them a unique but not gaudy appearance. I found its perfectly fine to tuck it behind the heel band or just let it hang though. Will be a nice jacket for early fall but definitely wont be the kind of thing Ill wear outside in the winter. Unfortunately Im still out $50. Great sandals, good price and very fast delivery.
