cost 1/2 of dealer. Other than that the ones that do work work well I hacked at it pretty hard with a hammer to make it work which didnt make my apt neighbors very happy. ) was available. this is my second update! This dress is flattering and very well-made. Theyre very durable; I used them all winter as ear muffs lol the last pair i owned lasted through 2 winters. Turning Bluetooth off and on on my phone usually solves the problem. I would not have paid full price for them ($70 for cloth slippers is a bit much) but $40 on Amazon and these are a wonderful buy. It was immediately noticeable out of the box.
