The top will not stay on, I even used an adhesive promoter, the first 3 times I found it, but this last time, it?s gone for good. So I am waiting to have that heal to wear them again. (Sony somehow manages to do okay with portraits and direct flash for casual-events, Im not sure how they managed this. While others indicated having trouble connecting through Bluetooth, I found the instructions were well laid out: turn on the mouse, press the mode button to select either "2" or "3," and long press the mode button again, until the light blinks fast, then its just a matter of going into the respective Bluetooth settings, scanning for new devices, and then pairing it up. So far it seems to. They are very loud and the quality of sound is amazing at this price. Good support (maybe not enough for running), super comfortable, and also SO flattering. They are a good quality, and his out grown pair still looked like new after a year of wear. This one is particularly solid, they must use a thick cardboard because there isnt much flex. Plus the box very beat up.
