There is a shelf at head height. they fit narrow, and the black leather part cut into the top of my foot some. You cannot hear yourself in your headset. The bottom part, Part B, had holes in the wrong place. Ive almost lost one of buds multiple times but luckily it had not fallen in the sewer. If they ever lose their shape or wear down over months of use, I would just buy again. Have been using them for about two months now and feel more and more that this is money well spent. The bars do move which is nice and towels stay in place on it . They are there though! When I come home and take them off his feet are warm to the touch.
