The box shows black on the cover, but it is a white unit (as I ordered) which is perfect for my white Xbox One S controllers. Working from home means these comfy slippers get worn much. I doubt they are strong enough to hold much weight. Wednesday the pain starts, why do they fit this way? I try to stretch out the upper and put napkins & band-aids and cotton balls to try to ease the pain. These never, ever became comfortable. One rail has four allen screws, two on each side. Yup there are cons , when left and right headphones are joined by magnet while hanging songs dont pause , It has no IP rating so no water proofing . They fit well but feel a little tight around some of the bands on my feet. Is it the most beautiful headphone, certainly not but it does what i bought it for. Si bien no será lo mejor que se pueda tener, creo que tampoco queda nada a deber aún para los más exigentes.
