I watched the Sennheiser video on how to do this, but still I had a hard time getting the pads on all the way around (when Id get one side on, it would slip off the other side). That said, they fit well, are pretty comfortable and arent constricting at all. These headphones feel very modern and stylish compared to the bulky and outdated XB950BT. Buena calidad de material. I however refused to buy the phone holders that are specific for a phone, because if you have a case, they do not fit. Nothing hard to set up wires would not charge phones had to use phones original wiring. If you walk more than half a mile in them, the ridges on the bottom start to leave blisters along the tips of all your little toes! The price tag on each is STEEP. Its high quality faux fur on a hard wedge. One of the characters always wore heels like these.
