My original ear pads started to become loose and the stuffing started coming out. So I decided to look for a replacement, I didn't realise there was a cheaper option than going to the bose store and paying almost 40 dollars. Happy with my purchase, they fit well and comfortable. They are easy to change you just clip them in, just to make sure I watched a video on youtube that showed you how to. Very easy. The quality is not as good as the real deal, but it is pretty close.
