Very fast shipping, one of the fastest so far to my region.All you need to know is that there are 10 hooks which have to grab the ring behind the pad.See the 2nd picture all 10 hooks are encircled in Green . once the hooks are firmly in place your Pad will be a perfect fit. Once the hook is in place you can see it on the ring See 3rd Picture hooks are in green circles. you will also hear a distinct click sound once the hook is in place. The replacement pad is on Left side and original on Right side see 1st pic for reference
Headphones are as new - a little tricky to fit though.
