I recommand this item for purchase.
I've got a Sony WH-XB900N (see pictures) and bought this set of cushions.
Ordered them from France, so I had to pay a 5€ customs tax, but holy god is it worth it; all in a 13-day delivery (mind the customs slowing the process).
Mounting them was as easy as the original, mind the elastomere lip being a bit larger, but it still fits quite good!
The texture of micro-suede was something new for me and I love it, moreover I know it won't chip away like the original fake leather did...
If you've got a WH-XB900N, do not hesitate, get that pair of cushions :)
Thanks Brainwavz!
